## 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 $1 + (p - 1)!$ is divisible by p.Edward Waring published the theorem in 1770, but Leibniz knew it previously.

#### Quotation of the day

##### From James Clerk Maxwell

... that, in a few years, all great physical constants will have been approximately estimated, and that the only occupation which will be left to men of science will be to carry these measurements to another place of decimals.

[Maxwell strongly disagreed with these views and was attacking them.]
