## Mathematicians Of The Day

### 23rd March

On this day in 1881, J J Sylvester wrote to Arthur Cayley to announce,

I believe that I have proved Gordan's Theorem, and can assign a superior limit to the number of fundamental invariants.His proof was founded on the prospect that a certain sequence increased without bound. By October he knew that it did not.

#### Quotation of the day

##### From Pierre-Simon Laplace

What we know is not much. What we do not know is immense.

(Allegedly his last words.)
