Chemistry is necessarily an experimental science: its conclusions are drawn from data and its principles supported by evidence from facts. ~ Michael Faraday - 1791 to 1867
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

Pierre Curie voluntarily exposed his arm to the action of radium for several hours. This resulted in damage resembling a burn that developed progressively and required several months to heal. Henri Becquerel had by accident a similar burn as a result of carrying in his vest pocket a glass tube containing radium salt. He came to tell us of this evil effect of radium exclaiming in a manner at once delighted and annoyed: “I love it but I owe it a grudge.” - Marie Curie 1867 to 1934 Chemist Physicist
When you hear a physicist invoke the uncertainty principle keep a hand on your wallet. ~ David Griffiths b. 1942
I see some parallels between the shifts of fashion in mathematics and in music. In music the popular new styles of jazz and rock became fashionable a little earlier than the new mathematical styles of chaos and complexity theory. Jazz and rock were long despised by classical musicians but have emerged as art-forms more accessible than classical music to a wide section of the public. Jazz and rock are no longer to be despised as passing fads. Neither are chaos and complexity theory. But still classical music and classical mathematics are not dead. Mozart lives and so does Euler. When the wheel of fashion turns once more quantum mechanics and hard analysis will once again be in style. ~ Freeman Dyson b. 1923 - Mathematician and Physicist
It is strange that only extraordinary men make the discoveries which later appear so easy and simple. - Georg C. Lichtenberg 1742 to 1799 Physicist
We think there is color we think there is sweet we think there is bitter but in reality there are atoms and a void. ~ Democritus c. 460 – c. 370 BC
Archimedes’ finding that the crown was of gold was a discovery; but he invented the method of determining the density of solids. Indeed discoverers must generally be inventors; though inventors are not necessarily discoverers. - William Ramsay 1852 to 1916 Chemist
All of physics is either impossible or trivial. It is impossible until you understand it and then it becomes trivial. ~ Ernest Rutherford 1871 to 1937
