Physicists Prove That the Imaginary Part of Quantum Mechanics Really Exists!
SciTech Daily - Wed Apr 28, 2021
For almost a century, physicists have been intrigued by the fundamental question: why are complex numbers so important in quantum mechanics, that is, numbers containing a component with the imaginary number i? Usually, it was assumed that they are only a mathematical trick to facilitate the description of phenomena, and only results expressed in real numbers have a physical meaning. More»
