'The birth of the time-dependent Schrödinger equation was perhaps not unlike the birth of a river. In the new study, the scientists have shown that it's possible to obtain the Schrödinger equation from a simple mathematical identity, and found that the mathematics involved may help answer some of the fundamental questions regarding this important equation.Īlthough much of the paper involves complex mathematical equations, the physicists describe the question of the Schrödinger equation's origins in a poetic way: Schleich, et al., from institutions in Germany and the US, explain that physicists usually reach the Schrödinger equation using a mathematical recipe. In a new paper published in PNAS, Wolfgang P.
