1 00:00:03,800 --> 00:00:06,680 Speaker 1: Welcome to Stuff to Blow Your Mind from how stuff 2 00:00:06,720 --> 00:00:14,160 Speaker 1: Works dot com. Hey, welcome to Stuff to Blow your Mind. 3 00:00:14,280 --> 00:00:16,640 Speaker 1: My name is Robert Lamb and my name is Julie Douglas. 4 00:00:16,960 --> 00:00:20,200 Speaker 1: And this week we have been super busy on a 5 00:00:20,320 --> 00:00:22,919 Speaker 1: new and exciting product. Do you want to tell everybody 6 00:00:22,960 --> 00:00:25,319 Speaker 1: what this is? Yes, it is something called Stuff to 7 00:00:25,440 --> 00:00:28,840 Speaker 1: Blow Your Kid's Mind, and it's a video series. It's 8 00:00:28,840 --> 00:00:32,040 Speaker 1: being sponsored by B A s F. And we have 9 00:00:32,159 --> 00:00:35,560 Speaker 1: been hard at work along with our video crew here, 10 00:00:36,159 --> 00:00:39,440 Speaker 1: immensely talented video crew, I should say. We've been just 11 00:00:39,479 --> 00:00:43,440 Speaker 1: putting together episodes that are based on experiments out there 12 00:00:43,479 --> 00:00:45,720 Speaker 1: that kids do and then kind of talking about the 13 00:00:45,840 --> 00:00:49,720 Speaker 1: ramifications of the you know, physics or the science behind 14 00:00:49,720 --> 00:00:53,440 Speaker 1: those experiments in our daily lives. And it's been really cool. Yeah. Well, 15 00:00:53,720 --> 00:00:56,240 Speaker 1: we've put together ten of these puppies in an absurdly 16 00:00:56,280 --> 00:00:58,760 Speaker 1: short period of time, but we're really excited about the 17 00:00:58,760 --> 00:01:01,920 Speaker 1: product because each one is three segments. The first segment 18 00:01:01,960 --> 00:01:04,360 Speaker 1: is that experiment where we do, like sometimes it's something 19 00:01:04,400 --> 00:01:07,200 Speaker 1: as simple as a science lab volcano kind of a thing, 20 00:01:07,400 --> 00:01:10,800 Speaker 1: or rubbing a balloon on your hair making it stick up, 21 00:01:11,360 --> 00:01:14,039 Speaker 1: which was pretty awesome because that's not something I normally 22 00:01:14,080 --> 00:01:16,839 Speaker 1: do to your hair. It's not so In the first segment, 23 00:01:16,880 --> 00:01:19,200 Speaker 1: we conduct these experiments, and then we do two additional 24 00:01:19,240 --> 00:01:21,760 Speaker 1: segments where we really get into the stuff to blow 25 00:01:21,800 --> 00:01:24,600 Speaker 1: your mind kind of territory with these experiments and talk 26 00:01:24,600 --> 00:01:28,080 Speaker 1: about how the properties that are illustrated in the experiment 27 00:01:28,400 --> 00:01:31,679 Speaker 1: relate to you and how they relate you to the cosmos. 28 00:01:32,000 --> 00:01:33,680 Speaker 1: That's what's really going to be exciting about them is 29 00:01:33,720 --> 00:01:36,640 Speaker 1: that we kick off with something potentially a little explosive, 30 00:01:36,680 --> 00:01:39,280 Speaker 1: potentially a little goofy, and then we we try and 31 00:01:39,319 --> 00:01:41,959 Speaker 1: bring you to that wow moment. And we hope we 32 00:01:42,000 --> 00:01:43,600 Speaker 1: do this. We hope the kids really like it that 33 00:01:43,600 --> 00:01:46,360 Speaker 1: they don't throw tomatoes with their iPod screens. But I 34 00:01:46,360 --> 00:01:48,800 Speaker 1: think you know, if your parent watch them and you 35 00:01:48,800 --> 00:01:51,120 Speaker 1: can cheat, you can watch it on your own time 36 00:01:51,160 --> 00:01:52,840 Speaker 1: and then pretend that you knew all this when you 37 00:01:52,880 --> 00:01:55,120 Speaker 1: do the experiment with your kid. We don't mind. So 38 00:01:55,200 --> 00:01:57,080 Speaker 1: we thought we would take some of the elements that 39 00:01:57,120 --> 00:02:00,600 Speaker 1: we talked about and and bring them to you. Guys thought, well, 40 00:02:00,720 --> 00:02:03,400 Speaker 1: this is interesting stuff, like you know, what about roinbows 41 00:02:03,560 --> 00:02:06,520 Speaker 1: and why is the sky blue? And what about the 42 