1 00:00:01,040 --> 00:00:04,120 Speaker 1: Good afternoon, and welcome to Stuff you Should Know Selects. 2 00:00:04,600 --> 00:00:06,520 Speaker 1: It is Charles W. Chuck Bryant here in. My pick 3 00:00:06,600 --> 00:00:10,119 Speaker 1: for this week is How Mirrors Work from September fourteen, 4 00:00:10,480 --> 00:00:13,960 Speaker 1: two thousand ten. And boy, this one was a tough one. 5 00:00:14,200 --> 00:00:16,560 Speaker 1: I remember when we had the idea of doing a 6 00:00:16,560 --> 00:00:18,799 Speaker 1: show on mirrors. I thought, well, that's going to be 7 00:00:18,800 --> 00:00:21,840 Speaker 1: short and not so interesting. But then I thought, oh, 8 00:00:21,840 --> 00:00:24,880 Speaker 1: wait a minute, how do mirrors work? How are those 9 00:00:24,920 --> 00:00:28,320 Speaker 1: things made? Where did they come from? It's pretty amazing. 10 00:00:28,400 --> 00:00:31,840 Speaker 1: So we get into all that and more, and it's 11 00:00:31,880 --> 00:00:34,600 Speaker 1: a pretty fascinating episode. And this will be one where 12 00:00:34,640 --> 00:00:36,480 Speaker 1: you can kind of whip out some of these facts 13 00:00:36,720 --> 00:00:39,479 Speaker 1: at your next dinner party and amazing to light your 14 00:00:39,479 --> 00:00:42,720 Speaker 1: friends and family. So enjoy How Mirrors Work right here, 15 00:00:42,840 --> 00:00:54,760 Speaker 1: right now. Welcome to Stuff you Should Know from House 16 00:00:54,760 --> 00:01:03,440 Speaker 1: Stuff Works dot com. Hey, and welcome to the podcast. 17 00:01:03,720 --> 00:01:07,280 Speaker 1: I'm Josh Clark, there's Charles W. Chuck Bryant. We're about 18 00:01:07,319 --> 00:01:10,960 Speaker 1: to talk about mirrors. I set up it's a sinct 19 00:01:11,840 --> 00:01:13,960 Speaker 1: how are you were you in the mirrors growing up? 20 00:01:14,080 --> 00:01:16,640 Speaker 1: Now that we said, you know, I did it scinctly, 21 00:01:16,640 --> 00:01:21,319 Speaker 1: we're gonna just blow like three minutes right. No, I 22 00:01:21,319 --> 00:01:23,120 Speaker 1: was asking you if you were into mirrors, in the 23 00:01:23,240 --> 00:01:25,800 Speaker 1: mirrors growing up? Yeah, I mean that didn't every kid 24 00:01:25,840 --> 00:01:28,240 Speaker 1: go through a phase where they're like very obsessed with 25 00:01:28,280 --> 00:01:30,640 Speaker 1: their looks and mirrors and things. Oh yeah, I was 26 00:01:30,680 --> 00:01:32,920 Speaker 1: into myself. I wasn't in the mirrors. They were just 27 00:01:33,319 --> 00:01:36,319 Speaker 1: a means and end, you know. Yeah, But I like 28 00:01:36,360 --> 00:01:37,720 Speaker 1: I was reading this and I kind of was just 29 00:01:37,760 --> 00:01:40,440 Speaker 1: thinking myself and remembering laughing about I remember being like 30 00:01:40,480 --> 00:01:43,759 Speaker 1: fifteen and like stopping to look at mirrors anytime there 31 00:01:43,840 --> 00:01:46,360 Speaker 1: was one to what looked like Yeah, and now I 32 00:01:46,440 --> 00:01:49,200 Speaker 1: just I break them. I'd forgotten all about that phase 33 00:01:49,240 --> 00:01:51,040 Speaker 1: of my life though, until you just brought it up. 34 00:01:51,240 --> 00:01:54,120 Speaker 1: Remember that. Yeah, it's nice to be able to not 35 00:01:54,280 --> 00:01:56,240 Speaker 1: look at a mirror. Like some days I'll go out, 36 00:01:56,920 --> 00:01:58,960 Speaker 1: you know, after getting ready in the morning, and I 37 00:01:59,000 --> 00:02:02,000 Speaker 1: have no idea what I actually look like. But I'm 38 00:02:02,080 --> 00:02:04,880 Speaker 1: so And this is um this cross pollination with an 39 00:02:04,920 --> 00:02:09,760 Speaker 1: earlier podcast. I suffered from body dysmorphic disorder so badly 40 00:02:10,280 --> 00:02:12,440 Speaker 1: that I don't really know what I look like anyway. 41 00:02:12,600 --> 00:02:14,440 Speaker 1: What do you think you look like? I think I 42 00:02:14,560 --> 00:02:19,880 Speaker 1: look a bit like the top from Taxidermia. I what's 43 00:02:19,919 --> 00:02:24,679 Speaker 1: that it's not plusant? Okay, well you don't my friend. 44 00:02:24,680 --> 00:02:25,880 Speaker 1: I don't even know what he looks like, but I 45 00:02:25,919 --> 00:02:29,200 Speaker 1: can tell you don't look like him. I appreciate that, Chuck, Chuck, 46 00:02:29,720 --> 00:02:32,160 Speaker 1: do you want to hear what I had in store? Like? 47 00:02:32,200 --> 00:02:34,040 Speaker 1: I could not come up with an intro for this. 48 00:02:34,200 --> 00:02:40,079 Speaker 1: Let's hear it. Websters defines mirror. I'm kidding. I always 49 00:02:40,080 --> 00:02:42,440 Speaker 1: going to say something equally bad, though, It's going to 50 00:02:42,440 --> 00:02:46,760 Speaker 1: be something along the lines with mirrors are ubiquitous. I've 51 00:02:46,800 --> 00:02:50,840 Speaker 1: seen at least six of them today. They weren't always 52 00:02:50,840 --> 00:02:53,200 Speaker 1: that way, though, Chuck. Well, it says in the article 53 00:02:53,240 --> 00:02:56,880 Speaker 1: here the full length mirrors have only been around four years. 