Problem with Early Navigation Tools [PDF ebook] 

It’s fascinating to think about how people ever found their way around. For instance, how did people navigate hundreds or even thousands of years ago? They likely didn’t ask for directions, as they were all alone trying to explore uncharted territory. We’ve come a long way with navigation tools, whether it’s simply following a map or something a bit more advanced. Readers discover the history of navigation, from using the sun or stars to help find the way to advanced technology like GPS. This book demonstrates how important it is to learn from the mistakes and wrong turns-only bloopers and follies have helped us develop reliable methods to find our way home!
