Games are the most elevated form of investigation.

All the fifty years of conscious brooding have brought me no closer to answer the question, "What are light quanta?" Of course today every rascal thinks he knows the answer, but he is deluding himself.

I want to go when I want. It is tasteless to prolong life artificially. I have done my share, it is time to go. I will do it elegantly.

The most precious things in life are not those you get for money.

If you are out to describe the truth, leave elegance to the tailor.

The most practical solution is a good theory.

All that's different about me is that I still ask the questions most people stopped asking at age five.
