# Theoretical Minimum Lectures by Leonard Susskind

For those looking for good free physics courses online, my best recommendation is Leonard Susskind’s lectures. Susskind’s lectures on a variety of physics topics can be found on YouTube as a part of Stanford University’s open lectures. Besides being a renowned theoretical physicists, Susskind is also known for his easy-to-follow lectures. The problem, ironically, is that there are so many lectures, it’s hard to find what you looking for. Fortunately, there is a great website, which offers all the most important lectures in different formats.

The Theoretical Minimum website includes 6 main lecture courses, plus additional 9 courses on advanced topics. The archive section contains older versions of the core courses. Here’s the list of topics covered in core courses:

1.** Classical Mechanics** (Newton’s laws, Lagrangian, electromagnetic fields, symmetries and conversations)

2. **Quantum Mechanics** (vector spaces, Schrodinger’s equation, entanglement, Fourier analysis, particles)

3. **Special Relativity and Electrodynamics **(Lorentz transformations, velocity addition, classical field theory, Maxwell equations)

4. **General Relativity** (equivalence principle, tensors, curvature, geodesics, black holes, field equations, gravity waves)

5. **Cosmology** (expanding universe, curvature, cosmic thermodynamics, baryogenesis, inflation, quantum fluctuations)

6. **Statistical physics** (entropy, temperature, Boltzmann distribution, reversibility, liquid-gas transition)
