The May talk will be given by Prof Gregory Sankaran who will be talking about an interesting pure mathematics problem.

*What is the most efficient way to pack small spherical objects into a large space? This problem makes sense for spheres of any dimension. It was solved in dimension 2 by bees and in dimension 3 by greengrocers, although the proof in the latter case is very complicated.*

*Recently the problem was solved in dimensions 8 and 24 by the Ukrainian mathematician Maryna Viazovska. In this talk Prof Sankaran will describe the background to this and say a little about how she did it.*

Prof Sankaran is a Professor of Pure Mathematics at the University of Bath. His research is in algebraic geometry, occasionally bordering on number theory or computer science.
