I mostly self learn Physics, I don't have a degree.

I have a good grasp on:

• physics we learned at high school.
• A-level physics topics.
• Special relativity.
• Maxwell equations.

Topics I get the idea but still struggle with the mathematics:

• General relativity. (have a good grasp on the Riemann curvature tensor, but yet to get a good intuitive grasp the Ricci tensor and stress-energy tensor).
• Quantum mechanics. (I tend to stick to wave-functions with or without asterisk and operators, the asymmetric braket notation still look too alien to me.)

Topic I barely scratched the surface on:

• Quantum field theory. (I think I got the idea of the Fock space and the annihilation and creation operators, but still need a lot of work understand how and why it works.)
