From the time of Dante [Alighieri], when you have the Ptolemaic universe, you had God on the outside like a hypersphere, and then in the center you have the Earth, all the seven heavens and layers, and then you have the Mount of Purgatory and Hell right in the center, and here's Satan flapping his wings and he keeps making the lake of Cocytus ice so you can't get out. So, again, where Heaven and Hell are, who the hell knows that now?

I think [H.P. Lovecraft] recognized what he was dealing with, he was dealing with demons. And he was dealing with creatures that're suffering. There's no way out of this suffering.

I met a guy who had the same theory and wrote a book about it. His name is Walter C. Wright Jr. His book is called Gravity Is a Push. I wrote to him and told him about my father, and he said he wished he'd met him. My father died quite a while ago.

Around the corner [ of the Carnegie Delicatessen] is the Russian Tea Room, which is now out of business. Which is awful. I remember going in there and seeing the ballerinas trotting in there like they were prize horses, with their hair, their sunglasses. Really amazing. They were all White Russians. This is where [Leon] Theremin met a lot of people, and where the KGB eventually picked him up.

I said, "Well, why do you believe in the Klein Bottle?" He said, "Because I can imagine it." I said, "You don't have to imagine a Mobius strip. It's right there in front of you!" But [Buckminster Fuller] couldn't see how that could involve a cross cap, meaning something that couldn't be reduced to a two-dimensional surface. Which it does. It's because he was thinking that the matrix was the thing that a fly could walk over the edge of, like a torus.

My father would conclude his dissertations by saying, "Of course, [Albert] Einstein never believed in gravity. It was a distortion of space." And so my father couldn't believe that an attraction at a distance was a reality.