54 00:02:56,880 --> 00:02:59,919 Speaker 1: That didn't seem right. That's not right. No, um full 55 00:03:00,040 --> 00:03:03,520 Speaker 1: length mirrors. There is a type of full length mirror 56 00:03:03,720 --> 00:03:07,200 Speaker 1: um that has been around for about four years. Full 57 00:03:07,280 --> 00:03:09,880 Speaker 1: length mirrors, as far as I know, are mirrors capable 58 00:03:10,280 --> 00:03:13,359 Speaker 1: of reflecting a full image of a person, have been 59 00:03:13,400 --> 00:03:16,840 Speaker 1: around since about the first century A d actually um 60 00:03:16,919 --> 00:03:23,720 Speaker 1: and mirrors us using surfaces polished surfaces to see our 61 00:03:23,760 --> 00:03:29,560 Speaker 1: own reflection. Um has been around since about six thousand BC. Yeah, 62 00:03:29,639 --> 00:03:33,639 Speaker 1: the earliest ones were found in Anatolia, Turkey and they're 63 00:03:33,680 --> 00:03:37,600 Speaker 1: polished subsidian. Yeah, it's a volcanic glass. Yeah, so it's 64 00:03:37,640 --> 00:03:40,720 Speaker 1: it's dark, this interesting, but it's still produced the best reflection, 65 00:03:40,760 --> 00:03:42,720 Speaker 1: I guess at the time. At the time, yeah, I 66 00:03:42,760 --> 00:03:44,480 Speaker 1: mean you gotta you gotta go with what you what 67 00:03:44,600 --> 00:03:46,720 Speaker 1: we have to work with, right. Well yeah, but then 68 00:03:46,760 --> 00:03:50,160 Speaker 1: after that they led them to um like silver and 69 00:03:50,360 --> 00:03:54,400 Speaker 1: bronze and copper, polished polished reflections basically, And Chuck, I 70 00:03:54,440 --> 00:03:56,920 Speaker 1: don't know if you've ever held a hunk of of 71 00:03:57,040 --> 00:04:02,760 Speaker 1: copper or bronze I haven't, or silver I have. Okay, 72 00:04:02,760 --> 00:04:05,680 Speaker 1: it's heavy, Yeah, it's real heavy. Right. So this actually 73 00:04:05,720 --> 00:04:10,680 Speaker 1: limited the size of mirrors for centuries, right Yeah. And 74 00:04:10,680 --> 00:04:12,400 Speaker 1: they were just kind of decorative at first, two right, 75 00:04:12,960 --> 00:04:15,440 Speaker 1: I think so. And you also had to be extremely rich, 76 00:04:15,760 --> 00:04:19,400 Speaker 1: um to own one of these, right, um. And then 77 00:04:19,560 --> 00:04:23,520 Speaker 1: around I think the Middle Ages, we became capable of 78 00:04:23,520 --> 00:04:26,080 Speaker 1: making glass, and all of a sudden, it was like 79 00:04:26,200 --> 00:04:30,120 Speaker 1: mirror technology just takes a huge leap forward. Well true, 80 00:04:30,320 --> 00:04:34,640 Speaker 1: but not not super uh forward, because the sand was 81 00:04:34,920 --> 00:04:37,440 Speaker 1: pretty impure back then they used to make the glass. 82 00:04:37,480 --> 00:04:39,920 Speaker 1: So I think they, um they said in the article, 83 00:04:40,000 --> 00:04:42,400 Speaker 1: was until like the Renaissance that it kind of really 84 00:04:42,440 --> 00:04:46,000 Speaker 1: started becoming a little more polished, if you will, terrible. 85 00:04:46,120 --> 00:04:49,120 Speaker 1: And then the Venetians are who really you know with 86 00:04:49,160 --> 00:04:51,039 Speaker 1: a glass and everything. They just they just took in 87 00:04:51,120 --> 00:04:53,840 Speaker 1: ran with it. Well. Even still, if you successfully made 88 00:04:53,839 --> 00:04:58,800 Speaker 1: a mirror UM, it was probably extremely expensive as well 89 00:04:59,320 --> 00:05:02,560 Speaker 1: because they were so rare. The process of manufacturing a 90 00:05:02,640 --> 00:05:06,960 Speaker 1: mirror UM very infrequently produced a usable mirror. That's what 91 00:05:07,000 --> 00:05:15,280 Speaker 1: you're doing was adhering um melted molten metal onto glass, 92 00:05:15,560 --> 00:05:19,040 Speaker 1: which almost always broke the glass. So when it didn't, 93 00:05:19,080 --> 00:05:21,400 Speaker 1: I'm sure you're just like, oh my god's the first 94 00:05:21,400 --> 00:05:26,159 Speaker 1: one in seven years? Right? Um? But that when I 95 00:05:26,200 --> 00:05:28,039 Speaker 1: was reading this article, I didn't really think about it. 96 00:05:28,120 --> 00:05:30,600 Speaker 1: That's what a mirror is, isn't it. I've even seen 97 00:05:30,640 --> 00:05:33,760 Speaker 1: the back of mirrors and been like others like metal 98 00:05:34,080 --> 00:05:36,880 Speaker 1: looks like spray painted on the back. That's exactly right. 99 00:05:37,320 --> 00:05:39,799 Speaker 1: And that was a process um what's it called silver 100 00:05:39,920 --> 00:05:43,520 Speaker 1: ring that was invented by a guy named Justice von 101 00:05:43,640 --> 00:05:47,800 Speaker 1: Liebig and in eighteen thirty five, if he figured out 102 00:05:47,880 --> 00:05:52,280 Speaker 1: how to spray very thin layer of silver um or 103 00:05:52,320 --> 00:05:55,479 Speaker 1: aluminum on the back or on one side of a 104 00:05:55,640 --> 00:05:59,560 Speaker 1: glass and they're my friend. You have the modern mirror. Yeah, 105 00:05:59,600 --> 00:06:01,240 Speaker 1: and now that I think they make it now by 106 00:06:01,320 --> 00:06:04,080 Speaker 1: heating aluminum in a vacuum in kind of much the 107 00:06:04,120 --> 00:06:07,240 Speaker 1: same way or different methods, but the same same concept. 108 00:06:08,680 --> 00:06:11,560 Speaker 1: Go ahead, Well, I wanted to say when when you 109 00:06:11,600 --> 00:06:15,680 Speaker 1: were talking about the Renaissance, the Venetians were they, I 110 00:06:15,720 --> 00:06:19,159 Speaker 1: guess they had the secret of mirrors under wraps like 111 00:06:19,200 --> 00:06:23,880 Speaker 1: the Mason's very much so. Um. And if you were 112 00:06:24,120 --> 00:06:27,120 Speaker 1: a mirror maker and it got out that you had 113 00:06:27,240 --> 00:06:32,200 Speaker 1: told someone how to make mirrors, you were frequently killed, right, yeah, 114 00:06:32,520 --> 00:06:36,600 Speaker 1: trade secret. But when mirrors were introduced, um, when good 115 00:06:36,640 --> 00:06:40,480 Speaker 1: mirrors were introduced, not polished subsidian, things changed a little bit, 116 00:06:40,600 --> 00:06:43,440 Speaker 1: especially with art. Right Yeah, I never really considered that, 117 00:06:43,480 --> 00:06:46,520 Speaker 1: but that it spawned something that would become a hallmark 118 00:06:46,560 --> 00:06:49,240 Speaker 1: of the art world, which is the self portrait. Right 119 00:06:49,320 --> 00:06:51,800 Speaker 1: before that, you couldn't draw yourself because you could not 120 00:06:51,880 --> 00:06:55,359 Speaker 1: see yourself. That's exactly right, And you could, but I 121 00:06:55,360 --> 00:06:58,040 Speaker 