Mathematicians Of The Day

13th June



On this day in 1771, Lagrange presented the first proof of Wilson's theorem to the Berlin Academy:-
A number p is prime if and only if 1+(p1)!1 + (p - 1)! is divisible by p.
Edward Waring published the theorem in 1770, but Leibniz knew it previously.

The postage stamp of one of today's mathematicians at THIS LINK was issued in 1991.

Quotation of the day

From James Clerk Maxwell
My soul is an entangled knot,
Upon a liquid vortex wrought
By Intellect in the Unseen residing,
And thine doth like a convict sit,
With marline-spike untwisting it,
Only to find its knottiness abiding;
Since all the tools for its untying
In four-dimensional space are lying,
Wherein they fancy intersperses
Long avenues of universes,
While Klein and Clifford fill the void
With one finite, unbounded homoloid,
And think the Infinite is now at last destroyed.
