A quotation for today

Felix Klein (1849 - 1925)

Everyone knows what a curve is, until he has studied enough mathematics to become confused through the countless number of possible exceptions.

Quoted in C B Boyer, The Invention of Analytic Geometry, Scientific American 180 (1949)

Another quotation by one of today's mathematicians
