In science it is not enough to think of an important problem on which to work. It is also necessary to know the means which could be used to investigate the problem.

If you want to succeed in the world, you don't have to be much cleverer than other people. You just have to be one day earlier.

Three stages of truth for scientists: It's not true. If it is true, it's not very important. We knew it all along.

We turned the switch, saw the flashes, watched for ten minutes, then switched everything off and went home. That night I knew the world was headed for sorrow.
