WEBVTT - Geodesic Domes: The Wave of the Future That Wasn't 0:00:01.120 --> 0:00:04.560 Welcome to stuff you should know from how Stuff Works 0:00:04.600 --> 0:00:14.120 dot com. Hey, and welcome to the podcast. I'm British Josh. 0:00:14.240 --> 0:00:19.800 There's American Chuck, and there's neutral Swizzerland Jerry, which, by 0:00:19.840 --> 0:00:23.640 the way, now we're saying Swizzerland Switzerland. I just decided 0:00:23.880 --> 0:00:25.599 because it's close to the end of the year and 0:00:25.640 --> 0:00:27.920 I'm about to die of exhaustion. I love it. Uh. 0:00:28.480 --> 0:00:31.680 On the Friendly Fire Movie podcast, Ben Harrison, you know Ben, 0:00:31.880 --> 0:00:35.640 he says, uh, Nazis, Yeah, the Nazis. That's like kind 0:00:35.680 --> 0:00:38.760 of like a throwback. It's like the greatest generation way 0:00:38.800 --> 0:00:40.840 of saying yeah. And I know he does it as 0:00:40.880 --> 0:00:43.920 an affectation, but now I got it from him, and 0:00:43.920 --> 0:00:48.960 he got it from god knows where his great grandpa Nazi. Yeah, 0:00:49.360 --> 0:00:51.159 that's a pretty great way to because there's a lot 0:00:51.200 --> 0:00:56.120 of occasion to say the word Nazi a lot. Hell, 0:00:56.240 --> 0:00:58.000 you mentioned this, uh, And why did you say you 0:00:58.000 --> 0:01:05.760 were British? Because I say geodesic and you say geodesic 0:01:06.280 --> 0:01:08.600 and we just looked it up, which I mean, that's 0:01:08.640 --> 0:01:12.080 like the first time in years the lady said geodesic 0:01:12.240 --> 0:01:15.800 and I was like, yes, or in America geodesic and 0:01:15.800 --> 0:01:17.840 I said, we're both right, but then she didn't say 0:01:17.840 --> 0:01:21.000 though it was British, it could be like whatever South African. 0:01:21.840 --> 0:01:26.760 I guess, well africannor is not English. Well, yeah, you 0:01:26.760 --> 0:01:30.920 know what I mean. We're so far off course already. 0:01:31.200 --> 0:01:33.759 Jerry's just got Roman coming through her nose. She thought 0:01:33.760 --> 0:01:37.959 that was so funny. Um, thanks for the last, Jerry. Well, 0:01:38.000 --> 0:01:41.120 we are talking about geodesic desik. Maybe we should just 0:01:41.160 --> 0:01:44.839 say that every time, saying both. I'm sure people would 0:01:44.840 --> 0:01:47.320 love that. I'm gonna say geodesic because that's what I've 0:01:47.319 --> 0:01:50.960 always said. Okay, great, I'm gonna say geodesic. That's fine. Um, 0:01:51.080 --> 0:01:56.240 we're talking about domes, geodesic domes and um. If you 0:01:56.360 --> 0:02:00.960 have ever seen a weird contraption of a circular house, 0:02:01.320 --> 0:02:04.600 a ball house, you might call it a sphere house. 0:02:05.680 --> 0:02:08.240 You've seen a geodesic, don't. If you've ever been to 0:02:08.280 --> 0:02:11.960 Epcot um i went when he was a kid, you've 0:02:11.960 --> 0:02:15.520 seen a geodesic don't. They're all over the place. Do 0:02:15.560 --> 0:02:18.480 you all right? Do you like these as like people's 0:02:18.520 --> 0:02:22.480 houses in a neighborhood or wherever? No? I don't either, 0:02:23.080 --> 0:02:25.600 But I don't. I mean, I'm not gonna yuck. Anybody's yeah, 0:02:25.720 --> 0:02:28.080 you know what I'm so. I mean, when reading and researching, 0:02:28.200 --> 0:02:30.919 like they're cool and there are a lot of great advantages, 0:02:31.720 --> 0:02:34.760 then that will go over. But I just don't care 0:02:34.800 --> 0:02:38.800 for them. Aesthetically. I don't either. And actually, if you 0:02:38.919 --> 0:02:42.160 if you um read a quote from Buckminster Fuller, the 0:02:42.160 --> 0:02:44.840 guy who actually didn't invent you deseic domes, we'll get 0:02:44.840 --> 0:02:46.840 in all that. Anyway. He said, one of the reasons 0:02:46.880 --> 0:02:50.840 they never took off is because they're weird looking. They 0:02:50.919 --> 0:02:53.760 just are and and well, I'm not gonna say that. 0:02:54.560 --> 0:02:58.000 I really tell me later, Okay, Yeah, I just don't 0:02:58.000 --> 0:03:00.359 care for him. You know. It's like I'm a crap