When I was a boy of 14, my father was so ignorant I could hardly stand to have the old man around. But when I got to 21, I was astonished at how much the old man had learned in 7 years. -- Mark Twain

I have often pondered over the roles of knowledge or experience, on the one hand, and imagination or intuition, on the other, in the process of discovery. I believe that there is a certain fundamental conflict between the two, and knowledge, by advocating caution, tends to inhibit the flight of imagination. Therefore, a certain naivete, unburdened by conventional wisdom, can sometimes be a positive asset.
-- Harish Chandra (Mathematician)

"There are two kinds of paradoxes. They are not so much the good and the bad, nor even the true and the false.

"A queer and almost mad notion seems to have got into the modern head that, if you mix up everybody and everything more or less anyhow, the mixture may be called unity, and the unity may be called peace.

"Mathematics is the science which uses easy words for hard ideas." -- Edward Kasner and James R. Newman

"Ah, women. They make the highs higher and the lows more frequent." Friedrich Nietzsche

"[Paradoxes of the infinite arise] only when we attempt, with our finite minds, to discuss the infinite, assigning to it those properties which we give to the finite and limited;" -- Galileo Galilei

"Bees … by virtue of a certain geometrical forethought … know that the hexagon is greater than the square and the triangle, and will hold more honey for the same expenditure of material." -- Pappas

"How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth?" -- Sir Arthur Conan Doyle

"It is the supreme art of the teacher to awaken joy in creative expression and knowledge." -- Albert Einstein

"I have no particular talent. I am only inquisitive." -- Albert Einstein

"In the beginning (if there was such a thing), God created Newton’s laws of motion together with the necessary masses and forces. This is all; everything beyond this follows from the development of appropriate mathematics methods by means of deduction." -- Albert Einstein

"It will be another million years, at least, before we understand the primes." - Paul Erdos

"Science and art sometimes can touch one another, like two pieces of the jigsaw puzzle which is our human life, and that contact may be made across the borderline between the two respective domains."-- M.C. Escher

"Father [M.C. Escher] had difficulty comprehending that the working of his mind was akin to that of a mathematician. He greatly enjoyed the interest in his work by mathematicians and scientists, ..." -- George Escher

"For since the fabric of the universe is most perfect and the work of a most wise Creator, nothing at all takes place in the universe in which some rule of maximum or minimum does not appear." -- Leonhard Euler

"Mathematics serves as a handmaiden for the explanation of the quantitative situations in other subjects, such as economics, physics, navigation, finance, biology and even the arts." -- H. F. Feh
"The journey for an education starts with a childhood question."-- David L. Finn

"Mathematics compares the most diverse phenomena and discovers the secret analogies that unite them." -- Joseph Fourier

"The deep study of nature is the most fruitful source of mathematical discoveries." -- Jean-Baptist-Joseph Fourier

"What science can there be more noble, more excellent, more useful for men, more admirably high and demonstrative, than this of mathematics?" -- Benjamin Franklin

"In most sciences one generation tears down what another has built and what one has established another undoes. In mathematics alone each generation adds a new story to the old structure." -- Herman Henkel

“Before beginning [to try to prove Fermat's Last Theorem] I should have to put in three years of intensive study, and I haven't that much time to squander on a probable failure." -- David Hilbert

"The infinite in mathematics is always unruly unless it is properly treated." -- Edward Kasner and James Newman

"Among all of the mathematical disciplines the theory of differential equations is the most important... It furnishes the explanation of all those elementary manifestations of nature which involve time." -- Sophus Lie

"If you hold yourself up to your children, hold yourself up as an object lesson and not as an example." -- George Bernard Shaw

"Mathematics, in the common lay view, is a static discipline based on formulas...But outside the public view, mathematics continues to grow at a rapid rate...the guide to this growth is not calculation and formulas, but an open ended search for pattern." -- Lynn A. Steen

"What humans do with the language of mathematics is to describe patterns..." -- Lynn A. Steen
"Symmetry, as wide or as narrow as you define its meaning, is one idea by which man through the ages has tried to comprehend and create order, beauty and perfection." -- Hermann Weyl

"A mathematician's reputation rests on the number of bad proofs he has given." -- A. S. Besicovitch

"Poetry is as exact a science as geometry." -- Gustave Flaubert

“There still remain three studies suitable for free man. Arithmetic is one of them." -- Plato

"God grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference." -- Reinhold Niebuhr
