hulláfunkcióból

Hullámfüggvényből is a Hungarian term that translates to "from the wave function" in English. In quantum mechanics, the wave function, typically denoted by the Greek letter psi (Ψ), is a mathematical description of the quantum state of a system. It contains all the information that can be known about that system. The wave function itself is not directly observable, but its square (more precisely, the square of its magnitude, |Ψ|²) is related to the probability density of finding a particle in a particular location. Therefore, when we talk about deriving information or properties "from the wave function," we are referring to the process of using this mathematical entity to understand the behavior and characteristics of quantum systems. This can involve calculating probabilities, predicting the outcome of measurements, or determining the energy levels and other observable quantities of a particle or system. The concept is fundamental to understanding phenomena such as quantum tunneling, superposition, and entanglement.
