1
00:00:03,040 --> 00:00:05,840
Speaker 1: Welcome to Stuff to Blow your Mind from how Stuff

2
00:00:05,880 --> 00:00:14,200
Speaker 1: Works dot com. Hey you welcome to Stuff to Blow

3
00:00:14,240 --> 00:00:17,239
Speaker 1: your Mind. My name is Robert Lamb and I'm Joe McCormick.

4
00:00:17,239 --> 00:00:20,279
Speaker 1: And in case you haven't heard, there is a big

5
00:00:20,320 --> 00:00:23,680
Speaker 1: thing coming up for our US listeners. That's right on

6
00:00:24,040 --> 00:00:31,120
Speaker 1: August one, a giant crab monster from another galaxy is

7
00:00:31,160 --> 00:00:34,240
Speaker 1: going to swim into the sky and devour our son

8
00:00:34,600 --> 00:00:37,240
Speaker 1: and we were all going to die. No, not our son.

9
00:00:37,360 --> 00:00:40,920
Speaker 1: That's where we get our light and stuff. Uh, not quite.

10
00:00:40,960 --> 00:00:44,680
Speaker 1: There is going to be a total solar eclipse sweeping

11
00:00:44,760 --> 00:00:48,640
Speaker 1: across the center of the United States on Monday, August.

12
00:00:49,880 --> 00:00:51,920
Speaker 1: Some people have asked us about it. I have asked

13
00:00:51,960 --> 00:00:54,480
Speaker 1: us on social media and said, hey, are you gonna

14
00:00:54,480 --> 00:00:56,280
Speaker 1: do anything about the eclipse? So we thought as a

15
00:00:56,320 --> 00:00:59,480
Speaker 1: special treat we would discuss the solar eclipse. Now, we've

16
00:00:59,480 --> 00:01:03,000
Speaker 1: talked about eclipses before in episodes like Gazing into the

17
00:01:03,040 --> 00:01:05,679
Speaker 1: Eclipse from May. I think that was one of the

18
00:01:05,720 --> 00:01:08,840
Speaker 1: first episodes of the show I ever did um, but

19
00:01:08,959 --> 00:01:13,200
Speaker 1: today we wanted to go deep on the total solar eclipse. Now,

20
00:01:13,319 --> 00:01:16,440
Speaker 1: this episode will have some practical tips for viewing a

21
00:01:16,480 --> 00:01:18,800
Speaker 1: solar eclipse if you're planning on trying to make it

22
00:01:18,840 --> 00:01:22,320
Speaker 1: to the line of totality for for this upcoming one.

23
00:01:22,440 --> 00:01:24,760
Speaker 1: But we'll also try to do our best to keep

24
00:01:24,800 --> 00:01:26,440
Speaker 1: it interesting for those of you who aren't going to

25
00:01:26,520 --> 00:01:28,120
Speaker 1: be able to view this one. Maybe you'll get to

26
00:01:28,160 --> 00:01:31,720
Speaker 1: view a solar eclipse wherever you are sometime in the future. Yeah,

27
00:01:31,800 --> 00:01:33,680
Speaker 1: So our hope is that this is an episode. Maybe

28
00:01:33,680 --> 00:01:36,400
Speaker 1: you'll play it in the car while driving up or

29
00:01:36,520 --> 00:01:39,640
Speaker 1: or while you're stuck in traffic driving up to UH

30
00:01:39,640 --> 00:01:42,360
Speaker 1: to the line of totality, or perhaps you'll play it

31
00:01:42,360 --> 00:01:44,560
Speaker 1: on the way back to make you better sense of

32
00:01:44,600 --> 00:01:47,760
Speaker 1: what you saw. You just saw a total solar eclipse.

33
00:01:48,000 --> 00:01:51,080
Speaker 1: Now let's talk about the you know, the celestial mechanics

34
00:01:51,080 --> 00:01:54,520
Speaker 1: of what was happening there. Alright, So a solar eclipse

35
00:01:55,200 --> 00:01:58,080
Speaker 1: or any eclipse really is an example of what's known

36
00:01:58,120 --> 00:02:00,480
Speaker 1: as a scissor gy. I think I used to pronounce

37
00:02:00,520 --> 00:02:02,080
Speaker 1: that word wrong. I think I was calling it like

38
00:02:02,200 --> 00:02:05,280
Speaker 1: sizzygi or well it's a word that's spelled s y

39
00:02:05,520 --> 00:02:12,600
Speaker 1: z y g y. So it really the dictionary factory. Yes, yes,

40
00:02:12,720 --> 00:02:15,000
Speaker 1: sissy gy is a word that comes from the Greek

41
00:02:15,320 --> 00:02:19,519
Speaker 1: susa Joss or susy goos and scissor giant meaning yoked together,

42
00:02:20,120 --> 00:02:22,400
Speaker 1: and of course a yoke. You've probably seen one of these,

43
00:02:22,520 --> 00:02:25,080
Speaker 1: especially if you've ever played organ trail. It's a solid

44
00:02:25,160 --> 00:02:28,800
Speaker 1: cross beam that attaches two animals by the neck. So

45
00:02:28,880 --> 00:02:32,120
Speaker 1: if you need two oxen to pull your plow to

46
00:02:32,280 --> 00:02:34,560
Speaker 1: turn the soil in the field where you're growing your

47
00:02:34,600 --> 00:02:37,960
Speaker 1: first crop of alien pod people, you yoke the oxen

48
00:02:38,000 --> 00:02:41,639
Speaker 1: together and they'll pull you together. But in astronomy, yoking

49
00:02:41,760 --> 00:02:45,760
Speaker 1: implies gravitational binding. Of course, we all know the Moon

50
00:02:45,960 --> 00:02:48,880
Speaker 1: is gravitationally bound to the Earth and the Earth is

51
00:02:48,880 --> 00:02:52,360
Speaker 1: gravitationally bound to the Sun. And since the orbits of

52
00:02:52,400 --> 00:02:54,600
Speaker 1: the Earth and the Moon are on pretty close to

53
00:02:54,639 --> 00:02:57,200
Speaker 1: the same plane, but not exactly the same plane, we

54
00:02:57,280 --> 00:03:03,079
Speaker 1: get infrequent solar eclipses across different sections of the Earth's surface.

55
00:03:03,639 --> 00:03:06,600
Speaker 1: And what happens there is pretty straightforward. A total solar

56
00:03:06,639 --> 00:03:10,880
Speaker 1: eclipse occurs when the Moon passes between the Earth and

57
00:03:10,919 --> 00:03:15,240
Speaker 1: the Sun, blocking the Sun's light. Yeah, it just kind

58
00:03:15,280 --> 00:03:17,400
Speaker 1: of it works out just kind of perfectly there, right,

59
00:03:17,480 --> 00:03:21,080
Speaker 1: because the Moon is just the right size to to

60
00:03:21,240 --> 00:03:25,200
Speaker 1: completely block out the Sun as visible from Earth. Yeah,

61
00:03:25,240 --> 00:03:27,720
Speaker 1: and you might wonder why is it such a perfect fit.

62
00:03:27,840 --> 00:03:30,760
Speaker 1: Is there some feature of orbital mechanics that makes it

63
00:03:30,800 --> 00:03:33,760
Speaker 1: that way. No, it's actually a complete coincidence. We just

64
00:03:33,800 --> 00:03:37,720
Speaker 1: got really lucky that our moon is almost exactly the

65
00:03:37,800 --> 00:03:41,280
Speaker 1: same size as our apparent Sun. If Earth's moon were

66
00:03:41,280 --> 00:03:44,120
Speaker 1: smaller in diameter, or if it were farther away from

67
00:03:44,160 --> 00:03:46,680
Speaker 1: the Earth, which it will be further along in Earth's

68
00:03:46,720 --> 00:03:49,360
Speaker 1: history and millions of years, the Moon's going to be

69
00:03:49,480 --> 00:03:52,680
Speaker 1: further out in its orbit, and thus it will it

70
00:03:52,720 --> 00:03:55,360
Speaker 1: will alter the way we have eclipses on Earth's surface.

71
00:03:55,760 --> 00:03:58,440
Speaker 1: But but if the Moon were smaller, if it were

72
00:03:58,480 --> 00:04:01,280
Speaker 1: farther away, it would be apparently smaller than the Sun.

73
00:04:01,600 --> 00:04:04,840
Speaker 1: So instead of covering the Sun completely, it would pass

74
00:04:04,960 --> 00:04:08,800
Speaker 1: across the face of the Sun as a large black dot.

75
00:04:09,120 --> 00:04:12,240
Speaker 1: And you can observe other planets like Venus and Mercury

76
00:04:12,320 --> 00:04:14,840
Speaker 1: already doing this if you have the right kind of telescope.

77
00:04:14,880 --> 00:04:17,880
Speaker 1: For example, if you've never looked up images of the

78
00:04:17,920 --> 00:04:21,000
Speaker 1: transit of Venus, you should check it out. It's really cool.

79
00:04:21,080 --> 00:04:23,480
Speaker 1: You can see that this black dot is the planet

80
00:04:23,560 --> 00:04:27,640
Speaker 1: passes in front of the sun disk. Another way you

81
00:04:27,640 --> 00:04:31,279
Speaker 1: can observe this difference is if you observe moons doing

82
00:04:31,320 --> 00:04:33,400
Speaker 1: this as they line up in sissy g e on

83
00:04:33,480 --> 00:04:36,760
Speaker 1: the surface of other planets. For example, you get the

84
00:04:36,800 --> 00:04:41,240
Speaker 1: Curiosity rover and you turn its camera up so it

85
00:04:41,320 --> 00:04:45,360
Speaker 1: looks towards the Sun. You can observe solar eclipses on

86
00:04:45,520 --> 00:04:49,560
Speaker 1: Mars as the Martian moon Phobos passes in front of

87
00:04:49,600 --> 00:04:52,719
Speaker 1: the Sun. Except it's not really a total eclipse, and

88
00:04:52,760 --> 00:04:56,119
Speaker 1: it never could be because even when Phobos passes dead

89
00:04:56,200 --> 00:04:59,320
Speaker 1: center across the Sun, it's too small to cover up

90
00:04:59,360 --> 00:05:02,120
Speaker 1: the Sun. So in said, it's like a big black

91
00:05:02,240 --> 00:05:04,680
Speaker 1: pupil in the middle of the Sun. As an eye,

92
00:05:04,760 --> 00:05:08,120
Speaker 1: it looks like a big Google eye. I've seen it

93
00:05:08,160 --> 00:05:09,680
Speaker 1: does look like a big Google eye. It's like one

94
00:05:09,720 --> 00:05:11,920
Speaker 1: of those things that did you ever like make those

95
00:05:12,000 --> 00:05:14,200
Speaker 1: little Google eyed toys when you were a kid. You

96
00:05:14,200 --> 00:05:16,280
Speaker 1: can buy old Google eyes at the When I was

97
00:05:16,360 --> 00:05:20,320
Speaker 1: a kid, I've I've never stopped making. For a while,

98
00:05:20,600 --> 00:05:23,359
Speaker 1: I was daring enough to carry around a pack of

99
00:05:23,400 --> 00:05:26,840
Speaker 1: Google eyes and stick them to various signs on our

100
00:05:26,920 --> 00:05:30,560
Speaker 1: local transportation uh, this public transportation system here in Atlanta.

101
00:05:30,640 --> 00:05:32,600
Speaker 1: But but then I got a little scared and stop

102
00:05:32,680 --> 00:05:34,599
Speaker 1: doing it. Why do you get scared and I was

103
00:05:34,640 --> 00:05:36,919
Speaker 1: just a friend like this, I just decided this is

104
00:05:36,920 --> 00:05:39,320
Speaker 1: a silly thing to get in legal trouble for like

105
00:05:39,680 --> 00:05:42,159
Speaker 1: I would hate to be the guy who's arrested for

106
00:05:42,200 --> 00:05:46,080
Speaker 1: putting Google eyes on a on an advertisement, Like is

107
00:05:46,120 --> 00:05:48,839
Speaker 1: this worth the hilarity? And it it was. It was

108
00:05:48,880 --> 00:05:51,240
Speaker 1: a tough decision, but I ultimately decided it was not.

109
00:05:51,520 --> 00:05:54,599
Speaker 1: You know the name of Phobos, the Martian moon, Phobos

110
00:05:54,640 --> 00:05:57,080
Speaker 1: means fear, but it apparently is not afraid of the

111
00:05:57,120 --> 00:06:00,800
Speaker 1: same thing you were becauause up Google eyes the periodically

112
00:06:00,920 --> 00:06:03,760
Speaker 1: make a Google I right on its parent star. Now,

113
00:06:04,279 --> 00:06:08,160
Speaker 1: if you know the right equations to calculate angular diameter

114
00:06:08,279 --> 00:06:11,240
Speaker 1: by distance, that's by saying, okay, if I know how

115
00:06:11,240 --> 00:06:13,919
Speaker 1: big something is and how far away it is, I

116
00:06:13,920 --> 00:06:16,520
Speaker 1: can calculate how many degrees of my view it's going

117
00:06:16,560 --> 00:06:18,960
Speaker 1: to take up. Or if you just have a handy

118
00:06:19,000 --> 00:06:21,560
Speaker 1: online calculator that does this and I came across a

119
00:06:21,600 --> 00:06:24,400
Speaker 1: few you can actually go back and resolve this to

120
00:06:24,440 --> 00:06:26,600
Speaker 1: find out how much of your field of view. Various

121
00:06:26,600 --> 00:06:30,760
Speaker 1: planetary objects will take up at different distances. For example,

122
00:06:30,800 --> 00:06:33,240
Speaker 1: the average distance from the Earth to the Sun is

123
00:06:33,240 --> 00:06:36,560
Speaker 1: about a hundred and fifty million kilometers, and the diameter

124
00:06:36,720 --> 00:06:39,800
Speaker 1: of the Sun is about one point four million kilometers.

125
00:06:40,080 --> 00:06:42,479
Speaker 1: It works out too that the Sun takes up about

126
00:06:42,560 --> 00:06:46,560
Speaker 1: zero point five three degrees of view. Meanwhile, the average

127
00:06:46,600 --> 00:06:48,720
Speaker 1: distance from the Earth to the Moon is about three

128
00:06:48,920 --> 00:06:52,120
Speaker 1: d and eight four thousand, four hundred kilometers, and the

129
00:06:52,160 --> 00:06:55,960
Speaker 1: average diameter and not the average, the equatorial diameter of

130
00:06:56,000 --> 00:06:59,680
Speaker 1: the Moon is three thousand, four hundred and seventy six kilometers.

131
00:07:00,000 --> 00:07:02,440
Speaker 1: If you calculate that, it also takes up just a

132
00:07:02,480 --> 00:07:05,200
Speaker 1: little over half of a degree of view, about zero

133
00:07:05,240 --> 00:07:08,080
Speaker 1: point five one eight and so on. Average both are

134
00:07:08,120 --> 00:07:11,000
Speaker 1: about half a degree, and since degrees are usually broken

135
00:07:11,000 --> 00:07:13,280
Speaker 1: down into units of sixty, argument, it's both are just

136
00:07:13,440 --> 00:07:16,640
Speaker 1: over thirty arc minutes in the sky, so they can

137
00:07:16,720 --> 00:07:19,880
Speaker 1: line up so that the Moon just perfectly blocks out

138
00:07:19,880 --> 00:07:22,600
Speaker 1: the Sun. It's a beautiful fact about Earth that makes

139
00:07:22,680 --> 00:07:26,240
Speaker 1: us special. Now here's the question, Joe, that I imagine

140
00:07:26,280 --> 00:07:29,360
Speaker 1: a number of people have have pondered, is uh, like

141
00:07:29,560 --> 00:07:33,480
Speaker 1: the rarity of a solar eclipse? Because like for me,

142
00:07:33,600 --> 00:07:38,080
Speaker 1: I have never witnessed a total solar eclipse, and therefore

143
00:07:38,160 --> 00:07:39,800
Speaker 1: I'm very excited, like this is the first time in

144
00:07:39,840 --> 00:07:42,040
Speaker 1: my life it'll be the first time in my my

145
00:07:42,120 --> 00:07:45,880
Speaker 1: son's young life. And you know, I'm not sure when

146
00:07:45,880 --> 00:07:49,120
Speaker 1: my next opportunity will will truly come, so I'm gonna

147
00:07:49,240 --> 00:07:51,480
Speaker 1: pounce on it. But but why is it so rare

148
00:07:51,560 --> 00:07:55,120
Speaker 1: if it's just tied up with the very predictable movements

149
00:07:55,320 --> 00:07:58,520
Speaker 1: of of our celestial bodies. Yeah, this is an interesting question.

