Quantum mechanics is a fundamental theory in physics, explaining the behavior of particles at the atomic and subatomic levels. It began with Max Planck's discovery of energy quanta and was further developed by Einstein, Bohr, de Broglie, Heisenberg, and Schrödinger. This text delves into the quantization of energy, the wave-particle duality, atomic structures, and the intriguing concept of quantum vacuum energy, which has implications for cosmology and quantum computing.
