Max Planck was studying blackbody radiation when he stumbled upon the principles of quantum mechanics. He was investigating how objects emit and absorb electromagnetic radiation, particularly at different temperatures. To resolve the discrepancies between experimental results and classical physics, he proposed that energy is quantized, introducing the concept of energy quanta, which laid the foundation for quantum theory. This groundbreaking idea emerged in 1900 when he formulated Planck's law of radiation.