usman, 0:03:02.000 --> 0:03:06.960 California craftsman, bungalow type guy, which is about the opposite 0:03:06.960 --> 0:03:10.600 of a geodesic that it's pretty angular for sure, And 0:03:10.639 --> 0:03:14.919 the geodesic dome is angular. Everybody put your laptops away, 0:03:15.000 --> 0:03:19.320 geometry nerds, but it's not rectangular, and a craftsman is 0:03:19.320 --> 0:03:22.080 definitely rectangular. Like you can even make a case the 0:03:22.160 --> 0:03:25.160 roof is not a triangle. It's a rectangle on its side. 0:03:25.800 --> 0:03:29.560 Mm hmm. I just made that case. How's it going? Yeah, 0:03:29.639 --> 0:03:33.079 pretty good? I also, and although I probably will never 0:03:33.360 --> 0:03:37.720 live in one, I do love a modern, uh like 0:03:37.760 --> 0:03:41.040 a mid century modern. I love it, but I just 0:03:41.320 --> 0:03:44.240 it's not really like ultimately where I would want to 0:03:44.280 --> 0:03:47.160 live for the rest of my life. Well, okay, so 0:03:47.440 --> 0:03:49.960 I don't want to feel like I'm like in Finland 0:03:49.960 --> 0:03:53.200 in the winter or something like that. That's not I'm 0:03:53.240 --> 0:03:57.040 talking mid century American actually built for a family, and 0:03:57.160 --> 0:03:59.840 like the mid fifties early sixties. I love it. The 0:04:00.000 --> 0:04:02.360 has all little cool details and built ins in the 0:04:02.520 --> 0:04:04.880 wall that doesn't even really need to be there. You 0:04:04.880 --> 0:04:07.000 can see right through it because it's like wood spindles, 0:04:07.000 --> 0:04:11.040 and that's what I like, not ultra motern, mid century 0:04:11.080 --> 0:04:13.640 moter yeah, okay, mid center, Yeah, that's what we call it. 0:04:13.720 --> 0:04:15.120 But you still you don't think you could live in 0:04:15.160 --> 0:04:18.840 one of those, because I traft we had to get 0:04:18.839 --> 0:04:21.960 all new stuff. Like if we started over, like if 0:04:22.000 --> 0:04:23.640 our if our god for a bit of our house 0:04:23.680 --> 0:04:27.440 burned down and we lost everything, I could start over 0:04:27.520 --> 0:04:29.880 like that, But like the stuff that we have doesn't fit, 0:04:30.520 --> 0:04:34.040 Like you know understood, Grandma's antique bar doesn't really go 0:04:34.640 --> 0:04:36.800 in that setting. I've seen that bar and that thing 0:04:36.880 --> 0:04:40.000 is classic. Thank you you could put it anywhere. Grandma 0:04:40.040 --> 0:04:41.840 was a bit of a booze hound. Huh. Well, they 0:04:41.839 --> 0:04:44.480 didn't use as a bar. They had like humble figurines 0:04:44.520 --> 0:04:46.880 and stuff. And I saw it. It was funny. When 0:04:46.880 --> 0:04:49.080 I first saw it, I was like, oh God, I 0:04:49.080 --> 0:04:51.000 don't really want that, and like they're giving it to us, 0:04:51.360 --> 0:04:52.480 And then we turned it to a bar and it 0:04:52.560 --> 0:04:55.760 was like, it's amazing, what dirty liquor bottles you can 0:04:55.760 --> 0:05:00.120 really dress up a humble figuring cabinet. So clearly we're 0:05:00.160 --> 0:05:03.359 talking again about geodesic domes. And there was a period 0:05:03.400 --> 0:05:05.800 in time check where you could go into some neighborhoods 0:05:05.839 --> 0:05:09.000 around the country and you could find well to do 0:05:09.240 --> 0:05:16.160 hippie types, environmental types back to Earth's Um living in 0:05:16.200 --> 0:05:18.640 these geodesic domes. And it's not like they were living 0:05:18.640 --> 0:05:21.359 in a tent. It was their house had plumbing and 0:05:21.440 --> 0:05:24.160 heating and electricity and all this stuff. It's just that 0:05:24.240 --> 0:05:26.480 it was a dome. Yeah. There was one near where 0:05:26.480 --> 0:05:28.400 I grew up actually, and we would pass it going 0:05:28.440 --> 0:05:31.680 to elementary school and it was always just sort of like, yeah, 0:05:31.760 --> 0:05:35.479 there's those weirdos that built the weird house. Isn't it interesting? Though? 0:05:35.520 --> 0:05:39.080 Like that had some impact on who you are today. 