In its efforts to learn as much as possible about nature modern physics has found that certain things can never be “known” with certainty. Much of our knowledge must always remain uncertain. The most we can know is in terms of probabilities. ~ Richard Feynman 1918 to 1988
Falsity in intellectual action is intellectual immorality. - Thomas Chrowder Chamberlin 1843 to 1928 Geologist

Geometry inasmuch as it is concerned with real space is no longer considered a part of pure mathematics; like mechanics and physics it belongs among the applications of mathematics. ~ Hermann Weyl 1885 to 1955 - Mathematician and Theoretical Physicist
The invention of logarithms came to the world as a bolt from the blue. No previous work had led up to it… It stands isolated breaking in upon human thought abruptly without borrowing from the work of other intellects or following known lines of mathematical thought. ~ John Moulton 1844 – 1921 - Mathematician
We were a polite society and I expected to lead a quiet life teaching mechanics and listening to my senior colleagues gently but obliquely poking fun at one another. This dream of somnolent peace vanished very quickly when (Ernest) Rutherford came to Cambridge. Rutherford was the only person I have met who immediately impressed me as a great man. He was a big man and made a big noise and he seemed to enjoy every minute of his life. I remember that when transatlantic broadcasting first came in Rutherford told us at a dinner in Hall how he had spoken into a microphone to America and had been heard all over the continent. One of the bolder of our Fellows said: “Surely you did not need to use apparatus for that.” ~ Geoffrey Fellows 1871 to 1937
Chemistry begins in the stars. The stars are the source of the chemical elements which are the building blocks of matter and the core of our subject. ~ Peter Atkins - 1940 to present
Our thoughts visions and fantasies have a physical reality. A thought is made of hundreds of electrochemical impulses. ~ Carl Sagan 1934 to 1996 Astrobiologist Planetary Scientist
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
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