1: mean you're gonna use like maybe a pond or well, 122 00:06:58,480 --> 00:07:00,760 Speaker 1: piece of polished medal or something like that. Imagine like 123 00:07:01,440 --> 00:07:03,240 Speaker 1: going out and looking at a pond and going back 124 00:07:03,240 --> 00:07:04,760 Speaker 1: and sitting down that I was opposed to having a 125 00:07:04,760 --> 00:07:08,679 Speaker 1: mirror there. Yes, really simplified it. It's also not coincidental 126 00:07:08,839 --> 00:07:12,840 Speaker 1: that UM good mirrors came about at the same time 127 00:07:12,840 --> 00:07:17,760 Speaker 1: that UM linear perspective was introduced into art. What. Yeah, 128 00:07:17,840 --> 00:07:23,920 Speaker 1: there's a guy named um Filippo Brunus Bruno LLESHI nice, Chuck, 129 00:07:24,000 --> 00:07:27,280 Speaker 1: thank you for doing that, UM, and he he I 130 00:07:27,280 --> 00:07:30,160 Speaker 1: guess discovered linear perspective because I think it's one of 131 00:07:30,240 --> 00:07:32,960 Speaker 1: the things that was always there. We just stumbled upon 132 00:07:33,000 --> 00:07:36,440 Speaker 1: it through mirrors. That's how we figured it out. Yeah, 133 00:07:36,440 --> 00:07:38,320 Speaker 1: because if you look at a mirror, all of a sudden, 134 00:07:38,600 --> 00:07:42,800 Speaker 1: linear perspective really comes into focus, right you will. Well. 135 00:07:42,840 --> 00:07:45,880 Speaker 1: And then scientists UM said hey, we could use these 136 00:07:45,920 --> 00:07:49,360 Speaker 1: to make like reflecting telescopes, and that was what year 137 00:07:49,440 --> 00:07:51,840 Speaker 1: was at. That was a long time ago. The first 138 00:07:51,840 --> 00:07:55,960 Speaker 1: reflecting telescope was invented by a guy named James Bradley 139 00:07:56,440 --> 00:07:59,440 Speaker 1: just off the top of my head. Very well done. Uh, 140 00:07:59,480 --> 00:08:03,000 Speaker 1: And the mirrors were also used by a very very 141 00:08:03,040 --> 00:08:07,560 Speaker 1: famous scientist early scientists named Archimedes. Supposedly, Yeah, I wrote 142 00:08:07,560 --> 00:08:10,720 Speaker 1: an article on archimedes death. Ray. Oh did you write that? Yeah? 143 00:08:10,760 --> 00:08:12,800 Speaker 1: Did you ever read it? I did back in a 144 00:08:12,840 --> 00:08:15,280 Speaker 1: while ago. Just out of interest, how about that? Thanks 145 00:08:15,280 --> 00:08:17,640 Speaker 1: a lot man. Sure did you see in it? Um? 146 00:08:17,800 --> 00:08:20,160 Speaker 1: Some I can't remember. It was one of the Ivy 147 00:08:20,240 --> 00:08:23,440 Speaker 1: League schools. They tried to set things on fire with 148 00:08:23,560 --> 00:08:26,840 Speaker 1: this system of mirrors. That archie, that's who it was, 149 00:08:27,000 --> 00:08:31,880 Speaker 1: and they succeeded. Yes, And the MythBusters claimed it was busted, 150 00:08:31,920 --> 00:08:34,439 Speaker 1: like they set a small fire. But I think they 151 00:08:34,440 --> 00:08:36,480 Speaker 1: busted it because they said it wasn't enough to like 152 00:08:37,400 --> 00:08:39,600 Speaker 1: sink a ship. But m I T I mean, they 153 00:08:39,800 --> 00:08:42,720 Speaker 1: caused quite a fire on that boat, and of course 154 00:08:42,760 --> 00:08:44,800 Speaker 1: they had. I mean I saw this set up online today. 155 00:08:44,800 --> 00:08:47,240 Speaker 1: It was pretty massive. I don't know if Archimedes had 156 00:08:47,320 --> 00:08:50,400 Speaker 1: that kind of technology or at least that many mirrors 157 00:08:50,400 --> 00:08:52,800 Speaker 1: at its disposal, or maybe he did, and plus they 158 00:08:52,840 --> 00:08:55,280 Speaker 1: had I think they used pretty good mirrors too. Yeah, 159 00:08:55,320 --> 00:08:56,800 Speaker 1: well it was legend though. They don't know if the 160 00:08:56,840 --> 00:08:59,800 Speaker 1: Archimedes sing is true. Right. We know that he invented 161 00:08:59,840 --> 00:09:02,640 Speaker 1: the water screw and let's save countless lives. What's that 162 00:09:03,320 --> 00:09:07,440 Speaker 1: It's a way to deliver water from the ground top side. 163 00:09:07,559 --> 00:09:10,400 Speaker 1: Oh really yeah cool? You have to check it out, 164 00:09:10,440 --> 00:09:15,079 Speaker 1: smart dude. Um so chuck, We now know the comprehensive 165 00:09:15,920 --> 00:09:19,680 Speaker 1: broad strokes of the history of mirrors. Right, Yes, let's 166 00:09:19,679 --> 00:09:22,199 Speaker 1: talk about mirror physics. We work for how Stuff Works 167 00:09:22,240 --> 00:09:25,680 Speaker 1: dot com, which means we're pretty much obligated to discuss 168 00:09:25,720 --> 00:09:28,600 Speaker 1: the physics of whatever we're talking about any time it applies, right, 169 00:09:28,600 --> 00:09:32,679 Speaker 1: And that's true, and mirrors are definitely one of those times. Yes, 170 00:09:33,040 --> 00:09:35,599 Speaker 1: So Chuck take it away. Well, I can cover the 171 00:09:35,640 --> 00:09:37,800 Speaker 1: first part because it makes sense to me. The law 172 00:09:37,840 --> 00:09:40,880 Speaker 1: of reflection um Josh says that when you bounce array 173 00:09:40,920 --> 00:09:43,280 Speaker 1: of light off the surface, it bounces back off in 174 00:09:43,320 --> 00:09:46,800 Speaker 1: a certain way, and it is um the angle of 175 00:09:46,840 --> 00:09:50,120 Speaker 1: incidences is when it comes in the angle of reflection. 