Once I stayed in an Airbnb owned by Karl Friederich Gauss' distant relatives in Brazil. It was a very cozy cabin in the mountains around Rio and I was celebrating a two-year anniversary with my girlfriend. There were a few books arranged in a short rack, mostly teen stuff, but one aged book stood out. It was an English version of Gauss' Theory of the Motion of the Heavenly Bodies, apparently borrowed from an university library in the 1970s but never returned. Inside, I found two documents from 1969, a voter registration and an exam card. They belonged to a woman with a Brazilian first name and Gauss' surname. Later, I had to transfer money to the Airbnb host, and she also had Gauss as a surname. I was pretty thrilled with the whole thing. My girlfriend was more entertained by the cabin's cat.
