Résumé :
|
It’s a moment that you’ve always dreaded – you stepped away from your hiking buddies to take a photo, but on the way back you slipped down an embankment. Now you’re isolated, you can’t find the trail or your friends, and you’re in unfamiliar woods. You try your phone – no signal. How did people navigate before GPS, anyway? In The Lost Art of Finding Our Way, author John Edward Huth aims to show us just that. In a richly-illustrated 544 pages, Huth tries to illuminate the techniques that let man circumnavigate the globe, long before the first GPS satellite was launched.
The book is divided into roughly two halves, with the first being historical tales and discussions of techniques used by ancient navigators to find their way. The Norse are here, as are Pacific Islanders and European sailors: all have lessons to teach us about our environment, from the way that waves form around a cluster of islands, to how to use a cross-staff to estimate the position of a star on a heaving ship deck. Following this, the second half of the book is more abstract, dealing with factors useful to navigators: like weather prediction, or the factors that create the swell and tides in the ocean.
