The Stern-Gerlach Experiment – A history of stubbornness
Even scientists are only human. That’s why success stories often read like a comic book: great heroes fighting for the good of humanity. From another perspective, however, it sometimes seems more like the nagging of old white men arguing over who is right. We have already seen a few examples of this: Boltzmann and Planck fighting over entropy, Thomson and Rutherford decoding the atom, Newton and the rest of the world racking their brains over the nature of light. And the Stern-Gerlach experiment, which celebrated its hundredth anniversary this month and which is a milestone of quantum physics, was ultimately the invention of a scientist who desperately wanted to be right.
