I’m positive that in 100 years much of what I take to be true today will be proved to be wrong， maybe even embarrassingly wrong， and I try really hard to identify what it is that I am wrong about today.

Mathematics is not a spectator sport. You have to get involved.

Invention is not enough. Tesla invented the electric power we use, but he struggled to get it out to people. You have to combine both things: invention and innovation focus, plus the company that can commercialize things and get them to people.

Women, they have minds, and they have souls, as well as just hearts. And they've got ambition, and they've got talent, as well as just beauty. I'm so sick of people saying that love is just all a woman is fit for.
