By knowing the shape of our Earth we can create maps, survive the oceans, follow rivers, navigate the skies, and travel across the globe. This is the story of our world, of how we discovered what no one thought possible – the shape of the earth. This is a thrilling account of the first major expedition by data gatherers and qualified observers to interior Peru, to discover the shape and magnitude of the Earth.
