## A few lectures

(This was a review lecture for me as I read a textbook on these topics a few months back going into quite a lot more detail – the post I link to has some relevant links if you’re curious to explore this topic further).

…

A few relevant links: Group (featured), symmetry group, Cayley table, Abelian group, Symmetry groups of Platonic solids, dual polyhedron, Lagrange’s theorem (group theory), Fermat’s little theorem. I think he was perhaps trying to cover a little bit too much ground in too little time by bringing up the RSA algorithm towards the end, but I’m sort of surprised how many people disliked the video; I don’t think it’s that bad.

…

The beginning of the lecture has a lot of remarks about Fourier‘s life which are in some sense not ‘directly related’ to the mathematics, and so if this is what you’re most interested in knowing more about you can probably skip the first 11 minutes or so of the lecture without missing out on much. The lecture is very non-technical compared to coverage like this, this, and this (…or this).

…

I think one thing worth mentioning here is that the lecturer is the author of a rather amazing book on the topic he talks about in the lecture.
