"It is disconcerting to reflect on the number of students we have flunked in chemistry for not knowing what we later found to be untrue."
--quoted in Robert L. Weber, Science With a Smile (1992)

"Chemists are, on the whole, like physicists, only 'less so'.They don't make quite the same wonderful mistakes, and much what they do is an art, related to cooking, instead of a true science. They have their moments, and their sources of legitimate pride. They don't split atoms, as the physicists do. They join them together, and a very praiseworthy activity that is."
-- Anthony Standen, Science is a sacred cow (1958).

"All theoretical chemistry is really physics; and all theoretical chemists know it."
-- Richard P. Feynman

"An expert is a man who has made all the mistakes, which can be made, in a very narrow field."
-- Niels Henrik David Bohr (1885-1962)

"Science is the belief in the ignorance of the experts."
-- Richard Feynman, American physicist
