Henry Cavendish was one of history’s greatest scientists and one of its most reclusive — a brilliant, painfully shy figure who weighed the Earth itself yet left much of his groundbreaking work unpublished. In this episode we explore Cavendish’s famous experiment to measure the density of the planet, his pioneering discoveries in chemistry and physics, and the eccentric, intensely private life that kept his genius hidden from the world. Learn how a man who shunned attention helped shape modern science.
