“In a way, mathematics is the only infinite human activity. It is conceivable that humanity could eventually learn everything in physics or biology. But humanity certainly won't ever be able to find out everything in mathematics, because the subject is infinite. Numbers themselves are infinite. That's why mathematics is really my only interest.”
― Paul Erdős

“Mathematical truth is immutable; it lies outside physical reality... This is our belief; this is our core motivating force.”
― Joel Spencer

“Mathematicians need only peace of mind and occasionally, paper and pencil.”
― Paul Hoffman, The Man Who Loved Only Numbers: The Story of Paul Erdős and the Search for Mathematical Truth

“Reductio ad absurdum, which Euclid loved so much, is one of a mathematician's finest weapons. It is a far finer gambit than any chess play: a chess player may offer the sacrifice of a pawn or even a piece, but a mathematician offers the game.”
― G.H. Hardy, A Mathematician's Apology
