I'm a phyiscs student and I have been looking at these lectures: https://www.youtube.com/playlist?list=PL6763F57A61FE6FE8 But I have never learned anything about topology before and was he covers doesn't look like the Topology chapter in my mathematical physics book. I was looking for something maybe for undergrad math majors that goes a little more slowly than my book. This seems to be the pace I want but, while interesting, doesn't seem to be the same topic. The book starts with what is an open set, neighborhoods, ect but the videos are just talking about shapes. He said this stuff is relevant to physics, but I'm wondering if I'm missing the fundamental stuff? I've just finished studying algebra (in the modern sense).
