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

The whole of science is nothing more than a refinement of everyday thinking.

I'm one of those people that think Thomas Edison and the light bulb changed the world more than Karl Marx ever did.

It is mere rubbish thinking, at present, of origin of life; one might as well think of origin of matter.

To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science.

The man of science is a poor philosopher.
