Electromagnetism & Waves
2-3 weeksStudy Maxwell's equations, electromagnetic waves, optics, and the classical field concept. Understand how the unification of electricity and magnetism set the stage for modern physics.
Special Relativity
2-3 weeksLearn Lorentz transformations, time dilation, length contraction, relativistic momentum and energy, E=mc^2, and four-vector formalism. Understand spacetime diagrams.
Quantum Mechanics
4-6 weeksStudy the Schrodinger equation, wave functions, operators, eigenvalues, the uncertainty principle, angular momentum, spin, and the hydrogen atom. Understand measurement and superposition.
Statistical Mechanics & Thermodynamics
2-3 weeksExplore the statistical foundations of thermodynamics: ensembles, partition functions, entropy, phase transitions, and the connection between microscopic and macroscopic physics.
General Relativity & Cosmology
4-6 weeksLearn tensor calculus, curved spacetime, the Einstein field equations, black holes, gravitational waves, and the Friedmann equations governing the expanding universe.
Quantum Field Theory & the Standard Model
6-8 weeksStudy canonical quantization, path integrals, Feynman diagrams, renormalization, gauge theories, quantum electrodynamics, quantum chromodynamics, and the electroweak theory.
Advanced Topics & Frontiers
4-8 weeksExplore string theory, loop quantum gravity, supersymmetry, black hole information paradox, quantum entanglement foundations, dark matter and dark energy models, and current open problems.