0:05:39.160 --> 0:05:41.919 But how minute to how small, but seeing that every 0:05:41.920 --> 0:05:44.760 every day or every week day, that had to have 0:05:44.880 --> 0:05:47.200 some impact on you. Yeah, and there's was also one 0:05:47.200 --> 0:05:50.680 of those. Uh it was also partially underground even so 0:05:50.839 --> 0:05:53.680 there was an ex but then that was sort of 0:05:53.720 --> 0:05:56.200 built into a hill and so they were full on. 0:05:56.400 --> 0:05:58.120 They had a lot of hippie credit. Yeah, they were 0:05:58.160 --> 0:05:59.800 going to it and looking back, they were probably super 0:05:59.800 --> 0:06:03.440 cool people. Probably they were wearing berkin stocks way before 0:06:03.480 --> 0:06:07.359 anybody else is wearing berkin stocks. So let's talk a 0:06:07.360 --> 0:06:11.719 little bit about the first geodesic dome, a little geodesic history. Okay, 0:06:11.760 --> 0:06:14.680 all right, you you have to go way back, way 0:06:14.760 --> 0:06:19.440 way back to and not only do we have to 0:06:19.440 --> 0:06:22.520 go back, we have to go to Germany. Jenda, Germany. 0:06:23.640 --> 0:06:25.599 I don't know where that is. I don't either, but 0:06:25.680 --> 0:06:30.480 there is a very famous optics company called zeissure Um 0:06:30.520 --> 0:06:34.440 and Seiss wanted to build a planetarium on top of 0:06:34.440 --> 0:06:37.479 one of their factories or factory at Jenna, Germany, and 0:06:37.520 --> 0:06:41.680 they said, uh, please build this a planetarium. Walter Bowers 0:06:41.720 --> 0:06:44.120 Field where if if you didn't know if he was 0:06:44.160 --> 0:06:47.960 German or not, just listen to his name felt even 0:06:48.000 --> 0:06:51.279 more German. And he said, sure, let me think about 0:06:51.360 --> 0:06:53.520 this and I'll see what I can come up with. 0:06:53.760 --> 0:06:56.599 And he came up with what was widely pointed to 0:06:56.720 --> 0:06:59.320 as the world's first geodesic dome. Yeah, and it was 0:06:59.360 --> 0:07:01.760 a good It was a good idea for this project, 0:07:01.760 --> 0:07:04.840 in particular because they needed it to be light, because 0:07:04.839 --> 0:07:07.240 it had to go on top of a roof. Um, 0:07:07.279 --> 0:07:10.360 they needed to hold a lot of people. And obviously 0:07:10.400 --> 0:07:15.160 because it was a planetarium that that interior roundness was 0:07:15.240 --> 0:07:19.480 kind of key. Be weird to have a square planetarium, 0:07:19.600 --> 0:07:22.040 it would, you know, especially if you're like I didn't 0:07:22.040 --> 0:07:24.320 know Venus could take a corner like that. I didn't 0:07:24.320 --> 0:07:27.280 know he could do that. Uh, so that's what he did, 0:07:27.320 --> 0:07:30.880 and um, it was it really worked well. It did 0:07:31.080 --> 0:07:33.040 house a lot of people. I mean not house, but 0:07:33.320 --> 0:07:36.080 you know it could hold a lot of people. Uh, 0:07:36.120 --> 0:07:38.560 it can withstand storms and this is these are some 0:07:38.600 --> 0:07:43.200 of the factors that make them h not only popular, 0:07:44.000 --> 0:07:48.080 but like a good idea depending on where you are. 0:07:48.640 --> 0:07:51.440 It was like, if you're in Antarctica, they have them 0:07:51.440 --> 0:07:54.040 there and that it's perfect for that kind of weather. Yeah, 0:07:54.080 --> 0:07:55.920 there was a period in time of which we'll see 0:07:55.920 --> 0:07:58.920 in a second, where geodesic don't were like the house 0:07:58.960 --> 0:08:01.239 of the future. It was a very very good idea 0:08:01.280 --> 0:08:04.120 that never took off because everybody said, no, we think 0:08:04.120 --> 0:08:06.960 those are kind of weird, we don't feel comfortable with that, 0:08:07.040 --> 0:08:12.360 and pretty much so um uh. Bowersfeld's planetarium actually kicked 0:08:12.400 --> 0:08:16.000 off a planetarium craze. It was apparently the first planetarium 0:08:16.000 --> 0:08:18.320 on Earth, which I would make the case that you 0:08:18.360 --> 0:08:22.600 can just say the first planetarium in the universe that um. 0:08:22.760 --> 0:08:27.160 But because there were