176 00:09:50,120 --> 00:09:53,480 Speaker 1: It when it bounces off, and it matches so that 177 00:09:53,559 --> 00:09:55,560 Speaker 1: the way they pointed out in the article, which makes 178 00:09:55,600 --> 00:09:57,839 Speaker 1: sense to me, is like at sunset, the sun is 179 00:09:57,920 --> 00:09:59,960 Speaker 1: very low on the horizon, so it bounces off at 180 00:10:00,000 --> 00:10:03,079 Speaker 1: a low angle, or approaches the water at a low angle, 181 00:10:03,120 --> 00:10:05,360 Speaker 1: like at a lake. Let's say, then it bounces off 182 00:10:05,400 --> 00:10:07,120 Speaker 1: of that lake at the same low angle, like right 183 00:10:07,120 --> 00:10:09,520 Speaker 1: into your face. Right, But if it seems brighter, if 184 00:10:09,559 --> 00:10:13,840 Speaker 1: the sun's overhead though, the sunlight is coming down under 185 00:10:13,880 --> 00:10:16,800 Speaker 1: the lake and it's reflecting back up basically over your head. 186 00:10:17,760 --> 00:10:23,199 Speaker 1: You're looking at a horizontal angle pretty much, and this 187 00:10:23,280 --> 00:10:26,640 Speaker 1: is happening on a vertical angle. Yeah, that's why you'll 188 00:10:26,640 --> 00:10:30,920 Speaker 1: get like more glare at a sunrise or a sunset scenario. Um. 189 00:10:31,000 --> 00:10:33,480 Speaker 1: And what you're saying, the angle of incidence equals the 190 00:10:33,520 --> 00:10:37,120 Speaker 1: angle of reflection. Right. Indeed, if you take if a 191 00:10:37,679 --> 00:10:40,400 Speaker 1: if a beam of light is shot at a ninety 192 00:10:40,400 --> 00:10:43,520 Speaker 1: degree angle or no, let's say eighty degree angle, it's 193 00:10:43,559 --> 00:10:45,960 Speaker 1: going to bounce off at an opposite eighty degree angle. 194 00:10:46,400 --> 00:10:48,800 Speaker 1: So both are at eighty degrees. But if you look 195 00:10:48,800 --> 00:10:51,719 Speaker 1: at the whole thing, the incidents and the reflection, it's 196 00:10:51,760 --> 00:10:54,920 Speaker 1: going to cover a hundred and sixty degrees right right, 197 00:11:19,240 --> 00:11:21,079 Speaker 1: all right, So that's the first part. That's that's how 198 00:11:21,640 --> 00:11:24,640 Speaker 1: that explains how light reacts with with reflection, and that's 199 00:11:24,640 --> 00:11:27,720 Speaker 1: where the smooth surface with with most things like say, 200 00:11:28,040 --> 00:11:32,560 Speaker 1: look at my hand man, Take a look at these hands, um, 201 00:11:32,640 --> 00:11:35,559 Speaker 1: the the light that's bouncing off of them. What's giving 202 00:11:35,640 --> 00:11:39,800 Speaker 1: us the ability to see these huge, awesome hands, um, 203 00:11:41,160 --> 00:11:45,920 Speaker 1: is they're not huge. Are they are smaller than average size? No, 204 00:11:46,040 --> 00:11:48,360 Speaker 1: they're they're bigger than mine. I got small hands. I 205 00:11:48,400 --> 00:11:51,000 Speaker 1: wouldn't see you have small hands. Let's see now those 206 00:11:51,000 --> 00:11:53,760 Speaker 1: are like, those are totally normal. I don't have hair 207 00:11:53,800 --> 00:11:55,360 Speaker 1: on the back of my hands either. I've got hair 208 00:11:55,360 --> 00:12:00,880 Speaker 1: in my first knuckles. Yeah, Robin Williams. Um, what's allowing 209 00:12:00,960 --> 00:12:03,400 Speaker 1: us to see our hands right now and judge their 210 00:12:03,520 --> 00:12:07,920 Speaker 1: size and scale is, um, what's called diffuse reflection. Which 211 00:12:08,280 --> 00:12:10,800 Speaker 1: the light that's coming off of all of these light 212 00:12:10,800 --> 00:12:13,880 Speaker 1: bulbs right now are hitting all these different areas, these 213 00:12:13,880 --> 00:12:17,000 Speaker 1: different services on my hands, and it's bouncing off, it's 214 00:12:17,040 --> 00:12:22,120 Speaker 1: being scattered right the mirror with the highly reflective surface. Um, 215 00:12:22,240 --> 00:12:26,240 Speaker 1: what we have is called specular reflection. And that is 216 00:12:26,280 --> 00:12:30,199 Speaker 1: where it's pretty close to the law of reflection, where 217 00:12:30,440 --> 00:12:33,560 Speaker 1: the angles coming in at one or the lights coming 218 00:12:33,559 --> 00:12:36,840 Speaker 1: in at one angle and coming off the at the 219 00:12:36,880 --> 00:12:40,959 Speaker 1: same degree in the opposite direction. Right, Um, Which is 220 00:12:41,280 --> 00:12:44,160 Speaker 1: why we're allowed to see ourselves in a piece of 221 00:12:44,360 --> 00:12:48,040 Speaker 1: glass with metal on the back. And what this creates 222 00:12:48,080 --> 00:12:50,800 Speaker 1: when you're looking at yourself is called the virtual image. Right. 223 00:12:51,120 --> 00:12:53,480 Speaker 1: I find it fascinating. Yeah, me too, And it's a 224 00:12:53,480 --> 00:12:56,600 Speaker 1: little brain melty for me, of course. But at the 225 00:12:56,600 --> 00:12:59,600 Speaker 1: same time you realize, like, well, you've grown up around 226 00:12:59,600 --> 00:13:03,240 Speaker 1: mirrors the whole time, and no one has any real 227 00:13:03,320 --> 00:13:07,160 Speaker 1: concept of of how they work. Right, We just take 228 00:13:07,200 --> 00:13:10,000 Speaker 1: for granted that they do work, but you don't really 229 00:13:10,080 --> 00:13:13,320 Speaker 1: give much thought to how they're working. Right, Like the 230 00:13:13,400 --> 00:13:16,720 Speaker 1: Venus effect. Did you read about that? Yeah, that that's 231 00:13:16,920 --> 00:13:19,720 Speaker 1: explained that because this is where when we talk about 232 00:13:20,080 --> 00:13:22,920 Speaker 1: Actually the Venus effect is two different things, and both 233 00:13:22,960 --> 00:13:24,920 Speaker 1: of them kind of melt my brain. That the left 234 00:13:24,960 --> 00:13:28,160 Speaker 1: and right being reversed, which is not actually true, and 235 00:13:28,160 --> 00:13:30,640 Speaker 1: then the venus effects. So let's talk about both of those. Okay, Well, 236 00:13:30,679 --> 00:13:33,680 Speaker 1: the Venus effect is basically just shows how little we 237 00:13:33,800 --> 00:13:37,280 Speaker 1: can grasp or how little we grasp mirrors and how 238 00:13:37,280 --> 00:13:40,320 Speaker 1: they work. If you look at paintings of the Venus 239 00:13:40,480 --> 00:13:44,960 Speaker 1: de Milo, Venus the goddess um almost always she's holding 240 00:13:45,000 --> 