The tech behind the Olympics: High-speed cameras, sensors, and annoying drones

Sports pushes the science of keeping time forward. A broadcast drone hovers as Britain's Makayla Gerken Schofield competes in the freestyle skiing women's moguls. Breakthroughs, discoveries, and DIY tips sent six days a week. Athletes competing in this year's Winter Olympic Games in Milan will do so surrounded by a complex web of AI-enabled cameras, stopwatches, sensors, and fast-flying drones capable of tracking performance down to fractions of a second. The high-tech timekeeping system, the culmination of nearly a century of constant iteration, is fundamentally reshaping how viewers at home experience the Games.