people who started to build planetariums 0:08:27.200 --> 0:08:29.960 as a result of this, gudesic domes kind of became 0:08:30.000 --> 0:08:32.640 a thing. But it wasn't until a guy named Richard 0:08:32.640 --> 0:08:37.040 Buckminster Fuller of Carbondale, Illinois, very big deal, came along 0:08:37.120 --> 0:08:41.080 and actually patented the geodesic dome that they really became 0:08:41.160 --> 0:08:43.840 that house of the future thing that I was talking about. Yeah, 0:08:43.880 --> 0:08:46.520 and he was an engineer and a sort of a 0:08:46.600 --> 0:08:51.080 visionary thinker, one of the great Americans. I think, Um, 0:08:51.200 --> 0:08:53.160 we could do a show on him altogether, I think. 0:08:53.880 --> 0:08:58.000 But his whole jam was like, well, first of all, 0:08:58.040 --> 0:09:01.080 he saw the inherent like good points to the um 0:09:01.120 --> 0:09:03.560 and we'll get into all those but first and foremost, 0:09:03.600 --> 0:09:05.960 you can you can have a huge volume of space 0:09:06.040 --> 0:09:09.720 with very little materials, very lightweight materials, and it's still 0:09:09.760 --> 0:09:14.160 be super strong, which is awesome. But so because of this, 0:09:15.160 --> 0:09:18.080 he thought like he had a higher goal in mind, 0:09:18.120 --> 0:09:20.480 which was like the housing in the future. Like they 0:09:20.480 --> 0:09:23.360 don't cost that much money, they can hold you know, 0:09:23.480 --> 0:09:26.800 people safely, and like this is how we should think 0:09:26.800 --> 0:09:29.360 about housing. Right. You could you could build it off 0:09:29.360 --> 0:09:31.960 side at a factory and deliver it by helicopter. Was 0:09:32.040 --> 0:09:33.960 that light kind of put it together about like a 0:09:34.040 --> 0:09:37.320 kid yep, And like you're saying it required because it 0:09:37.360 --> 0:09:42.960 could withstand more weight. Uh, it required less building materials, 0:09:42.960 --> 0:09:48.440 which meant it was lower cost um And supposedly you 0:09:48.440 --> 0:09:50.920 could put these things like a good kit together in 0:09:50.960 --> 0:09:53.400 a day if you were really cruising along at a 0:09:53.440 --> 0:09:58.240 good clip. Sure, so had some some high grade sixties 0:09:58.240 --> 0:10:05.640 speed give it all. Yeah, um man, you got me 0:10:05.640 --> 0:10:09.640 with that one. So so this just became plainly obvious 0:10:09.679 --> 0:10:11.520 that this is going to be the house of the future. 0:10:11.800 --> 0:10:14.240 There's um One of the other things about it is 0:10:14.480 --> 0:10:19.120 there is no other building structure that has a larger 0:10:19.320 --> 0:10:24.320 volume of space with the least amount of surface area. Yeah, 0:10:24.360 --> 0:10:27.679 and he got this idea through looking at nature. Uh. 0:10:27.720 --> 0:10:31.360 He very famously looked at things like crystals and seed 0:10:31.400 --> 0:10:34.720 pods and things like that and thought, like, you know nature, 0:10:35.040 --> 0:10:37.199 And a lot of people do this in design. They 0:10:37.200 --> 0:10:39.600 look to nature because nature has sort of proven to 0:10:39.600 --> 0:10:41.560 get it right usually over the years. Yeah. Like if 0:10:41.559 --> 0:10:43.680 you look at an eggshell, you're like, this thing shouldn't 0:10:44.559 --> 0:10:47.280 withstand anything, and yet it does. And it's a very 0:10:47.360 --> 0:10:50.160 curious thing. But it sure looks like it could slip 0:10:50.160 --> 0:10:53.000 out of a chicken's butt with ease, which is kind 0:10:53.040 --> 0:10:55.400 of what it does. Like, what if it was square, 0:10:55.559 --> 0:11:00.640 it slips out of the cloaca. That's true. So um, 0:11:00.679 --> 0:11:04.920 Bucky Fuller, as he's known, he apparently I don't know 0:11:04.960 --> 0:11:08.040 if he wasn't aware of Bowersfeld's design or something. Did 0:11:08.040 --> 0:11:09.840 you get that impression? I don't. I couldn't tell if 0:11:09.880 --> 0:11:12.120 this was nefarious. He seemed like a good guy, so 0:11:12.120 --> 0:11:14.920 I don't think he like stole this idea, but he 