– Dennie L. Van Tassel

It is not unreasonable to use the hypothesis. – Arnold Ross

Science is what we understand well enough to explain to a computer. Art is everything else we do. – Donald Knuth

Understanding is a kind of ecstasy. – Carl Sagan

The greater the difficulty, the more glory in surmounting it. Skillful pilots gain their reputation from storms and tempests. – Epicurus

Example is the school of mankind, and they will learn at no other. – Edmund Burke

Minus times minus is plus. The reason for this we need not discuss. – W.H. Auden

There is no substitute for hard work. – Thomas Alva Edison

Theory is the general; experiments are the soldiers. – Leonardo da Vinci

It looked absolutely impossible. But it so happens that you go on worrying away at a problem in science and it seems to get tired, and lies down and lets you catch it. – William Lawrence Bragg

The secret of science is to ask the right questions, and it is the choice of problem more than anything else that marks the man of genius in the scientific world. – Sir Henry Tizard

Problems worthy of attack prove their worth by hitting back. – Piet Hein

What is the common denominator of intellectual accomplishment? In math, science, economics, history, or any other subject, the answer is the same: great thinkers notice patterns. – David Niven

If at first you do succeed – try to hide your astonishment. – Harry F. Banks

Wit lies in recognizing the resemblance among things which differ and the difference between things which are alike. – Madame de Stael

If I feel unhappy, I do mathematics to become happy. If I am happy, I do mathematics to keep happy. – Paul Turan

The value of a principle is the number of things it will explain. – Ralph Waldo Emerson

No matter how good you are at something, there’s always about a million people better than you. – Homer Simpson

Give me a fruitful error anytime, full of seeds, bursting with its own corrections. You can keep your sterile truth for yourself. – Vilfredo Pareto

I tell them that if they will occupy themselves with the study of mathematics they will find in it the best remedy against the lust of the flesh. – Thomas Mann

The intelligence is proved not by ease of learning, but by understanding what we learn. – Joseph Whitney

I have yet to see any problem, however complicated, which, when you looked at it in the right way, did not become still more complicated. – Paul Anderson

Banach once told me, “Good mathematicians see analogies between theorems or theories, the very best ones see analogies between analogies.” – S.M. Ulam

No pressure, no diamonds. – Mary Case

Hardware: the parts of a computer that can be kicked. – Jeff Pesis

Never underestimate a theorem that counts something. – John Fraleigh

I have always grown from my problems and challenges, from the things that don’t work out. That’s when I’ve really learned. – Carol Burnett

If you don’t learn from your mistakes, there’s no sense making them. – Herbert V. Prochnow

One cannot escape the feeling that these mathematical formulae have an independent existence and an intelligence of their own, that they are wiser than we are, wiser even than their discoverers, that we get more out of them than we originally put into them. – Henrich Hertz

Perhaps the most valuable result of all education is the ability to make yourself do the thing you have to do, when it ought to be done, whether you like it or not. – Thomas Henry Huxley

The greater the difficulty, the more glory in surmounting it. – Epicurus

The important thing in science is not so much to obtain new facts as to discover new ways of thinking about them. – Sir William Lawrence

A mathematician is a machine for turning coffee into theorems. – Paul Erdos

Damn it, if the machine can detect an error, why can’t it locate the position of the error and correct it? – Richard W. Hamming

The New Testament offers the basis for modern computer coding theory, in the form of an affirmation of the binary number system. “But let your communication be yea, yea; nay, nay: for whatsoever is more than these cometh of evil.” – Anonymous

Difficulties should act as a tonic. They should spur us to greater exertion. – B.C. Forbes

Mathematics is not a deductive science–that’s a cliche. When you try to prove a theorem, you don’t just list the hypothesis, and then start to reason. What you do is trial and error, experimentation, guesswork. – Paul Halmos
