Stephen Hawking won [Babson Institute competition ] one year with his black hole stuff. It's keeping an open mind on whether gravity exists or not. I think my father believed this because ... when the wind blew on him, he'd get angry, because it was something he couldn't control.

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.

As a kid, I was getting information in areas that no one else was getting. I think that was one of the reasons my mother didn't want me to go to school too soon. Because I would be beaten to a pulp, you know, if I walked down the street and said there was no such thing as gravity.

When [my father] reached his majority, he was the head of the family. Everybody depended upon him. He went into a very uptight appearance; he would wear Chesterfield coats to work, Homburg hats, really getting into the whole thing. He knew people like Oscar Levant. He loved New York. He wanted to live there.

Buckminster Fuller was down in Pennsylvania, then he'd come up and go to his island in Maine. He wanted to remain a New Englander. He taught from '48 to '49 and '50 at Black Mountain College. That's where he met Kenneth Snelson. Fuller kind of stayed a Yankee right in the New England area. So it was pretty easy to get him to come on over, and we would have lectures at the Harvard Science Center.

Both [Nikola] Tesla and [Leon] Theremin were preternaturally young. I mean, for a long time Tesla was a young man well into his 70s. And so was Theremin, even though, at the end, he looked pretty old. But he was still doing things that young guys do, beyond the time you'd normally think people should be doing that stuff.

I actually challenged The Theosophical Society on their concept of planes of reality. I said, "What you're doing is, you're stacking two-dimensional surfaces in three-space. And you are not going into any other dimensions at all." And they were furious, because they thought I was attacking Madame [Elena] Blavatsky.
