At the start of the 18th century, no one knew with any certainty the shape of the earth. Was our planet a perfect sphere or slightly squashed as Newton proposed? Master-surveyor and bestselling author Edwin Danson here presents the stories of the scientists and scholars who cut their way through jungles, crossed the artic tundra, and braved the world's highest mountains to discover the truth about our Earth. A spell-binding scientific adventure story, Weighing the World will intrigue anyone curious about the shape of our planet and how we have come to know it.
