The chemist smiles at the childish efforts of alchemists but the mathematician finds the geometry of the Greeks and the arithmetic of the Hindoos as useful and admirable as any research of today.

Every mathematician knows it is impossible to understand an elementary course in thermodynamics.
A mathematician is a blind man in a dark room looking for a black cat which isn't there.
A mathematician, then, will be defined in what follows as someone who has published the proof of at least one nontrivial theorem.
The mathematician has reached the highest rung on the ladder of human thought.
Havelock EllisDiscovery in mathematics is not a matter of logic. It is rather the result of mysterious powers which no one understands, and in which unconscious recognition of beauty must play an important part. Out of an infinity of designs, a mathematician chooses one pattern for beauty's sake and pulls it down to earth.
marston morseStatistically, it would seem improbable that any mathematician or scientist, at the age of 66, would be able through continued research efforts, to add much to his or her previous achievements. However I am still making the effort and it is conceivable that with the gap period of about 25 years of partially deluded thinking providing a sort of vacation my situation may be atypical. Thus I have hopes of being able to achieve something of value through my current studies or with any new ideas that come in the future.
john forbes nashThe engine driving the Kelly system is the "law of large numbers." In a 1713 treatise on probability, Swiss mathematician Jakob Bernoulli propounded a law that has been misunderstood by gamblers (and investors) ever since.
william poundstoneCarl Friedrich Gauss, often rated the greatest mathematician of all time, played the market. On a salary of 1,000 thalers a year, Euler left an estate of 170,587 thalers in cash and securities. Nothing is known of Gauss's investment methods.
william poundstoneIf we except the great name of Newton (and the exception is one that the great Gauss himself would have been delighted to make) it is probable that no mathematician of any age or country has ever surpassed Gauss in the combination of an abundant fertility of invention with an absolute vigorousness in demonstration...
henry john stephen smithNo one gets angry at a mathematician or a physicist whom he or she doesn't understand at all, or at someone who speaks a foreign language, but rather at someone who tampers with your own language, with this 'relation,' precisely, which is yours.
jacques derridaThe physicists say that I am a mathematician, and the mathematicians say that I am a physicist. I am a completely isolated man and though everybody knows me, there are very few people who really know me.
Albert EinsteinEvery man who is not a monster, a mathematician, or a mad philosopher, is the slave of some woman or other.
george eliotA mathematician is only perfect insofar as he is a perfect man, sensitive to the beauty of truth.
Good, he did not have enough imagination to become a mathematician.
david hilbertAn old French mathematician said: A mathematical theory is not to be considered complete until you have made it so clear that you can explain it to the first man whom you meet on the street. This clearness and ease of comprehension, here insisted on for a mathematical theory, I should still more demand for a mathematical problem if it is to be perfect; for what is clear and easily comprehended attracts, the complicated repels us.
david hilbertI'm sure a mathematician would claim that 0 and 1 are both very interesting numbers.
larry wallA mathematician is a device for turning coffee into theorems.
Such questions, thus too often rejected by the mathematician as metaphysical , are on the other hand discarded by the metaphysician as mathematical: so that, disowned by both, they fall to the ground without any satisfactory discussion at all.
There is a famous formula, perhaps the most compact and famous of all formulas developed by Euler from a discovery of de Moivre: It appeals equally to the mystic, the scientist, the philosopher, the mathematician.
I have hardly ever known a mathematician who was capable of reasoning.
Plato... Norbert Wiener of the Massachusetts Institute of Technology, a brilliant mathematician who recently won fame with his invention of cybernetics, a new science of communications... His prolonged studies of the striking analogies between the control systems in animal bodies and those in complex machines became the basis of his newly created cybernetics, a science of communications.
A scientist worthy of the name, above all a mathematician, experiences in his work the same impression as an artist; his pleasure is as great and of the same nature.
Archimedes will be remembered when Aeschylus is forgotten, because languages die and mathematical ideas do not. "Immortality" may be a silly word, but probably a mathematician has the best chance of whatever it may mean.
A mathematician, like a painter or poet, is a maker of patterns. If his patterns are more permanent than theirs, it is because they are made with ideas.
From the intrinsic evidence of his creation, the Great Architect of the Universe now begins to appear as a pure mathematician.
