Lately I have been teaching myself higher level physics and mathematics – reading books and watching Youtube videos on the subject. Here I am going to post some links to the resources I have been using for anyone else who may be interested. These resources are obviously not exhaustive of all the resources out there, but they’re the ones I’ve found to be very helpful. As I continue learning about these subjects, I will periodically update this post.

## Youtube

PBS Spacetime: a great resource for physics that stands between pop science and more rigorous (i.e. mathematical) treatments of the subject. They cover pop science subjects (black holes, quantum mechanics, cosmology, string theory, etc.) but go deeper into the concepts, often even brushing up against the complicated mathematics. They use a lot of great animations to help explain the subjects.

DrPhysicsA: a British guy who never shows his face (and hasn’t added a new video in several years) but goes through the mathematics of a wide range of physics at a level that’s easy to understand. A great place for the person who graduates from the PBS Spacetime level and wants to actually get a basic grasp of the mathematics involved. DrPhysicsA does a great job of meticulously going through every mathematical detail, not leaving anything for the viewer to get confused about between steps.

3blue1brown: a great resource for getting an intuitive understanding of math. He does a lot of videos on sort of “pop math” type stuff, but he also has playlists on the “essence of calculus” and the “essence of linear algebra” which are extremely helpful to people who want a visual and intuitive understanding of these topics. His “pop math” videos are great, too, and very well put together.

Andrew Dotson: a physics graduate student who makes videos about physics and math. He does a lot of vlogs, skits, meme reviews etc., but he also does videos about physics itself – especially check out his “derivation” playlist and his “new to tensors?” playlist.

TMP Chem: these videos are more chemistry related, but he touches on a lot of physics topics as well – things like statistical mechanics, physical chemistry, and so on. Most videos are fairly short (under 10 minutes) and he does a good job of explaining things.

XylyXylyX: a great resource for very high level math and physics (particularly his 70+ video playlist explaining general relativity). He does a great job of being extremely thorough, repeating important points often to ensure you know what to remember, and starting everything from very basic principles. He has playlists on topics that are difficult to find good resources for, including topology, Lie groups, tensors, and the aforementioned behemoth of a playlist on general relativity.

The Cynical Philosopher: of course I cannot go without mentioning my own Youtube channel. I have a playlist I am making about Quantum Mechanics and I have a playlist on the special functions encountered in differential equations (Hermite polynomials, Bessel functions, Legendre and associated Legendre polynomials, etc.).
