Measuring India | Part 1: William Lambton and the Trigonometrical Survey

Mount Everest has been an enigma for centuries. While an object of worship historically, it presented itself as a tantalising puzzle to the measurement-obsessed surveyors of the East India Company. However this puzzle presented itself in the way it did, only because of an ambitious enterprise that sought to answer a much more fundamental question: What is the exact shape of the earth? In the first of a two-episode deep dive, we look into the exploits of William Lambton, who pioneered India's first 'Big Data' exercise called Great Trigonometrical Survey of India. The Rearview is a podcast where the hosts guide you on a scenic route through the history of science. Filled with fascinating anecdotes, deep archival dives, and a closer look at the quirky minds behind groundbreaking ideas. Hosts: Jacob Koshy and Sobhana K Nair Edited and produced by Jude Francis Weston
