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 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 Chemist

Although Nature needs thousands or millions of years to create a new species man needs only a few dozen years to destroy one. ~ Victor Scheffer 1906 to 2011 - Biologist
