Science is of value because it can produce something.

When I was a young man, Dirac was my hero. He made a breakthrough, a new method of doing physics. He had the courage to simply guess at the form of an equation, the equation we now call the Dirac equation, and to try to interpret it afterwards.

The inside of a computer is as dumb as hell but it goes like mad!

The only way to deep happiness is to do something you love to the best of your ability
