The chief philosophical value of physics is that it gives the mind something distinct to lay hold of which if you don’t Nature at once tells you you are wrong. ~ James Clerk Maxwell 1831 to 1879
The uniform character of mathematics is the essence of science for mathematics is the foundation of all exact scientific knowledge. ~ David Hilbert 1862 – 1943 Mathematician

I think it would be quite wrong to suggest that my colleagues have rejected me or that I reject them. Quite the reverse. It’s only a small vociferous group – mainly biologists I’m sorry to say – that go beyond ordinary scientific criticism and start becoming personal. ~ James Lovelock 1919 – present - Gaia Theorist Inventor Scientific Polymath
Still I had a lurking question. Would it not be better if one could really ‘see’ whether molecules as complicated as the sterols or strychnine were just as experiment suggested? ~ Dorothy Hodgkin - 1910 to 1984

Did the genome of our cave-dwelling predecessors contain a set or sets of genes which enable modern man to compose music of infinite complexity and write novels with profound meaning? …It looks as though the early Homo was already provided with the intellectual potential which was in great excess of what was needed to cope with the environment of his time.” - Susumu Ohno 1928 to 2000 Geneticist
Physics is actually too hard for physicists. ~ David Hilbert 1862 to 1943 (Mathematician)
Physics is littered with the corpses of dead unified field theories. ~ Freeman Dyson b. 1923
It does not help that some politicians and journalists assume the public is interested only in those aspects of science that promise immediate practical applications to technology or medicine. - Steven Weinberg 1933 to present Theoretical Physicist
