Mathematicians Of The Day

14th December

On this day in 1900, Max Planck presented his theoretical explanation involving quanta of energy at a meeting of the Physikalische Gesellschaft in Berlin. In doing so he had to reject his belief that the second law of thermodynamics was an absolute law of nature, and accept Boltzmann's interpretation that it was a statistical law.

On this day in 2013 Google released a Brahe doodle.

Quotation of the day

From Tycho Brahe
Now it is quite clear to me that there are no solid spheres in the heavens, and those that have been devised by authors to save the appearances, exist only in their imagination, for the purpose of permitting the mind to conceive the motion which the heavenly bodies trace in their courses.
Quoted in A L Mackay, Dictionary of Scientific Quotations (London 1994)
