We just got back from a long weekend trip to the beach, in Montezuma, on the southern curve of Costa Rica’s Nicoya peninsula. The thing with peninsulas is that they are surrounded by coastline, and the thing with coastline is that has lots of beaches:
We arrived at our hotel, El Tajalin (native word for a local land crab).
Amazing right? But think about the chances of this happening. Clearly currents were such that the goggles never left that section of the beach. But that section covered and area of roughly 2 full acres (~8000 m^2). The goggles take up about 100 cm^2, so if the probability of them being in any one spot was equal (which is surely wasn’t) the chance of stepping IN THEM as I did was something 0.000125%. Of course, the location was probably determined by random walk process, which means the probability of the goggles being in the same place was the greatest of all places, albeit quite small. I will leave that calculation as an exercise to the reader.
