If you could bring one person in all of human history back to life as a healthy young adult who would it be?

Isaac Newton. Sure, the guy was a weirdo, but his genius was unparalleled. He discovered calculus, broke down the secrets of visible light, developed the laws of universal gravitation and motion, calculated the speed of sound, introduced the idea of Newtonian fluids, and invented the reflecting telescope.

If you took someone with his brains and ingenuity with the discoveries and achievements we've made in science since his time, we could potentially advance scientific knowledge by decades.
