Modern Physics Glowing in the Dark: Marie Curie and the Atom That Wouldn't Sit Still
Stable lead-208 nucleus beside an unstable radium-226 nucleus that decays into radon-222, releasing an alpha particle and energy; heating, cooling, dissolving, or sealing the sample does not change the decay rate
A mysterious mineral that glows brighter than the uranium it should have come from — the puzzle that led Marie Curie into the nucleus of the atom itself, and into a discovery that would go on to power cancer treatment, WWI battlefield X-ray units, and the science of nuclear decay.

Modern Physics The Light in the Dark: Einstein, the Photoelectric Effect, and the Battle for Reality A struggling patent clerk, a stubborn experimental result wave theory couldn't explain, and a wild idea — that light itself arrives in discrete energetic packets, not a smooth continuous wave. The photoelectric effect that a young Albert Einstein used to upend a century of physics, and that now powers everything from solar panels to digital cameras. Open Reading Passage