150
00:07:58,560 --> 00:08:01,520
Speaker 1: So if the Earth orbits the Sun onneon and the

151
00:08:01,560 --> 00:08:04,920
Speaker 1: Moon makes a full orbit around the Earth roughly once

152
00:08:04,960 --> 00:08:08,240
Speaker 1: a month, how come there is not a solar eclipse

153
00:08:08,480 --> 00:08:11,720
Speaker 1: every single month? Think about it, right, So, if it's

154
00:08:11,720 --> 00:08:14,480
Speaker 1: going around the Earth once a month, shouldn't it pass

155
00:08:14,560 --> 00:08:18,120
Speaker 1: directly between the Earth and the Sun once a month. Well,

156
00:08:18,160 --> 00:08:21,600
Speaker 1: it actually does this from one direction, but it doesn't

157
00:08:21,640 --> 00:08:24,800
Speaker 1: from the other direction. So the reason this doesn't happen

158
00:08:24,840 --> 00:08:26,960
Speaker 1: every month is that the orbit of the Moon is

159
00:08:27,000 --> 00:08:31,240
Speaker 1: not exactly flat with respect to Earth's orbit around the Sun.

160
00:08:31,280 --> 00:08:33,560
Speaker 1: And we can call Earth's orbit around the Sun the

161
00:08:33,640 --> 00:08:35,960
Speaker 1: solar plane. Think of that is taking place on a

162
00:08:35,960 --> 00:08:39,319
Speaker 1: flat table. Now, if you're looking top down on this

163
00:08:39,400 --> 00:08:41,640
Speaker 1: flat table at the Earth and the Sun, the Moon

164
00:08:41,760 --> 00:08:45,040
Speaker 1: goes in an oval shaped elliptical orbit around the Earth.

165
00:08:45,280 --> 00:08:47,480
Speaker 1: But if you get down and look across that table

166
00:08:47,520 --> 00:08:49,800
Speaker 1: across the plane. So that the Earth's orbit around the

167
00:08:49,800 --> 00:08:53,000
Speaker 1: Sun is flat, the Moon's orbit around the Earth is

168
00:08:53,040 --> 00:08:56,640
Speaker 1: going to be slightly tipped to the side, tilted just

169
00:08:56,720 --> 00:08:59,319
Speaker 1: about five degrees off. So think of it like a

170
00:08:59,360 --> 00:09:03,400
Speaker 1: wide brim hat, just slightly cocked to the side. And

171
00:09:03,440 --> 00:09:06,000
Speaker 1: so what that means is most of the time, the

172
00:09:06,000 --> 00:09:09,760
Speaker 1: Moon is not directly on that flat plane between the

173
00:09:09,800 --> 00:09:13,600
Speaker 1: Earth and the Sun and just intersects that plane twice

174
00:09:13,640 --> 00:09:16,920
Speaker 1: every month, once going up and once coming down north

175
00:09:16,960 --> 00:09:20,040
Speaker 1: to south ooh, and south to north. So the only

176
00:09:20,080 --> 00:09:22,440
Speaker 1: time you get a solar eclipse is when these two

177
00:09:22,480 --> 00:09:27,360
Speaker 1: intersections happen at the same time, you know, by coincidence.

178
00:09:27,600 --> 00:09:30,280
Speaker 1: So when the Moon passes between the Earth and the

179
00:09:30,320 --> 00:09:34,080
Speaker 1: Sun on the east west axis and when it just

180
00:09:34,200 --> 00:09:38,679
Speaker 1: happens to be simultaneously crossing the solar plane across the

181
00:09:38,720 --> 00:09:42,000
Speaker 1: north south axis, that's when you get a solar eclipse.

182
00:09:43,080 --> 00:09:46,800
Speaker 1: Now that being said, obviously every solar eclipse is not

183
00:09:46,920 --> 00:09:50,440
Speaker 1: a total solar eclipse. We have a few different varieties here, right,

184
00:09:50,480 --> 00:09:52,840
Speaker 1: So you've got the partial solar eclipse. This is the

185
00:09:52,880 --> 00:09:56,320
Speaker 1: pac Man eclipse. Uh, the Moon partially blocks out the

186
00:09:56,320 --> 00:09:58,720
Speaker 1: Sun it'll some people would say it takes a bite

187
00:09:58,720 --> 00:10:00,360
Speaker 1: out of the Sun and giving it a press and

188
00:10:00,440 --> 00:10:04,800
Speaker 1: appearance and a brief, sometimes undetectable dip and luminosity depending

189
00:10:04,800 --> 00:10:06,480
Speaker 1: on how much of it, how much of the Moon

190
00:10:06,880 --> 00:10:09,800
Speaker 1: is crossing the Sun, based on your vantage point. And

191
00:10:09,800 --> 00:10:12,720
Speaker 1: in this type of eclipse, the Moon never completely blocks

192
00:10:12,720 --> 00:10:15,560
Speaker 1: out the Sun. So these happen fairly often and they're

193
00:10:15,600 --> 00:10:18,600
Speaker 1: not as startling or as you know, attention getting as

194
00:10:18,640 --> 00:10:22,240
Speaker 1: a total solar eclipse. A total solar eclipse is when

195
00:10:22,280 --> 00:10:25,880
Speaker 1: the Moon completely blocks out the Sun, causing darkness at

196
00:10:25,960 --> 00:10:28,360
Speaker 1: day and the ability to look up at the sun

197
00:10:28,480 --> 00:10:32,280
Speaker 1: disk blocked with the naked eye and see the corona

198
00:10:32,360 --> 00:10:35,360
Speaker 1: around the Sun. Now, I want to modify naked eye

199
00:10:35,360 --> 00:10:38,240
Speaker 1: in a minute, because there are some important precautions you'll

200
00:10:38,240 --> 00:10:40,120
Speaker 1: need to take if you're going to be viewing the

201
00:10:40,160 --> 00:10:42,240
Speaker 1: solar eclipse this year. Now, I do want to throw

202
00:10:42,280 --> 00:10:44,640
Speaker 1: in real quick, we're not really talking about lunar eclipses

203
00:10:45,000 --> 00:10:48,840
Speaker 1: in this episode. But what's occurring there is you're seeing

204
00:10:49,000 --> 00:10:52,480
Speaker 1: um that the shadow of the Earth cast upon the Moon, right,

205
00:10:52,520 --> 00:10:55,040
Speaker 1: So it's going to be the opposite side effect of

206
00:10:55,080 --> 00:10:57,600
Speaker 1: the solar eclipse. It's when the Moon happens to be

207
00:10:57,679 --> 00:11:01,040
Speaker 1: crossing the solar plane at the same time that it's

208
00:11:01,080 --> 00:11:04,960
Speaker 1: directly behind the Earth on the east west axis. Alright,

209
00:11:05,000 --> 00:11:07,920
Speaker 1: so solar eclipse that we have partial, we have total.

210
00:11:08,080 --> 00:11:10,800
Speaker 1: What else do we have. We've also got the annular eclipse,

211
00:11:10,800 --> 00:11:12,880
Speaker 1: and this one is kind of interesting. So this is

212
00:11:12,920 --> 00:11:15,960
Speaker 1: when you would have a total eclipse. It's when the

213
00:11:16,000 --> 00:11:19,160
Speaker 1: Moon does pass directly in front of the Sun from

214
00:11:19,200 --> 00:11:23,280
Speaker 1: your point of view, but it never completely blocks the Sun. Instead,

215
00:11:23,360 --> 00:11:27,160
Speaker 1: what happens is it leaves an always visible ring of

216
00:11:27,280 --> 00:11:31,000
Speaker 1: sunlight around it. If one of these is happening, you

217
00:11:31,040 --> 00:11:33,679
Speaker 1: should not look at the annular eclipse of the naked

218
00:11:33,679 --> 00:11:35,440
Speaker 1: eye because a lot of the sunlight is still going

219
00:11:35,480 --> 00:11:38,120
Speaker 1: to be getting through. Now you might be thinking, wait

220
00:11:38,120 --> 00:11:40,280
Speaker 1: a minute, how can that happen, because didn't we just

221
00:11:40,360 --> 00:11:43,040
Speaker 1: talk about how from our perspective, the Moon and the

222
00:11:43,040 --> 00:11:46,160
Speaker 1: Sun are the same size. Well, they they're about the

223
00:11:46,200 --> 00:11:50,679
Speaker 1: same size on average, But those averages are just averages.

224
00:11:50,760 --> 00:11:53,560
Speaker 1: So the apparent size of the Sun and the Moon

225
00:11:53,960 --> 00:11:57,200
Speaker 1: can both vary depending on where they are in their orbits.

226
00:11:58,000 --> 00:12:00,080
Speaker 1: In both cases, I was calculating on the base of

227
00:12:00,120 --> 00:12:03,400
Speaker 1: average distances. Uh, and so the Earth and the Moon

228
00:12:03,559 --> 00:12:08,040
Speaker 1: both have elliptical orbits around their their gravitational parents rather

229
00:12:08,080 --> 00:12:11,520
Speaker 1: than perfectly circular ones. When the Moon is closest to

230
00:12:11,559 --> 00:12:15,320
Speaker 1: the Earth, this is called the parage, it looks bigger,

231
00:12:15,720 --> 00:12:18,079
Speaker 1: and when the Moon is farthest from the Earth, of course,

232
00:12:18,080 --> 00:12:20,880
Speaker 1: this is called the apoge it looks smaller. Likewise, there's

233
00:12:20,920 --> 00:12:24,280
Speaker 1: a tiny amount of variation in how big the Sun looks,

234
00:12:24,280 --> 00:12:27,120
Speaker 1: given whether the Earth is closest in its orbit or

235
00:12:27,160 --> 00:12:30,320
Speaker 1: farther away in its orbit. So if the Moon is

236
00:12:30,360 --> 00:12:33,360
Speaker 1: at a lower apparent diameter and the Sun's at a

237
00:12:33,400 --> 00:12:37,199
Speaker 1: greater apparent diameter, the Moon could fall directly in the

238
00:12:37,240 --> 00:12:40,040
Speaker 1: middle of the Sun and still not block the whole thing.

239
00:12:40,160 --> 00:12:42,040
Speaker 1: So you get a ring of light in the sky,

240
00:12:42,440 --> 00:12:45,840
Speaker 1: and this is what's known as the annular eclipse. There's

241
00:12:45,880 --> 00:12:48,640
Speaker 1: also another rare type of eclipse called the hybrid eclipse,

242
00:12:48,679 --> 00:12:51,760
Speaker 1: and this this happens when the apparent diameters of the

243
00:12:51,800 --> 00:12:53,480
Speaker 1: Sun and the Moon are sort of right on the

244
00:12:53,520 --> 00:12:56,959
Speaker 1: boundary of going from annular to total. So some people

245
00:12:57,000 --> 00:12:59,600
Speaker 1: on the Earth will see an annular eclipse, and people

246
00:12:59,640 --> 00:13:02,440
Speaker 1: in other locations we'll see a total solar eclipse. And

247
00:13:02,440 --> 00:13:04,440
Speaker 1: this is when we have werewolves, right, because there, of

248
00:13:04,440 --> 00:13:07,320
Speaker 1: course the hybrid of man and wolf. I mean, when

249
00:13:07,320 --> 00:13:10,600
Speaker 1: else would we have werewolves. It's the prime opportunity. It's

250
00:13:10,640 --> 00:13:13,560
Speaker 1: important that you point out that the solar eclipse has

251
00:13:13,640 --> 00:13:16,800
Speaker 1: these kind of supernatural connotations. We we talked in our

252
00:13:16,840 --> 00:13:20,080
Speaker 1: other eclipse episode about many of the myths associated with eclipses,

253
00:13:20,320 --> 00:13:23,880
Speaker 1: but there are particular myths associated with the total solar eclipses, right.

254
00:13:24,280 --> 00:13:26,800
Speaker 1: Oh yeah, I mean it makes sense right that you

255
00:13:26,800 --> 00:13:30,240
Speaker 1: have this this cosmic event. You know, early early people

256
00:13:30,240 --> 00:13:33,320
Speaker 1: are looking up into the uh at the stars, at

257
00:13:33,360 --> 00:13:35,360
Speaker 1: the sun and the moon and trying to make sense

258
00:13:35,400 --> 00:13:39,360
Speaker 1: of what's occurring there. They have myths that are that

259
00:13:39,480 --> 00:13:42,359
Speaker 1: in some cases have been created to explain natural phenomena,

260
00:13:42,559 --> 00:13:44,800
Speaker 1: but in other cases, you know, kind of exist on

261
00:13:44,840 --> 00:13:48,640
Speaker 1: their own but then get reinterpreted in the light of

262
00:13:48,760 --> 00:13:51,360
Speaker 1: natural phenomena. We've talked about this sort of interplay and

263
00:13:51,520 --> 00:13:56,000
Speaker 1: varying theories of of of natural phenomena and mythology before.

264
00:13:57,160 --> 00:13:59,079
Speaker 1: But the result is, yeah, you have a number of

265
00:14:00,280 --> 00:14:04,880
Speaker 1: a number of monsters and monstrous creatures that are said

266
00:14:04,960 --> 00:14:08,160
Speaker 1: to eat the sun or the moon, or attempt to

267
00:14:08,200 --> 00:14:10,959
Speaker 1: eat the sun or the moon. Uh. For instance, in

268
00:14:11,000 --> 00:14:15,840
Speaker 1: the case of the the Indian UH entity Raju Uh,

269
00:14:15,880 --> 00:14:18,560
Speaker 1: he's this decapitated head and it has said that he

270
00:14:18,600 --> 00:14:20,720
Speaker 1: eats the sun, but then the sun falls back out

271
00:14:20,720 --> 00:14:23,320
Speaker 1: of his next jump because he has has no body.

272
00:14:23,640 --> 00:14:26,280
Speaker 1: And we talk about that myth in detail in our

273
00:14:26,320 --> 00:14:28,440
Speaker 1: our Past eclipse episode, which will be linked to on

274
00:14:28,480 --> 00:14:30,280
Speaker 1: the landing page for this episode is stuff to blow

275
00:14:30,320 --> 00:14:32,840
Speaker 1: your mind dot com. That is such a visceral and

276
00:14:32,960 --> 00:14:35,880
Speaker 1: wonderful myth. It's like it's like something you'd see in

277
00:14:35,880 --> 00:14:38,680
Speaker 1: an itchy and scratchy cartoon. Yes, I don't mean to denigrated.

278
00:14:38,760 --> 00:14:42,000
Speaker 1: I mean it's just like so it's so gory. Oh yeah.

279
00:14:42,000 --> 00:14:43,440
Speaker 1: And I didn't even get into the details of the

280
00:14:43,520 --> 00:14:48,480
Speaker 1: decapitation where he's decapitated with this divine weapon that's kind

281
00:14:48,480 --> 00:14:51,800
Speaker 1: of like the spinning weapon and crawl. So it's it's

282
00:14:51,840 --> 00:14:54,240
Speaker 1: it's a pretty delightful episode. It's one of my favorite

283
00:14:54,400 --> 00:14:58,320
Speaker 1: UH eclipse myths for sure. Well, it's not a surprise

284
00:14:58,480 --> 00:15:01,960
Speaker 1: that the eclipse call as people to think of the supernatural,

285
00:15:02,000 --> 00:15:05,040
Speaker 1: because it's one of the most awe inspiring sites in nature.

