Category Theory III 2.1: String Diagrams part 1

[@TmooreSweden]

Thanks for putting these up online they're thoroughly enjoyable to watch! There are a constant humming going on in the background of the noice that should be easily avoidable using some easily abtainable audio program. Some audio devices increases that tiny irritating sound to a level that makes it a bit hard to concentrate on what you're teaching.
