God exists since mathematics is consistent, and the Devil exists since
we cannot prove it. -- Andre Weil
If I feel unhappy, I do mathematics to become happy. If I am happy, I do mathematics to keep happy.

Life is good for only two things, discovering mathematics and teaching
Young man, in mathematics you don't understand things, you just get used to
-- John von Neumann (1903-1957) [Hungarian/US mathematician and
Anyone who cannot cope with mathematics is not fully human. At best he
is a tolerable subhuman who has learned to wear shoes, bathe and not
make messes in the house. -- Lazarus Long, "Time Enough for Love", (Robert
A. Heinlein (1907-19??) [
science-fiction writer] ) US
Mathematicians are like lovers. Grant a mathematician the least
principle, and he will draw from it a consequence which you must also
grant him, and from this consequence another.
-- Bernard Le Bovier Fontelle
Math is like love -- a simple idea but it can get complicated.
"A mathematician is a blind man in a dark room looking for a black cat
which isn't there" - Charles R. Darwin (1809-1882) [English biologist]
Copernicus, Nicholaus (1473-1543)Mathematics is written for mathematicians
"A person who can, within a year, solve x^2 - 92y^2 = 1 is a mathematician."

"Obvious" is the most dangerous word in mathematics.
The traditional mathematics professor of the popular legend is
absentminded. He usually appears in public with a lost umbrella in each
hand. He prefers to face the blackboard and to turn his back to the
class. He writes a, he says b, he means c; but it should be d. Some of his
sayings are handed down from generation to generation.
"In order to solve this differential equation you look at it till a
solution occurs to you."
"This principle is so perfectly general that no particular application of
it is possible."
"Geometry is the science of correct reasoning on incorrect figures."
"My method to overcome a difficulty is to go round it."
"What is the difference between method and device? A method is a device
which you used twice."
