What does this prove? Some of the most gorgeous visual "shrink" proofs ever invented
Bit of a mystery Mathologer today with the title of the video not giving away much. Anyway it all starts with the quest for equilateral triangles in square grids and by the end of it we find ourselves once more in the realms of irrationality. This video contains some extra gorgeous visual

Andreas Bernig: Intrinsic volumes on pseudo-Riemannian manifolds
The intrinsic volumes in Euclidean space can be defined via Steiner’s tube formula and were characterized by Hadwiger as the unique continuous, translation and rotation invariant valuations. By the Weyl principle, their extension to Riemannian manifolds behaves naturally under isometric em

All kinds of big: Hadwiger's Theorem
A survey talk about Hadwiger's theorem, which describes all possible "measures of bigness" for sets in space. Meant for a general quantitatively literate audience- hopefully understandable to anybody who can handle basic mathematical ideas. I gave this talk at the weekly colloquium for the

Aubrey de Grey on his Mathematics Research and Longevity | Hadwiger- Nelson Problem.
I got lucky to have Dr. de Grey talk to me about his mathematics research and his academic life in general. In 2018, he proved that the chromatic number of a plane should be at least 5. The original paper can be found here: https://arxiv.org/abs/1804.02385 You can contact Aubrey via thi
