Mathematicians Of The Day

20th October

On this day in 1939 the three Polish mathematicians Rejewski, Rozycki and Zygalski began decoding German Enigma cipher messages from a station near Paris. World War II had begun about two weeks earlier.

On this day in 2014 Google released a Wren doodle.

Quotation of the day

From Paul Dirac
I learned to distrust all physical concepts as the basis for a theory. Instead one should put one's trust in a mathematical scheme, even if the scheme does not appear at first sight to be connected with physics. One should concentrate on getting interesting mathematics.
