Brian Cox traces how Britain became a launchpad for modern science, from Isaac Newton's laws of motion and gravity to the institutions and experiments that followed. The film moves through key sites and demonstrations, including a hydrogen explosion used to illustrate the physics at stake, connecting historical breakthroughs to the scientific method as it developed in British universities and learned societies. Cox presents the material as a host on location, walking through archives, laboratories, and landmarks tied to the scientists he discusses, rather than delivering a straight lecture to camera. The throughline is institutional as much as personal: how the Royal Society and its culture of experiment and peer scrutiny turned individual insights, Newton's chief among them, into a repeatable system for producing knowledge. The result is a survey of a few centuries of British science that treats the ideas and the country's role in organizing them as equally important, closing with a sense of how much of the modern scientific method traces back to this particular history.
