Originally shared by Jennifer OuelletteHow do you determine the direction a bicycle went when you come upon just its tracks? The question goes back to the early days of the bicycle age and a 1903 Sherlock Holmes story by Sir Arthur Conan Doyle called “The Adventure of the Priory School.” Surprisingly, Holmes's reasoning in the story was incorrect. http://www.simonsfoundation.org/multimedia/mathematical-impressions-bicycle-tracks/
