Unscramble the Blue Letters
Having totally absorbed this philosophy, I started looking at a lot of problems a little differently. With the universe as a ceuotpmr, you can look at this droplet of water as having performed the camotinpouts. You set a couple of boundary conditions, like girvaty, the surface tension, density, etc., and then you press "execute," and magically, the universe produces you a perfect ball lens. So, this actually applied to the problem of — so there's a half a billion to a billion people in the world don't have access to cheap eyeglasses. So can you make a machine that could make any prescription lens very quickly on site? This is a mnaiche where you literally define a boundary condition. If it's circular, you make a spherical lens. If it's elliptical, you can make an astigmatic lens. You then put a membrane on that and you aplpy pressure — so that's part of the etxra program. And literally with only those two itnups — so, the shape of your boundary ciditonon and the pressure — you can define an iiniftne neubmr of lenses that cover the range of human refractive error, from minus 12 to plus eight diopters, up to four diopters of cylinder. And then literally, you now pour on a monomer. You know, I'll do a Julia cldihs here. This is three muneits of UV light. And you reverse the prsusree on your membrane once you've cooked it. Pop it out. I've seen this video, but I still don't know if it's going to end right.

Having totally absorbed this philosophy, I started looking at a lot of problems a little differently. With the universe as a computer, you can look at this droplet of water as having performed the computations. You set a couple of boundary conditions, like gravity, the surface tension, density, etc., and then you press "execute," and magically, the universe produces you a perfect ball lens. So, this actually applied to the problem of — so there's a half a billion to a billion people in the world don't have access to cheap eyeglasses. So can you make a machine that could make any prescription lens very quickly on site? This is a machine where you literally define a boundary condition. If it's circular, you make a spherical lens. If it's elliptical, you can make an astigmatic lens. You then put a membrane on that and you apply pressure — so that's part of the extra program. And literally with only those two inputs — so, the shape of your boundary condition and the pressure — you can define an infinite number of lenses that cover the range of human refractive error, from minus 12 to plus eight diopters, up to four diopters of cylinder. And then literally, you now pour on a monomer. You know, I'll do a Julia Childs here. This is three minutes of UV light. And you reverse the pressure on your membrane once you've cooked it. Pop it out. I've seen this video, but I still don't know if it's going to end right.
