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
In order to obtain physical ideas without adopting a physical theory we must make ourselves familiar with the existence of physical analogies. By a physical analogy I mean that partial similarity between the laws of one science and those of another which makes each of them illustrate the other. Thus all the mathematical sciences are founded on relations between physical laws and laws of. numbers, so that the aim of exact science is to reduce the problems of nature to the determination of quantities by operations with numbers.
On Faraday's Lines of Force (1856).
