The central moral issue of science is that we do not have a science of peace and hardly know where to begin in building one.

Try hard to find out what you're good at and what your passions are, and where the two converge, and build your life around that.

I certainly saw science as a kind of calling, and one with as much legitimacy as a religious calling.

So many of the things I've predicted were technologies that were just sitting right in front of us.

My ambitions were already very clearly fixed by the time I was 6 or 7.

Being successful at a very young age gave me the confidence and the capability to try out other things.

Although I am a public figure, I'm still a little shy. I don't think my own personality is important. I prefer to keep some small dosage of privacy.
