Physics

Natural Sciences

The deepest layer of natural law — matter, energy, space, and time, and the symmetries that govern them.

Notes

Electromagnetism

Electric and magnetic fields, charges, currents, induction, and electromagnetic waves

Fluid Mechanics

Pressure, density, viscosity, flow regimes, Bernoulli's principle, and the Navier-Stokes equations governing fluid motion

General Relativity

Spacetime curvature as the origin of gravity; geodesics, black holes, gravitational waves, and the large-scale structure of the universe.

Newtonian Mechanics

Classical mechanics of particles and rigid bodies: forces, motion, energy, momentum, frames, and the deterministic laws governing macroscopic dynamics.

Optics

Light as rays and waves: reflection, refraction, interference, diffraction, polarization, and the design of optical instruments and systems

Quantum Mechanics

Wave functions, superposition, uncertainty, quantization, and the probabilistic description of particles and fields at the smallest scales

Thermodynamics

Heat, energy, entropy, work, and the fundamental limits on transformations of matter and energy

Wave Mechanics

Oscillations, traveling and standing waves, superposition, resonance, Fourier analysis, and the wave equation across mechanical, acoustic, electromagnetic, and quantum domains
