## Mathematicians Of The Day

### 24th September

On this day in 2017, Maryna Viazovska was given a Clay Research Award in recognition of her groundbreaking work on sphere-packing problems in eight and twenty-four dimensions. In particular, she proved that the $E_8$ lattice is an optimal solution in eight dimensions.
