“It may be appropriate to quote a statement of Poincare, who said (partly in jest no doubt) that there must be something mysterious about the normal law since mathematicians think it is a law of nature whereas physicists are convinced that it is a mathematical theorem.” HumorFunnyScienceNatureMysteryMathematicsMathLaws Of NatureLaws Of PhysicsPhysicistsMathematiciansTheoremHenri PoincaréPoincaré Book:Statistical Independence in Probability, Analysis, and Number Theory Source: Statistical Independence in Probability, Analysis, and Number Theory
“To exist (in mathematics), said Henri Poincaré, is to be free from contradiction. But mere existence does not guarantee survival. To survive in mathematics requires a kind of vitality that cannot be described in purely logical terms.” KindDoeSaidTermExistenceSurvivalMathematicsMereGuaranteesContradictionLogicalVitality Book:Mathematics and Logic Source: Mathematics and Logic

“... there are those who believe that mathematics can sustain itself and grow without any further contact with anything outside itself, and those who believe that nature is still and always will be one of the main (if not the main) sources of mathematical inspiration. The first group is identified as "pure mathematicians" (though "purist" would be more adequate) while the second is, with equal inadequacy, referred to as "applied".” IfsFirstsBelieveStillsInspirationWould BeGrowsGroupsSourcePureEqualMathematicsContactMathematicalMathematicianAdequateInadequacy Author:Mark Kac
