https://peertube.wtf/videos/watch/1456f5d5-4e08-4772-93c4-fa21b15cb67b This is the sixth in a series of talks about universal algebra and lattice theory. I introduce the distributive and modular laws and describe their relationship to each other and to duality in lattices. I proceed to present Dedekind and Birkhoff's results characterizing these two laws and end with a little note about graph theory.
