Each gate is a self-contained area with its own language, its own intuitions, and its own famous problems. Start anywhere — they all eventually connect.
Newton to Hamilton
Motion, forces, energy, and the elegant reformulations of Lagrange and Hamilton that underpin all of modern physics.
Light as a wave
Geometric and wave optics: reflection, refraction, interference, diffraction, polarization, and the design of optical instruments.
Maxwell's unification
From Coulomb's law to Maxwell's equations and electromagnetic waves — the theory that gave us light, radio, and relativity.
Heat, entropy, ensembles
Laws of thermodynamics and the statistical foundations that connect microscopic dynamics to macroscopic behavior.
Waves, operators, probability
The strange, beautiful theory of the very small: superposition, entanglement, measurement, and the Schrödinger equation.
Inside the atom
Structure of the nucleus, radioactive decay, nuclear reactions, fission and fusion — and how stars forge the elements.
The Standard Model
Quarks, leptons, gauge bosons and the Higgs — plus the open questions that point beyond the Standard Model.