286
00:15:05,080 --> 00:15:08,200
Speaker 1: It's hard to think of something that without the aid

287
00:15:08,240 --> 00:15:12,800
Speaker 1: of technology, humans can see that is so unbelievable and

288
00:15:12,880 --> 00:15:15,400
Speaker 1: so alien to our day to day experience. And we're

289
00:15:15,400 --> 00:15:18,880
Speaker 1: talking about the sun going dark. Uh it this is

290
00:15:18,920 --> 00:15:20,880
Speaker 1: the kind of thing that ties into at least two

291
00:15:20,880 --> 00:15:25,160
Speaker 1: different apocalypse smiths, both the Christian Apocalypse as well as

292
00:15:25,640 --> 00:15:29,480
Speaker 1: North Ragnarok. Yeah, it seems like a literal challenge to

293
00:15:29,560 --> 00:15:33,440
Speaker 1: the established order of the cosmos night and day light

294
00:15:33,520 --> 00:15:37,080
Speaker 1: and dark sun in the moon. It's completely destabilizing. So

295
00:15:37,120 --> 00:15:39,520
Speaker 1: it's just no wonder that many people throughout history have

296
00:15:39,640 --> 00:15:43,120
Speaker 1: reacted to it with sheer terror. Now, apart from the

297
00:15:43,160 --> 00:15:45,720
Speaker 1: traffic that you may expect, we hope you will not

298
00:15:45,840 --> 00:15:48,680
Speaker 1: react to this eclipse with sheer terror, but with all

299
00:15:48,720 --> 00:15:52,600
Speaker 1: the wonder that's due to this fantastic demonstration of physics

300
00:15:52,600 --> 00:15:55,720
Speaker 1: and nature at work. So maybe when we come back

301
00:15:55,760 --> 00:15:58,520
Speaker 1: from a quick break, we will talk about this upcoming

302
00:15:58,560 --> 00:16:06,960
Speaker 1: eclipse in August of only seventeen. All right, we're back. So, Joe,

303
00:16:06,960 --> 00:16:08,960
Speaker 1: I don't know do you have plans yet for the eclipse.

304
00:16:09,120 --> 00:16:11,680
Speaker 1: I'm still trying to make up my mind about what

305
00:16:11,720 --> 00:16:16,080
Speaker 1: I'm gonna do. I've got several options, and I'm I'm

306
00:16:16,240 --> 00:16:19,520
Speaker 1: so disclosure here. Robert and I we live in Atlanta here,

307
00:16:19,600 --> 00:16:23,760
Speaker 1: so we're pretty close to the line of totality, and

308
00:16:23,840 --> 00:16:26,840
Speaker 1: so Robert, I know you have some plans. Yeah, the

309
00:16:26,880 --> 00:16:29,000
Speaker 1: family and I are going to drive up to the

310
00:16:29,040 --> 00:16:33,840
Speaker 1: mountains and uh and seek the total eclipse. Nice. So

311
00:16:34,000 --> 00:16:36,800
Speaker 1: if you live almost anywhere in the United States, you

312
00:16:36,880 --> 00:16:40,040
Speaker 1: will be able to see a partial solar eclipse, which

313
00:16:40,120 --> 00:16:43,040
Speaker 1: is the Moon's shadow passing over part of the Sun.

314
00:16:44,040 --> 00:16:46,840
Speaker 1: But there are other chances that people are going to

315
00:16:46,920 --> 00:16:49,920
Speaker 1: have to see that. Impartial solar eclipses are much easier

316
00:16:49,960 --> 00:16:52,760
Speaker 1: to see because they just affect a much larger portion

317
00:16:52,840 --> 00:16:55,880
Speaker 1: of the Earth's surface. If you were within what's called

318
00:16:56,000 --> 00:16:59,200
Speaker 1: the line of totality, you will get to see a

319
00:16:59,240 --> 00:17:04,040
Speaker 1: total soul eclipse on Monday, August one, and that's the

320
00:17:04,080 --> 00:17:07,520
Speaker 1: Moon passing straight in front of the Sun and completely

321
00:17:07,560 --> 00:17:10,680
Speaker 1: blocking it out. So the line of totality is about

322
00:17:10,760 --> 00:17:14,000
Speaker 1: seventy miles or about a hundred and ten kilometers wide.

323
00:17:14,400 --> 00:17:17,359
Speaker 1: If you're within that line, that's where the total solar

324
00:17:17,400 --> 00:17:20,600
Speaker 1: eclipse will happen. And the total eclipse will start in

325
00:17:20,760 --> 00:17:24,480
Speaker 1: northern central Oregon um at about ten fifteen am. I

326
00:17:24,480 --> 00:17:27,400
Speaker 1: think they say first contact, which is when the sun

327
00:17:27,560 --> 00:17:31,040
Speaker 1: very first touches the Moon. That's going to happen sometime

328
00:17:31,040 --> 00:17:34,560
Speaker 1: closer to nine am Pacific time over there, but first

329
00:17:34,600 --> 00:17:37,680
Speaker 1: will happen about ten fifteen am Pacific time, and it's

330
00:17:37,680 --> 00:17:40,159
Speaker 1: slowly going to pass over the United States, and a

331
00:17:40,240 --> 00:17:47,960
Speaker 1: line running southeast from Oregon through Idaho, Wyoming, Nebraska, Missouri, Kentucky, Tennessee, Georgia,

332
00:17:48,000 --> 00:17:50,960
Speaker 1: and South Carolina, also touching small parts of a few

333
00:17:50,960 --> 00:17:53,280
Speaker 1: other states. You can look up a map online. There

334
00:17:53,280 --> 00:17:55,879
Speaker 1: are a bunch of them. NASA has done one all right. Now,

335
00:17:55,880 --> 00:17:59,000
Speaker 1: we've already talked about the rarity of solar eclipse, but

336
00:17:59,080 --> 00:18:02,440
Speaker 1: just just how rare are they really? Well, there's sort

337
00:18:02,480 --> 00:18:06,160
Speaker 1: of a misconception actually that solar eclipses are extremely rare

338
00:18:06,400 --> 00:18:10,840
Speaker 1: on principle, and actually solar eclipses and lunar eclipses happen

339
00:18:10,920 --> 00:18:13,360
Speaker 1: it pretty close to the same rate, if I think,

340
00:18:13,400 --> 00:18:16,359
Speaker 1: if you count pennumber lunar eclipses, lunar eclipses are a

341
00:18:16,359 --> 00:18:20,480
Speaker 1: little bit more common. According to the Belgian astronomers gen Mayas,

342
00:18:20,480 --> 00:18:23,160
Speaker 1: in the twentieth century, there were two hundred and twenty

343
00:18:23,200 --> 00:18:26,280
Speaker 1: eight solar eclipses and two d and twenty nine lunar eclipses,

344
00:18:26,480 --> 00:18:30,720
Speaker 1: So they're not actually a rare phenomenon in themselves. But

345
00:18:30,800 --> 00:18:34,200
Speaker 1: what's rare is for a total solar eclipse to pass

346
00:18:34,280 --> 00:18:38,280
Speaker 1: over wherever you happen to be. So, as as we

347
00:18:38,320 --> 00:18:41,359
Speaker 1: discussed a minute ago, not all solar eclipses are total eclipses.

348
00:18:41,359 --> 00:18:44,600
Speaker 1: Some are partial or annular. And solar eclipses happen all

349
00:18:44,600 --> 00:18:47,320
Speaker 1: the time, but you probably won't get many chances in

350
00:18:47,320 --> 00:18:50,080
Speaker 1: your life to see one unless you have the resources

351
00:18:50,119 --> 00:18:53,000
Speaker 1: to travel around the globe and chase these lines of

352
00:18:53,040 --> 00:18:57,359
Speaker 1: totality wherever they happen to be falling. All right, so

353
00:18:57,680 --> 00:19:00,560
Speaker 1: let's get let's get down to brass tacks here. Okay,

354
00:19:01,080 --> 00:19:03,600
Speaker 1: driving up to uh, you know, the line of totality

355
00:19:03,680 --> 00:19:06,240
Speaker 1: is one thing, right, you know, maybe you're close to it,

356
00:19:06,280 --> 00:19:08,680
Speaker 1: maybe you're far away, but with enough planning you can

357
00:19:08,720 --> 00:19:11,840
Speaker 1: get there staring at the sun the whole way. Because

358
00:19:11,880 --> 00:19:15,119
Speaker 1: that's the thing that what does one need to protect

359
00:19:15,359 --> 00:19:19,240
Speaker 1: themselves while staring at the sign, while staring up even

360
00:19:19,240 --> 00:19:22,480
Speaker 1: at a sun that is about to be obscured, uh

361
00:19:22,520 --> 00:19:25,520
Speaker 1: by the moon. Uh? You know what, we have all

362
00:19:25,560 --> 00:19:28,000
Speaker 1: these special glasses that are suddenly on the market. I mean,

363
00:19:28,160 --> 00:19:31,080
Speaker 1: you can even buy them. I saw them at lows. Uh,

364
00:19:31,200 --> 00:19:33,720
Speaker 1: why are these necessary? I was talking to a good

365
00:19:33,720 --> 00:19:36,320
Speaker 1: friend of ours and and he was like, I mean

366
00:19:36,560 --> 00:19:39,000
Speaker 1: he's he's a cautious dude. But he was like, yeah,

367
00:19:39,000 --> 00:19:40,919
Speaker 1: I think you think you can probably look at the

368
00:19:40,920 --> 00:19:44,119
Speaker 1: eclipse and you'll be all right. Just the same as

369
00:19:44,160 --> 00:19:47,040
Speaker 1: you should never look directly at the sun without proper

370
00:19:47,080 --> 00:19:49,800
Speaker 1: eye protection. You should never look directly at part of

371
00:19:49,840 --> 00:19:52,920
Speaker 1: the sun without proper eye protection. And if you're thinking,

372
00:19:53,640 --> 00:19:57,399
Speaker 1: says you, you know you big buzz kill. Uh maybe

373
00:19:57,400 --> 00:19:59,680
Speaker 1: you think people have been looking at eclipses for thousands

374
00:19:59,720 --> 00:20:03,000
Speaker 1: of years it is, without special goggles. And they were fine, No, really,

375
00:20:03,640 --> 00:20:06,480
Speaker 1: I've been reading about this. Don't look at the sun

376
00:20:06,720 --> 00:20:10,720
Speaker 1: or even part of the sun. Here's what could happen. Uh.

377
00:20:10,760 --> 00:20:13,240
Speaker 1: First of all, there if you want to hear it

378
00:20:13,280 --> 00:20:16,080
Speaker 1: directly from an expert, there's a very quick interview that

379
00:20:16,119 --> 00:20:19,680
Speaker 1: news Week did with Dr Christopher Quinn, who's the president

380
00:20:19,680 --> 00:20:23,240
Speaker 1: of the American Optimetric Association, about what kinds of injuries

381
00:20:23,280 --> 00:20:25,359
Speaker 1: result from looking at the sun without protection. You can

382
00:20:25,359 --> 00:20:27,560
Speaker 1: go check that out if you want, but I'll give

383
00:20:27,600 --> 00:20:33,600
Speaker 1: you the basic rundown. One possibility is photocarrotitis. So photocarrotitis

384
00:20:33,640 --> 00:20:36,920
Speaker 1: is usually described as a sunburn of the eye. It's

385
00:20:36,920 --> 00:20:40,400
Speaker 1: not pleasant sounding at all. Yeah yeah, and you can't

386
00:20:40,400 --> 00:20:43,680
Speaker 1: really rub alo on your eye volcan now. So it's

387
00:20:43,720 --> 00:20:47,919
Speaker 1: when UV radiation ultra violet radiation causes damage to the

388
00:20:48,040 --> 00:20:51,639
Speaker 1: cornea and the conjunctiva, which are the outer surfaces of

389
00:20:51,680 --> 00:20:56,280
Speaker 1: the eyeball, and symptoms include pain, a feeling of having

390
00:20:56,400 --> 00:20:59,920
Speaker 1: grit or another foreign body in the eye. Red eye

391
00:21:00,080 --> 00:21:05,359
Speaker 1: is swelling, sensitivity to light, excessive tearing, and sometimes temporary

392
00:21:05,440 --> 00:21:09,800
Speaker 1: loss of vision. So welding arcs produce UV radiation, and

393
00:21:09,800 --> 00:21:11,720
Speaker 1: this is what can happen to a lot of welders

394
00:21:11,760 --> 00:21:14,479
Speaker 1: if they don't use safety goggles or welding glass when

395
00:21:14,480 --> 00:21:18,680
Speaker 1: they're doing their work. Uh. The photocarrotitis is also sometimes

396
00:21:18,840 --> 00:21:21,240
Speaker 1: referred to as snow blindness. I know you've heard of

397
00:21:21,280 --> 00:21:24,439
Speaker 1: snowboy in this. The reason it's linked to snow is

398
00:21:24,480 --> 00:21:27,160
Speaker 1: that snow covered ground tends to reflect a much greater

399
00:21:27,280 --> 00:21:31,520
Speaker 1: percent of UV radiation than most other natural surfaces like

400
00:21:31,640 --> 00:21:34,760
Speaker 1: grass or soil usually reflect only about ten percent of

401
00:21:34,800 --> 00:21:38,440
Speaker 1: the UV rays coming from above. Snow can reflect almost

402
00:21:38,480 --> 00:21:41,840
Speaker 1: all of it, nearly doubling your UV exposure, So in

403
00:21:41,880 --> 00:21:45,840
Speaker 1: snowy environments it's important to wear eye protection. But hey,

404
00:21:45,960 --> 00:21:48,920
Speaker 1: here we're only talking about the reflected or ambient rays.

405
00:21:49,359 --> 00:21:52,160
Speaker 1: If you're looking at an eclipse, you're looking directly at

406
00:21:52,200 --> 00:21:54,679
Speaker 1: the sun, and if you do that, even for a

407
00:21:54,800 --> 00:21:57,840
Speaker 1: very short time, you are inviting sunburn of the eye.

408
00:21:58,240 --> 00:22:00,520
Speaker 1: So if you think you've got photocarreti is you should

409
00:22:00,520 --> 00:22:02,840
Speaker 1: probably see a doctor. But the good news is this

410
00:22:02,920 --> 00:22:05,160
Speaker 1: will usually heal on its own in a few days

411
00:22:05,640 --> 00:22:07,879
Speaker 1: if you remove the source of injury and give your

412
00:22:07,880 --> 00:22:11,479
Speaker 1: eyes some rest. However, there are other possible injuries that

413
00:22:11,560 --> 00:22:15,639
Speaker 1: are more serious. How about photic retina pathy. I'm not

414
00:22:15,680 --> 00:22:18,040
Speaker 1: sure I've heard of this one. This sounds painful as

415
00:22:18,080 --> 00:22:22,160
Speaker 1: well well. This occurs when exposure to direct intense light,

416
00:22:22,280 --> 00:22:27,520
Speaker 1: such as sunlight, lasers, or welding arc light causes phototoxic

417
00:22:27,680 --> 00:22:30,600
Speaker 1: damage to the retina itself. And this is not going

418
00:22:30,640 --> 00:22:32,560
Speaker 1: to be on the outer layer of the eye. Like

419
00:22:32,800 --> 00:22:37,159
Speaker 1: we mentioned with photocaratitis. The retina is the projector screen

420
00:22:37,200 --> 00:22:39,600
Speaker 1: of the eye. It's the It's the layer of the

421
00:22:39,680 --> 00:22:43,760
Speaker 1: rods and cones, the light sensitive cells that detect incoming

422
00:22:43,800 --> 00:22:47,359
Speaker 1: information and transmit it to the brain, and exposure to

423
00:22:47,400 --> 00:22:50,280
Speaker 1: intense light in these cells can cause injury through two

424
00:22:50,280 --> 00:22:54,200
Speaker 1: main mechanisms. A minor mechanism is going to be thermal burn,

425
00:22:54,520 --> 00:22:57,760
Speaker 1: like heat burn burn through the heating of tissue. And

426
00:22:57,800 --> 00:22:59,960
Speaker 1: this generally only happens when you're looking at the sun

427
00:23:00,119 --> 00:23:03,320
Speaker 1: through a telescope or a magnifying lens of some kind

428
00:23:03,440 --> 00:23:06,720
Speaker 1: that concentrates the radiation, sort of like you know, you

429
00:23:06,760 --> 00:23:09,480
Speaker 1: knew the kid who burned dance with a magnifying glass,

430
00:23:09,480 --> 00:23:14,080
Speaker 1: except the answer your own eyes. So we're talking about it, uh,

431
00:23:14,240 --> 00:23:16,560
Speaker 1: in our first case, we're talking about outer eye damage.

