Maths is the purest science in that you don't need any test tubes or animal testing to do it. All the other sciences eventually boil down to maths, apart from biology, which boils down to soup.

Good, he did not have enough imagination to become a mathematician.
david hilbertConcern for the symbol has completely disappeared from our science. And yet, if one were to give oneself the trouble, one could easily find, in certain parts at least of contemporary mathematics... symbols as clear, as beautiful, and as full of spiritual meaning as that of the circle and mediation. From modern thought to ancient wisdom the path would be short and direct, if one cared to take it.
Simone WeilI have hardly ever known a mathematician who was capable of reasoning.
PlatoGod used beautiful mathematics in creating the world.
paul diracIf in other sciences we should arrive at certainty without doubt and truth without error, it behooves us to place the foundations of knowledge in mathematics.
The study of mathematics is the indispensable basis for all intellectual and spiritual progress.
Mathematics is not something that you find lying around in your back yard. It’s produced by the human mind. Yet if we ask where mathematics works best, it is in areas like particle physics and astrophysics, areas of fundamental science that are very, very far removed from everyday affairs.
As to your Newton, I confess I do not understand his void and his gravity; I admit he has demonstrated the movement of the heavenly bodies with more exactitude than his forerunners; but you will admit it is an absurdity to to maintain the existence of Nothing.
Euler calculated the force of the wheels necessary to raise the water in a reservoir … My mill was carried out geometrically and could not raise a drop of water fifty yards from the reservoir. Vanity of vanities! Vanity of geometry!
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.
From the intrinsic evidence of his creation, the Great Architect of the Universe now begins to appear as a pure mathematician.
It is a wellknown experience that the only truly enjoyable and profitable way of studying mathematics is the method of "filling in details" by one's own efforts.
There is no branch of mathematics, however abstract, which may not some day be applied to phenomena of the real world.
Theorems often tell us complex truths about the simple things, but only rarely tell us simple truths about the complex ones. To believe otherwise is wishful thinking or "mathematics envy."
Mathematics is good for the soul, getting things right enlivens a sense of truth, efforts to understand automatically purify desires.
Mathematics is the source of a wicked intellect that, while making man the lord of the earth, also makes him the slave of the machine.
robert musilMathematics is the bold luxury of pure reason, one of the few that remain today.
Trying to solve realworld problems, researchers often discover that the tools they need were developed years, decades or even centuries earlier by mathematicians with no prospect of, or care for, applicability.
Mathematics takes us still further from what is human, into the region of absolute necessity, to which not only the world, but every possible world, must conform.
bertrand russellI like mathematics because it is not human and has nothing particular to do with this planet or with the whole accidental universe – because, like Spinoza's God, it won't love us in return.
By relieving the brain of all unnecessary work, a good notation sets it free to concentrate on more advanced problems, and in effect increases the mental power of the race.
Alfred North WhiteheadThe land of easy mathematics where he who works adds up and he who retires subtracts.
Yeah, Silver and his math are jokes, because math has a liberal bias. After all, math is the reason Mitt Romney's tax plan doesn't add up.
stephen colbertAs long as algebra is taught in school, there will be prayer in school.
Cokie RobertsOur offense is like the pythagorean theorem: There is no answer!
