The Polymath Who Made Light Interfere

Thomas Young seemed capable of mastering almost any subject he encountered. He demonstrated the interference of light, helping establish its wave nature; described elasticity through what became Young’s modulus; investigated vision and colour; and made crucial progress in deciphering the Rosetta Stone. This documentary follows the physician and polymath from his remarkable childhood through his most influential experiments, revealing how a single life connected physics, medicine, engineering, linguistics and ancient.

Young's double-slit experiment remains one of the most important demonstrations in all of physics, reappearing at the heart of quantum mechanics two centuries later. Engineers still use Young's modulus, vision science still reflects his colour theory and Egyptology remembers his work on hieroglyphs. His story offers more than a catalogue of achievements: it shows the power of moving freely between disciplines. Few lives demonstrate so clearly how curiosity in one field can unlock discoveries in another.
