We've explored exploration, sailed through sailing, and navigated our way around navigation, but, at last, the time has come to wrap it all up in the final part of our three part series. What better way to do it than by discussing the final invention that made it all what it is today?

Inside, you'll find information on Egyptians, Galileo, Huygens, Greece, Ptolemy, Mathematics, Science, and more. Along with one of the saddest stories we've ever told. About a man who didn't have enough time.
