Great lecture, just like to correct a small error. As a Scot myself, I'd like to claim William Thompson for Scotland, and indeed he spent his very long career at Glasgow University. But he was born in Northern Ireland, and lived there until he was about 10 years old. I've been to Belfast, and there is a statue of him in the precincts of Queens University. So - "Scottish born" is not a correct description. His enobled title - Kelvin - comes from a small tributary of the River Clyde which flows through the grounds of Glasgow University, which does indicate that he embraced fully his adopted land. I like to explain to my students the process by which a pretty but otherwise unimpressive Scottish stream helped to name one of the base SI units...
Great presentation... with much interesting historical context. Thanks!!
I learned a lot. Thank you very much for this video.

They don't teach in modern day electromagnetism textbooks that Faraday and Maxwell interpreted field as strains on the aether . Nice job by prof Kaiser throwing light on these facts
Really enjoy this course, David Kaiser is incredible online lecturer , captivating...I am sure he has many super powers, one of them is explaining very difficult topics
46:29 gravity poisson equation has wrong signs
Some awesome historical context in here.

Scientific institutions independent of universities still exist and do eminent work. (For example, national and world institutes of medicine, pharmaceutical companies, NASA, IAS and the like.) Also, I believe the university system as a whole has done a laudable job taking up the mantle of research and scientific investigation. However, in my opinion, the control that universities have over science has become too strict. The web of universities has a -- let's say, nearly -- monopolistic grip on the process and authority of science (just has it a oversize grip on post-secondary education -- but that's a separate, if related, matter). It seems plausible to me that if societies encouraged other organizations, besides universities, to take on science, there might be interesting and beneficial outcomes. Sometimes, outsider thinking sees connections that bright but otherwise conventional-ish minds cannot.