00:13:47,560 Speaker 1: a hand mirror, and in the painting you can see 241 00:13:47,600 --> 00:13:50,520 Speaker 1: her face in the mirror, but she's looking at herself 242 00:13:50,520 --> 00:13:53,079 Speaker 1: in the mirror, and her face is painted in the 243 00:13:53,120 --> 00:13:55,199 Speaker 1: mirror for the benefit of the viewer. But you take 244 00:13:55,280 --> 00:13:58,760 Speaker 1: for granted that she's viewing herself, when in actuality, if 245 00:13:58,840 --> 00:14:01,040 Speaker 1: you could see Venus is in the mirror, she wouldn't 246 00:14:01,040 --> 00:14:02,760 Speaker 1: be able to see herself she'd see you in the 247 00:14:02,800 --> 00:14:07,080 Speaker 1: mirror because of the angle or the law of reflection. Yeah, 248 00:14:07,120 --> 00:14:09,760 Speaker 1: and that's the only way I finally understood that was 249 00:14:09,800 --> 00:14:12,520 Speaker 1: when I remembered, like in my film set Days, when 250 00:14:12,559 --> 00:14:16,160 Speaker 1: you shoot a person looking in a mirror, they aren't 251 00:14:16,360 --> 00:14:18,800 Speaker 1: They don't see themselves in the mirror, clearly, because you 252 00:14:18,800 --> 00:14:21,080 Speaker 1: would see the camera behind them so that the mirror 253 00:14:21,120 --> 00:14:23,680 Speaker 1: is angled, and it looks like they're looking at themselves 254 00:14:23,680 --> 00:14:25,960 Speaker 1: and primping, but they're not seeing themselves. Pretty cool, right, 255 00:14:26,800 --> 00:14:29,560 Speaker 1: So that makes sense to me now it does, isn't it. Yeah? Okay, 256 00:14:29,880 --> 00:14:32,840 Speaker 1: the other thing you were saying is left and right, Yeah, 257 00:14:32,880 --> 00:14:35,120 Speaker 1: it's not actually left and right. Yeah, this one was 258 00:14:35,160 --> 00:14:36,920 Speaker 1: a little brain melty, but I think I finally got 259 00:14:36,920 --> 00:14:40,800 Speaker 1: it too. Okay, So consider that what you're not, what 260 00:14:40,840 --> 00:14:44,280 Speaker 1: you're seeing isn't actually your reflection, but another version of 261 00:14:44,320 --> 00:14:47,560 Speaker 1: yourself in the mirror world. Right. If you look at 262 00:14:47,600 --> 00:14:49,920 Speaker 1: it that way, then the mirror represents the halfway point. 263 00:14:49,960 --> 00:14:54,240 Speaker 1: It's always halfway between you and your virtual self, right, right, 264 00:14:54,320 --> 00:14:57,200 Speaker 1: Because your virtual self, that image of yourself in the 265 00:14:57,240 --> 00:15:01,240 Speaker 1: mirror is always twice as it's always two times away 266 00:15:01,240 --> 00:15:04,320 Speaker 1: from you. With the mirror representing the halfway point right, 267 00:15:04,440 --> 00:15:07,200 Speaker 1: So your two feet from the mirror, and your virtual 268 00:15:07,240 --> 00:15:09,520 Speaker 1: self is another two feet away from you. Right, You 269 00:15:09,520 --> 00:15:11,680 Speaker 1: see what I'm saying. Yeah, And the left and right 270 00:15:11,720 --> 00:15:13,800 Speaker 1: thing isn't really left and right, it's really front and 271 00:15:13,800 --> 00:15:17,400 Speaker 1: back that are reversed. You again, think of yourself as 272 00:15:17,400 --> 00:15:21,080 Speaker 1: the virtual image you walk into the mirror world, you 273 00:15:21,200 --> 00:15:23,440 Speaker 1: take you go another two feet away from where you're 274 00:15:23,480 --> 00:15:26,000 Speaker 1: just standing, so you're now for your four feet away 275 00:15:26,000 --> 00:15:28,720 Speaker 1: from where you're just standing and turn around right, Which 276 00:15:28,760 --> 00:15:32,120 Speaker 1: is weird because it actually gives the virtual image something 277 00:15:32,160 --> 00:15:35,360 Speaker 1: of its own identity, doesn't it does. It's a little creepy. Yeah, 278 00:15:35,480 --> 00:15:37,120 Speaker 1: So when you're looking at a mirror, you're it's not 279 00:15:37,160 --> 00:15:41,120 Speaker 1: a reflection of you from the mirrors perspective. It's like that. 280 00:15:41,240 --> 00:15:43,320 Speaker 1: The one example they gave was if you wrote something 281 00:15:43,320 --> 00:15:45,560 Speaker 1: on a piece of paper and then held that paper 282 00:15:45,640 --> 00:15:47,160 Speaker 1: up to the light and looked at it from the back, 283 00:15:47,240 --> 00:15:50,040 Speaker 1: it would appear backwards. But it's not right. You're just 284 00:15:50,080 --> 00:15:54,600 Speaker 1: behind it, yes, man, isn't it. Yeah? It's pretty interesting stuff. 285 00:15:54,680 --> 00:15:56,760 Speaker 1: And I gotta say when you two things, when you 286 00:15:56,880 --> 00:16:01,880 Speaker 1: mentioned doing mirrors, I said to myself, really, And then 287 00:16:01,920 --> 00:16:03,680 Speaker 1: when we told Jerry what we were doing this on. 288 00:16:03,720 --> 00:16:06,560 Speaker 1: She was like, really, yeah, but it's I think it's 289 00:16:06,640 --> 00:16:08,840 Speaker 1: much more interesting than I originally thought. Well again, it's 290 00:16:08,880 --> 00:16:11,800 Speaker 1: like the butterfly swings, you know, like we just have 291 00:16:11,840 --> 00:16:14,360 Speaker 1: to know that if we're gonna understand absolutely everything that's 292 00:16:14,400 --> 00:16:17,600 Speaker 1: going on in the world, which is our mission. Yes. Uh, 293 00:16:17,720 --> 00:16:20,960 Speaker 1: should we talk about curved mirrors now? Yeah, because we 294 00:16:20,960 --> 00:16:23,440 Speaker 1: were talking about virtual images, there's actually a way to 295 00:16:23,480 --> 00:16:27,080 Speaker 1: project a real image where this thing isn't in the mirror. 296 00:16:27,080 --> 00:16:29,720 Speaker 1: It's outside of the mirror, but it's not really there. 297 00:16:29,720 --> 00:16:33,760 Speaker 1: It's a projected image and that uses, um, concave mirrors. 