A mathematician is a device for turning coffee into theorems.
— Paul Erdos
To insure the adoration of a theorem for any length of time, faith is not enough, a police force is needed as well.
— Albert Camus theorem quote
I took a break from acting for four years to get a degree in mathematics at UCLA, and during that time I had the rare opportunity to actually do research as an undergraduate. And myself and two other people coauthored a new theorem: Percolation and Gibbs States Multiplicity for Ferromagnetic AshkinTeller Models on Two Dimensions, or Z2.
— Danica McKellar
No matter how correct a mathematical theorem may appear to be, one ought never to be satisfied that there was not something imperfect about it until it also gives the impression of being beautiful.
— George Boole
The pursuit of pretty formulas and neat theorems can no doubt quickly degenerate into a silly vice, but so can the quest for austere generalities which are so very general indeed that they are incapable of application to any particular.
— theorem quotation by E. T. Bell

I have found a very great number of exceedingly beautiful theorems.

I realized that anything to do with Fermat's Last Theorem generates too much interest.

Economists often like startling theorems, results which seem to run counter to conventional wisdom.

One cannot really argue with a mathematical theorem.

A mathematician is a person who can find analogies between theorems;
a better mathematician is one who can see analogies between proofs and the best mathematician can notice analogies between theories.
