Mathematicians Of The Day

27th December



On this day in 1725, Christian Goldbach was the recording secretary at the opening session of the St Petersburg Academy. The form of the Academy was imported ready-made from the Berlin model proposed to Peter the Great by Leibniz several years earlier.

On this day in 2013 Google released a Kepler doodle.

The postage stamp of one of today's mathematicians at THIS LINK was issued in 1953.

Quotation of the day

From Johannes Kepler
On one of Galileo's opponents:

...repudiato mundo sensibili, quem nec ipse vidit, nec expertis credit, ratiunculis puerilibus spaciatur Peripateticus in mundo chartaceo, negatque Solem lucere, quia ipse coecus est.

[... repudiating the sensible world, which he neither sees himself nor believes from those who have, the Peripatetic [follower of Aristotle] joins combat by childish quibbling in a world on paper, and denies the Sun shines because he himself is blind.]
Kepler to Galileo Galilei, 28 March 1611, Letter 611, ll. 17 - 20, KGW 16 372.
Note: Galileo later used the phrase a world on paper and it is sometimes ascribed to him.
