**Galbraith, John Kenneth**There can be no question, however, that prolonged commitment to mathematical exercises in economics can be damaging. It leads to the atrophy of judgement and intuition…

*Economics, Peace, and Laughter.*

**Galilei, Galileo (1564 – 1642)**[The universe] cannot be read until we have learnt the language and become familiar with the characters in which it is written. It is written in mathematical language, and the letters are triangles, circles and other geometrical figures, without which means it is humanly impossible to comprehend a single word.

*Opere Il Saggiatore*p. 171.

**Galilei, Galileo (1564 – 1642)**Measure what is measurable, and make measurable what is not so.

Quoted in H. Weyl “Mathematics and the Laws of Nature” in I Gordon and S. Sorkin (eds.)

*The Armchair Science Reader*, New York: Simon and Schuster, 1959.

**Galilei, Galileo (1564 – 1642)**And who can doubt that it will lead to the worst disorders when minds created free by God are compelled to submit slavishly to an outside will? When we are told to deny our senses and subject them to the whim of others? When people devoid of whatsoever competence are made judges over experts and are granted authority to treat them as they please? These are the novelties which are apt to bring about the ruin of commonwealths and the subversion of the state.

**Galois, Evariste**Unfortunately what is little recognized is that the most worthwhile scientific books are those in which the author clearly indicates what he does not know; for an author most hurts his readers by concealing difficulties.

*The Life and Labours of Francis Galton*, 1914.

**Galton, Sir Francis (1822-1911)**I know of scarcely anything so apt to impress the imagination as the wonderful form of cosmic order expressed by the “Law of Frequency of Error.” The law would have been personified by the Greeks and deified, if they had known of it. It reigns with serenity and in complete self-effacement, amidst the wildest confusion. The huger the mob, and the greater the apparent anarchy, the more perfect is its sway. It is the supreme law of Unreason. Whenever a large sample of chaotic elements are taken in hand and marshaled in the order of their magnitude, an unsuspected and most beautiful form of regularity proves to have been latent all along.

In J. R. Newman (ed.)

*The World of Mathematics*, New York: Simon and Schuster, 1956. p. 1482.

**Gardner, Martin**Biographical history, as taught in our public schools, is still largely a history of boneheads: ridiculous kings and queens, paranoid political leaders, compulsive voyagers, ignorant generals — the flotsam and jetsam of historical currents. The men who radically altered history, the great scientists and mathematicians, are seldom mentioned, if at all.

*Calculus Gems*, New York: McGraw Hill, 1992.

**Gardner, Martin**Mathematics is not only real, but it is the only reality. That is that entire universe is made of matter, obviously. And matter is made of particles. It’s made of electrons and neutrons and protons. So the entire universe is made out of particles. Now what are the particles made out of? They’re not made out of anything. The only thing you can say about the reality of an electron is to cite its mathematical properties. So there’s a sense in which matter has completely dissolved and what is left is just a mathematical structure.

**Gauss, Karl Friedrich (1777-1855)**I confess that Fermat’s Theorem as an isolated proposition has very little interest for me, because I could easily lay down a multitude of such propositions, which one could neither prove nor dispose of.

[A reply to Olbers’ attempt in 1816 to entice him to work on Fermat’s Theorem.] In J. R. Newman (ed.)

*The World of Mathematics*, New York: Simon and Schuster, 1956. p. 312.

**Gauss, Karl Friedrich (1777-1855)**If others would but reflect on mathematical truths as deeply and as continuously as I have, they would make my discoveries.

In J. R. Newman (ed.)

*The World of Mathematics*, New York: Simon and Schuster, 1956. p. 326.

**Gauss, Karl Friedrich (1777-1855)**There are problems to whose solution I would attach an infinitely greater importance than to those of mathematics, for example touching ethics, or our relation to God, or concerning our destiny and our future; but their solution lies wholly beyond us and completely outside the province of science.

In J. R. Newman (ed.)

*The World of Mathematics*, New York: Simon and Schuster, 1956. p. 314.

**Gauss, Karl Friedrich (1777-1855)**You know that I write slowly. This is chiefly because I am never satisfied until I have said as much as possible in a few words, and writing briefly takes far more time than writing at length.

In G. Simmons

*Calculus Gems*, New York: McGraw Hill inc., 1992.

**Gauss, Karl Friedrich (1777-1855)**God does arithmetic.

**Gauss, Karl Friedrich (1777-1855)**We must admit with humility that, while number is purely a product of our minds, space has a reality outside our minds, so that we cannot completely prescribe its properties a priori.

Letter to Bessel, 1830.

**Gauss, Karl Friedrich (1777-1855)**I mean the word proof not in the sense of the lawyers, who set two half proofs equal to a whole one, but in the sense of a mathematician, where half proof = 0, and it is demanded for proof that every doubt becomes impossible.

In G. Simmons

*Calculus Gems*, New York: McGraw Hill inc., 1992.

**Gauss, Karl Friedrich (1777-1855)**I have had my results for a long time: but I do not yet know how I am to arrive at them.

In A. Arber

*The Mind and the Eye*1954.

