Erwin Schrödinger is an Austrian theoretical physicist, one of the founders of quantum mechanics. His famous wave equation describes the evolution of quantum systems and allowed the explanation of the hydrogen atom spectrum. He also introduced the term 'quantum entanglement' and proposed a paradoxical thought experiment with a cat, demonstrating the complexities of quantum interpretation.

Biography

Born in Vienna. Studied at the University of Vienna. Taught at the University of Zurich, then took Max Planck's chair at the University of Berlin. After the Nazis came to power, he left Germany and worked at Oxford and the Dublin Institute for Advanced Studies. In 1926, in a series of papers, he developed wave mechanics and the Schrödinger equation. Laureate of the Nobel Prize in Physics in 1933 jointly with Paul Dirac.

Key discoveries

💡 It is believed that the idea of the wave equation came to Schrödinger during the Christmas holidays of 1925, spent at an Alpine resort with a mysterious companion. His cat paradox was conceived as sarcastic criticism of the Copenhagen interpretation but became one of the most recognizable images in science.
Quote: "The number of fundamental facts that remain uncovered is becoming fewer; a new fact can almost certainly be foreseen, and the more precisely it is foreseen, the more precise the convergence."
