To me, there has never been a higher source of earthly honor or distinction than that connected with advances in science.

It can scarcely be denied that the supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience.

If we knew what it was we were doing, it would not be called research, would it?

As far as the laws of mathematics refer to reality, they are not certain; and as far as they are certain, they do not refer to reality.

The process of scientific discovery is, in effect, a continual flight from wonder.

Science is the century-old endeavour to bring together... perceptible phenomena... through systematic thought.
