Imprisoned for heresy, Gerardus Mercator later created a map that transformed navigation forever. We explore why his projection distorts the world, how it solved a deadly problem for sailors, and the astonishing mystery of how he used math that hadn’t even been invented yet to do it all.
Be Smart explores science questions you didn’t even know you wondered about. It is hosted and produced by Joe Hanson, PhD. We post new videos all the time, so please subscribe! If you enjoyed this video, hit the ‘like’ button, leave a comment, or watch another of our videos!
