Series
- The Biggest Ideas in the Universe by Sean Carroll covers a lot of physics, and each has a Q&A video. It's not teaching material in the sense that you could go and apply this stuff, but you'll learn concepts and see how it all fits together. Highly recommended.
- The Theoretical Minimum is a collection of courses by Leonard Susskind aimed at getting continued learning students going as quickly as possible, while teaching real physics. These are actual classroom
blackboardwhiteboard lectures, not that tone-deaf MOOC junk where someone tries to educate a camera.The math is taught as-needed. Technically there are some prerequisites, but everything is explained well enough that you can follow along and understand the mathematical meaning of everything that's being taught.
If you are not interested in doing the classical mechanics course first, you could start on the QM course. Most of the classical stuff that's involved will be mentioned explicitly, so you will know what's going on, it just won't get the full treatment.
(In case you are binging the stuff, you might want to check Stanford's channel for a playlist for that lecture series. For example: Quantum Mechanics.)
Finally, there are a couple of books for this series. The site links them in the References section. In a pinch, you can find them on archive.org. (I debated whether to mention this or not. In the end: do what thou wilt.)
- NoahExplainsPhysics has a few series explaining physics, including QM concepts. These are structured around the math in a way that makes the math clear and make the connection to the concepts being taught clear as well.
Due to the way these are presented, they're useful for clearing up any issues about the math. How to do it, how to apply it, what it means — all of that is clear from the examples and explanations he gives.
The first two are classical mechanics. The Quantum Spin series actually covers quite a lot of QM. Spin is connected to a lot of things, and he goes deep.
I can't recommend these enough. (If don't want to do a whole playlist, he does have a one-off that I recommend below.)

Noether's Theorem Explained
Quantum Spin
Reference
- Classroom Instructional Vibes
Physics Videos By Eugene Khutoryansky is a channel I encourage you to use as a reference. Lots of topics in physics explained very well, in an idiosyncratic style you may find familiar. - The Metaphysical Space
David Z. Albert gives a talk on How to Teach Quantum Mechanics. Philosophy professor talks about how to frame QM in a way that makes certain things clear. Not for everyone, but he has an interesting point and makes it well. - Uncertainty
The more general uncertainty principle, beyond quantum by 3Blue1Brown explains that uncertainty (quantum or otherwise) is an everyday thing you can understand given some reasonable assumptions.PBS Space Time does a pretty good job on this topic too, in Understanding the Uncertainty Principle with Quantum Fourier Series.
- Fourier Transform
But what is the Fourier Transform? A visual introduction by 3Blue1Brown is the best introduction to the Fourier transform I've found. Worth spending some time on, since QM couldn't exist without this, yet it's rarely talked about. - Quantum Spin, Symmetry Groups
In Dirac's belt trick, Topology, and Spin ½ particles, NoahExplainsPhysics demystifies electron spin, and gives probably the best explanation of symmetry groups you will ever get. - Quantum Information (The Holographic Principle, AdS/CFT)
In Quantum information and spacetime (part 2), John Preskill explains quantum information. In particular, this has a great explanation of the holographic principle.While this is relevant to quantum computing, it applies more generally and teaches about concepts that are used in other contexts. Especially recommended if you are going to learn about string theory.
Quantum Computing
- Patrick Hayden explains the basics of quantum computation in The Quantum Computational Universe (part 2. No prior knowledge is assumed.
- Quantum Computational Supremacy explained by Scott Aaronson. He talks about what Google's demonstration did and how to interpret it.
- John Preskill's Ph/CS 219A Quantum Computation class. I had high hopes for this because Preskill is really good. But there are problems.
First, this wasn't recorded because Preskill is good at lecturing this way, it was recorded out of necessity because world events turned his class into a remote learning class. He's alone, talking to a camera, teaching from slides and occasionally having computer problems.
Second, this is a bit abrupt. You'll need to understand the math and he won't be explaining very much of it. Noah's series can help with this, but you might still be missing a few things.
However, it is a good course. Probably the best on the subject. If you're looking to learn this in detail, this is the course for it and it's freely available online.
Edutainment
This stuff is lighter than the rest. The vast majority of things in this category would be excluded outright, but these have enough merit that I couldn't rightly leave them out.
- Sabine Hossenfelder tends to talk about things nobody else does. She's also known for being outspoken about her criticisms of programs and ideas in physics and science in general, but she's not controversial for the sake of it.
- PBS Space Time covers many topics, sometimes with surprising depth for this kind of channel. This could almost have been listed as reference material, but the videos tend to bring up more than they explain.
