A lot of my favorite physics classes were Applied Physics. These were great as you used the building blocks from 1st/2nd year level to show complex phenomena in the universe. It is a shame this list has none of these.<p>Things like:<p>* Stellar Nucleosynthesis - S-process, R-process, stellar evolution<p>* Fluid mechanics - Navier Stokes equations<p>* Physical Oceanogrpahy - Ocean currents, tides, Pressure and Salinity effects<p>* Plasma Physics - MHD equations, Alfven waves<p>* Medical Physics - CAT, PET, MRI scanners. Radiation treatments.<p>* Planetary Science - Plate tectonics, Gas giant phenomena.<p>* Geophysics - EM, seismic, anisotropy<p>* Electron Microscopy - SEM, TEM, AFM etc.
