Last semester I was a GTA for First Year Computing Labs. Relevant blog posts are tagged as #PHY113.
This term I’m teaching Core Physics II, which covers Thermodynamics & Stat. Mech., QM II, Solids II, Nuclear Physics and Atomic Physics.
You can also check out a lecture on spontaneous symmetry breaking and the Higgs mechanism I gave as part of the graduate (PhD) lectures on particle physics in Sheffield, and one on decays and crosssections I gave to fourth year students (some extra material is tagged #PHY421.
