Giuseppe Peano Konrad Knopp

Theorem of the day from Robin Whitty

A quotation for today

Giuseppe Peano (1858 - 1932)

Questions that pertain to the foundations of mathematics, although treated by many in recent times, still lack a satisfactory solution. The difficulty has its main source in the ambiguity of language.

Opening of the paper Arithmetices principia in which he introduced axioms for the integers.

Another quotation by one of today's mathematicians
