Physics
The study of how the world works at a fundamental level.
Theory of space and time, either not or in the influence of gravity.
How and why things move the way they do.
Electromagnetism, the Weak interaction and the Strong interaction & gravity
Study of fundamental particles and interactions that make up matter & radiation -- up to nucleons.
On nuclear matter (prominently atomic nuclei); its interactions and what makes up the stuff.
Ahh, thermodynamics.
Certain behaviors & phenomena of nature which appear noticeably at atomic and subatomic scales.
Fringe theories. Paraphysics (e.g. psionics): literary overview, advice, possible justifications.

Summary: The picture on the left is a laser-generated Target Normal Sheath Acceleration proton source. A relativistically intense laser hits a foil and blows out a huge jet of protons (and electrons) at MeV energies.
