Following Einstein’s thoughts about the dualism of waves and particles, Schrödinger takes a different route to the completion of quantum theory. In 1926, he expands de Broglie’s idea of matter waves as an explanation of the Bohr atom model. To do this, he introduces a wave equation for electrons - the famous Schrödinger Equation. Soon after, Schrödinger finds the proof that his formalism is, for the most part, equivalent to that of Heisenberg.