00:02:06,520 --> 00:02:09,760 Speaker 1: aurora borealis and all the other weird things that happens 43 00:02:09,800 --> 00:02:14,880 Speaker 1: with light and uh, liquids and refraction. Yeah, I mean, 44 00:02:15,000 --> 00:02:16,919 Speaker 1: all this information is just gonna drain out out of 45 00:02:16,919 --> 00:02:18,760 Speaker 1: our brains anyway, So as long as it's up there, 46 00:02:18,919 --> 00:02:21,120 Speaker 1: we might as well throw it out a podcast. It 47 00:02:21,200 --> 00:02:25,120 Speaker 1: is fascinating information because we're dealing with On one level, 48 00:02:25,600 --> 00:02:27,200 Speaker 1: we live in a world of light. We have our 49 00:02:27,240 --> 00:02:30,240 Speaker 1: sun beaming all this light to the earth. Light is 50 00:02:30,280 --> 00:02:33,320 Speaker 1: the means by which we visually sense the world around us. 51 00:02:33,440 --> 00:02:35,760 Speaker 1: But everything is not quite what it seems. We perceive 52 00:02:35,840 --> 00:02:38,360 Speaker 1: things in a certain way and then we end up 53 00:02:38,720 --> 00:02:42,200 Speaker 1: accepting that that is reality. But there are a number 54 00:02:42,200 --> 00:02:44,240 Speaker 1: of ways that we can sort of see through the 55 00:02:44,280 --> 00:02:47,360 Speaker 1: behaviors of light and gain a little more insight exactly 56 00:02:47,360 --> 00:02:49,120 Speaker 1: what's going on. But before we do that, I want 57 00:02:49,120 --> 00:02:51,720 Speaker 1: to talk about sunlight itself, because you know, we all 58 00:02:51,720 --> 00:02:53,799 Speaker 1: take it for granted. It's beaming down gives us a 59 00:02:53,880 --> 00:02:58,720 Speaker 1: nice sunburn or I don't know, warms up sunburn. Yeah, yeah, 60 00:02:58,840 --> 00:03:02,040 Speaker 1: warms us up on the cold day. Um okay, yeah, 61 00:03:02,040 --> 00:03:03,919 Speaker 1: it's not the seventies. It doesn't really give us a 62 00:03:04,000 --> 00:03:07,360 Speaker 1: nice sunburn. Hopefully it doesn't. I think that we should 63 00:03:07,400 --> 00:03:10,960 Speaker 1: talk about the photons and how they emerge from the sun. Right, 64 00:03:11,000 --> 00:03:13,240 Speaker 1: what we think of light, or it's easy to think 65 00:03:13,280 --> 00:03:15,880 Speaker 1: of light is instantaneous, you know, you flip in the 66 00:03:16,000 --> 00:03:19,360 Speaker 1: light switch and then light is there. But sunlight is 67 00:03:19,400 --> 00:03:22,480 Speaker 1: traveling from the Sun to the Earth. These photons that 68 00:03:22,560 --> 00:03:25,799 Speaker 1: make up light are traveling through space and they are 69 00:03:25,840 --> 00:03:28,880 Speaker 1: bombarding us, bouncing off of us. In fact, when they 70 00:03:28,919 --> 00:03:31,440 Speaker 1: hit us. It turns out that we know how long 71 00:03:31,480 --> 00:03:34,160 Speaker 1: it takes for the stream of light to actually hit 72 00:03:34,200 --> 00:03:36,040 Speaker 1: the Earth. We know this because we know the distance 73 00:03:36,080 --> 00:03:38,040 Speaker 1: from the Earth to the Sun. We know the speed 74 00:03:38,040 --> 00:03:40,840 Speaker 1: of light, so it only takes eight minutes and twenty 75 00:03:40,840 --> 00:03:44,240 Speaker 1: seconds for us to reach us after traveling what ninety 76 00:03:44,480 --> 00:03:47,880 Speaker 1: million miles or something. But I think it is absolutely fascinating. 77 00:03:48,440 --> 00:03:50,080 Speaker 1: So so if you were to turn the sun off, 78 00:03:50,160 --> 00:03:52,320 Speaker 1: it would be eight minutes before you'd really get the 79 00:03:52,360 --> 00:03:54,600 Speaker 1: idea that, whoa, the sun is off, because now the 80 00:03:54,680 --> 00:03:56,320 Speaker 1: light is run out. Yeah, yeah, you'd have a slight 81 00:03:56,360 --> 00:04:00,000 Speaker 1: delay there, right uh, And it would be terrifying. Who 82 00:04:00,000 --> 00:04:02,960 Speaker 1: in the sun off? But here's a really cool thing too, 83 00:04:03,320 --> 00:04:07,320 Speaker 1: that those photons are actually kicking around in the sun 