298 00:16:33,880 --> 00:16:38,040 Speaker 1: You might be familiar with holograms, right, is that the 299 00:16:38,120 --> 00:16:42,000 Speaker 1: same concept there? He uses concave mirrors. And actually, if 300 00:16:42,000 --> 00:16:44,160 Speaker 1: you want to see a really cool example of a 301 00:16:44,200 --> 00:16:49,360 Speaker 1: hologram produced by a set of concave and flat mirrors, um, 302 00:16:49,440 --> 00:16:53,400 Speaker 1: you should type in mirrage in YouTube and look for 303 00:16:53,440 --> 00:16:55,720 Speaker 1: the one that's a lowercase just mirrage And it's a 304 00:16:55,760 --> 00:16:59,120 Speaker 1: little piggy um And it's pretty cool the demonstration that 305 00:16:59,160 --> 00:17:01,760 Speaker 1: this guy does. Yeah, I'll check that out. But Chuck, 306 00:17:02,040 --> 00:17:05,240 Speaker 1: there's concave and convex, right, yeah, convex is the one 307 00:17:05,280 --> 00:17:08,919 Speaker 1: that curves outward and it reflects at a wider angle 308 00:17:09,400 --> 00:17:12,399 Speaker 1: near the edges in the center, So things are actually 309 00:17:12,440 --> 00:17:14,760 Speaker 1: smaller and you can cover more areas. So that's why 310 00:17:14,840 --> 00:17:17,199 Speaker 1: they'll use those. Uh, they'll stick them on like your 311 00:17:17,200 --> 00:17:20,960 Speaker 1: passenger mirrors, so you can see more area around your car. 312 00:17:21,119 --> 00:17:23,480 Speaker 1: And it also notes you know, objects are smaller than 313 00:17:23,520 --> 00:17:26,520 Speaker 1: they appear or closer than they appear. Objects are smaller 314 00:17:26,560 --> 00:17:29,200 Speaker 1: than the appear. But they are smaller than they than 315 00:17:29,240 --> 00:17:31,680 Speaker 1: they appear. But that's not really that doesn't matter. It's 316 00:17:31,680 --> 00:17:34,240 Speaker 1: whether they're like in your back seat or not. Yeah, 317 00:17:34,280 --> 00:17:36,800 Speaker 1: and they actually um, there are have been rumors over 318 00:17:36,840 --> 00:17:40,160 Speaker 1: the years at department stores put convex mirrors, slightly convex 319 00:17:40,240 --> 00:17:42,760 Speaker 1: mirrors in their changing rooms to make you like a 320 00:17:42,880 --> 00:17:44,879 Speaker 1: pear tallerant thinner in the clothing that you try on. 321 00:17:45,000 --> 00:17:48,240 Speaker 1: Remember that Seinfeld where Eline like buys that dress, figured 322 00:17:48,440 --> 00:17:50,640 Speaker 1: that they had a skinny mirror, And I think Barneys 323 00:17:50,640 --> 00:17:53,359 Speaker 1: are blooming deals. Yeah, forgot about that. Yeah, I don't know. 324 00:17:53,400 --> 00:17:56,520 Speaker 1: I think that's probably urban legend, but who knows, um chuck. 325 00:17:56,600 --> 00:18:00,240 Speaker 1: The other one, like we said, was concave convert jing. 326 00:18:00,600 --> 00:18:03,359 Speaker 1: We use those for holograms. They also use that to 327 00:18:03,480 --> 00:18:06,080 Speaker 1: light the Olympic torch. Yeah, I didn't realize that either. 328 00:18:06,160 --> 00:18:08,600 Speaker 1: I think that's a nod to Archimedes too. Probably, so 329 00:18:09,440 --> 00:18:15,440 Speaker 1: you're probably a little more um acquainted with convex mirrors. 330 00:18:15,840 --> 00:18:19,480 Speaker 1: No concave mirrors for like shaving or No, those horrible 331 00:18:19,560 --> 00:18:23,320 Speaker 1: mirrors that show your like hair and detail. Those are awful, 332 00:18:23,400 --> 00:18:27,240 Speaker 1: they really are. Don't ever look in those nonreversing mirror, 333 00:18:27,240 --> 00:18:31,000 Speaker 1: which really is pretty simple. It's just two mirrors perpendicular 334 00:18:31,040 --> 00:18:34,160 Speaker 1: to each other, right, Yeah, And the deal is with 335 00:18:34,240 --> 00:18:38,240 Speaker 1: that they meet at the angle and so you technically 336 00:18:38,280 --> 00:18:40,439 Speaker 1: can see a non reverse image, but you've got that 337 00:18:40,560 --> 00:18:43,160 Speaker 1: line running down the center of you. They don't make 338 00:18:43,200 --> 00:18:47,000 Speaker 1: like a flat, single nonreversing mirror. No they don't. I 339 00:18:47,040 --> 00:18:49,160 Speaker 1: think it's physically impossible. It's not like they don't make 340 00:18:49,160 --> 00:18:51,080 Speaker 1: it like they're not interested. It's just can't be done. 341 00:18:51,119 --> 00:18:54,040 Speaker 1: But what's funny is there's a guy named um John 342 00:18:54,680 --> 00:18:58,800 Speaker 1: Derby who has a patent. In seven when he was alive, 343 00:18:58,840 --> 00:19:02,600 Speaker 1: he had a patent for a nonreversing mirror. By sticking 344 00:19:02,600 --> 00:19:05,320 Speaker 1: two mirrors together, I could get a patent for that. 345 00:19:05,359 --> 00:19:08,760 Speaker 1: I could fill out the patent application for that you could. Yeah, 346 00:19:08,800 --> 00:19:11,800 Speaker 1: it's like take mirror A and stick it perpendicular to 347 00:19:11,800 --> 00:19:14,280 Speaker 1: mirror B. Right there, give me my patent. Well, but 348 00:19:14,320 --> 00:19:17,359 Speaker 1: then John Derby's family would come after you. Hopefully it 349 00:19:17,440 --> 00:19:21,040 Speaker 1: ran out by now. And just for simpleness, Josh, two 350 00:19:21,040 --> 00:19:25,280 Speaker 1: way mirrors as seen in every cop shakedown movie ever made. Yes, now, 351 00:19:25,400 --> 00:19:28,560 Speaker 1: this is fascinating, Chuck. How does the two way mirror work? Well, 352 00:19:28,600 --> 00:19:31,360 Speaker 1: it's really pretty easy. It's just it's the same concept 353 00:19:31,359 --> 00:19:34,240 Speaker 1: of the mirror, but it's a very thin. It's very 354 00:19:34,320 --> 00:19:38,359 Speaker 1: much a lighter reflection the material they use and the 355 00:19:38,400 --> 00:19:41,399 Speaker 1: coated side. When it faces the lit room, some of 356 00:19:41,400 --> 00:19:43,880 Speaker 1: the light reflects and some goes