The laser grew from quantum theory, masers, optical engineering, and patent battles. This article explains how coherent light became a world-changing tool.

Hertz spotted it in 1887. Lenard mapped its rules. Einstein explained it in 1905. Millikan spent a decade trying to disprove Einstein — and ended up confirming him.

Max Planck's 1900 quantum hypothesis solved the blackbody radiation puzzle and launched quantum physics. Learn his science, tragedies, and lasting legacy.

Richard Feynman's biography, quantum electrodynamics, and verified quirks: safecracking at the bomb lab, bongo drums in strip clubs, learning Portuguese on a whim.

Wave-particle duality, uncertainty, superposition, entanglement — what quantum physics actually says, what it predicts, and what it doesn't.

For every particle of matter, physics predicts a mirror twin made of antimatter. We make it, store it, and use it in medicine — but we still don't know why the universe has so little of it.

The simulation hypothesis isn't just sci-fi — physicists, philosophers, and tech billionaires have argued it's mathematically plausible. Here's what the actual science says.

"Quantum," "subatomic," and "atomic" sound similar and get used interchangeably — but they describe different scales and concepts. Here's a clear explanation that untangles them.
