I, a universe of atoms, an atom in the universe.

The unanswerable mysteries... the attitude that all is uncertain... to summarize it - the humility of the intellect.

I don't feel frightened by not knowing things, by being lost in the mysterious universe without any purpose - which is the way it really is, as far as I can tell. Possibly. It doesn't frighten me.

There is nothing that living things do that cannot be understood from the point of view that they are made of atoms acting according to the laws of physics.

It is the facts that matter, not the proofs. Physics can progress without the proofs, but we can't go on without the facts ... if the facts are right, then the proofs are a matter of playing around with the algebra correctly.

If you're doing an experiment, you should report everything that you think might make it invalid - not only what you think is right about it; other causes that could possibly explain your results; and things you thought of that you've eliminated by some other experiment, and how they worked -to make sure the other fellow can tell they have been eliminated.

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