The Flyspeck project is complete: we know how to stack balls!
A team led by Thomas Hales has announced a formal proof of the Kepler conjecture – one of the oldest problems in geometry – which states that no packing of equally sized spheres in 3-dimensional space is more efficient than the face-centred cubic packing (pictured right), or hexagonal close packing.
Interesting Esoterica Summation, volume 9
Oof! It’s been nearly a year since I last shared my findings in the field of interesting esoterica. I fear this may be quite a long post. In case you’re new to this: every now and then I encounter a paper or a book or an article that grabs my interest but isn’t directly useful for anything.…
Small gaps between large gaps between primes results
The big news last year was the quest to find a lower bound for the gap between pairs of large primes, started by Yitang Zhang and carried on chiefly by Terry Tao and the fresh-faced James Maynard. Now that progress on the twin prime conjecture has slowed down, they’ve both turned their attentions toward the opposite question:…

We’re Stuck! is an Arts Council funded piece of interactive theatre aimed at children aged 7-12 and their families. The project will explore the idea that getting stuck is part of doing maths, and not something to be feared. The aim is to promote…
