Mathematicians Of The Day

3rd February

On this day in 1851, Léon Foucault demonstrated his pendulum in the Paris Observatory. The demonstration was a complete success. A paper by Foucault on his pendulum was read by Arago to the Academy of Sciences on the same day as the experiment was carried out in the Observatory.

Quotation of the day

From Oliver Heaviside
There is no absolute scale of size in the Universe, for it is boundless towards the great and also boundless towards the small.
Quoted in D'A W Thompson On Growth and Form (Cambridge 1917)
