Instead of being the biological center of the Universe I believe our planet is just an assembly station but one with a major advantage over most other places. The constant presence of liquid water almost everywhere on the Earth is a huge advantage for life especially for assembling life into complex forms by the process we call ‘evolution.’ ~ Fred Hoyle 1915 to 2001 - Astrophysicist
In practical applications we are concerned only with comparatively small numbers; only stellar astronomy and atomic physics deal with ‘large’ numbers and they have very little more practical importance as yet than the most abstract pure mathematics. ~ G. H. Hardy 1877 – 1947 - Mathematician

What exactly is mathematics? Many have tried but nobody has really succeeded in defining mathematics; it is always something else. Roughly speaking people know that it deals with numbers figures with relations operations and that its formal procedures involving axioms proofs lemmas theorems have not changed since the time of Archimedes. ~ Stan Ulam 1909 – 1984 - Mathematician
I am busy just now again on electro-magnetism and I think I may have got hold of a good thing. ~ Michael Faraday 1791 – 1867
When you hear a physicist invoke the uncertainty principle keep a hand on your wallet. ~ David Griffiths b. 1942
If physics and biology one day meet and one of the two is swallowed up that one will be biology. ~ J. B. S. Haldane 1892 to 1964 - Biologist
An experiment is a question which science poses to Nature and a measurement is the recording of Nature’s answer. - Max Planck 1858 to 1947 Theoretical Physicist
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
The physical chemists never use their eyes and are most lamentably lacking in chemical culture. It is essential to cast out from our midst root and branch this physical element and return to our laboratories. ~ Henry Edward Armstrong 1848 to 1937