84 00:04:07,640 --> 00:04:10,280 Speaker 1: for about me There are different accounts on this, but 85 00:04:10,320 --> 00:04:13,680 Speaker 1: anywhere from like ten thousand years to you know, twenty 86 00:04:13,760 --> 00:04:16,640 Speaker 1: thousand years before they get to emerge to the surface 87 00:04:16,720 --> 00:04:19,000 Speaker 1: of the Sun and then make that eight minute and 88 00:04:19,040 --> 00:04:21,559 Speaker 1: twenty second journey. And the reason for that is because 89 00:04:21,560 --> 00:04:24,359 Speaker 1: when a photon is in the center of the Sun, 90 00:04:24,760 --> 00:04:30,080 Speaker 1: it's just sort of getting pinball machined around, reabsorbed, emitted, reabsorbed, admitted, 91 00:04:30,080 --> 00:04:32,720 Speaker 1: reabsorbed admitted. So you know that when that photon gets 92 00:04:32,760 --> 00:04:35,080 Speaker 1: the surface, it's like, oh, finally, Yeah, it's like it's 93 00:04:35,080 --> 00:04:36,599 Speaker 1: in the sun. It's kind of like a like a 94 00:04:36,640 --> 00:04:38,800 Speaker 1: boxer before match in the back, just kind of like 95 00:04:38,839 --> 00:04:40,440 Speaker 1: punch in the air, you know, doing a little shadow 96 00:04:40,480 --> 00:04:42,240 Speaker 1: box and like, let's do this, getting pumped up and 97 00:04:42,240 --> 00:04:45,760 Speaker 1: then wham, finally, after after this immense amount of time, 98 00:04:46,040 --> 00:04:49,240 Speaker 1: launched towards the Earth, rips through the atmosphere and then 99 00:04:49,320 --> 00:04:51,520 Speaker 1: slams into like a little solar power on top of 100 00:04:51,520 --> 00:04:53,840 Speaker 1: one of those plastic squirrels that you see people put 101 00:04:53,920 --> 00:04:57,720 Speaker 1: their their lawn that glow and photo that and now 102 00:04:57,760 --> 00:04:59,680 Speaker 1: the journey is ended. Yeah, and then they probably talk 103 00:04:59,720 --> 00:05:01,839 Speaker 1: about all those years I powered the heck out of 104 00:05:01,839 --> 00:05:04,880 Speaker 1: that squirrel. What where I'm gonna end up squirrel, a 105 00:05:05,880 --> 00:05:08,120 Speaker 1: sellar squirrel. But anyway, we thought that was kind of 106 00:05:08,120 --> 00:05:09,800 Speaker 1: cool to share with you guys, and we thought that 107 00:05:09,839 --> 00:05:12,400 Speaker 1: would help to talk a little bit more about these 108 00:05:12,400 --> 00:05:16,640 Speaker 1: other what seemed like optical illusions, rainbows and our blue 109 00:05:16,640 --> 00:05:19,400 Speaker 1: sky above. Well, let's get into rainbows. A scientist by 110 00:05:19,400 --> 00:05:22,240 Speaker 1: the name of Kermit T. Frog once the rainbows or 111 00:05:22,400 --> 00:05:25,719 Speaker 1: visions but only illusions, and rainbows have nothing to hide. 112 00:05:25,720 --> 00:05:27,800 Speaker 1: Do rainbows really have nothing to hide? That pot of 113 00:05:27,839 --> 00:05:29,920 Speaker 1: gold I've yet to find it. Well, yes, that's true. 114 00:05:29,920 --> 00:05:33,080 Speaker 1: And we were discussing earlier if rainbows really did rise 115 00:05:33,120 --> 00:05:34,640 Speaker 1: from a pot of gold, does that mean there are 116 00:05:34,640 --> 00:05:37,320 Speaker 1: two pots of gold, two pots of lepricn gold on 117 00:05:37,360 --> 00:05:40,760 Speaker 1: the earth at any given time to facilitate rainbow. And 118 00:05:40,800 --> 00:05:43,320 Speaker 1: if there's only one pot of gold, the rainbow can't 119 00:05:43,600 --> 00:05:46,039 Speaker 1: have two in here. Here's where I'm gonna shatter that 120 00:05:46,200 --> 00:05:50,400 Speaker 1: the pot of gold question for you all together. Rainbows 121 00:05:50,400 --> 00:05:53,359 Speaker 1: actually appear as halos, not these sort of half arcs 122 00:05:53,360 --> 00:05:56,719 Speaker 1: that we see. Yeah. Yeah, so if you were to 123 00:05:56,800 --> 00:05:59,000 Speaker 1: go above the clouds and look down, you would see 124 00:05:59,680 --> 00:06:03,080 Speaker 1: that rainbow is actually a halo, a circle, a giant one, 125 