into the dark room 357 00:19:43,880 --> 00:19:47,679 Speaker 1: behind it. So basically like you know, you can't you 358 00:19:47,680 --> 00:19:50,240 Speaker 1: can see only see one way right because of the 359 00:19:50,320 --> 00:19:55,360 Speaker 1: light mainly. So it's just like very thin reflective surface 360 00:19:55,400 --> 00:19:58,000 Speaker 1: where if you're not if you turn in, if you 361 00:19:58,040 --> 00:20:00,440 Speaker 1: turn on lights in both rooms, you'd be we'll see 362 00:20:00,480 --> 00:20:03,399 Speaker 1: through that reflective surface, right, Yeah, it's all about the lighting. Yeah, 363 00:20:03,560 --> 00:20:06,240 Speaker 1: and that's a movie there. There's several movie mirror things 364 00:20:06,240 --> 00:20:08,600 Speaker 1: that are done in like every movie, and that's one 365 00:20:08,640 --> 00:20:11,400 Speaker 1: of them. With the cop movie and inevitably the person 366 00:20:11,440 --> 00:20:14,040 Speaker 1: getting questioned will always walk right up and like be 367 00:20:14,160 --> 00:20:15,960 Speaker 1: staring into the face of the person on the other 368 00:20:16,000 --> 00:20:18,960 Speaker 1: side that they can't see. And then the other favorite 369 00:20:19,000 --> 00:20:22,919 Speaker 1: of mine, which one of the SNL shorts aped, was 370 00:20:23,119 --> 00:20:26,080 Speaker 1: um the classic horror movie scene where you where you 371 00:20:26,080 --> 00:20:28,320 Speaker 1: look in the medicine cabinet and the mirror and then 372 00:20:28,359 --> 00:20:30,720 Speaker 1: you open the medicine cabinet and then you close it 373 00:20:30,760 --> 00:20:33,160 Speaker 1: and the dude is right behind you. That's a classic. 374 00:20:33,280 --> 00:20:36,320 Speaker 1: It is there's um again on YouTube. I think there's 375 00:20:36,320 --> 00:20:39,760 Speaker 1: a a montage, like a four minute montage of that 376 00:20:39,960 --> 00:20:43,639 Speaker 1: being used over and times. Dude and it still gets people. Yeah, 377 00:20:43,760 --> 00:20:45,640 Speaker 1: but now that the whole spin is to do that 378 00:20:45,680 --> 00:20:47,800 Speaker 1: and then there's not someone there, and then they'll turn 379 00:20:47,840 --> 00:20:50,600 Speaker 1: around and that's where they are something. Yeah, just jerking 380 00:20:50,600 --> 00:20:53,520 Speaker 1: the audience around. That's in there too. Uh oh it 381 00:20:53,680 --> 00:20:56,680 Speaker 1: is huh yeah. Yeah, it's not just people closing there 382 00:20:56,680 --> 00:20:59,720 Speaker 1: someone saying there's ones where they're not standing there. Yeah. 383 00:21:00,040 --> 00:21:03,200 Speaker 1: I love those movie conventions that are The other one too, 384 00:21:03,280 --> 00:21:05,560 Speaker 1: is it doesn't even do with mirrors, but the scene 385 00:21:05,560 --> 00:21:08,119 Speaker 1: where you're where someone is searching for the files and 386 00:21:08,320 --> 00:21:11,200 Speaker 1: then the person's office after dark, and you know they're 387 00:21:11,240 --> 00:21:13,679 Speaker 1: coming up the steps and they opened the door and 388 00:21:13,720 --> 00:21:15,680 Speaker 1: you're like they're pinched. And then they opened the door 389 00:21:15,680 --> 00:21:18,239 Speaker 1: and the person is gone, and there's like a window open, right, 390 00:21:18,320 --> 00:21:21,359 Speaker 1: and it's just like the curtains. Hundreds and hundreds of 391 00:21:21,400 --> 00:21:23,760 Speaker 1: time is still done yet I'm still like, oh my gosh, 392 00:21:23,840 --> 00:21:28,320 Speaker 1: here they come. What about Poultergeist, the great classic mirror 393 00:21:28,359 --> 00:21:31,040 Speaker 1: scene where the guys like picking at that little blister 394 00:21:31,200 --> 00:21:33,680 Speaker 1: and ends up pulling his whole face off. Yeah, that's 395 00:21:33,720 --> 00:21:37,679 Speaker 1: pretty creepy. Yeah, classic, Thank you Toby Hooper? Did he 396 00:21:37,720 --> 00:21:40,840 Speaker 1: make that? Yeah? I like got this right? He produced it, right, 397 00:21:40,920 --> 00:22:07,440 Speaker 1: that's right. I always think he directed that. What else, Chuck, Well, 398 00:22:07,480 --> 00:22:12,440 Speaker 1: there's some superstitions around mirrors in folklore, um summoning Bloody 399 00:22:12,440 --> 00:22:14,639 Speaker 1: Mary by saying her names three times in a mirror, 400 00:22:14,720 --> 00:22:19,080 Speaker 1: or candy Man, if you're a little more recent, that's 401 00:22:19,080 --> 00:22:22,520 Speaker 1: a good one. Breaking a mirror supposedly bad luck because 402 00:22:22,920 --> 00:22:26,080 Speaker 1: um for seven years, because they believe that the soul 403 00:22:26,119 --> 00:22:29,880 Speaker 1: regenerates every seven years. Yeah, that explains it, doesn't it. Yeah, 404 00:22:29,880 --> 00:22:31,879 Speaker 1: And that's why vampires have no soul. That's why they 405 00:22:31,880 --> 00:22:34,479 Speaker 1: can't see themselves in mirrors, and a couple of them 406 00:22:34,520 --> 00:22:37,960 Speaker 1: I haven't heard of are if you give birth and 407 00:22:38,000 --> 00:22:40,520 Speaker 1: look in a mirror too soon afterward, you will see 408 00:22:40,560 --> 00:22:44,120 Speaker 1: ghostly faces peek out from behind the reflection. I've never 409 00:22:44,119 --> 00:22:46,200 Speaker 1: heard that one in you know, I had heard of 410 00:22:46,240 --> 00:22:49,040 Speaker 1: sitting shiver though. Yeah, what's the deal with that one? Well, 411 00:22:49,160 --> 00:22:51,760 Speaker 1: if you're Jewish and somebody dies, part of the morning 412 00:22:51,800 --> 00:22:53,800 Speaker 1: process is to cover all the mirrors in the house. 