Sir Frederick William Herschel's Discoveries

The video explores the historical fascination with stars, focusing on Sir Frederick William Herschel, an astronomer and musician known for discovering Uranus. It details his experiment in 1800, where he measured the heat of different colors in the light spectrum, leading to the discovery of infrared radiation, a type of light invisible to the human eye.
