I can't see the audience and I hate that. How many great grandparents are there in the audience? I can't see anything. Okay, you probably wonder why I am sitting, the answer is, because I'm a great grandfather, not a good grandfather, a great grandfather. And everybody knows great grandparents get to do any damn thing they please, including following my own grandfather's advice, which was whenever you give a talk to thousands of people about Richard Feynman, sustain yourself. (laughter, applauds) This is an extremely slackXX operation, and I'm a slackXX man, so I don't use these things. I decided when I said yes to do this thing that I really want to talk about is my friend Richard Feynman. I was one of the fortunate few that really get to know him, enjoy his presence. And I'm going to tell you Richard Feynman I knew. I'm sure there are other people here who can tell you Richard Feynman they knew, and it would probably be a different Richard Feynman. Richard Feynman is a very complex man. He was a man of many, many parts: he was of course, foremost, a very great scientist; he was an actor, you saw him act -- I also had the good fortune to be in those lectures-- back in the balcony, they were fantastic; he was a philosopher, he was a drum player, he was a teacher pAr excellence. Richard Feynman was also a showman, a normal showman, who was brash, irreverant, he was full of macho, a kind of macho one optism shape. He loved intellectual battle. He had a big ego. But the man had somehow a lot of room in the bottom, what I mean by that, is a lot of room in my case, can't speak for anybody else, but in my case a lot of room for another big ego. While not as big as his, but, fairly big. I always felt good to be with Feynman. It was always fun to be with him. He always made me feel smart. How can somebody like that make you feel smart? Somehow we did. He made me feel smart, he made me feel he is smart. He made me feel we were both smart, and two of us could solve any problem whatever. And in fact, sometimes we did do physics together. We never published papers together. But we did have a lot of fun. He love to win