00:06:03,200 --> 00:06:05,480 Speaker 1: and when we're here in the ground we look up 126 00:06:05,560 --> 00:06:08,760 Speaker 1: the horizon, we're only seeing a portion of that because 127 00:06:08,760 --> 00:06:11,239 Speaker 1: of course we don't have, first of all, the inner 128 00:06:11,279 --> 00:06:14,280 Speaker 1: machinery to try to perceive that, and sort of the 129 00:06:14,320 --> 00:06:17,320 Speaker 1: Earth is kind of in our way, blocking our view 130 00:06:17,360 --> 00:06:21,000 Speaker 1: of that entire halo. You know, occasionally will you'll even 131 00:06:21,000 --> 00:06:24,400 Speaker 1: see an inverted rainbow. Were aware of this. I've heard 132 00:06:24,400 --> 00:06:27,400 Speaker 1: of this. It's crazy, and it's caused by sunlight shining 133 00:06:27,440 --> 00:06:32,240 Speaker 1: through atmospheric ice crystals. It's rarely encountered. At latitudes far 134 00:06:32,320 --> 00:06:35,320 Speaker 1: from the Earth's poles, we have these upside down rainbows 135 00:06:35,560 --> 00:06:37,800 Speaker 1: where the sunlight shines through these tiny ice crystals too 136 00:06:37,839 --> 00:06:40,800 Speaker 1: high altitude clouds, and it creates this. I guess you 137 00:06:40,800 --> 00:06:42,400 Speaker 1: think of it as like a smiley face. It's turning 138 00:06:42,440 --> 00:06:45,160 Speaker 1: the frown at the rainbow upside down. It's beautiful. It is. 139 00:06:45,880 --> 00:06:49,599 Speaker 1: Let's talk about this process. This bending of light, or 140 00:06:50,120 --> 00:06:52,679 Speaker 1: as you have referred to it before, is shattering white 141 00:06:52,760 --> 00:06:55,279 Speaker 1: light seeing what it's made of. So think of it 142 00:06:55,279 --> 00:06:59,159 Speaker 1: this way. White light is a lie and and the 143 00:06:59,240 --> 00:07:03,000 Speaker 1: raindrop or a prism or any kind of prism like device, 144 00:07:03,279 --> 00:07:05,560 Speaker 1: it takes that white light and it breaks it up. 145 00:07:06,000 --> 00:07:08,520 Speaker 1: We're breaking it up with with some droplets and turning 146 00:07:08,520 --> 00:07:12,440 Speaker 1: it into the seven different wavelengths and make it up right. 147 00:07:12,480 --> 00:07:14,440 Speaker 1: So there are seven components of light and you may 148 00:07:14,560 --> 00:07:17,280 Speaker 1: know them as roy g BIV. You probably learned that 149 00:07:17,280 --> 00:07:21,000 Speaker 1: in school. Red, orange, yellow, green, blue, indigo, and violet. 150 00:07:21,120 --> 00:07:23,960 Speaker 1: And they all have different wavelengths. So when they've bend, 151 00:07:24,080 --> 00:07:27,280 Speaker 1: they all kind of behave differently, and you've got red 152 00:07:27,520 --> 00:07:31,600 Speaker 1: right and violet book ending the colors and rainbow and 153 00:07:31,680 --> 00:07:34,000 Speaker 1: red is the strongest while violet is just a it's 154 00:07:34,000 --> 00:07:36,520 Speaker 1: a little bit hazier. Okay. I was that roy g 155 00:07:36,600 --> 00:07:40,360 Speaker 1: BIV would be a good name for a leprechn too. Yeah. 156 00:07:40,400 --> 00:07:43,960 Speaker 1: I can see it on his little outfit like his 157 00:07:44,160 --> 00:07:47,240 Speaker 1: like his his name tag, like he's a convention. Yeah, 158 00:07:47,360 --> 00:07:50,679 Speaker 1: I'm sure it's been done. There's also a really great 159 00:07:50,760 --> 00:07:55,080 Speaker 1: Boards of Canada track called roy g BIV. There. So 160 00:07:55,160 --> 00:07:57,080 Speaker 1: think about that. You think about that prism. You think 161 00:07:57,080 --> 00:07:59,520 Speaker 1: about this rain drops up in the sky acting as 162 00:07:59,600 --> 00:08:03,600 Speaker 1: tiny prisms and refracting that light. And then you know 163 00:08:03,680 --> 00:08:06,720 Speaker 1: that light bouncing off the side of that rain drop 164 00:08:07,120 --> 00:08:11,280 Speaker 1: and then further refracting it and reflecting it. And that's 165 00:08:11,280 --> 00:08:14,360 Speaker 1: why you get this like incredibly cool vision