**Gauss, Karl Friedrich (1777-1855)**[His motto:]

Few, but ripe.

**Gauss, Karl Friedrich (1777-1855)**[His second motto:]

Thou, nature, art my goddess; to thy laws my services are bound…

W. Shakespeare

*King Lear*.

**Gauss, Karl Friedrich (1777-1855)**[attributed to him by H.B Lübsen]

Theory attracts practice as the magnet attracts iron.

Foreword of H.B Lübsen’s geometry textbook.

**Gauss, Karl Friedrich (1777-1855)**It is not knowledge, but the act of learning, not possession but the act of getting there, which grants the greatest enjoyment. When I have clarified and exhausted a subject, then I turn away from it, in order to go into darkness again; the never-satisfied man is so strange if he has completed a structure, then it is not in order to dwell in it peacefully, but in order to begin another. I imagine the world conqueror must feel thus, who, after one kingdom is scarcely conquered, stretches out his arms for others.

Letter to Bolyai, 1808.

**Gauss, Karl Friedrich (1777-1855)**Finally, two days ago, I succeeded – not on account of my hard efforts, but by the grace of the Lord. Like a sudden flash of lightning, the riddle was solved. I am unable to say what was the conducting thread that connected what I previously knew with what made my success possible.

In H. Eves

*Mathematical Circles Squared*, Boston: Prindle, Weber and Schmidt, 1972.

**Gauss, Karl Friedrich (1777-1855)**A great part of its [higher arithmetic] theories derives an additional charm from the peculiarity that important propositions, with the impress of simplicity on them, are often easily discovered by induction, and yet are of so profound a character that we cannot find the demonstrations till after many vain attempts; and even then, when we do succeed, it is often by some tedious and artificial process, while the simple methods may long remain concealed.

In H. Eves

*Mathematical Circles Adieu*, Boston: Prindle, Weber and Schmidt, 1977.

**Gauss, Karl Friedrich (1777-1855)**I am coming more and more to the conviction that the necessity of our geometry cannot be demonstrated, at least neither by, nor for, the human intellect…geometry should be ranked, not with arithmetic, which is purely aprioristic, but with mechanics.

Quoted in J. Koenderink

*Solid Shape*, Cambridge Mass.: MIT Press, 1990.

**Gay, John**Lest men suspect your tale untrue,

Keep probability in view.

*The World of Mathematics*, New York: Simon and Schuster, 1956. p. 1334.

**Gibbs, Josiah Willard (1839 – 1903)**One of the principal objects of theoretical research in my department of knowledge is to find the point of view from which the subject appears in its greatest simplicity.

**Gibbs, Josiah Willard (1839-1903)**Mathematics

*is*a language.

**Gilbert, W. S. (1836 – 1911)**I’m very good at integral and differential calculus, I know the scientific names of beings animalculous; In short, in matters vegetable, animal, and mineral, I am the very model of a modern Major-General.

*The Pirates of Penzance.*Act 1.

**Glaisher, J.W.**

The mathematician requires tact and good taste at every step of his work, and he has to learn to trust to his own instinct to distinguish between what is really worthy of his efforts and what is not.

In H. Eves

*Mathematical Circles Squared*, Boston: Prindle, Weber and Schmidt, 1972.

**Glanvill, Joseph**

And for mathematical science, he that doubts their certainty hath need of a dose of hellebore.

In J. R. Newman (ed.)

*The World of Mathematics*, New York: Simon and Schuster, 1956, p. 548.

**Goedel, Kurt**

I don’t believe in natural science.

[Said to physicist John Bahcall.]

Ed Regis,

*Who Got Einstein’s Office?*Addison Wesley, 1987.

**Goethe**It has been said that figures rule the world. Maybe. But I am sure that figures show us whether it is being ruled well or badly.

In J. P. Eckermann,

*Conversations with Goethe.*

**Goethe**Mathematics has the completely false reputation of yielding infallible conclusions. Its infallibility is nothing but identity. Two times two is not four, but it is just two times two, and that is what we call four for short. But four is nothing new at all. And thus it goes on and on in its conclusions, except that in the higher formulas the identity fades out of sight.

In J. R. Newman (ed.)

*The World of Mathematics*, New York: Simon and Schuster, 1956, p. 1754.

**Goodman, Nicholas P.**There are no deep theorems — only theorems that we have not understood very well.

*The Mathematical Intelligencer*, vol. 5, no. 3, 1983.

**Gordon, P**This is not mathematics, it is theology.

[On being exposed to Hilbert’s work in invariant theory.]

Quoted in P. Davis and R. Hersh

*The Mathematical Experience*, Boston: Birkhäuser, 1981.

**Graham, Ronald**It wouild be very discouraging if somewhere down the line you could ask a computer if the Riemann hypothesis is correct and it said, `Yes, it is true, but you won’t be able to understand the proof.’

John Horgan.

*Scientific American*269:4 (October 1993) 92-103.

**Grünbaum, Branko (1926 – ), and Shephard, G. C. (?)**Mathematicians have long since regarded it as demeaning to work on problems related to elementary geometry in two or three dimensions, in spite of the fact that it it precisely this sort of mathematics which is of practical value.
