https://peertube.wtf/videos/watch/c39062cf-0156-4188-a4d6-158c35aae325 This is the second in a series of talks about universal algebra and lattice theory. I give examples of algebras, including magmas, semigroups, monoids, groups, rings, modules, semilattices, lattices, quasigroups, Latin squares, and n-ary magmas. The webpage for this series of talks can be found at https://aten.cool/2020ua.html. (Typo near the end: I acutally gave an example of an (n-1)-ary magma, so I was off by one.)