in the sky. 166 00:08:14,560 --> 00:08:17,760 Speaker 1: You know what, other skies may have rainbows in our 167 00:08:17,800 --> 00:08:21,840 Speaker 1: solar system. What if you traveled to Saturn's moon Titan, 168 00:08:22,000 --> 00:08:24,080 Speaker 1: scientists think you might be able to see a rainbow 169 00:08:24,120 --> 00:08:27,640 Speaker 1: because it boths both sunlight and water droplets. So it 170 00:08:27,680 --> 00:08:30,080 Speaker 1: could happen, we can hear. Yeah, yeah, So if you 171 00:08:30,080 --> 00:08:34,920 Speaker 1: travel to Titan, keep a lookout. Okay, so that gives 172 00:08:34,960 --> 00:08:37,719 Speaker 1: us some insight into rainbows. When we come back from 173 00:08:37,720 --> 00:08:40,440 Speaker 1: our break, we're going to ask the question why is 174 00:08:40,440 --> 00:08:47,680 Speaker 1: the sky blue? And we're back, why is it the 175 00:08:47,679 --> 00:08:50,400 Speaker 1: sky blue? I believe it was the magician comedian Night 176 00:08:50,440 --> 00:08:53,559 Speaker 1: Court star Harry Anderson who answered this question by saying, 177 00:08:53,760 --> 00:08:55,959 Speaker 1: if the sky were green, we wouldn't know when to 178 00:08:56,000 --> 00:08:59,720 Speaker 1: stop mowing. That's right, which is a valid commentary on 179 00:09:00,080 --> 00:09:02,800 Speaker 1: the optical world. But it's it's actually a little more 180 00:09:02,840 --> 00:09:05,400 Speaker 1: complicated than that. The reason that the sky is blue 181 00:09:05,600 --> 00:09:10,719 Speaker 1: relates right back to these different wavelengths in light. That's right. 182 00:09:10,920 --> 00:09:15,640 Speaker 1: So atoms, molecules and particles and atmosphere absorb and scatter light. Okay, 183 00:09:15,720 --> 00:09:18,480 Speaker 1: so we're going to talk not specifically like we were 184 00:09:18,559 --> 00:09:21,079 Speaker 1: with the rainbow, but we're talking about that huge expanse 185 00:09:21,160 --> 00:09:24,400 Speaker 1: of blue sky above us. And again we're talking about 186 00:09:24,400 --> 00:09:27,679 Speaker 1: the components of light roy g biv and those different 187 00:09:27,720 --> 00:09:31,960 Speaker 1: wavelengths that scattered throughout the atmosphere, which means that some 188 00:09:32,080 --> 00:09:35,360 Speaker 1: are better spotted by our eyes than others, and this 189 00:09:35,440 --> 00:09:40,360 Speaker 1: is called Raleigh scattering. Shorter wavelengths like blue and violet 190 00:09:40,440 --> 00:09:43,800 Speaker 1: actually scatter a lot more than long ones when particles 191 00:09:43,800 --> 00:09:48,000 Speaker 1: like oxygen and nitrogen molecules are relatively small. Okay, so 192 00:09:48,120 --> 00:09:52,800 Speaker 1: that's why blue and violet are pretty much dominating the 193 00:09:52,880 --> 00:09:55,120 Speaker 1: sky for us, because that's what we're perceiving. It's what 194 00:09:55,240 --> 00:09:59,280 Speaker 1: scatters throughout that atmosphere. But I mean, you probably are 195 00:09:59,200 --> 00:10:01,360 Speaker 1: asking the question, if that's the case, then why don't 196 00:10:01,360 --> 00:10:03,280 Speaker 1: I look up at a sky that's all sort of 197 00:10:03,360 --> 00:10:06,240 Speaker 1: monet you know, blue and purple splot Why do I 198 00:10:06,320 --> 00:10:09,120 Speaker 1: get that one color? And it comes down to the 199 00:10:09,160 --> 00:10:11,480 Speaker 1: limits of our our eyes and the limits of our 200 00:10:11,480 --> 00:10:14,120 Speaker 1: brain to process all of this information. Yeah, because the 201 00:10:14,160 --> 00:10:17,400 Speaker 1: cones in our eye seen overlap in these two colors. 