There are many memorable quotations pertaining to mathematics, from mathematicians, scientists, artists, etc. The following small sampling is organized by what kind of person said the given quote, with first priority given to mathematicians.

Mathematicians

``God made the integers, and all the rest is the work of man.''

``A mathematician is a device for turning coffee into theorems.''

Philosophers

``Mathematics possesses not only truth, but supreme beauty -- a beauty cold and austere, like that of sculpture.''

``Mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true.''

Physicists

``As far as the laws of mathematics refer to reality, they are not certain, and as far as they are certain, they do not refer to reality.''

Politicians

``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: and how the one step involved all the others. It was like politics. But it was after dinner and I let it go!''

Fictional characters

``Math, my dear boy, is nothing more than the lesbian sister of biology.''

``How about we fire up the old Segway and find a nice quiet field to do long division in? I mean, a nice quiet field in which to do long division. Sorry, sorry, everybody.''
