on this stuff?

Other curious puzzles
Why is the weak scale stable vs. quantum
corrections?
Why is there more matter than antimatter?
Are neutrinos trying to tell us something?
How can other fields tell us about our
theory of matter and forces?

Particle Phenomenology
MYSTERY
examples:
Theory: what makes W scattering unitary? (Higgs boson)
Experiment: observed excess in 𝛾-rays … dark matter?

Advice
Find material appropriate to your level and interests, and
read aggressively: lectures, review articles.
Better: keep a notebook and do calculations. Write them
pedagogically, and let yourself be wrong. Aim to be
wrong in every reasonable way and annotate the pitfalls.