0:11:14.960 --> 0:11:17.440 was able to secure a patent. He did. And there's 0:11:17.480 --> 0:11:19.800 a really great Time article if you can find it's 0:11:19.840 --> 0:11:23.240 called di Maxian. American maxim was a word that was 0:11:23.679 --> 0:11:26.720 associated with him. Um, he he just made up words 0:11:26.760 --> 0:11:30.319 a lot, but he it tells it. It's from N. Four. 0:11:30.360 --> 0:11:32.440 It says that he was trying to figure out a 0:11:32.520 --> 0:11:35.520 geometry of energy, and he was using spheres as a 0:11:35.600 --> 0:11:40.199 model of energy. No idea, but he was putting spheres together. 0:11:40.480 --> 0:11:43.320 And his his idea was that when you put spheres together, 0:11:43.360 --> 0:11:46.240 they would just make a larger and larger sphere. But 0:11:46.600 --> 0:11:49.040 that's not what happened. If he took a central sphere 0:11:49.040 --> 0:11:51.560 and put other spheres around it and pushed it together, 0:11:52.040 --> 0:11:53.800 and what he found was that it started to make 0:11:54.559 --> 0:11:59.000 squares and triangles rather than a larger sphere. And he 0:11:59.080 --> 0:12:01.200 figured out that what he had just come up with 0:12:01.640 --> 0:12:03.760 was actually a very smart structure. That you could take 0:12:03.800 --> 0:12:06.640 those squares and divide those into triangles, and you could 0:12:06.679 --> 0:12:09.560 take the triangles and divide the triangles into even smaller triangles, 0:12:09.720 --> 0:12:12.320 and if you kind of curve the edges of the 0:12:12.360 --> 0:12:17.079 triangles inward towards some imaginary center inside the sphere and 0:12:17.200 --> 0:12:21.800 actually create a sphere. And technically it's a polyhedron, and 0:12:21.920 --> 0:12:26.240 most geodesic domes are a cosahedrons, which, if you play 0:12:26.600 --> 0:12:29.800 dungeons and Dragons, is just a twenty sided die. But 0:12:29.880 --> 0:12:33.760 the more you cut the sides into smaller and smaller triangles, 0:12:34.000 --> 0:12:37.800 the more the closer to an actual perfect sphere you 0:12:37.800 --> 0:12:41.560 you get. And that's a geodesic sphere. And if you 0:12:41.640 --> 0:12:43.520 cut it in half, or cut a portion of it 0:12:44.000 --> 0:12:47.560 and just use one half of it, that's a geodesic dome. Yeah, 0:12:47.559 --> 0:12:51.200 which is what you see like, Uh, it's not fully 0:12:51.320 --> 0:12:53.920 round because it has to be flat and sit on 0:12:54.000 --> 0:12:57.800 something right. Well, actually, um, the Spaceship Earth geodesic dome 0:12:58.520 --> 0:13:01.319 is a full sphere. But that is pretty rare. Uh. 0:13:01.360 --> 0:13:04.199 And I thought it was interesting too, um that they 0:13:04.240 --> 0:13:08.120 said that if you were just designing something on paper, 0:13:08.280 --> 0:13:10.760 you could just design bigger and bigger and it would 0:13:10.760 --> 0:13:15.240 just get stronger and stronger. But in reality, um, that's 0:13:15.280 --> 0:13:17.960 really not the case. Like when when rubber meets the road, 0:13:18.440 --> 0:13:20.800 they're really there's really only so big you can kind 0:13:20.840 --> 0:13:23.079 of get. Yeah, because I had no idea about this, 0:13:23.200 --> 0:13:25.760 you know, it's roughly familiar with geodesic domes. I didn't 0:13:25.760 --> 0:13:28.080 know any details. But one thing that I was surprised 0:13:28.080 --> 0:13:31.600 to find is that the triangles are not all the 0:13:31.640 --> 0:13:35.079 same size. They have to be adjusted to make this 0:13:35.200 --> 0:13:39.600 shape to make this circle or the sphere. So, um, 0:13:39.640 --> 0:13:42.400 if you're putting together one of these things, as we'll see, 0:13:42.760 --> 0:13:44.800 you have to be like, oh, this struck goes here, 0:13:45.120 --> 0:13:47.560 not here, and I actually put it here up on 0:13:47.600 --> 0:13:49.200 the top, and now I have to go take the 0:13:49.200 --> 0:13:52.320 whole thing apart again. And yeah, the less complex, the 0:13:52.360 --> 0:13:55.760 better impracticality. But yeah, you can really mess with it 0:13:55.800 --> 0:13:59.840 