Progress in science is often built on wrong theories that are later co — Freeman Dyson

"I am content to be one of the multitude of Christians who do not care much about the doctrine of the Trinity or the historical truth of the gospels. Both as a scientist and as a religious person, I am accustomed to living with uncertainty. Science is exciting because it is full of unsolved mysteries, and religion is exciting for the same reason. The greatest unsolved mysteries are the mysteries of our existence as conscious beings in a small corner of a vast universe."

"It has been generally believed that only the complex numbers could legitimately be used as the ground field in discussing quantum-mechanical operators. Over the complex field, Frobenius theorem is of course not valid; the only division algebra over the complex field is formed by the complex numbers themselves. However, Frobenius theorem is relevant precisely because the appropriate ground field for much of quantum mechanics is real rather than complex."

"Scientifically speaking, a butterfly is at least as mysterious as a superstring. When something ceases to be mysterious it ceases to be of absorbing interest to scientists. Almost all things scientists think and dream about are mysterious."

"There’s very good news from the asteroids. It appears that a large fraction of them, including the big ones, are actually very rich in H2O. Nobody imagined that. They thought they were just big rocks … It’s easier to get to an asteroid than to Mars, because the gravity is lower and landing is easier. Certainly the asteroids are much more practical, right now. If we start space colonies in, say, the next 20 years, I would put my money on the asteroids."

"We must be careful not to discourage our twelve-year-olds by making them waste the best years of their lives preparing for examinations."

"The public has a distorted view of science, because children are taught in school that science is a collection of firmly established truths. In fact, science is not a collection of truths. It is a continuing exploration of mysteries. (New York Review of Books, 2011)"

"The absolute requisites for the study of this work... are a knowledge of algebra to the binomial at least, plane and solid geometry, plane trigonometry, and the most simple part of the usual applications of algebra to geometry. ...A. De Morgan. London July 1, 1836"

"Captain Littlepage had overset his mind with too much reading."

"What say you? It is useless? Ay, I know But who fights ever hoping for success? I fought for lost cause, and for fruitless quest! You there, who are you! — You are thousands! Ah! I know you now, old enemies of mine! Falsehood! Have at you! Ha! and Compromise! Prejudice, Treachery! … Surrender, I? Parley? No, never! You too, Folly, — you? I know that you will lay me low at last; Let be! Yet I fall fighting, fighting still!"

"Ive been taking a closer look at these graduates. They are actually taller, stronger, smarter than we were, smart enough maybe to take our mistakes as their messages, to make our weaknesses their lessons, and to make our example — good and not so good — part of their education."

"In short, it is not merely that Johnny cant read, or even that Johnny cant think. Johnny doesnt know what thinking is, because thinking is so often confused with feeling in many public schools. [emphasis in the original]"

"Bigotry is the disease of ignorance, of morbid minds; enthusiasm of the free and buoyant. Education & free discussion are the antidotes of both."