202 00:10:17,679 --> 00:10:20,559 Speaker 1: I mean, it's really again limitations of machinery that we have. 203 00:10:21,120 --> 00:10:23,360 Speaker 1: So it's sort of like our eyes are interpreting this 204 00:10:23,520 --> 00:10:26,920 Speaker 1: information for us. And saying, Okay, this must be this 205 00:10:27,000 --> 00:10:31,640 Speaker 1: one color blue. And I love this idea that almost 206 00:10:31,679 --> 00:10:35,560 Speaker 1: within our brain we have a painter mixing these colors, 207 00:10:35,840 --> 00:10:39,000 Speaker 1: the blue and the purple and white and coming up 208 00:10:39,040 --> 00:10:41,719 Speaker 1: with this blue sky for us. Yeah, that's kind of 209 00:10:41,760 --> 00:10:44,880 Speaker 1: simplifying the process. It's like, what do we have coming in, Well, 210 00:10:44,880 --> 00:10:47,040 Speaker 1: there's a little violet. We're just gonna call it blue, 211 00:10:47,160 --> 00:10:49,640 Speaker 1: you know, simplify things. We've got enough to worry about. 212 00:10:49,720 --> 00:10:52,640 Speaker 1: Since wise we're not about the sky. It's really not 213 00:10:52,720 --> 00:10:54,600 Speaker 1: doing much for you. Yeah, this brain is taking up 214 00:10:54,600 --> 00:10:57,320 Speaker 1: a lot of energy as it is. Let's just say blue. 215 00:10:58,000 --> 00:11:00,000 Speaker 1: And then it's so cool to think that every single 216 00:11:00,120 --> 00:11:03,040 Speaker 1: day you get a different shade of this this painterly blue, 217 00:11:03,080 --> 00:11:06,040 Speaker 1: depending on how cloudy is, how much sun there is. 218 00:11:07,000 --> 00:11:09,720 Speaker 1: I find it fascinating. I remember always finding like a 219 00:11:09,760 --> 00:11:12,319 Speaker 1: really blue sky kind of depressing, Like I'm more of 220 00:11:12,360 --> 00:11:15,599 Speaker 1: a cloud guy, like a like a nice cloudy overcast day, 221 00:11:15,760 --> 00:11:17,959 Speaker 1: or even if it's I mean, I like sunlight as 222 00:11:18,040 --> 00:11:20,440 Speaker 1: much of the next guy, and my body needs it. 223 00:11:20,679 --> 00:11:22,120 Speaker 1: But even then I like, I like a sun with 224 00:11:22,160 --> 00:11:24,840 Speaker 1: a little clouds mixing it up, but like a really 225 00:11:25,840 --> 00:11:30,160 Speaker 1: endlessly blue monotonously blue sky is there's something just kind 226 00:11:30,160 --> 00:11:32,920 Speaker 1: of weighs on you. Okay, here's the weird thing, Robert Lamb, 227 00:11:33,520 --> 00:11:37,000 Speaker 1: you wear blue all the time, sky blue. In fact, 228 00:11:37,000 --> 00:11:38,880 Speaker 1: you're wearing it right now. You don't wear the same 229 00:11:38,880 --> 00:11:41,080 Speaker 1: blue shirt every day, but you have like ten of 230 00:11:41,160 --> 00:11:44,440 Speaker 1: that was that verious shell. Yeah, well that's a color 231 00:11:44,440 --> 00:11:46,319 Speaker 1: that looks good at me, I'm told by my wife. 232 00:11:46,360 --> 00:11:49,440 Speaker 1: So but but or maybe that's the thing. Maybe I 233 00:11:49,720 --> 00:11:52,160 Speaker 1: since I wear blue a lot, I'm a little concerned 234 00:11:52,200 --> 00:11:55,160 Speaker 1: when the sky is dressed the same as me. You're 235 00:11:55,200 --> 00:11:57,959 Speaker 1: afraid that someone's gonna a bird, is gonna mistake you 236 00:11:58,000 --> 00:12:00,360 Speaker 1: for this guy, or they just look at that guy. 237 00:12:00,440 --> 00:12:02,240 Speaker 1: He's in the sky addressed the same. They're just a 238 00:12:02,280 --> 00:12:06,240 Speaker 1: couple of twinkies. Alright. So one other quickie for you guys. 239 00:12:06,520 --> 00:12:11,880 Speaker 1: Northern lights of those are those dazzling Arctic and Antarctic displays, 240 00:12:12,360 --> 00:12:16,080 Speaker 1: colorful sheets of light transforming the endless winter skies. Right. Yeah. 241 00:12:16,120 --> 00:12:19,079 Speaker 1: If you catch any of the Discovery BBC co production 242 00:12:19,760 --> 00:12:22,840 Speaker 1: Frozen Planet, there's an episode that deals with the northern 243 00:12:22,920 --> 00:12:25,800 Speaker 1: lights and they use some time laps stuff and just 244 00:12:25,960 --> 00:12:29,640 Speaker 1: fabulous filmography to capture the Northern lights, so definitely check 245 00:12:29,679 --> 00:12:32,000 Speaker 1: that out of you for a visual interpretation of what 246 00:12:32,040 --> 00:12:35,319 Speaker 1: we're talking about. Yeah, and