The quantum theory originated from the work of Niels Bohr and Werner Heisenberg. They developed the theory in the 1920s and 1930s. The theory was based on the idea that the behavior of particles could be described by a wave-like behavior. This wave-like behavior was called the wave function. The wave function was a mathematical function that described the probability of finding a particle at a certain location.
