The statistician Stephen Stigler once wrote an elegant essay about the futility of the practice of eponymy in science—that is, the practice of naming a scientific discovery after its inventor. That's another idea inappropriately borrowed from the cultural realm. As Stigler pointed out, "It can be found that Laplace employed Fourier Transforms in print before Fourier published on the topic, that Lagrange presented Laplace Transforms before Laplace began his scientific career, that Poisson published the Cauchy distribution in 1824, twenty-nine years before Cauchy touched on it in an incidental manner, and that Bienaymé stated and proved the Chebychev Inequality a decade before and in greater generality than Chebychev's first work on the topic." For that matter, the Pythagorean theorem was known before Pythagoras; Gaussian distributions were not discovered by Gauss. The examples were so legion that Stigler declared the existence of Stigler's Law: "No scientific discovery is named after its original discoverer." There are just too many people with an equal shot at those ideas floating out there in the ether. We think we're pinning medals on heroes. In fact, we're pinning tails on donkeys.