432
00:23:16,640 --> 00:23:18,879
Speaker 1: Now we're talking about inner eye damage, right, But that

433
00:23:18,880 --> 00:23:22,719
Speaker 1: that's the minor cause. The major cause of photic retina

434
00:23:22,760 --> 00:23:27,120
Speaker 1: pathy would actually be photochemical toxicity, and this happens when

435
00:23:27,160 --> 00:23:31,360
Speaker 1: exposure to excess light causes chemical reactions in the retinal

436
00:23:31,480 --> 00:23:35,080
Speaker 1: receptor cells that damage the retina and reduce its ability

437
00:23:35,160 --> 00:23:38,639
Speaker 1: to detect a light. This damage can be permanent or temporary,

438
00:23:38,760 --> 00:23:41,800
Speaker 1: It just depends on the case. So you might be

439
00:23:41,840 --> 00:23:44,399
Speaker 1: wondering how often does this kind of thing happen to

440
00:23:44,520 --> 00:23:49,560
Speaker 1: eclipse viewers. A report in the British Medical Journal assess

441
00:23:49,600 --> 00:23:51,920
Speaker 1: the aftermath of a recent solar eclipse that was just

442
00:23:52,080 --> 00:23:54,680
Speaker 1: visible in the UK, and so the author seemed to

443
00:23:54,720 --> 00:23:58,199
Speaker 1: think that the campaign of public safety warnings ahead of

444
00:23:58,200 --> 00:24:02,120
Speaker 1: the eclipse mostly succeeded in preventing people from looking at

445
00:24:02,119 --> 00:24:05,040
Speaker 1: it with the naked eye. About a week after the eclipse,

446
00:24:05,040 --> 00:24:08,439
Speaker 1: he could find fourteen reported cases of retinal injury in

447
00:24:08,440 --> 00:24:12,760
Speaker 1: British hospitals. Many more people called emergency helplines are presented

448
00:24:12,760 --> 00:24:16,080
Speaker 1: at hospitals with fear of injury, but most were false alarms.

449
00:24:16,320 --> 00:24:19,720
Speaker 1: And I got to read one quote quote one overseas

450
00:24:19,720 --> 00:24:23,240
Speaker 1: tourists who sought help in Glasgow said that she was

451
00:24:23,280 --> 00:24:27,200
Speaker 1: worried because she had not been exposed to the Scottish before.

452
00:24:28,520 --> 00:24:31,920
Speaker 1: Another Glasgow patient was concerned that her face had been

453
00:24:31,960 --> 00:24:34,879
Speaker 1: turned yellow by the eclipse, but was told that her

454
00:24:34,960 --> 00:24:39,280
Speaker 1: longstanding liver problem was the culprit. Oh man, let's get

455
00:24:39,920 --> 00:24:44,479
Speaker 1: both of those cases are interesting insights into the like

456
00:24:44,520 --> 00:24:50,440
Speaker 1: the self analyzing, self diagnosing a tendencies that we have. Right, So,

457
00:24:50,520 --> 00:24:53,919
Speaker 1: not that many people had permanent eye damage, but he's

458
00:24:53,960 --> 00:24:56,000
Speaker 1: attributing that to the fact that they had had a

459
00:24:56,040 --> 00:25:00,280
Speaker 1: massive public information campaign saying don't look at this thing

460
00:25:00,359 --> 00:25:04,320
Speaker 1: without eye protection. So and eye protection, by the way,

461
00:25:04,560 --> 00:25:08,960
Speaker 1: does not mean sunglasses. This is crucial. Now before we

462
00:25:09,000 --> 00:25:12,000
Speaker 1: get into health safety information, we do have to do

463
00:25:12,119 --> 00:25:15,800
Speaker 1: the disclaimer right. We are not optimologists or any other

464
00:25:15,840 --> 00:25:18,560
Speaker 1: kind of physicians or I safety experts. Will do our

465
00:25:18,600 --> 00:25:21,359
Speaker 1: best to brief you on eclipse viewing safety, but you

466
00:25:21,400 --> 00:25:25,600
Speaker 1: should check with other sources, including the American Astronomical Society,

467
00:25:25,720 --> 00:25:30,200
Speaker 1: NASA and the American Academy of Ophthalmology and other experts

468
00:25:30,240 --> 00:25:32,439
Speaker 1: of course, And if you interpret anything we say to

469
00:25:32,480 --> 00:25:36,600
Speaker 1: be in conflict with what they say, obviously go with them. Also,

470
00:25:36,680 --> 00:25:40,760
Speaker 1: if there's any ambiguity about when and under what circumstances

471
00:25:40,800 --> 00:25:43,240
Speaker 1: you can or should look at the sun, just don't

472
00:25:43,240 --> 00:25:47,040
Speaker 1: look at the sun. So here's the rundown. If you

473
00:25:47,080 --> 00:25:49,359
Speaker 1: are within the line of totality where the Sun is

474
00:25:49,400 --> 00:25:52,600
Speaker 1: completely blocked out by the Moon, it is safe to

475
00:25:52,640 --> 00:25:55,440
Speaker 1: look at the eclipse with the naked eye, but only

476
00:25:55,600 --> 00:25:59,080
Speaker 1: for the brief time when the Sun is completely blocked

477
00:25:59,560 --> 00:26:01,560
Speaker 1: and this is only gonna last a couple of minutes

478
00:26:01,680 --> 00:26:04,119
Speaker 1: or so, depending on where you are along the line.

479
00:26:04,600 --> 00:26:07,359
Speaker 1: If you are not directly within the line of totality,

480
00:26:07,400 --> 00:26:10,480
Speaker 1: if you're in one of those partial eclipse areas, or

481
00:26:10,600 --> 00:26:12,879
Speaker 1: if you want to look directly at the eclipse during

482
00:26:12,880 --> 00:26:16,160
Speaker 1: its partial phases, while the Moon is covering up the Sun,

483
00:26:16,400 --> 00:26:19,440
Speaker 1: or while the Moon is moving away from the Sun. Uh,

484
00:26:19,480 --> 00:26:22,080
Speaker 1: anytime the disc is partially covered, you need to look

485
00:26:22,119 --> 00:26:27,080
Speaker 1: through a verified safety filter. Regular sunglasses are no good

486
00:26:27,240 --> 00:26:30,879
Speaker 1: and not safe. NASA has actually issued guidelines on what

487
00:26:31,040 --> 00:26:33,640
Speaker 1: is safe. So you've got a few options here. One

488
00:26:33,760 --> 00:26:36,240
Speaker 1: is what you mentioned, Robert, eclipse glasses, right, do you

489
00:26:36,240 --> 00:26:40,160
Speaker 1: already have yours? We have ordered them. Okay, you've got

490
00:26:40,160 --> 00:26:43,880
Speaker 1: to get eclipse glasses from a reputable manufacturer. These look

491
00:26:44,000 --> 00:26:46,439
Speaker 1: like regular three D glasses sort of there like a

492
00:26:46,480 --> 00:26:51,120
Speaker 1: cardboard frame with a partially reflective surface over the lenses.

493
00:26:51,440 --> 00:26:53,239
Speaker 1: If you have these, one way you can test them

494
00:26:53,240 --> 00:26:55,440
Speaker 1: out and make sure they're legit is just put them

495
00:26:55,480 --> 00:26:57,840
Speaker 1: on without looking at the sun or anything, and just

496
00:26:57,880 --> 00:27:00,240
Speaker 1: look around. You shouldn't be able to see any thing.

497
00:27:00,720 --> 00:27:04,240
Speaker 1: Should be completely opaque pretty much. But if you look

498
00:27:04,280 --> 00:27:06,480
Speaker 1: up at the sun, you you'll be able to see that,

499
00:27:06,520 --> 00:27:08,920
Speaker 1: but pretty much anything else is going to be blocked out.

500
00:27:09,720 --> 00:27:12,040
Speaker 1: But anyway, you should make sure you get your eclipse

501
00:27:12,040 --> 00:27:14,800
Speaker 1: glasses from a reputable vendor who is not trying to

502
00:27:14,840 --> 00:27:17,400
Speaker 1: sell you actual three D glasses. They're going to burn

503
00:27:17,440 --> 00:27:19,880
Speaker 1: your eyes out. I got mine from a company called

504
00:27:19,920 --> 00:27:23,439
Speaker 1: American Paper Optics. The official safety standard is i S

505
00:27:23,480 --> 00:27:27,439
Speaker 1: O one to three one two dash two and a

506
00:27:27,560 --> 00:27:30,040
Speaker 1: good eclipse glasses will have this code on them if

507
00:27:30,040 --> 00:27:33,720
Speaker 1: you're buying from another company. Actually, the American Astronomical Society

508
00:27:33,720 --> 00:27:37,159
Speaker 1: has a web page where they list known manufacturers of safe,

509
00:27:37,280 --> 00:27:40,560
Speaker 1: legitimate solar viewing glasses, and we will link to that

510
00:27:40,600 --> 00:27:43,800
Speaker 1: page that lists legitimate companies on the landing page for

511
00:27:43,840 --> 00:27:47,440
Speaker 1: this episode. Another thing is maybe you have some eclipse

512
00:27:47,480 --> 00:27:50,040
Speaker 1: glasses that you bought for like I don't know, and

513
00:27:50,119 --> 00:27:53,199
Speaker 1: eclipse ten years ago or something, and you've got them

514
00:27:53,280 --> 00:27:54,840
Speaker 1: lying around the house and you want to pull them

515
00:27:54,840 --> 00:27:59,200
Speaker 1: out and say I'll use these again. Check them. Damaged

516
00:27:59,240 --> 00:28:01,399
Speaker 1: to eclipse glass can hurt you. So you've got to

517
00:28:01,440 --> 00:28:03,679
Speaker 1: make sure that there are no holes, no terrors in

518
00:28:03,720 --> 00:28:06,240
Speaker 1: your glasses or anything like that before looking at the sun.

519
00:28:06,520 --> 00:28:08,720
Speaker 1: You probably just want to invest in some new ones,

520
00:28:09,480 --> 00:28:12,720
Speaker 1: but also a few other options. Uh. You of course

521
00:28:12,800 --> 00:28:16,159
Speaker 1: can use an indirect method like a pinhole camera or

522
00:28:16,200 --> 00:28:17,960
Speaker 1: something like that that's probably gonna be a little bit

523
00:28:18,040 --> 00:28:21,680
Speaker 1: less spectacular. But if you want to see how the

524
00:28:21,760 --> 00:28:24,359
Speaker 1: movement of the Moon across the sun disc is progressing.

525
00:28:24,880 --> 00:28:28,240
Speaker 1: You can, for example, look at shadows on the ground,

526
00:28:28,400 --> 00:28:30,320
Speaker 1: or you can use a pinhole camera or something like

527
00:28:30,359 --> 00:28:33,399
Speaker 1: that that doesn't have you looking directly at the Sun.

528
00:28:34,040 --> 00:28:37,680
Speaker 1: Another option, if you or anyone you know is a welder,

529
00:28:38,240 --> 00:28:41,960
Speaker 1: a mask or goggles with industry standard welding glass will

530
00:28:42,040 --> 00:28:44,800
Speaker 1: be safe, but NASA specifies that it should be a

531
00:28:44,920 --> 00:28:48,800
Speaker 1: number fourteen welding glass or darker. And if you don't

532
00:28:48,800 --> 00:28:51,400
Speaker 1: know whether your welding glass is dark enough, don't risk

533
00:28:51,400 --> 00:28:55,040
Speaker 1: your eyes to find out by some eclipse glasses. Finally,

534
00:28:55,160 --> 00:28:58,280
Speaker 1: there are also telescopes with built in solar filters like

535
00:28:58,320 --> 00:29:02,000
Speaker 1: they're made specially for looking at the Sun and solar astronomy.

536
00:29:02,520 --> 00:29:05,000
Speaker 1: You can look these up online. They're they're pretty interesting.

537
00:29:05,880 --> 00:29:08,920
Speaker 1: One thing, though, is don't try to just wear regular

538
00:29:09,000 --> 00:29:12,840
Speaker 1: eclipse classes when looking through a regular telescope, because the

539
00:29:12,880 --> 00:29:16,760
Speaker 1: telescope may well concentrate what you're looking at and then

540
00:29:16,840 --> 00:29:19,880
Speaker 1: project that and make it too strong for your eclipse

541
00:29:19,880 --> 00:29:22,680
Speaker 1: glasses to filter properly. All right, now, if I have

542
00:29:22,840 --> 00:29:25,320
Speaker 1: none of these things, and I and I wait till

543
00:29:25,320 --> 00:29:27,000
Speaker 1: the last minute, and I go to the store and

544
00:29:27,000 --> 00:29:30,520
Speaker 1: they're out of eclipse glasses, and everybody who has eclipse

545
00:29:30,520 --> 00:29:33,640
Speaker 1: glasses you're planning to wear them. H what's what's my

546
00:29:33,720 --> 00:29:35,560
Speaker 1: and I don't want to go with the with any

547
00:29:35,560 --> 00:29:37,520
Speaker 1: of these other techniques. What are my options? Well, you

548
00:29:37,560 --> 00:29:40,560
Speaker 1: can also check with your local library. That's a good bet.

549
00:29:40,600 --> 00:29:43,360
Speaker 1: A lot of libraries I've seen have eclipse viewing glasses

550
00:29:43,400 --> 00:29:45,640
Speaker 1: that they will give you. They they've had programs to

551
00:29:45,680 --> 00:29:48,800
Speaker 1: distribute these around the country. So if you you're you're

552
00:29:48,840 --> 00:29:51,040
Speaker 1: down to the wire and you still need some check

553
00:29:51,080 --> 00:29:53,640
Speaker 1: with the library. They may have them. All right, Well,

554
00:29:53,760 --> 00:29:55,640
Speaker 1: that note, we're gonna take one more break, and when

555
00:29:55,640 --> 00:29:58,160
Speaker 1: we come back, we're gonna point out some things to

556
00:29:58,760 --> 00:30:01,560
Speaker 1: to look for during the eclipse, and if you have

557
00:30:01,600 --> 00:30:03,600
Speaker 1: already seen it and you're listening to this after the fact,

558
00:30:03,760 --> 00:30:06,600
Speaker 1: these will be things you can reminisce on. And we'll

559
00:30:06,600 --> 00:30:10,280
Speaker 1: also have some sort of a frequently asked questions section

560
00:30:10,400 --> 00:30:13,960
Speaker 1: here with some some additional concerns you might have about

561
00:30:14,040 --> 00:30:16,480
Speaker 1: the eclipse, and we'll try to answer those as well.

