Very good video. It was hard for me to find a physics video without being too basic, your video is therefore excellent!

Brilliant video! I'm still learning non-relativistic quantum mechanics and have only a little exposure to QFT, but I was able to understand pretty well. Great job!

Hi, great video! Could you suggest some texts that provide a pedagogical review of this topic? Many thanks.

If the mass is a function of such a particle interacting with the Higgs field could such a large mass be explain by a higher frequency interaction than expected? In other words it might not be more massive but instead have higher energy with respect to the Higgs field.

You should also discuss how we know that theta doesn't equal pi, which is the other CP invariant value. This is a famous paper by Witten which uses the chiral perturbation theory of pions.

Why doesn't a similar problem arise in the case of QED then, where the Lagrangian has the same structure as the one for QCD? Why is the CP-violating term not considered/noncontributing there?

Would love to see you do a video on photon propagator derivation using path integrals. Need not be in a single video. May be do a video on Fadeev popov method.

Could you also try to do a video on projective representations of Lorentz group. BTW, great work!
