A series of videos explaining quantum mechanics, using math but with more emphasis on intuition than you will find in most textbooks. If you think you’re an idiot when it comes to learning these tough subjects, you might benefit by learning from me, a fellow idiot.

The number of videos I’ve made on this subject is getting too long to post them all here individually, so here are my playlists on quantum mechanics.

The above is the full quantum mechanics playlist, containing everything quantum, including spin/polarization, solutions to the Schrödinger equation, approximation techniques, scattering, and more.

The above playlist covers everything related to light polarization and particle spin from an undergraduate level. This includes Pauli matrices, angular momentum, EPR paradox and Bell’s inequality, Larmor precession, Stern-Gerlach experiment, the Aharonov-Bohm effect, and more.

This playlist covers solutions to the Schrödinger equation, including infinite rectangular well, finite rectangular well, and harmonic oscillator in 1D, and the spherical potential and hydrogen atom in 3D (spherical harmonics and radial equation). If you are not familiar with special functions in differential equations, I highly recommend you check out the next playlist before tackling this one.

This playlist is much more mathematical, without a focus on physics, but the topics are vital for understanding the solutions to the Schrödinger equation. Topics covered in the Differential Equations playlist are orthogonal polynomials, Legendre and associated Legendre functions, Spherical harmonics, Bessel and Spherical functions, Laguerre and associated Laguerre polynomials, Hermite polynomials, and the Frobenius method. The videos that come after this point all assume you understand these concepts.

This playlist covers approximation methods, such as perturbation theory, variational methods, and the WKB approximation.

While the other playlists so far have focused on the so-called “shut up and calculate” approach to quantum mechanics, this playlist examines the philosophy and interpretation of quantum mechanics, including the locality problem, the ontology problem, the measurement problem, the Copenhagen interpretation, pilot-wave theory (aka Bohmian mechanics), EPR paradox and Bell’s theorem, objective collapse theories, and the many-worlds interpretation.
