Max Planck's atomic theory revolutionized our understanding of physics and laid the groundwork for quantum mechanics. Max Planck introduced the idea that energy is quantized, meaning it comes in discrete packets called "quanta." This theory challenged classical physics, which treated energy as a continuous wave. Planck's work explained blackbody radiation, a problem that puzzled scientists for years. His constant, known as Planck's constant, became a fundamental part of quantum theory. Planck's insights opened doors to new technologies like semiconductors and lasers. Understanding these 12 facts about Max Planck's atomic theory will give you a deeper appreciation for the man who changed science forever.
