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

Imagination is more important than knowledge.

I think that a particle must have a separate reality independent of the measurements. That is an electron has spin, location and so forth even when it is not being measured. I like to think that the moon is there even if I am not looking at it.

One thing I have learned in a long life: that all our science, measured against reality, is primitive and childlike -- and yet it is the most precious thing we have.

A society's competitive advantage will come not from how well its schools teach the multiplication and periodic tables, but from how well they stimulate imagination and creativity.

A theory is something nobody believes, except the person who made it. An experiment is something everybody believes, except the person who made it.
