Biography
Arthur Compton revolutionized quantum physics by demonstrating that photons behave as particles with measurable momentum, earning the 1927 Nobel Prize in Physics. His discovery of the Compton Effect—the shift in wavelength when Xrays collide with electrons—provided decisive experimental proof of quantum mechanics and Einstein's photon hypothesis. Beyond research, Compton led the Metallurgical Laboratory during the Manhattan Project, shaping both atomic science and ethical discourse around nuclear weapons.
