Mathematicians Of The Day

4th April

Quotation of the day

From Benjamin Peirce
[after proving Euler's formula eπ i = -1 in a lecture]
Gentlemen, that is surely true, it is absolutely paradoxical; we cannot understand it, and we don't know what it means. But we have proved it, and therefore we know it is the truth.
Quoted in E Kasner and J Newman Mathematics and the Imagination (New York 1940)
