I love listening to physics talks and seminars, but hate the whole experience of going to the department and being crammed into a room with other researchers. Also, how many times have you lost concentration for 30 seconds whilst listening to a talk, only to tune back in to find that you've missed a vital piece of information or step in the reasoning, which makes the rest of the talk impossible to follow? Wouldn't it be great to be able to pause or rewind the speaker?
There are a few institutions who helpfully publish their seminar series online:
- The Isaac Newton Institute for Mathematical Sciences in Cambridge
- The Kavli Institute for Theoretical Physics in California (see their Public Lectures for fascinating introductory talks aimed at the general public)
- Rutgers Physics Department
- MIT also have lecture notes and videos available for a wide variety of physics courses, helpful for anyone wishing to self-study.
This is not a comprehensive list of institutions, rather a list of those that I found which have significant amounts of up-to-date and interesting material. I will be updating the list as I find more sources.
