Antoine Henri Becquerel discovered radioactivity completely by accident when he exposed a chunk of uranium to a photographic plate. This opened up a whole new field of research to uncover the source of the mysterious energy.

Ep. 372: The Millikan Oil Drop
In 1909 Robert Millikan devised an ingenious experiment to figure out the charge of an electron using a drop of oil. Let’s talk about this Nobel Prize winning experiment.
Ep. 371: Eddington Eclipse Experiment
At the turn of the 20th Century, Einstein’s theory of relativity stunned the physics world, but the experimental evidence needed to be found. And so, in 1919, another respected astronomer, Arthur Eddington, observed the deflection of stars by the gravity of the Sun during a solar eclipse. Here’s the story of that famous experiment.
Ep. 370: The Kaufmann–Bucherer–Neumann Experiments
One of the most amazing implications of Einstein’s relativity is the fact that the inertial mass of an object depends on its velocity. That sounds like a difficult thing to test, but that’s exactly what happened through a series of experiments performed by Kaufmann, Bucherer, Neumann and others.
