Other notable sites:
Loads of computer science, also heavy on physics and math but no original content…
Reddit has a lot of subbreddits, one of my favourites is the “Lectures”, 5000+ readers and new lectures posted regularily on pretty much any topic you can think of, the subreddit is moderated by “pkrumins” the same Krumins from the site mentioned above.
Loads of short concise explanation on math topics sets this page out from the rest.
