Quantum & Modern Physics
The 20th-century revolutions in physics — and the phenomena that still don't make sense.
Modern physics is the catch-all term for everything physics discovered after about 1900 — when the comfortable Newtonian universe started failing in two directions at once. At very small scales it gave way to quantum mechanics. At very high speeds and large gravitational fields it gave way to relativity. The cluster of articles below covers both, plus the strange phenomena that emerge from them.

Quantum Mechanics Made Simple
The wave-particle duality, Schrödinger's cat, superposition, entanglement — the core ideas of quantum mechanics in plain English.
Top 10 Mind-Boggling Physics Phenomena
Entanglement, black hole singularities, time dilation, dark matter, the Higgs boson, quantum tunneling, the arrow of time — ten phenomena that defy ordinary intuition.
The Science Behind Space Exploration
Rocket propulsion, orbital mechanics, gravitational slingshots, GPS-and-relativity, and the engineering physics of leaving Earth.
