James Rigby will perplex us with Mr Reimann, his famous hypothesis, and why it's important. I looked it up on Wikipedia and I’m none the wiser, but it’s something to do with Number Theory and is considered by many to be the most important unsolved problem in pure maths. So pay attention.

As usual we will be attempting to livestream the talk (very much at the mercy of the pub’s wifi connection). The link to watch that is https://youtu.be/_kLo1XKPVNQ.
