Here at Anecdote, we’re gearing up to turn 15 years old! We’ve been taking a trip down memory lane as we prepare for our big day. Keep an eye on our Instagram page, @RealAnecdote, for some flashbacks!

In this episode, Mark retells the story contained in Dava Sobel’s Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time. As the title suggests, the story follows John Harrison and his attempts to solve the greatest scientific problem of his time - calculating longitude. It dates back to the 1700s.
