I'm an unemployed guy who knows a bit of physics. I've been participating in the Wikipedia since December 10, 2001, writing articles that mostly fall under classical mechanics, condensed matter physics, and quantum mechanics. These are the articles that I have written a substantial part of, and take an active interest in:

Physics: Black hole Bra-ket notation Chemical potential Classical mechanics Correspondence principle Dirac equation Electric field screening Entropy EPR paradox Feynman diagram Grovers algorithm Hamiltonian Hamiltonian mechanics Identical particles Lagrangian Mass No cloning theorem Paul Dirac Pauli exclusion principle Pauli matrices Phase (matter) Phase transition Phonon Physics Quantum entanglement Quantum field theory Quantum Hall effect Quantum harmonic oscillator Quantum mechanics Schrodingers cat Spin (physics) Standard Model Superconductivity Wolfgang Ernst Pauli
