Chemistry unlike other sciences sprang originally from delusions and superstitions and was at its commencement exactly on a par with magic and astrology. ~ Thomas Thomson - 1773 to 1852
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

Physics is very muddled again at the moment; it is much too hard for me anyway and I wish I were a movie comedian or something like that and had never heard anything about physics! ~ Wolfgang Pauli 1900 – 1958
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
This most beautiful system of the sun planets and comets could only proceed from the counsel and dominion of an intelligent and powerful Being. And if the fixed stars are the centres of other like systems these being formed by the like wise counsel must be all subject to the dominion of One; especially since the light of the fixed stars is of the same nature with the light of the sun. ~ Isaac Newton 1642 to 1727
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

When you hear a physicist invoke the uncertainty principle keep a hand on your wallet. ~ David Griffiths b. 1942
There may be babblers wholly ignorant of mathematics who dare to condemn my hypothesis upon the authority of some part of the Bible twisted to suit their purpose. I value them not and scorn their unfounded judgment. ~ Nicolaus Copernicus 1473 – 1543 Mathematician and Astronomer
