Mathematicians Of The Day
22nd September
This day in 1792 was proposed by Jérôme Lalande as the first day of the French Revolutionary Calendar. By coincidence, it coincided with the autumn equinox.
The postage stamp of one of today's mathematicians at THIS LINK was issued in 1991.
Thus, the sun illuminated both poles simultaneously, and in succession the entire globe, on the same day that, for the first time, in all its purity, the flame of liberty, which must one day illuminate all mankind, shone on the French nation.See THIS LINK.

Quotation of the day
From Michael Faraday
Gravity. Surely this force must be capable of an experimental relation to electricity, magnetism, and the other forces, so as to bind it up with them in reciprocal action and equivalent effect.