562
00:30:20,760 --> 00:30:24,160
Speaker 1: All Right, we're back. Okay, So, assuming you have the

563
00:30:24,480 --> 00:30:29,840
Speaker 1: correct eye protection, assuming you're in the correct geographical location,

564
00:30:30,160 --> 00:30:33,640
Speaker 1: within the line of tortality and assuming the weather is

565
00:30:33,960 --> 00:30:38,800
Speaker 1: being cooperative. Um, what is one going to see? Well,

566
00:30:38,880 --> 00:30:41,479
Speaker 1: the first thing you'll probably see is what's known as

567
00:30:41,560 --> 00:30:44,560
Speaker 1: first contact, and this is when the moon very first

568
00:30:44,560 --> 00:30:47,920
Speaker 1: begins to cross in front of the Sun, partially casting

569
00:30:47,960 --> 00:30:51,160
Speaker 1: its pennumberal shadow. And again at this stage, if you're

570
00:30:51,200 --> 00:30:53,640
Speaker 1: looking at the Sun, you need to be looking through

571
00:30:53,680 --> 00:30:57,160
Speaker 1: a safe filter. So everything I'm gonna say going forward,

572
00:30:57,520 --> 00:31:00,160
Speaker 1: unless I indicate otherwise, you need to have your your

573
00:31:00,160 --> 00:31:04,080
Speaker 1: safety filters on. Over the next hour or so, the

574
00:31:04,120 --> 00:31:06,560
Speaker 1: moon is just going to very slowly continue to cover

575
00:31:06,760 --> 00:31:09,400
Speaker 1: more and more of the Sun. It will go slow

576
00:31:09,560 --> 00:31:11,360
Speaker 1: so you can hang out, you can look at it

577
00:31:11,360 --> 00:31:13,840
Speaker 1: occasionally and see what it's doing. But this is another

578
00:31:13,920 --> 00:31:17,280
Speaker 1: reason for the eye protection, because there's gonna be if

579
00:31:17,280 --> 00:31:18,960
Speaker 1: you did not have eye protection, this would be a

580
00:31:18,960 --> 00:31:21,080
Speaker 1: lot of looking up at the Sun. Like even in

581
00:31:21,200 --> 00:31:23,840
Speaker 1: quick gazes, it's going to quick glances, it's going to

582
00:31:23,880 --> 00:31:26,880
Speaker 1: add up. I mean, I'm not an eyehealth expert. Based

583
00:31:26,880 --> 00:31:30,040
Speaker 1: on I've I've taken my solar eclipse glasses and looked

584
00:31:30,040 --> 00:31:34,959
Speaker 1: at the sun. Um, I probably wouldn't recommend even if

585
00:31:35,000 --> 00:31:37,320
Speaker 1: you have the safety glasses on just staring at the

586
00:31:37,360 --> 00:31:40,240
Speaker 1: sun for hours. I don't know. Maybe they'd be okay,

587
00:31:40,240 --> 00:31:42,400
Speaker 1: but it just it doesn't seem like a great idea.

588
00:31:42,840 --> 00:31:45,680
Speaker 1: I mean, it probably probably confine it to uh to

589
00:31:45,840 --> 00:31:47,520
Speaker 1: as much as you need to look at the sun

590
00:31:47,560 --> 00:31:50,520
Speaker 1: for the eclipse purposes. Okay, when is it going to

591
00:31:50,640 --> 00:31:54,880
Speaker 1: actually start, like changing the way that our world is illuminated? Yeah,

592
00:31:54,920 --> 00:31:58,920
Speaker 1: about maybe three quarters into the covering of the sun.

593
00:31:59,000 --> 00:32:01,760
Speaker 1: Once about three quarters of the way there, you're probably

594
00:32:01,760 --> 00:32:05,040
Speaker 1: gonna notice lights start to change colors, and you will

595
00:32:05,080 --> 00:32:08,600
Speaker 1: notice differences in shadow depth. So you should not just

596
00:32:08,680 --> 00:32:11,160
Speaker 1: look up, but look down and look around the world.

597
00:32:11,520 --> 00:32:14,160
Speaker 1: Notice that you may be casting a different kind of shadow.

598
00:32:14,240 --> 00:32:17,280
Speaker 1: Some contrast may be heightened in the shadow you cast

599
00:32:18,040 --> 00:32:22,040
Speaker 1: versus the general atmosphere. Um, you you may notice some

600
00:32:22,120 --> 00:32:25,120
Speaker 1: strange colors along the horizon and in the sky. So

601
00:32:25,200 --> 00:32:27,280
Speaker 1: this is a time to check out what's going on

602
00:32:27,320 --> 00:32:30,600
Speaker 1: all around you, not just up in the sun. Now.

603
00:32:30,640 --> 00:32:33,440
Speaker 1: Also you can pay attention to how the world feels.

604
00:32:33,520 --> 00:32:36,680
Speaker 1: So as the moon moves in for its final approach

605
00:32:36,760 --> 00:32:41,720
Speaker 1: to totality, you're probably gonna start to notice changes in temperature. Right,

606
00:32:41,880 --> 00:32:45,240
Speaker 1: the temperature can drop, so winds may be affected as

607
00:32:45,280 --> 00:32:48,440
Speaker 1: a rapidly cooling strip of land will cause sudden pressure

608
00:32:48,480 --> 00:32:51,960
Speaker 1: differentials that could draw winds here and there. Yeah, because

609
00:32:51,960 --> 00:32:54,160
Speaker 1: the cycle of night and day has a tremendous effect

610
00:32:54,200 --> 00:32:57,760
Speaker 1: on the movement of air in our atmosphere. Absolutely, and

611
00:32:57,800 --> 00:33:01,800
Speaker 1: then the shadow comes. So here's what they say is

612
00:33:01,800 --> 00:33:05,000
Speaker 1: one of the coolest parts. As the totality approaches, look

613
00:33:05,160 --> 00:33:07,360
Speaker 1: to the west. Figure out this is a good thing

614
00:33:07,400 --> 00:33:09,840
Speaker 1: to do. As soon as you get to wherever you're

615
00:33:09,840 --> 00:33:12,800
Speaker 1: going to be to view the eclipse. Get your bearings.

616
00:33:12,840 --> 00:33:16,600
Speaker 1: So nowhere north, south, east, and west are and as

617
00:33:16,680 --> 00:33:20,280
Speaker 1: the eclipse is approaching, pay attention to the westerly direction,

618
00:33:21,240 --> 00:33:23,400
Speaker 1: so look to the west, especially if you have a

619
00:33:23,440 --> 00:33:25,600
Speaker 1: good vantage point, you may be able to see the

620
00:33:25,640 --> 00:33:30,640
Speaker 1: moon's shadow slowly sweeping across the land like this tide

621
00:33:30,640 --> 00:33:34,320
Speaker 1: of evil magic. Also, look at any clouds in the

622
00:33:34,360 --> 00:33:36,720
Speaker 1: sky to the west of you. You should be able

623
00:33:36,760 --> 00:33:40,480
Speaker 1: to watch the Umbrell shadow of the moon pouring over

624
00:33:40,520 --> 00:33:42,960
Speaker 1: the clouds as it travels west to east. Now, the

625
00:33:43,000 --> 00:33:45,640
Speaker 1: Umbrell shadow, I should have mentioned earlier, but you generally have.

626
00:33:45,720 --> 00:33:48,800
Speaker 1: You've got the Pinnumbrell shadow and the Umbrell shadow. The

627
00:33:48,840 --> 00:33:52,840
Speaker 1: Pinnumbrell shadow is is very wide but not nearly as dark,

628
00:33:53,240 --> 00:33:56,240
Speaker 1: and the Umbrell shadow is the center shadow line. It

629
00:33:56,400 --> 00:33:59,960
Speaker 1: is the very much smaller but much darker center show

630
00:34:00,000 --> 00:34:02,240
Speaker 1: at oh now, the Sun is going to continue to

631
00:34:02,280 --> 00:34:06,120
Speaker 1: shrink more and more behind the Moon's shadow, until almost

632
00:34:06,160 --> 00:34:09,120
Speaker 1: all that's left is this tiny crescent on one side

633
00:34:09,239 --> 00:34:12,240
Speaker 1: and the visible corona, which is going to be the whispy,

634
00:34:12,600 --> 00:34:15,239
Speaker 1: dancing outer atmosphere of the Sun, and that will be

635
00:34:15,239 --> 00:34:18,320
Speaker 1: on the other side from the crescent. In the last

636
00:34:18,320 --> 00:34:21,319
Speaker 1: few seconds before totality, you still got your filters on,

637
00:34:21,360 --> 00:34:26,000
Speaker 1: but you'll get to see something really cool called Bailey's beads. Now.

638
00:34:26,040 --> 00:34:29,120
Speaker 1: This is named after the English astronomer Francis Bailey, who

639
00:34:29,160 --> 00:34:31,560
Speaker 1: described the cause of this in a letter to the

640
00:34:31,640 --> 00:34:35,440
Speaker 1: Royal Astronomical Society in eighty six. And what it will

641
00:34:35,480 --> 00:34:38,799
Speaker 1: be is you'll see the Sun, the bright sun disk

642
00:34:39,000 --> 00:34:42,359
Speaker 1: behind the Moon, and these beads will appear as sort

643
00:34:42,360 --> 00:34:45,839
Speaker 1: of bright jewels of light dotting the edges of the

644
00:34:45,880 --> 00:34:51,120
Speaker 1: black moon disc. What are they? Their topography In places

645
00:34:51,160 --> 00:34:54,440
Speaker 1: where the Moon's surface right along the visible edge of

646
00:34:54,520 --> 00:34:58,840
Speaker 1: the Moon dips into valleys um, the last rays of

647
00:34:58,920 --> 00:35:01,520
Speaker 1: light are going to shine through those valleys and low

648
00:35:01,600 --> 00:35:07,439
Speaker 1: topographical areas before the sun is completely covered. Uh. And

649
00:35:07,520 --> 00:35:10,960
Speaker 1: according to so, a lot of what I've been describing

650
00:35:11,000 --> 00:35:13,680
Speaker 1: here came from some really helpful materials prepared by the

651
00:35:13,680 --> 00:35:17,840
Speaker 1: American Astronomical Society. They recommend that when you see the

652
00:35:18,040 --> 00:35:22,520
Speaker 1: very last Bailey bead, the very only one remains. Uh,

653
00:35:22,560 --> 00:35:25,920
Speaker 1: this is the diamond ring, which is when it's it's

654
00:35:25,960 --> 00:35:28,279
Speaker 1: about time to get ready to take your filters off.

655
00:35:28,760 --> 00:35:31,760
Speaker 1: So the last diamond ring is there, the Bailey's beads

656
00:35:31,760 --> 00:35:33,520
Speaker 1: are down to one, and then you can take your

657
00:35:33,560 --> 00:35:37,360
Speaker 1: filters off and it's totality. The sun will be completely

658
00:35:37,440 --> 00:35:41,040
Speaker 1: hidden and only the corona is there. Uh. So you

659
00:35:41,080 --> 00:35:43,680
Speaker 1: can watch this part with the naked eye, but always

660
00:35:43,760 --> 00:35:46,279
Speaker 1: be conscious while this is going on that you will

661
00:35:46,320 --> 00:35:49,319
Speaker 1: need to replace your filters as soon as the moon

662
00:35:49,400 --> 00:35:52,200
Speaker 1: moves back out on the other side and the totality

663
00:35:52,280 --> 00:35:54,839
Speaker 1: is over. Depending on where you are, it's probably only

664
00:35:54,840 --> 00:35:58,520
Speaker 1: going to be between one in three minutes. Yeah, and

665
00:35:58,640 --> 00:36:01,480
Speaker 1: now they daunting. Part of the for me as a

666
00:36:01,560 --> 00:36:03,360
Speaker 1: parent is that I've I've got to take care of

667
00:36:03,360 --> 00:36:05,360
Speaker 1: my own glasses hearing all this, but I also have

668
00:36:05,440 --> 00:36:08,040
Speaker 1: to make sure my son is putting his back on

669
00:36:08,800 --> 00:36:12,279
Speaker 1: or and or taking them off at the right moment. So, um,

670
00:36:12,719 --> 00:36:15,680
Speaker 1: I feel for anyone who's you know, handling a number

671
00:36:15,719 --> 00:36:20,359
Speaker 1: of children, particularly small children, during this encounter. Yeah, I'm

672
00:36:20,400 --> 00:36:21,840
Speaker 1: not sure what the best way to do that is.

673
00:36:21,880 --> 00:36:24,480
Speaker 1: Maybe one thing would be to research ahead of time,

674
00:36:24,520 --> 00:36:27,280
Speaker 1: because their NASA has maps that can help you figure

675
00:36:27,320 --> 00:36:30,680
Speaker 1: this out. Uh, there are maps that will show you

676
00:36:30,719 --> 00:36:34,120
Speaker 1: about how long totality will last given where you are

677
00:36:34,200 --> 00:36:37,839
Speaker 1: viewing from, and you can use that to maybe set

678
00:36:37,880 --> 00:36:39,560
Speaker 1: a timer ahead of time, if you bring a little

679
00:36:39,640 --> 00:36:41,880
Speaker 1: kitchen timer with you or something like that to set it,

680
00:36:41,920 --> 00:36:45,360
Speaker 1: I don't know, fifteen seconds short of when totality is

681
00:36:45,400 --> 00:36:47,560
Speaker 1: over so you can start getting the filters back on,

682
00:36:47,760 --> 00:36:49,600
Speaker 1: or just I'm thinking I'll just throw a heavy blanket

683
00:36:49,640 --> 00:36:51,839
Speaker 1: over its head at that point, like it's done, it's over,

684
00:36:52,320 --> 00:36:54,480
Speaker 1: go under here. Well, I mean, if you've seen, if

685
00:36:54,480 --> 00:36:57,960
Speaker 1: you've seen the approach with your filters on, and then

686
00:36:58,040 --> 00:37:01,520
Speaker 1: you've seen the the toe total eclipse with the naked eye,

687
00:37:01,880 --> 00:37:04,120
Speaker 1: maybe I don't know, maybe it's less important to see

688
00:37:04,160 --> 00:37:07,080
Speaker 1: the recession of the moon. I don't know. Well, you know,

689
00:37:07,120 --> 00:37:10,279
Speaker 1: sometimes there's an after credit sequence, right, but you know,

690
00:37:10,320 --> 00:37:13,080
Speaker 1: I think a lot of these details are are key,

691
00:37:13,239 --> 00:37:15,520
Speaker 1: especially you know about how the topography of the moon

692
00:37:15,600 --> 00:37:18,040
Speaker 1: coming into play, because it's easy to think of this

693
00:37:18,080 --> 00:37:20,680
Speaker 1: as it's a solar eclipse, it's a solar affair, but

694
00:37:20,719 --> 00:37:22,440
Speaker 1: it's really just as much about the moon, if not

695
00:37:22,480 --> 00:37:25,799
Speaker 1: more about you know, so, uh so, don't forget the

696
00:37:25,840 --> 00:37:29,239
Speaker 1: Moon while you're observing this. Well, it's it's fascinating about

697
00:37:29,239 --> 00:37:31,160
Speaker 1: the Moon in the same way that the lunar eclipse

698
00:37:31,239 --> 00:37:33,680
Speaker 1: is really about the Earth. Yeah, and the Earth gets

699
00:37:33,760 --> 00:37:36,560
Speaker 1: virtually no credit. Right. Well, I mean, here's a cool

700
00:37:36,600 --> 00:37:38,640
Speaker 1: fact about lunar eclipse. I know this is a solar

701
00:37:38,760 --> 00:37:42,560
Speaker 1: solar eclipse episode. When you think about a lunar eclipse,

702
00:37:42,560 --> 00:37:44,400
Speaker 1: what happens generally is that you go in for a

703
00:37:44,400 --> 00:37:47,960
Speaker 1: total lunar eclipse and the moon turns red. Why does

704
00:37:48,000 --> 00:37:50,399
Speaker 1: the moon turn red? How come it doesn't just get

705
00:37:50,400 --> 00:37:53,960
Speaker 1: completely blackened? Because what's happening when you go in for

706
00:37:54,000 --> 00:37:56,680
Speaker 1: a lunar eclipse and the Earth blocks the sunlight from

707
00:37:56,719 --> 00:37:59,360
Speaker 1: hitting the Moon is that you still have some sunlight

708
00:37:59,440 --> 00:38:03,800
Speaker 1: hitting the moon, and it's the sunlight that filters diagonally

709
00:38:03,960 --> 00:38:08,560
Speaker 1: through the Earth's atmosphere. And what happens is that when

710
00:38:08,560 --> 00:38:10,520
Speaker 1: you you know, you notice when you see a sunset,

711
00:38:10,800 --> 00:38:12,520
Speaker 1: the sun is going down, that's when you start to

712
00:38:12,560 --> 00:38:15,319
Speaker 1: see red colors in the sky. And that's generally the

713
00:38:15,480 --> 00:38:18,520
Speaker 1: one of the rare moments when you can look towards

714
00:38:18,560 --> 00:38:21,680
Speaker 1: the sun and view it without because you're you're ultimately

715
00:38:21,760 --> 00:38:24,880
Speaker 1: viewing it through multiple atmospheres where the sun is directly

716
00:38:24,880 --> 00:38:27,359
Speaker 1: above you in the new sky. That's there's like one

717
00:38:27,400 --> 00:38:30,799
Speaker 1: atmosphere is worth of filtration taking place. Even when the

718
00:38:30,800 --> 00:38:33,120
Speaker 1: sun is setting. You should not look to me, don't

719
00:38:33,120 --> 00:38:36,880
Speaker 1: don't look at it, but it's more visible, it's more bearable,

720
00:38:37,120 --> 00:38:39,680
Speaker 1: right kind of you know, glancing way, it's easier to

721
00:38:39,719 --> 00:38:43,120
Speaker 1: do what you shouldn't do at sunset. But you see

722
00:38:43,120 --> 00:38:45,919
Speaker 1: all those red colors because yeah, it's the red wavelengths,

723
00:38:45,920 --> 00:38:49,200
Speaker 1: the longer wavelengths of red light that can travel farther

724
00:38:49,400 --> 00:38:52,440
Speaker 1: through that greater distance in the atmosphere that gets scattered

725
00:38:52,520 --> 00:38:56,160
Speaker 1: less um, and so they travel farther. You see those

726
00:38:56,200 --> 00:38:58,440
Speaker 1: red colors at sunset, and it's for the same reason

727
00:38:58,520 --> 00:39:01,320
Speaker 1: that sun traveling. I think earlier I said diagonally, I

728
00:39:01,360 --> 00:39:04,920
Speaker 1: guess I should have said laterally. Maybe sun traveling laterally

729
00:39:04,960 --> 00:39:07,480
Speaker 1: through the Earth's atmosphere and still splashing on the Moon.

