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
What exactly is mathematics? Many have tried but nobody has really succeeded in defining mathematics; it is always something else. Roughly speaking people know that it deals with numbers figures with relations operations and that its formal procedures involving axioms proofs lemmas theorems have not changed since the time of Archimedes. ~ Stan Ulam 1909 – 1984 - Mathematician

I think it would be quite wrong to suggest that my colleagues have rejected me or that I reject them. Quite the reverse.

The condition of matter I have dignified by the term Electronic THE ELECTRONIC STATE. What do you think of that? Am I not a bold man ignorant as I am to coin words? ~ Michael Faraday 1791 – 1867

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
