## Mathematicians Of The Day

### 14th January

On this day in 1858, Arthur Cayley's

*A Memoir on the Theory of Matrices*was read at the Royal Society. Cayley established rules of notation and operations for these newly emerging ideas in mathematics. This paper also contained the first formal statement of what we now call the Cayley-Hamilton Theorem.