730
00:39:07,800 --> 00:39:10,520
Speaker 1: That you see those red colors. That's the red light

731
00:39:10,600 --> 00:39:14,360
Speaker 1: that survives earth atmosphere to still shine through and around

732
00:39:14,440 --> 00:39:17,200
Speaker 1: onto the Moon. But hey, let's get back to the

733
00:39:17,200 --> 00:39:19,520
Speaker 1: solar eclipse. So the solar eclipse is going on. You've

734
00:39:19,560 --> 00:39:22,399
Speaker 1: hit totality. This is where you are. So the Sun

735
00:39:22,520 --> 00:39:25,600
Speaker 1: is now completely hidden and only the corona remains, and

736
00:39:25,600 --> 00:39:29,640
Speaker 1: the corona is going to be the visible outer atmosphere

737
00:39:29,719 --> 00:39:32,960
Speaker 1: of the Sun. The Sun has an atmosphere like the

738
00:39:32,960 --> 00:39:36,600
Speaker 1: Earth does. It's a layer of plasma, hot gas, and

739
00:39:36,719 --> 00:39:39,759
Speaker 1: magnetic fields extending out into space from the surface of

740
00:39:39,800 --> 00:39:42,799
Speaker 1: the Sun. If you can see it, especially through an

741
00:39:42,800 --> 00:39:48,000
Speaker 1: appropriate telescope, you'll probably notice feathery wisps reaching out into space.

742
00:39:48,520 --> 00:39:52,040
Speaker 1: You might also see some loop shaped structures peeling off

743
00:39:52,080 --> 00:39:54,160
Speaker 1: of the solar limb. That's gonna be the edge of

744
00:39:54,200 --> 00:39:59,040
Speaker 1: the solar silhouette. And these are gigantic tracts of charged

745
00:39:59,160 --> 00:40:03,600
Speaker 1: particles flowing in loop shape magnetic fields projected by the Sun.

746
00:40:04,320 --> 00:40:07,480
Speaker 1: The Sun's corona is actually an interesting subject that astronomers

747
00:40:07,480 --> 00:40:10,040
Speaker 1: are still learning about. So the heated matter in the

748
00:40:10,080 --> 00:40:14,160
Speaker 1: corona is millions of times less dense than the surface

749
00:40:14,200 --> 00:40:17,280
Speaker 1: of the Sun, but it's also hundreds of times hotter.

750
00:40:17,920 --> 00:40:20,960
Speaker 1: A counterintuitive mystery of solar behavior, but that we really

751
00:40:21,000 --> 00:40:24,879
Speaker 1: don't fully understand. The explanation for yet another fact. As

752
00:40:24,920 --> 00:40:28,240
Speaker 1: the plasma in the corona is ejected out into space,

753
00:40:28,640 --> 00:40:32,839
Speaker 1: where does it go. It becomes the solar wind, which

754
00:40:32,840 --> 00:40:36,040
Speaker 1: you've probably heard about in other context, maybe powering our

755
00:40:36,080 --> 00:40:40,120
Speaker 1: future solar sales, or stripping away the ancient atmosphere of

756
00:40:40,160 --> 00:40:43,360
Speaker 1: Mars off into space and leaving it the cold, dry

757
00:40:43,480 --> 00:40:46,360
Speaker 1: rocket is today. So when you look at the eclipse,

758
00:40:46,360 --> 00:40:49,399
Speaker 1: whether through an appropriate telescope or with the naked eye,

759
00:40:49,680 --> 00:40:52,440
Speaker 1: look around the edges and pay attention to what you see.

760
00:40:52,560 --> 00:40:55,640
Speaker 1: What's what's the shape of the corona? What are the contours?

761
00:40:55,960 --> 00:40:59,840
Speaker 1: Can you see any interesting prominences or ejections? And also,

762
00:41:00,120 --> 00:41:03,000
Speaker 1: don't just look at the sun. Look at the world

763
00:41:03,000 --> 00:41:06,120
Speaker 1: around you, look at what's going on on Earth when

764
00:41:06,120 --> 00:41:08,160
Speaker 1: the Sun is hidden. You might you might notice some

765
00:41:08,280 --> 00:41:13,040
Speaker 1: other strange changes in color and temperature. I bet it

766
00:41:13,040 --> 00:41:17,880
Speaker 1: would be cool. If you're a photographer. It's obviously going

767
00:41:17,920 --> 00:41:19,719
Speaker 1: to be really cool to get as many pictures of

768
00:41:19,760 --> 00:41:21,839
Speaker 1: the sky as you can, but you might also want

769
00:41:21,840 --> 00:41:25,279
Speaker 1: to get a picture of what everybody around you is doing. Yeah,

770
00:41:25,280 --> 00:41:27,560
Speaker 1: well yes, uh, I mean you don't want to miss

771
00:41:27,560 --> 00:41:30,040
Speaker 1: the eclipse because you were taking pictures of everybody. But

772
00:41:30,400 --> 00:41:31,880
Speaker 1: maybe that's the way you should set it on a

773
00:41:31,920 --> 00:41:33,680
Speaker 1: tripod and put a time or there. I guess so.

774
00:41:33,800 --> 00:41:37,160
Speaker 1: But then again, uh, photographers, and I'm married to a photographer,

775
00:41:37,200 --> 00:41:38,719
Speaker 1: so I can I can say that they do have

776
00:41:38,760 --> 00:41:42,279
Speaker 1: a tendency to take photos during pivotal events. You know,

777
00:41:42,520 --> 00:41:46,040
Speaker 1: I I am not a photographer person. And what I

778
00:41:46,040 --> 00:41:48,440
Speaker 1: mean not just that I'm not a professional photographer, but

779
00:41:48,480 --> 00:41:52,120
Speaker 1: I noticed there are basically two groups of people. People who,

780
00:41:52,239 --> 00:41:56,799
Speaker 1: when they're experiencing something they anticipate as being memorable, immediately

781
00:41:56,880 --> 00:41:59,600
Speaker 1: want to take pictures of it, and the people who

782
00:41:59,680 --> 00:42:01,520
Speaker 1: don't wanted to take pictures of it. I'm in the

783
00:42:01,600 --> 00:42:04,279
Speaker 1: latter camp, but I totally appreciate the people who are

784
00:42:04,280 --> 00:42:06,440
Speaker 1: in the former camp. I think it's just different ways

785
00:42:06,800 --> 00:42:10,920
Speaker 1: of participating with the anticipation of memory. Well, I look

786
00:42:10,920 --> 00:42:13,319
Speaker 1: at it this way, Like with me, I do try

787
00:42:13,360 --> 00:42:17,640
Speaker 1: to focus more on just experiencing the thing, but not

788
00:42:17,680 --> 00:42:22,080
Speaker 1: being a photographer. My art form is not about capturing

789
00:42:22,200 --> 00:42:25,320
Speaker 1: the moment like that. Like, if I'm going to write

790
00:42:25,360 --> 00:42:29,080
Speaker 1: something about about a really cool event, well then it

791
00:42:29,120 --> 00:42:32,560
Speaker 1: depends on me experiencing it. Whereas a photographer like that,

792
00:42:32,680 --> 00:42:36,520
Speaker 1: their craft, their art is capturing what is happening, So

793
00:42:36,560 --> 00:42:38,160
Speaker 1: of course they have to be there. They have to

794
00:42:38,440 --> 00:42:40,840
Speaker 1: they have to be the one taking pictures during the

795
00:42:40,880 --> 00:42:44,560
Speaker 1: wedding ceremony because because they are capturing it, it's the

796
00:42:44,719 --> 00:42:49,200
Speaker 1: it's dependent upon them not experiencing it. You know, the

797
00:42:49,239 --> 00:42:53,120
Speaker 1: photographer wants to wants to make a record of the truth.

798
00:42:53,320 --> 00:42:57,640
Speaker 1: The writer prepares themselves to lie in the future. That's true.

799
00:42:58,000 --> 00:43:00,320
Speaker 1: That's true. Though I guess you could say that the

800
00:43:00,320 --> 00:43:03,080
Speaker 1: photographer is preparing to lie depending on how many filters

801
00:43:03,320 --> 00:43:06,680
Speaker 1: and how much editing is going on afterwards. That's a

802
00:43:06,680 --> 00:43:08,960
Speaker 1: good point. Well, anyway, I shouldn't tell you what to

803
00:43:08,960 --> 00:43:11,160
Speaker 1: look at. Hey, when the when the eclipse is going on,

804
00:43:11,239 --> 00:43:13,200
Speaker 1: you look at whatever you want to look at. Joe's

805
00:43:13,239 --> 00:43:15,719
Speaker 1: not gonna tell you how what's a look at. He's

806
00:43:15,719 --> 00:43:17,799
Speaker 1: just gonna tell you how exactly to look at it,

807
00:43:17,880 --> 00:43:22,640
Speaker 1: what precautions to say? Which is responsible? Now, like I said,

808
00:43:22,680 --> 00:43:24,640
Speaker 1: it might be helpful to have some kind of timer

809
00:43:24,760 --> 00:43:27,000
Speaker 1: or just to be cognizant of about how long you've

810
00:43:27,040 --> 00:43:29,200
Speaker 1: been looking at the eclipse. Though I've read reports from

811
00:43:29,200 --> 00:43:33,120
Speaker 1: people who have viewed total solar eclipses that you can

812
00:43:33,239 --> 00:43:36,160
Speaker 1: kind of have a lost time experience, like you've been

813
00:43:36,200 --> 00:43:38,240
Speaker 1: looking at this thing for two and a half minutes

814
00:43:38,280 --> 00:43:41,080
Speaker 1: and it felt like a few seconds. It's just gone

815
00:43:41,160 --> 00:43:44,560
Speaker 1: before you realize. But anyway, if you do have some

816
00:43:44,640 --> 00:43:47,320
Speaker 1: way of anticipating that it needs to be time to

817
00:43:47,640 --> 00:43:50,560
Speaker 1: get get your solar filters ready again. Once you see

818
00:43:50,719 --> 00:43:53,960
Speaker 1: the diamond ring quote emerge on the opposite side of

819
00:43:54,000 --> 00:43:56,640
Speaker 1: the sun, once the Bailey's beads start to come back,

820
00:43:57,080 --> 00:43:59,680
Speaker 1: totality is over. And if you want to keep watching,

821
00:43:59,719 --> 00:44:03,200
Speaker 1: that's when you need your filters back on immediately. Uh,

822
00:44:03,480 --> 00:44:05,320
Speaker 1: And you should try to get them on very fast

823
00:44:05,440 --> 00:44:08,319
Speaker 1: because one of the things I was looking at in

824
00:44:08,320 --> 00:44:12,279
Speaker 1: in you know, these optical injuries from sunlight is the

825
00:44:12,400 --> 00:44:15,799
Speaker 1: length of exposure is not necessarily like you don't have

826
00:44:15,840 --> 00:44:17,479
Speaker 1: to be staring at the sun for a long time

827
00:44:17,520 --> 00:44:20,880
Speaker 1: to get injured. Now. Of course, at this point you're

828
00:44:20,920 --> 00:44:23,160
Speaker 1: gonna end up watching the reverse, right, You're gonna watch

829
00:44:23,200 --> 00:44:27,640
Speaker 1: the the moon reveal the Sun. And I think it's

830
00:44:27,680 --> 00:44:31,480
Speaker 1: it's important to to think about this not as like

831
00:44:31,560 --> 00:44:34,200
Speaker 1: the end of the eclipse so much is like the

832
00:44:34,239 --> 00:44:38,120
Speaker 1: rebirth of the sun. Right that you're still watching something amazing.

833
00:44:38,160 --> 00:44:41,719
Speaker 1: You're watching, You're watching the type of sunrise that that

834
00:44:41,920 --> 00:44:45,919
Speaker 1: only occurs, uh, right after a solar eclipse, right after

835
00:44:45,920 --> 00:44:49,040
Speaker 1: a total solar eclipse, you're watching the sun pour out

836
00:44:49,080 --> 00:44:51,640
Speaker 1: of the severed neck of the god Ra who yeah,

837
00:44:51,680 --> 00:44:55,960
Speaker 1: exactly for the demon Ra who well, technically an Osherra.

838
00:44:56,680 --> 00:45:01,719
Speaker 1: So it's yeah, it doesn't necessarily translate one it but hey,

839
00:45:01,880 --> 00:45:05,240
Speaker 1: we understand that probably lots of you out there aren't

840
00:45:05,239 --> 00:45:07,880
Speaker 1: going to be able to view this total solar eclipse,

841
00:45:07,880 --> 00:45:11,319
Speaker 1: and that's understandable. It's it's gonna be cutting right through

842
00:45:11,320 --> 00:45:13,120
Speaker 1: the middle of the United States. But lots of you

843
00:45:13,160 --> 00:45:15,200
Speaker 1: out there are not even in the United States. We

844
00:45:15,239 --> 00:45:18,400
Speaker 1: know lots of you are living in in Europe or Asia,

845
00:45:18,560 --> 00:45:21,239
Speaker 1: South America, Africa. We we've got friends out there all

846
00:45:21,280 --> 00:45:26,080
Speaker 1: over the world. So, uh, you can actually anticipate upcoming

847
00:45:26,320 --> 00:45:30,600
Speaker 1: solar eclipses that might be coming to your area by

848
00:45:30,800 --> 00:45:33,080
Speaker 1: checking out NASA's website. For one thing, they've got a

849
00:45:33,120 --> 00:45:37,520
Speaker 1: really great future eclipses calendar. Yeah, and actually the Wikipedia

850
00:45:37,640 --> 00:45:39,040
Speaker 1: is not bad as well. If you just want to

851
00:45:39,080 --> 00:45:42,680
Speaker 1: see a quick rundown of upcoming solar eclipse and total

852
00:45:42,719 --> 00:45:45,439
Speaker 1: solar eclipse, I mean definitely linked that on the landing page.

