traits than the rest of us except for being smart and creative, and those being character

traits. Then, on the other hand, I wrote a biography of Richard Feynman and a biography

of Isaac Newton. Now, there are two great scientific geniuses whose characters were

in some superficial ways completely different. Isaac Newton was solitary, antisocial, I think

unpleasant, bitter, fought with his friends as much as with his enemies. Richard Feynman

was gregarious, funny, a great dancer, loved women. Isaac Newton, I believe, never had

sex. Richard Feynman, I believe, had plenty. So you can't generalize there.

On the other hand, they were both, as I tried to get in their heads, understand their minds,

the nature of their genius, I sort of felt I was seeing things that they had in common,

and they were things that had to do with aloneness. Newton was much more obviously alone than

Feynman, but Feynman didn't particularly work well with others. He was known as a great

teacher, but he wasn't a great teacher, I don't think, one on one. I think he was a

great lecturer. I think he was a great communicator. But when it came time to make the great discoveries

of science, he was alone in his head. Now, when I say he, I mean both Feynman and Newton,

and this applies, also, I think, to the geniuses that I write about in The Information, Charles

Babbage, Alan Turing, Ada Byron. They all had the ability to concentrate with a sort

of intensity that is hard for mortals like me to grasp, a kind of passion for abstraction

that doesn't lend itself to easy communication, I don't think.