to make it virtually a perfect sphere out of triangles. Uh. Yeah, 0:14:00.000 --> 0:14:02.600 you mentioned a minute ago that and I think people 0:14:03.440 --> 0:14:06.440 that pay attention, we're probably like, oh, Josh is so 0:14:06.480 --> 0:14:10.880 funny or what did he just say? Did Buck Minister Fuller? Uh? 0:14:10.920 --> 0:14:14.520 Makeup words? He did, because he made up another word 0:14:14.880 --> 0:14:19.880 when it comes to these domes, Uh, tin segrity, which 0:14:19.960 --> 0:14:23.440 is not a good word, it's not He mixed two 0:14:23.440 --> 0:14:27.600 words together at tensional and integrity. Uh. And so that's 0:14:27.720 --> 0:14:31.760 the relationship between the tension and compression, and that really 0:14:31.800 --> 0:14:34.440 kind of describes how these things fit together and why 0:14:34.520 --> 0:14:37.600 they end up being super strong, even though when you 0:14:37.600 --> 0:14:39.480 look at it, you're like, man, I could blow that 0:14:39.520 --> 0:14:41.440 thing over, right. So let's let's say your break and 0:14:41.480 --> 0:14:44.040 then we'll get into like the actual dynamics going on. Okay, 0:14:44.200 --> 0:15:18.200 and geometry. Yes, yes, alright, Chuck, I promised it's time 0:15:18.240 --> 0:15:21.200 to talk to geometry. How did you do in geometry? 0:15:21.480 --> 0:15:24.720 I failed the first time aced to the second time. 0:15:24.840 --> 0:15:27.320 I'm actually really glad that I failed it because when 0:15:27.360 --> 0:15:29.480 I was forced to take it again by the man. 0:15:29.840 --> 0:15:33.600 And this is high school, right, yeah, um, I it clicked. 0:15:33.840 --> 0:15:37.080 And I've never understood any field of math like I 0:15:37.160 --> 0:15:40.000 understood geometry. I don't quite remember it now, but like 0:15:40.160 --> 0:15:43.880 I understood geometry like I was. Pythagoras is like brother, 0:15:44.160 --> 0:15:46.680 I kind of I wasn't quite at that level. But 0:15:46.760 --> 0:15:49.080 I feel like because I'm I have long sort of 0:15:49.120 --> 0:15:53.560 poo poo the maths. Yeah, but you've that right, well yeah, 0:15:53.560 --> 0:15:56.080 but I mean just for my my pea brain like 0:15:56.240 --> 0:15:59.840 understanding it. I understood geometry more than all the other maths. 0:16:00.560 --> 0:16:02.720 And uh I did okay in it for a for 0:16:02.760 --> 0:16:06.080 an English nerd. Yeah, you know, good enough, because it's 0:16:06.160 --> 0:16:09.000 completely different than anything else. I feel like in the 0:16:09.040 --> 0:16:12.280 geometry does seem like its own thing for very much, like, yeah, 0:16:12.320 --> 0:16:15.600 there's numbers and sigma makes an appearance and stuff like that, 0:16:15.640 --> 0:16:18.640 but it definitely seems to be It's different than algebra. 0:16:18.640 --> 0:16:20.840 I'll tell you that buddy shout out to Miss carn 0:16:21.240 --> 0:16:23.400 Read In high school. Oh, I wish I could remember 0:16:23.440 --> 0:16:26.000 my geometry teacher that when it clicked with she was great. 0:16:26.000 --> 0:16:28.640 She was one of those teachers that's like I was 0:16:28.720 --> 0:16:31.440 seventy years old. From the time that she was twenty 0:16:31.480 --> 0:16:34.720 eight till the time she was seventy, she was great, 0:16:34.760 --> 0:16:37.040 and then she turned back into twenty eight. Yeah. She 0:16:37.560 --> 0:16:39.720 remember she had this polka dot It's funny the things 0:16:39.720 --> 0:16:42.600 that you remember. She had this polka dot shirt where 0:16:42.640 --> 0:16:45.080 all the polka dots were collected at the bottom, and 0:16:45.120 --> 0:16:46.800 she said that it used to be all over, but 0:16:46.880 --> 0:16:49.760 she hung it up to dry. That was her big joke. 0:16:51.000 --> 0:16:53.400 She's like, welcome in my class. It's the only joke 0:16:53.480 --> 0:16:55.480 of the year. Let's get busy. Yeah, I bet you 0:16:55.520 --> 0:16:57.480 there's one person out there who had Miss carn and 0:16:57.560 --> 0:16:59.920 knows that shirt. Yeah. I hope it's a great joke, 0:17:00.080 --> 0:17:05.320 Miss