Quotation of the day

From Stan Ulam
To exist (in mathematics), said Henri Poincaré, is to be free from contradiction. But mere existence does not guarantee survival. To survive in mathematics requires a kind of vitality that cannot be described in purely logical terms.
Mark Kac and Stanislaw Ulam, Mathematics and Logic (1968)
