Alfred North Whitehead

There is no getting out of it. Through and through the world is infected with quantity. To talk sense is to talk in quantities. . . . You cannot evade quantity. You may fly to poetry and to music, and quantity and number will face you in your rhythms and your octaves. Elegant intellects which despise the theory of quantity are but half developed. They are more to be pitied than blamed.

The Aims of Education, 1917

Kline, Morris

A proof tells us where to concentrate our doubts.


Kline, Morris

Statistics: the mathematical theory of ignorance.


Arthur Koestler (1905-1983)

Nobody before the Pythagoreans had thought that mathematical relations held the secret of the universe. Twenty-five centuries later, Europe is still blessed and cursed with their heritage. To non-European civilizations, the idea that numbers are the key to both wisdom and power, seems never to have occurred.


Arthur Koestler (1905-1983)

In the index to the six hundred odd pages of Arnold Toynbee's A Study of History, abridged version, the names of Copernicus, Galileo, Descartes and Newton do not occur yet their cosmic quest destroyed the medieval vision of an immutable social order in a walled-in universe and transformed the European landscape, society, culture, habits and general outlook, as thoroughly as if a new species had arisen on this planet.


Sofya Kovalevskaya

Say what you know, do what you must, come what may.


Sofya Kovalevskaya

Many people who have never had occasion to learn what mathematics is confuse it with arithmetic and consider it a dry and arid science. In actual fact it is the science which demands the utmost imagination. One of the foremost mathematicians of our century says very justly that it is impossible to be a mathematician without also being a poet in spirit. . . . It seems to me that the poet must see what others do not see, must see more deeply than other people. And the mathematician must do the same.


Prinz zu Hohlenlohe-Ingelfingen Kraft (1827-1892)

Mathematics is indeed dangerous in that it absorbs students to such a degree that it dulls their senses to everything else.


Kronecker, Leopold (1823 - 1891)

God made the integers, all else is the work of man.


Kronecker, Leopold (1823-1891)

Number theorists are like lotus-eaters -- having once tasted of this food they can never give it up.