carn Um. Okay, so we're talking geometry, right, Yeah. 0:17:05.600 --> 0:17:09.560 Do you remember our bridges episode. Remember we talked about 0:17:09.600 --> 0:17:12.879 bridge trusses, the bridges that are made up of triangular shapes, 0:17:13.280 --> 0:17:17.160 and we said, like those things are extraordinarily strong because 0:17:17.200 --> 0:17:21.560 their triangles. Same thing here can't beat them. A geodesic 0:17:21.640 --> 0:17:25.520 dome or sphere is a sphere made up of triangles, 0:17:25.600 --> 0:17:29.359 and if you actually take the triangular shape and build 0:17:29.400 --> 0:17:33.840 one in reality, it is one of the strongest shapes 0:17:33.920 --> 0:17:37.800 you can um create because wherever you press on it, 0:17:37.800 --> 0:17:41.240 it transfers that pressure that forced to the rest of 0:17:41.280 --> 0:17:45.480 the shape. So it distributes that kind of weight or 0:17:45.520 --> 0:17:48.719 pressure force or whatever you want to lay on on it. 0:17:48.720 --> 0:17:51.720 It distributes it evenly. And if you put another triangle 0:17:51.760 --> 0:17:54.240 together with one triangle, it sends it to the other 0:17:54.280 --> 0:17:57.040 triangle too, And so the more triangles you add, the 0:17:57.119 --> 0:18:02.240 more a force is distributed throughout. And that's basically it. 0:18:02.480 --> 0:18:04.480 That's why it's so strong. Like what you were saying, 0:18:04.520 --> 0:18:05.640 like you look at it and you're like, I could 0:18:05.680 --> 0:18:08.359 blow that over. You might be able to push it 0:18:08.400 --> 0:18:10.480 over and make it roll away if it's a sphere, 0:18:11.400 --> 0:18:15.000 but you you probably could not break it. Yeah, And 0:18:15.040 --> 0:18:17.440 when you look at like if you're inside one of these, 0:18:17.520 --> 0:18:20.280 it's usually covered with like wood or drywall or something, 0:18:20.600 --> 0:18:23.800 so it's not as evident, but on the outside you 0:18:23.960 --> 0:18:27.879 generally can still see this frame of triangles all fitting 0:18:27.920 --> 0:18:32.600 together beautifully to make something super super strong. Yes, and 0:18:32.680 --> 0:18:38.919 apparently the strongest version of a geodesic dome or sphere 0:18:39.720 --> 0:18:42.640 um is one that's actually made not just out of triangles, 0:18:42.680 --> 0:18:45.600 but out of pyramids. If you look at if you 0:18:45.640 --> 0:18:51.639 look at the Epcot Spaceship Earth Geodesic sphere, it's actually pyramids. 0:18:52.560 --> 0:18:56.280 All the triangles are actually Yeah, that is that's it. 0:18:56.440 --> 0:19:00.760 That's the money geodesic dome. Yeah, and that one, since 0:19:00.760 --> 0:19:03.560 we're on that is interesting and that uh one of 0:19:03.560 --> 0:19:06.399 the downfalls and we'll go over more later, but one 0:19:06.400 --> 0:19:09.920 of the downfalls of geodesic domes is sometimes rain doesn't 0:19:09.920 --> 0:19:13.960 treat them well. But the one at Epcot was just like, 0:19:14.720 --> 0:19:17.040 we're not even gonna pretend that we want to repel 0:19:17.080 --> 0:19:19.760 the rain. They have little grooves that actually collect the 0:19:19.840 --> 0:19:22.240 rain and that send it to one of those uh 0:19:22.440 --> 0:19:25.640 little corny lagoons. I love those, I know, I love 0:19:25.720 --> 0:19:28.439 everything about Epcot. I haven't been since I was in 0:19:28.480 --> 0:19:31.800 seventh grade. I mean, did they update it or is 0:19:31.800 --> 0:19:35.280 it still very much like the World of Tomorrow today? 