For those interested, there is a more precise introductory description of renormalization (ie what I mean by ‘relationships amongst observables’ and their ‘parameterization using couplings’) in sec 17.2 of these notes physics.mcmaster.ca/~cburgess/Note…

I just learned that Fred Goldhaber passed away this afternoon. Fred made a remarkable discovery 50 years ago; If you add a boson of electric charge 1 on top of a boson magnetic monopole of charge 1, you get a fermion composite particle.

The entire field of theoretical physics is not about bullying people to get credit. It is about solving problems and gaining appreciation from the community.
