Thomas Young

Pioneered wave theory of light and deciphered Egyptian hieroglyphs

Thomas Young (1773–1829) was a British polymath whose work in physics, linguistics, and physiology made him one of history's most versatile scientists. Young's double-slit experiment demonstrated light's wave nature, challenging Newton's particle theory and shaping modern optics. His decipherment of the Rosetta Stone's Demotic script unlocked ancient Egyptian writing systems.

In physiology, Young's research on color vision and astigmatism revolutionized ophthalmology. As a physician, he contributed to blood pressure studies and elasticity theory. Young's interdisciplinary genius earned him the nickname 'The Last Man Who Knew Everything,' embodying the Enlightenment ideal of universal knowledge.
