PI has quite a lot at YT, as can be seen by visiting YT and searching on “Perimeter Institute”, but I could not find these lectures.

These are top-secret lectures for experts only.

Just kidding! How many of the Perimeter Institute Recorded Seminar Archive lectures are on YouTube, anyway?

I don’t really care if these lectures of mine are on YouTube except that it might slightly increase the chance of their being preserved for a long time. I downloaded copies for that reason.

]]>• Can we understand the Standard Model using octonions?

I now give a rough explanation of why the subgroups

show up in this game, and why their intersection is the true gauge group of the Standard Model.

]]>It depends a lot on what you mean by “the idea”. Cohl Furey and Mia Hughes have some ideas involving the Standard Model and octonions, Kirill Krasnov has some others, Latham Boyle has some others and Dubois-Violette and Todorov have some others!

My talks only describe some mathematical facts connecting octonions and the Standard Model—I’m not proposing a theory. The most exciting of these facts was first discovered by Dubois-Violette and Todorov, and my second talk explains it.
