Crash Course Physics is set up to be supplemental if you're taking a class in the topic, or to give you an introduction if you're just naturally curious. They tend to go fast, but the beauty of putting these on YouTube is you can back up and watch it again and again to make sure you're grokking everything going on.

Crash Course Physics - Lev Landau - Netflix
Lev Davidovich Landau (22 January 1908 - April 1968) was a Soviet physicist who made fundamental contributions to many areas of theoretical physics. His accomplishments include the independent co-discovery of the density matrix method in quantum mechanics (alongside John von Neumann), the quantum mechanical theory of diamagnetism, the theory of superfluidity, the theory of second-order phase transitions, the Ginzburg–Landau theory of superconductivity, the theory of Fermi liquid, the explanation of Landau damping in plasma physics, the Landau pole in quantum electrodynamics, the two-component theory of neutrinos, and Landau's equations for S matrix singularities. He received the 1962 Nobel Prize in Physics for his development of a mathematical theory of superfluidity that accounts for the properties of liquid helium II at a temperature below 2.17 K (−270.98 °C).