413 00:22:55,160 --> 00:22:59,640 Speaker 1: Uh to say that in the Talmud? Shut up, chuck. Also, 414 00:23:00,080 --> 00:23:04,199 Speaker 1: we have gotten conflicting um information about whether or not 415 00:23:04,520 --> 00:23:10,840 Speaker 1: it is taboo among Judaism to be cremated, did you notice? Yeah? 416 00:23:10,920 --> 00:23:13,160 Speaker 1: And what we and I'll stand behind what we found, 417 00:23:13,240 --> 00:23:17,520 Speaker 1: which was that reform Jews will do it, but they 418 00:23:17,560 --> 00:23:20,040 Speaker 1: it's still not like encouraged. And then but it is 419 00:23:20,040 --> 00:23:25,680 Speaker 1: actually forbidden in the actual Jewish text. So there, fine, 420 00:23:25,880 --> 00:23:28,800 Speaker 1: is that it? I think that's about it? Um? Oh, 421 00:23:28,920 --> 00:23:31,119 Speaker 1: New Year's Eve, right, Yeah, I hadn't heard of this 422 00:23:31,119 --> 00:23:33,320 Speaker 1: one either. If you go up to a mirror on 423 00:23:33,400 --> 00:23:35,480 Speaker 1: New Year's Eve with a candle in your hand, and 424 00:23:35,560 --> 00:23:38,720 Speaker 1: you say the name of a dead person, probably a 425 00:23:38,800 --> 00:23:42,440 Speaker 1: dead loved one, um, in a loud voice, their face 426 00:23:42,440 --> 00:23:45,679 Speaker 1: should appear in the mirror. Never heard that. And this 427 00:23:45,760 --> 00:23:49,720 Speaker 1: is my favorite one, the ancient Chinese mythology. Um, you 428 00:23:49,760 --> 00:23:52,320 Speaker 1: know how you see weird movement in like the corner 429 00:23:52,359 --> 00:23:54,399 Speaker 1: of a mirror every once in a while. Have you 430 00:23:54,440 --> 00:23:57,199 Speaker 1: ever noticed that? Uh? Sure, I just figured it was 431 00:23:57,320 --> 00:23:59,240 Speaker 1: like your mind playing tricks on you. I'm sure it 432 00:23:59,320 --> 00:24:03,720 Speaker 1: is on the through Chinese pal Then what it is are, um, 433 00:24:03,880 --> 00:24:07,600 Speaker 1: the mirror people the mere Kingdom. There's a group of 434 00:24:07,640 --> 00:24:10,160 Speaker 1: opposites who live in the mirror Kingdom, and they are 435 00:24:10,200 --> 00:24:13,679 Speaker 1: sworn to do battle with us. Yeah, and if this 436 00:24:13,760 --> 00:24:17,000 Speaker 1: were North mythology, we'd lose, and we may lose in 437 00:24:17,000 --> 00:24:19,800 Speaker 1: this case too. But they are in a I guess 438 00:24:19,800 --> 00:24:24,200 Speaker 1: a magical slumber. Um. But when we catch a little weird, 439 00:24:24,359 --> 00:24:27,960 Speaker 1: unexplained movement in the corners of mirrors, Um, this is 440 00:24:28,040 --> 00:24:32,199 Speaker 1: these people stirring in their sleep, waiting to wake up 441 00:24:32,240 --> 00:24:35,320 Speaker 1: and kill us all in our sleep. I'll remember that 442 00:24:35,400 --> 00:24:37,400 Speaker 1: next time I see something in the corner of my eye. 443 00:24:37,720 --> 00:24:40,600 Speaker 1: So that's it for mirrors. Um, that's it, I mean, 444 00:24:40,640 --> 00:24:43,960 Speaker 1: that is it? Nothing else? There is literally nothing else 445 00:24:43,960 --> 00:24:47,080 Speaker 1: to say about mirrors. Nope. And uh, if you think 446 00:24:47,280 --> 00:24:50,159 Speaker 1: that there is we defy you to go to how 447 00:24:50,200 --> 00:24:53,200 Speaker 1: stuff works dot com and type mirrors into the search bar. 448 00:24:54,040 --> 00:25:01,200 Speaker 1: Pale listener, mail time listener, Maile John, this is a little, 449 00:25:01,320 --> 00:25:05,320 Speaker 1: uh cool organization that we want to support here And 450 00:25:06,200 --> 00:25:09,200 Speaker 1: how long you've been smoked free, buddy? It's over four 451 00:25:09,240 --> 00:25:13,879 Speaker 1: months now? Crazy so proud, Hi Chucking Josh. I travel 452 00:25:13,920 --> 00:25:15,879 Speaker 1: outside the city every weekend listen to your podcast, and 453 00:25:15,880 --> 00:25:19,000 Speaker 1: I always share my new knowledge with friends. Needless to say, 454 00:25:19,040 --> 00:25:21,520 Speaker 1: I'm the Friday Night's smarty pants and I rather like it. 455 00:25:21,800 --> 00:25:24,480 Speaker 1: Why I'm writing, I want to promote the New York 456 00:25:24,480 --> 00:25:27,080 Speaker 1: City Walk to Beat Lung Cancer. I'm one of the 457 00:25:27,119 --> 00:25:29,920 Speaker 1: head chair persons. At twenty years old. I never thought 458 00:25:29,920 --> 00:25:33,119 Speaker 1: I would share anything, but I love my new responsibility 459 00:25:33,440 --> 00:25:36,240 Speaker 1: as I am making a huge difference to an underdog 460 00:25:36,280 --> 00:25:40,359 Speaker 1: cause how could cancer be an underdog? Josh? Is the question? 461 00:25:40,359 --> 00:25:42,760 Speaker 1: I don't know. I think it's pretty bad. When you 462 00:25:42,800 --> 00:25:44,640 Speaker 1: hear someone has lung cancer, the first thing that comes 463 00:25:44,680 --> 00:25:46,720 Speaker 1: to your mind is, probably did hear she smoked? It 464 00:25:46,760 --> 00:25:49,960 Speaker 1: never fails. It is a valid question. Uh. Funding for 465 00:25:50,040 --> 00:25:52,920 Speaker 1: lung cancers completely dwarfed by other cancers that are nearly 466 00:25:52,960 --> 00:25:55,639 Speaker 1: as fatal and is completely due to the stigma of 467 00:25:55,680 --> 00:25:58,919 Speaker 1: a smoker's disease. I get turned away by sponsors and 468 00:25:59,000 --> 00:26:01,399 Speaker 1: media all the time him because no one wants to 469 00:26:01,440 --> 00:26:04,639 Speaker 1: support a disease that is so preventable. But the thing is, 470 00:26:04,760 --> 00:26:09,520 Speaker 1: it isn't people who get LC second hand for no 471 00:26:09,560 --> 00:26:12,400 Speaker 1: reason at all happens all the time. Why don't people 472 00:26:12,440 --> 00:26:16,000 Speaker 1: ask those with skin cancer if they wore sunscreen, or 473 00:26:16,000 --> 00:26:18,440 Speaker 1: people who have heart attacks if they ate. Well, it's 474 00:26:18,480 --> 00:26:20,440 Speaker 1: just silly. But looking at the numbers, it just doesn't 475 00:26:20,440 --> 00:26:23,560 Speaker 1: add up. Um.
