Science is like sex: sometimes something useful comes out, but that is not the reason we are doing it — Richard P. Feynman Copy Share Image
A philosopher once said, 'It is necessary for the very existence of science that the same conditions always produce the same results.'… — Richard P. Feynman Copy Share Image
The fundamental principle of science, the definition almost, is this: the sole test of the validity of any idea is experiment. — Richard P. Feynman Copy Share Image
