Not everything that can be counted counts, and not everything that counts can be counted.
Albert Einstein quotes

I guess I think of lotteries as a tax on the mathematically challenged.
Roger Jones quotes

1) Numbers are tools, not rules. 2) Numbers are symbols for things; the number and the thing are not the same. 3) Skill in manipulating numbers is a talent, not evidence of divine guidance. 4) Like other occult techniques of divination, the statistical method has a private jargon deliberately contrived to obscure its methods from nonpractitioners. 5) The product of an arithmetical computation is the answer to an equation; it is not the solution to a problem. 6) Arithmetical proofs of theorems that do not have arithmetical bases prove nothing.
Ashley-Perry Statistical Axioms quotes

2 is not equal to 3 - not even for very large values of 2.
Grabel's Law quotes

Variables won't, constants aren't.
Osborn's Law quotes

Women have a passion for mathematics. They divide their age in half, double the price of their clothes, and always add at least five years to the age of their best friend.
Marcel Achard quotes

I was x years old in the year x^2. (when asked his age.)
Augustus de Morgan quotes

Thus, be it understood, to demonstrate a theorem, it is neither necessary nor even advantageous to know what it means.
Henri Poincare quotes

God exists since mathematics is consistent, and the Devil exists since we cannot prove it.
Andre Weil quotes

Twelve for 23... It doesn't take a genius to see that's under 50 percent.
Dick Vitale quotes

Have you noticed that the astronomers and mathematicians are much the most cheerful people of the lot? I suppose that perpetually contemplating things on so vast a scale makes them feel either that it doesn't matter a hoot anyway, or that anything so large and elaborate must have some sense in it somewhere.
Dorothy L. Sayers quotes

It is easier to square the circle than to get round a mathematician.
Augustus de Morgan quotes

The good Christian should beware of mathematicians, and all those who make empty prophecies. The danger already exists that the mathematicians have made a covenant with the devil to darken the spirit and to confine man in the bonds of Hell.
Saint Augustine quotes