853
00:45:45,440 --> 00:45:47,440
Speaker 1: That's stuff to blow your mind dot com. Now, the

854
00:45:47,480 --> 00:45:50,880
Speaker 1: short answer is that, luckily, luckily for you, there's a

855
00:45:50,960 --> 00:45:54,920
Speaker 1: total solar eclipse every year or two. Okay, but you'll

856
00:45:54,960 --> 00:45:57,720
Speaker 1: need to be willing to travel anywhere in the world

857
00:45:57,760 --> 00:46:00,000
Speaker 1: to catch them, all right. I mean, as we said,

858
00:46:00,000 --> 00:46:02,839
Speaker 1: it's not that solar eclipses are rare, it's just that

859
00:46:02,920 --> 00:46:05,600
Speaker 1: they affect such a small portion of the surface of

860
00:46:05,640 --> 00:46:09,080
Speaker 1: the Earth. It's very rare to have one happened near you. Right. So,

861
00:46:09,160 --> 00:46:13,040
Speaker 1: for instance, there'll be another solar eclipse July second, two

862
00:46:13,040 --> 00:46:15,680
Speaker 1: thousand nineteen, but if you want to see it, you

863
00:46:15,719 --> 00:46:18,080
Speaker 1: need to start saving up for a trip to Argentina

864
00:46:18,440 --> 00:46:20,880
Speaker 1: or Chile. Now, if you are in the United States

865
00:46:20,880 --> 00:46:22,640
Speaker 1: but you can't see this one this year, there is

866
00:46:22,680 --> 00:46:25,240
Speaker 1: gonna be another total solar eclipse passing through the United

867
00:46:25,239 --> 00:46:29,839
Speaker 1: States in that's the ways off and well seven years

868
00:46:29,920 --> 00:46:35,359
Speaker 1: from now. But yeah, I mean just stick around. Yeah,

869
00:46:35,480 --> 00:46:38,600
Speaker 1: I can't even it's it's it's ridiculously far in the future,

870
00:46:38,840 --> 00:46:42,400
Speaker 1: and yet not so far in the future. Okay. Frequently

871
00:46:42,440 --> 00:46:46,640
Speaker 1: ask questions with regard to eclipses, How dark will it get, Joe,

872
00:46:46,960 --> 00:46:49,840
Speaker 1: that's a good question. It's gonna be pitch black and

873
00:46:49,880 --> 00:46:51,960
Speaker 1: you won't even be able to see your own hands. No,

874
00:46:52,120 --> 00:46:54,799
Speaker 1: that's not I've heard it described as sort of like

875
00:46:54,840 --> 00:46:59,120
Speaker 1: a sudden twilight about thirty minutes to an hour after sunset.

876
00:47:00,080 --> 00:47:03,360
Speaker 1: But do not go into this expecting pitch black, because

877
00:47:03,360 --> 00:47:07,160
Speaker 1: you will be disappointed. I guess right, all right. Will

878
00:47:07,200 --> 00:47:11,000
Speaker 1: the temperature drop? Yes? Generally that that usually happens during

879
00:47:11,000 --> 00:47:13,560
Speaker 1: a total solar eclipse. The temperature usually drops by an

880
00:47:13,560 --> 00:47:17,200
Speaker 1: average about ten degrees fahrenheit or about five degrees celsius

881
00:47:17,600 --> 00:47:20,919
Speaker 1: within the line of totality. Not so for the line

882
00:47:20,960 --> 00:47:24,120
Speaker 1: of partial eclipse. Maybe that's not a line the huge

883
00:47:24,120 --> 00:47:27,239
Speaker 1: swath of partial eclipse, and there have been cases where

884
00:47:27,239 --> 00:47:30,480
Speaker 1: it dropped much more. The change should be similar to

885
00:47:30,520 --> 00:47:33,799
Speaker 1: a sudden transition between the temperature of midday in the

886
00:47:33,840 --> 00:47:37,880
Speaker 1: temperature after sunset. Uh. There was one article I was

887
00:47:37,920 --> 00:47:40,040
Speaker 1: reading that that told a story about how during a

888
00:47:40,080 --> 00:47:42,480
Speaker 1: total solar eclipse in the in the United States in

889
00:47:42,600 --> 00:47:47,439
Speaker 1: eighteen thirty four, temperature was recorded as dropping as much

890
00:47:47,480 --> 00:47:51,120
Speaker 1: as twenty eight degrees fahrenheit from seventy eight degrees fahrenheit

891
00:47:51,160 --> 00:47:55,040
Speaker 1: to fifty degrees fahrenheit, which is I guess that would

892
00:47:55,080 --> 00:47:58,719
Speaker 1: also be dropping about fifteen degrees celsius. So who knows

893
00:47:58,760 --> 00:48:02,439
Speaker 1: what's going to happen. But but yeah, maybe maybe it'll

894
00:48:02,440 --> 00:48:04,160
Speaker 1: get very chilly. You might want to bring a jacket,

895
00:48:04,360 --> 00:48:09,080
Speaker 1: all right now. You also might be bringing a pet

896
00:48:09,160 --> 00:48:11,560
Speaker 1: with you. I know, Joe, you you have a dog,

897
00:48:11,600 --> 00:48:14,520
Speaker 1: Your dog, Charlie is is if you do travel, are

898
00:48:14,520 --> 00:48:17,680
Speaker 1: you taking Charlie as well? We almost always take Charlie

899
00:48:17,680 --> 00:48:20,319
Speaker 1: as well. If we can get away with taking him,

900
00:48:20,320 --> 00:48:22,840
Speaker 1: we'll take him. All right. Well this, you know, a

901
00:48:22,840 --> 00:48:24,680
Speaker 1: lot of people have asked about this, and I see

902
00:48:24,719 --> 00:48:28,920
Speaker 1: I actually see this question popping up online, and sometimes

903
00:48:28,920 --> 00:48:32,160
Speaker 1: the answers are not that great or not that that factual.

904
00:48:33,360 --> 00:48:35,839
Speaker 1: I'm gonna be straightforward. I've seen a lot of what

905
00:48:35,880 --> 00:48:39,800
Speaker 1: looks like bs about people saying that animals go berserk

906
00:48:39,960 --> 00:48:43,560
Speaker 1: during an eclipse. I have not seen anything that looks

907
00:48:43,600 --> 00:48:46,920
Speaker 1: like a good, reputable source claiming that it's more just

908
00:48:47,000 --> 00:48:50,200
Speaker 1: kind of like dumb looking websites. Now, there are some

909
00:48:50,239 --> 00:48:52,799
Speaker 1: reports here and they're going back throughout history of like

910
00:48:52,920 --> 00:48:58,200
Speaker 1: individual observations of animals acting a bit unusual for daytime behavior.

911
00:48:58,320 --> 00:49:01,000
Speaker 1: That might happen. They might make different sounds, they might

912
00:49:01,440 --> 00:49:04,839
Speaker 1: they might become more visible or less visible. But what

913
00:49:04,880 --> 00:49:09,520
Speaker 1: I do not predict is ecological pandemonium and widespread animal

914
00:49:09,600 --> 00:49:12,719
Speaker 1: freak outs. Based on what I've looked at and the

915
00:49:12,800 --> 00:49:16,680
Speaker 1: science I've liked that, Uh, there's nothing magic is going

916
00:49:16,760 --> 00:49:19,920
Speaker 1: to happen in regard to your pet during the solar eclipse.

917
00:49:20,080 --> 00:49:23,359
Speaker 1: So animals simply tend to react to the darkness as

918
00:49:23,440 --> 00:49:27,120
Speaker 1: if it were occurring during the typical cycle. So scientists

919
00:49:27,160 --> 00:49:30,880
Speaker 1: have that have observed this in the vertical migration of

920
00:49:31,160 --> 00:49:34,000
Speaker 1: zooplankton in the ocean due to lunar eclipses, as well

921
00:49:34,040 --> 00:49:37,560
Speaker 1: as the countless larger animals when it comes to solar eclipses.

922
00:49:37,600 --> 00:49:40,680
Speaker 1: So you know, likelihood, it's possible you might hear some

923
00:49:40,840 --> 00:49:46,080
Speaker 1: twilight animal noises uh during the eclipse, but that's gonna

924
00:49:46,080 --> 00:49:47,400
Speaker 1: be the extent of it. Dogs are not going to

925
00:49:47,480 --> 00:49:51,120
Speaker 1: turn into cats. Cats are not going to turn into dogs. Uh,

926
00:49:51,200 --> 00:49:54,440
Speaker 1: that's gonna be the the extent. So hamsters might turn

927
00:49:54,480 --> 00:49:59,520
Speaker 1: into crayfish. Well, yes, but but for reasons unrelated to

928
00:49:59,560 --> 00:50:04,359
Speaker 1: the solar eclips Roughly speaking, diurnal animals react as though

929
00:50:04,480 --> 00:50:07,800
Speaker 1: night we're approaching, and this is this is demonstrated and

930
00:50:07,880 --> 00:50:11,799
Speaker 1: expedited roosting and betting behavior. In contrast animals that are

931
00:50:11,840 --> 00:50:15,680
Speaker 1: normally active at night. Uh. Nocturnal animals like bats, they

932
00:50:15,680 --> 00:50:18,719
Speaker 1: may show the reverse pattern, emerging in the into the

933
00:50:18,760 --> 00:50:21,560
Speaker 1: open as the sky darkens during an eclipse. So actually

934
00:50:21,600 --> 00:50:25,440
Speaker 1: I would be very interested if anyone you know, can

935
00:50:26,040 --> 00:50:28,120
Speaker 1: look away from the eclipse long enough to notice what

936
00:50:28,160 --> 00:50:30,799
Speaker 1: animals are doing, If you see any bats come out,

937
00:50:30,840 --> 00:50:32,760
Speaker 1: I would love to hear about that. If there's any

938
00:50:32,800 --> 00:50:37,640
Speaker 1: any any sightings of nocturnal animals at least stirring, does

939
00:50:37,680 --> 00:50:41,880
Speaker 1: club life get going? I will will come back to that.

940
00:50:41,960 --> 00:50:44,880
Speaker 1: I have I have a question too about that myself. Now,

941
00:50:45,600 --> 00:50:49,440
Speaker 1: as you mentioned some websites they are talking about, oh,

942
00:50:49,480 --> 00:50:52,240
Speaker 1: there's gonna be a full fledged freak out of pets

943
00:50:52,239 --> 00:50:55,719
Speaker 1: in the eclipse uh. And I don't think that is

944
00:50:55,760 --> 00:50:59,040
Speaker 1: going to happen. But one thing, one point that has

945
00:50:59,080 --> 00:51:01,279
Speaker 1: been made is that if you were hanging out with

946
00:51:01,320 --> 00:51:04,920
Speaker 1: a lot of people during the eclipse, sometimes people get

947
00:51:05,000 --> 00:51:07,000
Speaker 1: high spirited, They make a lot of noise, they kind

948
00:51:07,000 --> 00:51:09,120
Speaker 1: of celebrate because it is an amazing thing to see.

949
00:51:09,480 --> 00:51:13,280
Speaker 1: If your pet dog, for instance, or certainly your pet cat,

950
00:51:13,280 --> 00:51:15,600
Speaker 1: which you for some reason brought into the wilderness of

951
00:51:15,640 --> 00:51:18,279
Speaker 1: view and eclipse, if they if they kind of freak

952
00:51:18,360 --> 00:51:20,919
Speaker 1: out when people are freaking out, well then that might

953
00:51:20,960 --> 00:51:23,239
Speaker 1: be a problem. Or if you just got your cat

954
00:51:23,280 --> 00:51:25,560
Speaker 1: in that cardboard box, people used to take it to

955
00:51:25,600 --> 00:51:29,279
Speaker 1: the vet. Yes, so you know, ultimately, you know your pet.

956
00:51:29,320 --> 00:51:32,640
Speaker 1: You know how your pet reacts to issues, you know,

957
00:51:32,760 --> 00:51:37,959
Speaker 1: unrelated to to the total eclipse of the sun. Uh,

958
00:51:38,239 --> 00:51:40,160
Speaker 1: you know, you can judge this best, but there's not

959
00:51:40,160 --> 00:51:43,200
Speaker 1: gonna be any kind of magical reaction, uh, you know

960
00:51:43,280 --> 00:51:46,120
Speaker 1: in your pet caused by the sun. They're not going

961
00:51:46,200 --> 00:51:49,440
Speaker 1: to be wild animals. They're gonna be behaving in a

962
00:51:49,480 --> 00:51:52,000
Speaker 1: way that's going to be you know, immediately noticeable to

963
00:51:52,040 --> 00:51:54,440
Speaker 1: you most likely. All right now, but here's a question

964
00:51:54,480 --> 00:51:59,400
Speaker 1: that arises regarding not animals, but but human technology and

965
00:51:59,480 --> 00:52:03,560
Speaker 1: other kind of zoo Is this going to cause car accidents? This,

966
00:52:03,600 --> 00:52:05,279
Speaker 1: of course, I guess, is assuming that they're going to

967
00:52:05,320 --> 00:52:08,640
Speaker 1: be people driving around not expecting a cellar eclipse, and

968
00:52:08,680 --> 00:52:12,040
Speaker 1: then it just occurs and people you know, drive off

969
00:52:12,040 --> 00:52:14,600
Speaker 1: the road and run into each other. It might cause

970
00:52:14,680 --> 00:52:17,840
Speaker 1: car accidents, but I think much more likely is that

971
00:52:17,920 --> 00:52:22,120
Speaker 1: it will cause extreme traffic congestion. They're gonna be people

972
00:52:22,160 --> 00:52:25,840
Speaker 1: from everywhere descending on a strip of the United States.

973
00:52:25,880 --> 00:52:29,880
Speaker 1: It's only about seventy miles or ten kilometers wide, and

974
00:52:29,960 --> 00:52:33,000
Speaker 1: mostly they're going to be getting there by roads. So seriously,

975
00:52:33,680 --> 00:52:36,239
Speaker 1: if you are going to be in the line of totality,

976
00:52:36,640 --> 00:52:40,640
Speaker 1: you should expect the traffic situation to go plaid. It's

977
00:52:40,680 --> 00:52:44,600
Speaker 1: it's gonna be crazy. I can fully predict now, I've

978
00:52:44,680 --> 00:52:46,759
Speaker 1: just seen a few examples. There is actually a good

979
00:52:46,760 --> 00:52:50,320
Speaker 1: house Stuff Works article about this about how the upcoming

980
00:52:50,320 --> 00:52:55,000
Speaker 1: eclipse will impact transportation. Oregon state officials are expecting an

981
00:52:55,000 --> 00:52:58,359
Speaker 1: influx of more than a million people into the line

982
00:52:58,360 --> 00:53:04,160
Speaker 1: of totality Idaho. Idaho is expecting half a million visitors.

983
00:53:04,480 --> 00:53:07,320
Speaker 1: The population of Idaho is only about one point seven

984
00:53:07,400 --> 00:53:11,080
Speaker 1: million people. The state's population is going to increase by

985
00:53:11,120 --> 00:53:14,719
Speaker 1: almost one third in the in the line of totality.

986
00:53:15,640 --> 00:53:19,160
Speaker 1: Missouri officials expect more than a million people. The city

987
00:53:19,160 --> 00:53:22,640
Speaker 1: of Columbia, South Carolina, is expected to temporarily more than

988
00:53:22,760 --> 00:53:27,280
Speaker 1: double in population. So if you're traveling for the eclipse.

989
00:53:28,360 --> 00:53:30,759
Speaker 1: First of all, this might be obvious, but I feel

990
00:53:30,800 --> 00:53:32,880
Speaker 1: I should say it. Don't try to look at the

991
00:53:32,920 --> 00:53:36,240
Speaker 1: eclipse while you're driving or while the car is moving.

992
00:53:36,640 --> 00:53:38,919
Speaker 1: Pick out a viewing spot ahead of time, and get

993
00:53:38,960 --> 00:53:43,400
Speaker 1: there early, real early. Also, don't pull over on the

994
00:53:43,440 --> 00:53:45,600
Speaker 1: side of a highway or a freeway to watch. This

995
00:53:45,680 --> 00:53:48,359
Speaker 1: is just going to further congest traffic and it may

996
00:53:48,400 --> 00:53:52,440
Speaker 1: block emergency vehicles that need to get somewhere. Don't do it. Instead,

997
00:53:52,680 --> 00:53:56,080
Speaker 1: plan ahead, figure out where you're going, pick out a

998
00:53:56,120 --> 00:53:59,040
Speaker 1: place or a place to park, or stay ahead of

999
00:53:59,080 --> 00:54:02,680
Speaker 1: time and get their early. Uh. And also expect to

1000
00:54:02,719 --> 00:54:04,560
Speaker 1: have to wait a long time to get home. I

1001
00:54:04,560 --> 00:54:07,520
Speaker 1: imagine the highways are probably going to be clogged up.

1002
00:54:07,560 --> 00:54:09,520
Speaker 1: If if you're gonna be trying to get back home

1003
00:54:09,560 --> 00:54:13,799
Speaker 1: wherever you came from that day, it might be a problem. Yeah.