0:19:35.359 --> 0:19:37.760 You know they've updated it. I mean the whole thing 0:19:37.960 --> 0:19:41.359 is still like that. Yeah, but there's like newer stuff, 0:19:41.400 --> 0:19:46.119 Like there's a really cool um ride an immersive ride 0:19:46.200 --> 0:19:50.720 called Soaring, where like you get lifted up and you're 0:19:50.720 --> 0:19:53.800 in front of this huge, giant curved movie screen and 0:19:53.840 --> 0:19:57.919 you're like, so soaring through this like the world, like 0:19:57.960 --> 0:20:00.159 a world tour. It's really neat, And did they move 0:20:00.240 --> 0:20:02.040 your little thing around so you feel like you're you 0:20:02.080 --> 0:20:05.080 definitely feel like you're soaring through there. Yeah, that's like 0:20:05.119 --> 0:20:07.440 the when they debuted that Back to the Future ride 0:20:07.520 --> 0:20:09.480 years ago. Was it like that. Yeah, you sit in 0:20:09.520 --> 0:20:12.920 the DeLorean and it's on hydraulics and it's like moving 0:20:12.920 --> 0:20:15.080 all around, but it's a movie screen in front of Yeah, 0:20:15.080 --> 0:20:17.160 and you're and you're going through. But it's it's amazing 0:20:17.200 --> 0:20:19.280 how like accurate they can sync that up to where 0:20:19.280 --> 0:20:21.359 you really feel like, like I remember that was at 0:20:21.359 --> 0:20:24.000 one point where the car was on the edge of 0:20:24.000 --> 0:20:26.600 a cliff and it was sort of teetering and it 0:20:26.640 --> 0:20:29.600 got really quiet, and then it teetered over and then 0:20:29.600 --> 0:20:32.159 it the car just stopped moving and he felt like 0:20:32.200 --> 0:20:35.320 you were falling just because it stopped moving. And if 0:20:35.320 --> 0:20:37.920 you like turned around and look backwards, you're like everyone's 0:20:37.920 --> 0:20:40.320 freaking out and you're just sitting in a car doing nothing, 0:20:41.160 --> 0:20:44.680 but everybody's going it was so great. I loved it. 0:20:44.920 --> 0:20:47.199 So we were saying, like this this thing pops up 0:20:47.240 --> 0:20:51.359 all over nature. Yeah, the geodesic dome did. This Time 0:20:51.400 --> 0:20:55.959 magazine put article put it really beautifully that, Um, it 0:20:56.040 --> 0:20:59.880 was like Buckminster Fuller had discovered a signature of God, 0:21:00.400 --> 0:21:06.120 who has made scared quotes because God ended the whole thing. 0:21:06.640 --> 0:21:09.359 Since it is such like a an efficient structure that 0:21:09.560 --> 0:21:11.159 can support a lot of weight, you do see it 0:21:11.160 --> 0:21:16.760 in things like eggs Cornia testicle, which I'm like, sure, really, 0:21:17.800 --> 0:21:20.520 I guess so I couldn't find that anywhere else, and 0:21:20.600 --> 0:21:25.879 I definitely typed testical geodesic dome into Google and it 0:21:25.920 --> 0:21:28.760 didn't really come back with anything. But this nineteen four 0:21:28.800 --> 0:21:31.520 Time article says it. So it's so well, the dome 0:21:31.680 --> 0:21:35.560 period is a pretty strong structure. Um. The Romans were 0:21:35.560 --> 0:21:40.200 building really big, strong domes a long long time ago, 0:21:40.280 --> 0:21:42.960 but they don't stay strong for long. That's sort of 0:21:42.960 --> 0:21:45.000 one of the problems with the dome just a regular dome, 0:21:45.760 --> 0:21:48.920 is that you need a lot of super heavy supporting 0:21:48.920 --> 0:21:51.760 materials and walls to keep it up, and over time 0:21:51.800 --> 0:21:55.400 they wear out. But uh, what Fuller did was took 0:21:55.440 --> 0:21:58.800 that sort of same principle and applied this geometry to 0:21:58.880 --> 0:22:02.639 it and triangles that the Romans you know, didn't think of, 0:22:03.359 --> 0:22:07.080 and the rest is history, I guess. Yeah. What what 0:22:07.119 --> 0:22:09.760 he found was that when you put these fears together, 0:22:09.840 --> 0:22:13.439 you you created what he called the vector equilibrium, the 0:22:13.560 --> 0:22:16.679 outward force of the thing that's trying to collapse it. 0:22:17.280 --> 0:22:19.879 You know, like if you if you could press down 0:22:19.920 --> 0:22:22.560 on the roof of the house, it would collapse outward 0:22:22.560 --> 0:22:25.000 to the sides. The same thing wants to happen to 0:22:25.080 --> 0:22:30.840 geodesic dome. But in a geodesic dome, that pressure outward 0:22:31.119 --> 0:22:34.840 from the force of gravity is actually equal to the 0:22:34.920 --> 0:22:42.119 force that's being distributed around it, the circumferential force, And 0:22:42.200 --> 0:22:46.800 since they're equal and equal measures, they cancel each other out. 0:22:47.640 --> 0:22:51.360
