## A Quote by Nikola Tesla on science, mathematics, theory, and nature

Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality. — Nikola Tesla, Modern Mechanics and Inventions, July, 1934 US (Serbian-born) electrical inventor (1857 - 1943)

## A Quote by Bertrand Russel on physics, mathematics, physical world, properties, and discover

Physics is mathematical not because we know so much about the physical world, but because we know so little: it is only its mathematical properties that we can discover

## A Quote by Charles Robert Darwin on math, mathematics, and mathematician

A mathematician is a blind man in a dark room looking for a black cat that isn't there.

## A Quote by Woody Allen on discovery, mathematics, students, and writing

Standard mathematics has recently been rendered obsolete by the discovery that for years we have been writing the numeral five backward. This has led to reevaluation of counting as a method of getting from one to ten. Students are taught advanced concepts of Boolean algebra, and formerly unsolvable equations are dealt with by threats of reprisals.

## A Quote by Sir Winston Leonard Spencer Churchill on argument, certainty, conviction, day, discovery, doubt, education, existence, facts, friendship, hell, independence, machines, mathematics, military, persistence, play, purity, purpose, reality, reason,

Some of my cousins who had the great advantage of University education used to tease me with arguments to prove that nothing has any existence except what we think of it. . . . These amusing mental acrobatics are all right to play with. They are perfectly harmless and perfectly useless. . . . I always rested on the following argument. . . We look up to the sky and see the sun. Our eyes are dazzled and our senses record the fact. So here is this great sun standing apparently on no better foundation than our physical senses. But happily there is a method, apart altogether from our physical senses, of testing the reality of the sun. It is by mathematics. By means of prolonged processes of mathematics, entirely separate from the senses, astronomers are able to calculate when an eclipse will occur. They predict by pure reason that a black spot will pass across the sun on a certain day. You go and look, and your sense of sight immediately tells you that their calculations are vindicated. So here you have the evidence of the senses reinforced by the entirely separate evidence of a vast independent process of mathematical reasoning. We have taken what is called in military map-making "a cross bearing." . . . When my metaphysical friends tell me that the data on which the astronomers made their calculations, were necessarily obtained originally through the evidence of the senses, I say, "no." They might, in theory at any rate, be obtained by automatic calculating-machines set in motion by the light falling upon them without admixture of the human senses at any stage. When it is persisted that we should have to be told about the calculations and use our ears for that purpose, I reply that the mathematical process has a reality and virtue in itself, and that once discovered it constitutes a new and independent factor. I am also at this point accustomed to reaffirm with emphasis my conviction that the sun is real, and also that it is hot - in fact hot as Hell, and that if the metaphysicians doubt it they should go there and see.

## A Quote by Sir Winston Leonard Spencer Churchill on feeling and mathematics

I had a feeling once about Mathematics - that I saw it all. Depth beyond depth was revealed to me - the Byss and Abyss. I saw - as one might see the transit of Venus or even the Lord Mayor's Show - a quantity passing through infinity and changing its sign from plus to minus. I saw exactly why it happened and why the tergiversation was inevitable - but it was after dinner and I let it go.

## A Quote by W. S. Anglin on journeys, losing, mathematics, and wilderness

Mathematics is not a careful march down a well-cleared highway, but a journey into a strange wilderness, where the explorers often get lost. Rigour should be a signal to the historian that the maps have been made, and the real explorers have gone elsewhere.
