The amazing coincidences in this episode of The List Show are drawn from the worlds of astronomy, politics, literature, and more. We've got well-known historical coincidences like the day John Adams and Thomas Jefferson passed away, along with some lesser-known (or less-considered) coincidences. You'll learn why dinosaurs didn't enjoy total solar eclipses and find out that Galileo had an idiosyncratic (and let's just say it, kind of annoying) way of communicating with his science buddies.
