Relativity
Max Planck was a German physicist known for his role in the development of quantum theory, which revolutionized our understanding of atomic and subatomic processes. He introduced the idea that energy is quantized, leading to the formulation of Planck's constant and the concept of energy levels, which laid the groundwork for the theories that Einstein would later build upon in his thought experiments regarding light and energy.
