Modern Physics Path
Classical physics breaks down at very high speeds and very small scales. This path walks you through what replaced it: special relativity, quantum ideas, atomic structure, and nuclear physics — each built on the last, with the math kept honest but approachable.
Module 1: Special relativity
Why simultaneity is relative, and how moving clocks run slow.

Module 2: Energy, mass, and duality
E = mc² and the double life of light and matter as waves and particles.

Module 3: The quantum revolution
The experiments that forced quantum theory: photons knocking out electrons, and the Bohr atom.

Module 4: Uncertainty
What the uncertainty principle really says — and the myths it does not support.

Module 5: Nuclear physics
Alpha, beta and gamma decay, half-life calculations, and fission vs fusion.
