Imagination is more valuable than information.

I do not play games. There is not time for it. When I get through with work, I don't want anything that requires the working of the mind.

I do not like to state an opinion on a matter unless I know the precise facts.

One must console oneself with the thought that time has a sieve through which most of these important things run into the ocean of oblivion and what remains after this selection is often still trite and bad.

I urge a willingness to reserve a place in rational science for non-rational wonder.

Be a loner. That gives you time to wonder, to search for the truth. Have holy curiosity. Make your life worth living.

The belief in an external world independent of the perceiving subject is the basis of all natural science. Since, however, sense perception only gives information of this external world or of "physical reality" indirectly, we can only grasp the latter by speculative means. It follows from this that our notions of physical reality can never be final. We must always be ready to change these notions - that is to say, the axiomatic basis of physics - in order to do justice to perceived facts in the most perfect way.