these actually form when solar 247 00:12:35,320 --> 00:12:38,320 Speaker 1: particles are thrown out by explosions on the Sun and 248 00:12:38,360 --> 00:12:41,560 Speaker 1: are drawn by the Earth's magnetic field toward the North 249 00:12:41,600 --> 00:12:46,480 Speaker 1: and South Poles, colliding with atmospheric gases to emit photons 250 00:12:46,640 --> 00:12:50,040 Speaker 1: or light particles. And I just found that pretty cool 251 00:12:50,120 --> 00:12:53,920 Speaker 1: to be recently talked about magnets, magnetic fields North and 252 00:12:53,960 --> 00:12:56,280 Speaker 1: South Pole and how all of this sort of helps 253 00:12:56,360 --> 00:12:58,920 Speaker 1: us to not be bombarded by all of the Sun's 254 00:12:58,960 --> 00:13:02,160 Speaker 1: solar junk. But it's very cool to know that it's 255 00:13:02,160 --> 00:13:05,439 Speaker 1: also part of this again, paint release guy in some 256 00:13:05,520 --> 00:13:08,040 Speaker 1: climes of the world. What is kind of sad about 257 00:13:08,080 --> 00:13:10,440 Speaker 1: the Northern lights is that my family, when I was younger, 258 00:13:10,480 --> 00:13:11,960 Speaker 1: we lived in Canada for a little bit. I think 259 00:13:11,960 --> 00:13:14,160 Speaker 1: I mentioned before. We my dad was a dentist up 260 00:13:14,200 --> 00:13:17,080 Speaker 1: in Newfoundland, Canada, so it's pretty far north, and I 261 00:13:17,160 --> 00:13:19,560 Speaker 1: know on at least one occasion, like we went out 262 00:13:19,600 --> 00:13:22,439 Speaker 1: and made a special trip to glimpse the Northern lights 263 00:13:23,120 --> 00:13:25,400 Speaker 1: and supposedly we saw them, but it didn't really make 264 00:13:25,440 --> 00:13:27,120 Speaker 1: I was like in kindergarten at the time, and it 265 00:13:27,160 --> 00:13:29,240 Speaker 1: didn't make a real impression on me, and I don't 266 00:13:29,280 --> 00:13:31,080 Speaker 1: really have a firm memory of what they may have 267 00:13:31,120 --> 00:13:34,000 Speaker 1: looked like. So I've always done that kind of sad 268 00:13:34,040 --> 00:13:35,240 Speaker 1: because people are like, oh, did you get to see 269 00:13:35,240 --> 00:13:37,880 Speaker 1: the Northern Lights? Like, yeah, I did, And what do 270 00:13:37,880 --> 00:13:39,920 Speaker 1: you think I didn't make an impression. I think you 271 00:13:39,920 --> 00:13:42,720 Speaker 1: need to implant a memory there well, to a certain extent, 272 00:13:42,800 --> 00:13:45,079 Speaker 1: I do you know, And this of course we've done 273 00:13:45,080 --> 00:13:47,520 Speaker 1: all podcasts about memory. But but then I your stories 274 00:13:47,559 --> 00:13:49,440 Speaker 1: about us going to see the Northern Lights. So I 275 00:13:49,480 --> 00:13:52,719 Speaker 1: create this vision of my family standing there, and then 276 00:13:52,760 --> 00:13:55,600 Speaker 1: I see these brilliant time laps videos of the Northern Lights, 277 00:13:55,600 --> 00:13:57,640 Speaker 1: so I kind of throw that in there, and then 278 00:13:57,679 --> 00:14:00,400 Speaker 1: I throw this vision of me justlike standing around day dreaming, 279 00:14:00,400 --> 00:14:02,520 Speaker 1: looking at the ground instead of looking up at the 280 00:14:02,559 --> 00:14:05,080 Speaker 1: brilliance in the heavens. Again, that's the thing that I 281 00:14:05,120 --> 00:14:08,360 Speaker 1: find fascinating, is this idea that our brain is interpreting 282 00:14:08,360 --> 00:14:11,480 Speaker 1: the information that we see and it's not really the 283 00:14:11,559 --> 00:14:14,120 Speaker 1: reality always, right, You've got memory, and then you just 284 00:14:14,160 --> 00:14:17,240 Speaker 1: have the limitations of what we've been given or what 285 00:14:17,360 --> 00:14:21,000 Speaker 1: we have evolved with. And so yeah, I mean this 286 00:14:21,120 --> 00:14:25,280 Speaker 1: guy isn't necessarily blue. There's another quick rainbow. In fact, 287 00:14:25,600 --> 00:14:29,240 Speaker 1: the Babylonian goddess Ishtar wears