The Strange Origins of Eponymous Laws
Many famous laws are named after people who never actually proposed them. While some scientists like Newton formulated their own rules, other famous adages were coined by outsiders as jokes or observations about human behavior.
We often assume a law carries the name of its creator, but that is rarely the whole story. Murphy's Law, for instance, was named after an engineer who had nothing to do with the original quote's popularity. Some laws are named in jest to describe recurring frustrations, while others honor pioneers who only inspired the observation. These labels tell us more about our human tendency to categorize brilliance than the actual history of discovery.
