The only people who did get some formulas were the Japanese. This was a very, very lovely beautiful dome. And all of the students, my associates who were involved in it, had a lot of pleasure with it.

Next picture. That was that dome at night.

Next picture. And that's one of those domes then delivered to one of the sites. You can see them all around the world in this kind of a mounting. This was at Whippany New Jersey, at the Bell Laboratories.

Next picture. This is one of the domes being this is my, one of my earliest domes being mounted on the roof of the Lincoln Laboratories, going up to be put on one of the Radomes.

Next picture. You saw this yesterday. This is at Thule in the northern end of Greenland.

Next picture. This is then getting into the plywood domes. And the plywood was very exciting, because I found it is possible to take absolutely flat sheets and they will you can make a sphere out of flat sheets. It doesn't sound logical, but you can. Again, remember this bending. You can take any two triangles and bend between them. I'd like you to take a postcard, if you take a postcard you can imagine this with me, take a postcard and it is a little longer than it is narrow, somebody give me a sheet of paper just a quadrangular sheet of paper? (Someone in the audience had a postcard) You've got a postcard? Oh, this is much better. Very good. Now I can bend it like that, can't I? Obviously I can do that, there is a bend. Now, I can also put a bend on that corner, making that into a triangle, and make a bend in this corner, making it into a triangle. Then I can bend this corner here, making it into a triangle. And then I can go from here to here and make this into a triangle. Now I've got one of the diamonds of a geodesic where there are two triangles side by side with a common ridgepole. In other words, I find that a quadrangle can receive five bends. Out of our six vectors, five can be bent in. And this, then, obviously can take any two triangles on my dome, and this overlaps into the next one, so if you know your mathematics carefully then you know what the whole pattern would be to be bolted onto the next units. So, that is the way, come back then to the plywood dome

There it is, and because as you get it out pretty flat, they look almost like flat pieces I very much emphasize this, you can understand that. So that these are you can see this is getting into a high frequency. These are all out in Des Moines, Iowa, these pictures can my body be removed? This was an extraordinary beautiful, beautiful plywood dome.

Next picture. Now those can get very high frequency and get relatively thin. And this is using the same principles, but developing a shingling orientation of the triangles. And this one is at Cornell where I then had, each one of these shingles, inside you can look out, but there is a little air so, we call this a pine cone dome and it is on the campus at Cornell. Remove my figure in front of there because I would really like you getting a feeling of it.

I found this a particularly nice kind of a dome. The aeronautical properties were great, the water shedding properties were excellent. Next picture. This is, then, getting into what is called the "Pease Dome", manufactured in Ohio.

Next picture. Where you get the standard pattern. Many of you are familiar with Pease Domes by now.

Next picture. This is the, a dome going into an Air Force into a plane. This is one going to Kabul, Afghanistan.

Next picture. This dome we were asked, Kabul, Afghanistan, 1954. If you will look at your world map then you will find Afghanistan to the east of Iran, Iraq, north of India and touching on Russia on its north side and China on this way. So China, Russia, it contains the Khyber pass. I spoke to you about there being main routes from the Orient to Europe. There was the Marco Polo one which went by the sea [lake] of Baikal and the Sea of Azof and the Black and so forth, coming in through the Bosporus into the Adriatic. But then just south of that, coming over the desert, Sinkiang and so forth was the one that came thru the Khyber pass and thru, then, Afghanistan.