1004
00:54:13,840 --> 00:54:17,040
Speaker 1: I think it was Georgia Department of Transportation that was

1005
00:54:17,480 --> 00:54:20,120
Speaker 1: warning against the becoming a I think the quote was

1006
00:54:20,920 --> 00:54:24,600
Speaker 1: an eclipse refugee where you the idea. I guess as

1007
00:54:24,600 --> 00:54:26,840
Speaker 1: you set out without a real plan in mind, and

1008
00:54:26,840 --> 00:54:29,200
Speaker 1: either you get bogged down in traffic or you are

1009
00:54:29,280 --> 00:54:31,719
Speaker 1: expecting to find room and board in the line of

1010
00:54:31,760 --> 00:54:35,279
Speaker 1: totality and you cannot find it, and then you're reduced to,

1011
00:54:35,440 --> 00:54:37,560
Speaker 1: you know, sleeping in your car or something. So yeah,

1012
00:54:37,640 --> 00:54:40,960
Speaker 1: plan ahead, take supplies, figure out where you're gonna go

1013
00:54:41,160 --> 00:54:43,359
Speaker 1: ahead of time, and a place where you can park

1014
00:54:43,400 --> 00:54:45,600
Speaker 1: your car if you're going by car. And bear in

1015
00:54:45,640 --> 00:54:48,279
Speaker 1: mind that if you're hoping to perform some you know,

1016
00:54:48,680 --> 00:54:52,560
Speaker 1: sacred pagan ritual uh during the eclipse. Uh, you know,

1017
00:54:52,600 --> 00:54:55,880
Speaker 1: make sure you have space set aside. Right, don't do

1018
00:54:56,000 --> 00:54:59,080
Speaker 1: that in the middle of the highway. Don't have enough problems,

1019
00:54:59,400 --> 00:55:01,400
Speaker 1: you know. Do you know? We didn't actually prepare too

1020
00:55:01,480 --> 00:55:04,640
Speaker 1: much for a discussion of religious right related to eclipse.

1021
00:55:04,680 --> 00:55:07,759
Speaker 1: But if i'm if I'm not mistaken, I believe there

1022
00:55:07,800 --> 00:55:14,520
Speaker 1: are a particular Islamic prayers that or prayer rituals that

1023
00:55:14,560 --> 00:55:17,560
Speaker 1: take place during a solar eclipse. Hadn't heard that, but

1024
00:55:17,640 --> 00:55:20,560
Speaker 1: I know we have a few uh Islamic listeners out there.

1025
00:55:20,600 --> 00:55:23,319
Speaker 1: Maybe they can provide some more details about that, because

1026
00:55:23,320 --> 00:55:25,680
Speaker 1: in general, I would love to hear from anybody out

1027
00:55:25,719 --> 00:55:29,760
Speaker 1: there regarding their experience with this eclipse. Oh yeah, definitely,

1028
00:55:29,840 --> 00:55:31,799
Speaker 1: would you do how did you do it? I know,

1029
00:55:32,320 --> 00:55:35,120
Speaker 1: I know in recent decades, whenever there's been a good eclipse, like,

1030
00:55:35,160 --> 00:55:38,520
Speaker 1: the Pagans come out in full force, for they eat

1031
00:55:38,560 --> 00:55:41,279
Speaker 1: this stuff up. Also, are you a pagan? Yeah, so

1032
00:55:41,360 --> 00:55:43,440
Speaker 1: we want to hear what you're doing. Okay, what other

1033
00:55:43,560 --> 00:55:47,040
Speaker 1: additional questions do we have here? Show Well, uh, here's

1034
00:55:47,120 --> 00:55:50,719
Speaker 1: kind of a bummer one. But what if it's really cloudy? Then? Uh,

1035
00:55:51,000 --> 00:55:53,960
Speaker 1: then we have some bad news for you. Yeah, surely,

1036
00:55:53,960 --> 00:55:56,239
Speaker 1: no getting around that is. Yeah, I mean depends on

1037
00:55:56,280 --> 00:55:58,200
Speaker 1: how you know what kind of cloud cover we're talking,

1038
00:55:58,320 --> 00:56:00,839
Speaker 1: but that's generally going to be bad news. But let's

1039
00:56:00,880 --> 00:56:02,400
Speaker 1: not try to We're not going to think about that.

1040
00:56:02,400 --> 00:56:04,680
Speaker 1: We're not gonna focus on the possibility of clouds. One

1041
00:56:04,680 --> 00:56:07,880
Speaker 1: thing is if you are looking at the weather forecasts,

1042
00:56:08,040 --> 00:56:12,200
Speaker 1: say right now, the day you're the day this episode

1043
00:56:12,239 --> 00:56:14,600
Speaker 1: comes out, and you're like, oh no, it looks like

1044
00:56:14,640 --> 00:56:17,440
Speaker 1: it's going to be cloudy. Don't lose hope yet, because

1045
00:56:17,520 --> 00:56:20,319
Speaker 1: weather forecast that far out, you know, are not at

1046
00:56:20,320 --> 00:56:23,640
Speaker 1: their peak accuracy. Keep checking the weather forecast, says the

1047
00:56:23,719 --> 00:56:25,840
Speaker 1: day gets closer and closer each day, it's going to

1048
00:56:25,920 --> 00:56:28,920
Speaker 1: get more and more accurate, right, and maybe hey, if

1049
00:56:29,000 --> 00:56:31,359
Speaker 1: the forecast is clouding, maybe that will cut down on

1050
00:56:31,440 --> 00:56:33,799
Speaker 1: some of the other individuals planning to be there, be there,

1051
00:56:34,040 --> 00:56:37,319
Speaker 1: and you'll be able to drive there faster. All right,

1052
00:56:37,360 --> 00:56:39,920
Speaker 1: what else do we have question wise? I see we

1053
00:56:40,000 --> 00:56:44,440
Speaker 1: have a question about the purge. Oh yeah, will purge

1054
00:56:44,520 --> 00:56:48,920
Speaker 1: laws really apply during solar eclips No, all all laws

1055
00:56:48,960 --> 00:56:53,160
Speaker 1: are federal, state, local are still going to apply. However,

1056
00:56:53,760 --> 00:56:57,080
Speaker 1: in addition to traffic concerns, there are local concerns. In

1057
00:56:57,200 --> 00:57:01,359
Speaker 1: certain eclipse hotspots. You're gonna you're gonna have, you know,

1058
00:57:01,760 --> 00:57:04,520
Speaker 1: this huge increase in visitors, like you say, and doubling

1059
00:57:04,520 --> 00:57:07,279
Speaker 1: the populations, and some of these such these travelers are

1060
00:57:07,280 --> 00:57:10,360
Speaker 1: gonna be international travelers as well. So there's gonna be

1061
00:57:10,400 --> 00:57:15,680
Speaker 1: this possibility for more crime, more misunderstanding just by virtually

1062
00:57:15,680 --> 00:57:19,200
Speaker 1: there just being that many more people around, right, Possibly, yeah,

1063
00:57:19,280 --> 00:57:21,400
Speaker 1: I mean, just you're gonna have more fender benders. Potentially,

1064
00:57:21,440 --> 00:57:23,600
Speaker 1: you're gonna have more people bumping into each other, just

1065
00:57:23,680 --> 00:57:26,960
Speaker 1: more people being around other people. Here, here's some good

1066
00:57:27,080 --> 00:57:30,040
Speaker 1: eclipse advice that may be hard to abide because it's

1067
00:57:30,040 --> 00:57:34,280
Speaker 1: easy to say, chill out, you know, just set your

1068
00:57:34,320 --> 00:57:36,600
Speaker 1: day aside, if if you're if you're able to take

1069
00:57:36,600 --> 00:57:39,600
Speaker 1: off work and all that to to do your eclipse viewing.

1070
00:57:40,000 --> 00:57:42,520
Speaker 1: Just accept that there's going to be some delays, that

1071
00:57:42,560 --> 00:57:44,880
Speaker 1: they're going to be crowds, that there's gonna be a traffic.

1072
00:57:45,000 --> 00:57:48,120
Speaker 1: Just make that part of your plan, and when it happens,

1073
00:57:48,160 --> 00:57:49,760
Speaker 1: you'll be ready for it and you're not gonna get

1074
00:57:49,760 --> 00:57:53,439
Speaker 1: frustrated and upset. All right. I have one final question here,

1075
00:57:53,440 --> 00:57:54,600
Speaker 1: and this is one I don't really have a good

1076
00:57:54,600 --> 00:57:57,840
Speaker 1: answer for. Wait, let me guess what it is. Okay, So,

1077
00:57:57,960 --> 00:58:00,760
Speaker 1: since so many people think that the eclipse is going

1078
00:58:00,800 --> 00:58:02,320
Speaker 1: to be like the end of the world, have any

1079
00:58:02,520 --> 00:58:06,560
Speaker 1: previous eclipse has been the end of time? Um? No,

1080
00:58:07,080 --> 00:58:09,200
Speaker 1: unless I guess if you died during an eclipse, then

1081
00:58:09,240 --> 00:58:12,120
Speaker 1: it would technically be for you the end of time.

1082
00:58:12,400 --> 00:58:15,120
Speaker 1: But I I don't think I ran across any examples

1083
00:58:15,120 --> 00:58:17,880
Speaker 1: of that happening, So you're probably good, you know. I mean,

1084
00:58:17,880 --> 00:58:19,960
Speaker 1: the timing would have to be particularly cruel for that

1085
00:58:20,000 --> 00:58:22,040
Speaker 1: to or perfect for that to take place. I mean,

1086
00:58:22,080 --> 00:58:24,520
Speaker 1: if you've got to go whine I during an eclipse.

1087
00:58:25,240 --> 00:58:29,280
Speaker 1: Now that's one question. But but one question that I'm

1088
00:58:29,360 --> 00:58:33,800
Speaker 1: legitimately wondering about a little bit. Is it legally night

1089
00:58:34,360 --> 00:58:36,400
Speaker 1: during a solar clips we talked about it's not gonna

1090
00:58:36,400 --> 00:58:39,800
Speaker 1: be completely dark, but it's not really day. I wonder

1091
00:58:40,120 --> 00:58:44,600
Speaker 1: are there any actual weird legal shenanigans out there that

1092
00:58:44,640 --> 00:58:47,880
Speaker 1: someone could potentially exploit. What would that affect you mean, like,

1093
00:58:48,080 --> 00:58:49,800
Speaker 1: if there's like a law that says, like you have

1094
00:58:49,840 --> 00:58:52,360
Speaker 1: to drive with your headlights on at night or something

1095
00:58:52,400 --> 00:58:55,680
Speaker 1: like that. Yeah, or like it's it's legal to it's

1096
00:58:55,720 --> 00:58:59,440
Speaker 1: only legal to sell beer in a certain county after dusk,

1097
00:58:59,560 --> 00:59:02,680
Speaker 1: you know, things of that nature. I guess the problem

1098
00:59:02,760 --> 00:59:05,120
Speaker 1: is that the eclipse is not going to last long

1099
00:59:05,240 --> 00:59:08,160
Speaker 1: enough for anyone to explod it. To exploit it, you

1100
00:59:08,160 --> 00:59:11,400
Speaker 1: want to spend your your eclipse, the one moment of

1101
00:59:11,480 --> 00:59:14,600
Speaker 1: time you might have to look at this beautiful phenomenon.

1102
00:59:14,680 --> 00:59:17,479
Speaker 1: You're gonna spend the store getting a case of beer. Yeah,

1103
00:59:17,720 --> 00:59:21,480
Speaker 1: I guess, you know, or um, you know, or I

1104
00:59:21,520 --> 00:59:23,720
Speaker 1: guess it could be a situation where, Okay, there's a

1105
00:59:23,800 --> 00:59:26,320
Speaker 1: there's a state law that says during the day, you

1106
00:59:26,360 --> 00:59:29,800
Speaker 1: can only air episodes of Baywatch, and you can only

1107
00:59:29,920 --> 00:59:33,840
Speaker 1: air episodes of Baywatch after dark. After dark? Is that

1108
00:59:33,960 --> 00:59:36,440
Speaker 1: this would allow you to air at least, you know,

1109
00:59:36,480 --> 00:59:39,760
Speaker 1: a couple of minutes of a Baywatch after Dark episode. Now,

1110
00:59:39,840 --> 00:59:43,240
Speaker 1: I wonder if anybody out there is marketing special eclipse

1111
00:59:43,720 --> 00:59:47,160
Speaker 1: themed products. I was thinking, beer, are they making like

1112
00:59:47,200 --> 00:59:50,040
Speaker 1: a bud Eclipse that's like a new version of Bud

1113
00:59:50,080 --> 00:59:51,960
Speaker 1: Light that have something? I mean, it sounds like a

1114
00:59:52,000 --> 00:59:54,560
Speaker 1: perfect tie in, right, Like here's the beer you drink

1115
00:59:54,680 --> 00:59:58,360
Speaker 1: during the solar eclipse. Get it now? Uh, you know,

1116
00:59:58,440 --> 01:00:00,640
Speaker 1: and and love it for you know three minut We

1117
01:00:00,680 --> 01:00:03,160
Speaker 1: have to issue so many warnings here. Please don't take

1118
01:00:03,160 --> 01:00:06,680
Speaker 1: that as us encouraging irresponsible drinking during the eclipse, especially

1119
01:00:06,680 --> 01:00:10,480
Speaker 1: if you're going to be doing any of the drivings. Yeah, please, please,

1120
01:00:10,560 --> 01:00:13,560
Speaker 1: please do a responsible eclipse viewing. I want to say

1121
01:00:13,600 --> 01:00:15,760
Speaker 1: in there's some sort of OREO thing getting there, an

1122
01:00:15,800 --> 01:00:18,520
Speaker 1: eclipse oreo or it seems like there is some sort

1123
01:00:18,520 --> 01:00:20,280
Speaker 1: of commercial tie in now that I think about it,

1124
01:00:20,520 --> 01:00:23,960
Speaker 1: I know Taquda Banana has been doing these bizarre eclipse

1125
01:00:24,000 --> 01:00:27,920
Speaker 1: commercials where they're suggesting that the sun will briefly become

1126
01:00:27,960 --> 01:00:31,919
Speaker 1: a banana as the moon is moving in on its territory. Well,

1127
01:00:32,000 --> 01:00:34,840
Speaker 1: I'm very pro banana, but it does seem like a

1128
01:00:34,920 --> 01:00:39,000
Speaker 1: stretched by and the banana is the official eclipse the

1129
01:00:39,080 --> 01:00:42,200
Speaker 1: snack item, all right, so there you have it, that

1130
01:00:42,280 --> 01:00:45,960
Speaker 1: the basics for the eclipse, the upcoming eclipse, or perhaps

1131
01:00:46,000 --> 01:00:49,440
Speaker 1: the eclipse you just saw. Hopefully we've provided you a

1132
01:00:49,480 --> 01:00:52,360
Speaker 1: little more insight and maybe even a little more preparation.

1133
01:00:52,920 --> 01:00:56,600
Speaker 1: And hey, if you are currently stuck in an automobile

1134
01:00:57,320 --> 01:01:00,440
Speaker 1: traveling to or from the eclipse and you're thinking yourself,

1135
01:01:00,560 --> 01:01:02,600
Speaker 1: we'll have all this, all this time in front of me.

1136
01:01:02,800 --> 01:01:05,120
Speaker 1: What are some more podcast episodes I can listen to

1137
01:01:05,560 --> 01:01:08,440

01:01:13,560 --> 01:01:16,560
Speaker 1: of the myths in greater depth. Hey, and not too

Speaker 1: sacrifice of kings and king figures. And one of the

1144
01:01:27,760 --> 01:01:30,560
Speaker 1: things we talked about in that episode was the the

1145
01:01:30,640 --> 01:01:34,600
Speaker 1: eclipse King of ancient Babylon ancient Assyria, where you would

1146
01:01:34,640 --> 01:01:36,960
Speaker 1: have an eclipse that was and there was an ill

1147
01:01:37,000 --> 01:01:39,240
Speaker 1: omen for the king and you might have to put

1148
01:01:39,280 --> 01:01:43,160
Speaker 1: in another king to absorb that curse. Right. So hey,
