Planck Presents Quantum Theory

Date: December 14, 1900 • Location: Berlin, Germany

Quantum mechanics: Max Planck presents a theoretical derivation of his black-body radiation law (quantum theory) at the Physic Society in Berlin.

Quantum mechanics, also known as quantum physics, is the fundamental physical theory that describes the behavior of matter and of light; the behaviors it models typically occur at and below the scale of atoms, and have often been described as counterintuitive. Its concepts and methods have been applied across many disciplines, including quantum chemistry, quantum biology, quantum field theory, quantum technology, and quantum information science.