rainbows is kind of a 288 00:14:29,240 --> 00:14:33,400 Speaker 1: fancy necklace and there's a light off. Yeah, and there's 289 00:14:33,400 --> 00:14:36,200 Speaker 1: a delightful rainbow bridge that connects the Norse realms of 290 00:14:36,280 --> 00:14:39,240 Speaker 1: Vascard and mid Guard, which I think they do something 291 00:14:39,240 --> 00:14:40,760 Speaker 1: with that in the Thor comic books in the Thor 292 00:14:40,920 --> 00:14:42,840 Speaker 1: movie as well. You have to take down some of 293 00:14:42,840 --> 00:14:46,280 Speaker 1: that masculine energy there. What a rainbows about? That's what 294 00:14:46,400 --> 00:14:48,480 Speaker 1: we ride our horses over when we trawl up into war, 295 00:14:49,400 --> 00:14:52,240 Speaker 1: trall up into war. I don't know what I'm saying anymore. Uh, well, 296 00:14:52,280 --> 00:14:53,880 Speaker 1: you know what. That's what happens when you do you 297 00:14:53,960 --> 00:14:56,040 Speaker 1: tend videos back to back. Okay, this is some of 298 00:14:56,080 --> 00:14:57,920 Speaker 1: the stuff that we learned, and we may continue to 299 00:14:57,920 --> 00:15:00,480 Speaker 1: bring some other items that we covered as well to 300 00:15:00,560 --> 00:15:03,840 Speaker 1: you guys, but have a lookout for these videos. Also 301 00:15:03,880 --> 00:15:07,440 Speaker 1: wanted to mention that Matt Frederick, our producer here, created 302 00:15:07,480 --> 00:15:09,720 Speaker 1: the music for that and it's really cool indeed, so 303 00:15:09,800 --> 00:15:11,440 Speaker 1: Keeop a look out for those. We'll throw some links 304 00:15:11,440 --> 00:15:13,360 Speaker 1: stuff on the Facebook and the Twitter for sure, so 305 00:15:13,400 --> 00:15:15,280 Speaker 1: that you can view these and show them to your 306 00:15:15,360 --> 00:15:17,800 Speaker 1: kids yourself. Let's call the robot over give us some 307 00:15:17,880 --> 00:15:23,000 Speaker 1: of that sweet listener mail. Here's one from Madeline. Madeline 308 00:15:23,080 --> 00:15:25,640 Speaker 1: rights and says, Hey, Robert and Julie. Just thought I 309 00:15:25,680 --> 00:15:27,720 Speaker 1: would say thanks for all the great podcast I've been 310 00:15:27,720 --> 00:15:30,040 Speaker 1: listening to them and really enjoying them for a while now, 311 00:15:30,120 --> 00:15:31,600 Speaker 1: and I thought it should finally take the time to 312 00:15:31,600 --> 00:15:34,920 Speaker 1: say thanks. I think you guys pick great topics, always 313 00:15:35,040 --> 00:15:38,040 Speaker 1: very interesting and fun. You two can also be quite funny. 314 00:15:38,240 --> 00:15:40,080 Speaker 1: You made me laugh a lot. I like the random 315 00:15:40,120 --> 00:15:43,320 Speaker 1: bits of personal stories and et cetera that sometimes are 316 00:15:43,400 --> 00:15:46,360 Speaker 1: in your podcast. To you both seem very cool. I'm 317 00:15:46,360 --> 00:15:48,920 Speaker 1: a sixteen year old girl from Michigan. Hey, that's uh 318 00:15:49,080 --> 00:15:53,720 Speaker 1: your homestake. I found your podcast on the Zoom marketplace 319 00:15:53,760 --> 00:15:55,840 Speaker 1: a long time ago and have been enjoying them ever since. 320 00:15:56,240 --> 00:15:59,440 Speaker 1: I liked you guys on Facebook. Just now, oh there 321 00:15:59,440 --> 00:16:02,600 Speaker 1: he goes, Just watch the register. Um. I love your photos. 322 00:16:02,640 --> 00:16:04,480 Speaker 1: It's funny to see the faces of people I've been 323 00:16:04,520 --> 00:16:09,240 Speaker 1: listening to for months. You both look great this. I 324 00:16:09,280 --> 00:16:11,000 Speaker 1: hope you guys keep up with great work. I learned 325 00:16:11,000 --> 00:16:14,000 Speaker 1: a lot of interesting stuff listening to your podcast. I'm 326 00:16:14,000 --> 00:16:16,440 Speaker 1: often thinking about it in the boring moments of school 327 00:16:16,560 --> 00:16:20,240 Speaker 1: for days after. Thanks a lot, Matline, very cool, Thanks 328 00:16:20,240 --> 00:16:22,520 Speaker 1: for listening, Melan.
