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.

As far as the laws of mathematics refer to reality, they are not certain, and as far as they are certain, they do not refer to reality.
Albert EinsteinGood, he did not have enough imagination to become a mathematician.
david hilbertI have hardly ever known a mathematician who was capable of reasoning.
PlatoMathematics is not a careful march down a wellcleared highway, but a journey into a strange wilderness, where the explorers often get lost. Rigour should be a signal to the historian that the maps have been made, and the real explorers have gone elsewhere.
If 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.
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!
What has philosophy got to do with measuring anything? It's the mathematicians you have to trust, and they measure the skies like we measure a field.
Galileo GalileiArchimedes 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.
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 the bold luxury of pure reason, one of the few that remain today.
[Mathematics is] the science that draws necessary conclusions.
Number is the ruler of forms and ideas, and the cause of gods and daemons .
There is geometry in the humming of the strings, there is music in the spacing of the spheres.
Extension and abstraction without apparent direction or purpose is fundamental to the discipline. Applicability is not the reason we work, and plenty that is not applicable contributes to the beauty and magnificence of our subject.
Peter RowlettTrying 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.
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 WhiteheadYeah, 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.
