The natural scientist is concerned with a particular kind of phenomena ... he has to confine himself to that which is reproducible ... I do not claim that the reproducible by itself is more important than the unique. But I do claim that the unique exceeds the treatment by scientific method. Indeed it is the aim of this method to find and test natural laws.

Aristotle was by far a less able thinker than Plato ... he was completely overwhelmed by Plato.

Everything comes to him who knows how to wait.

I confess, that very different from you, I do find sometimes scientific inspiration in mysticism ... but this is counterbalanced by an immediate sense for mathematics.

You know, what Einstein has just said isn't so stupid.

God made the bulk; the surface was invented by the devil.

It isn't right. It isn't even wrong.
