General physics

Electron shell

Physics; General physics

An electron shell may be thought of as an orbit followed by electrons around an atom's nucleus.

Taylor series

Physics; General physics

A Taylor series is a representation of a function as an infinite sum of terms that are calculated from the values of the function's derivatives at a single point.

In quantum mechanics, a two-state system (also known as a TLS or two-level system) is a system which has two possible states. More formally, the Hilbert space of a two-state system has two degrees of ...

Double-slit experiment

Physics; General physics

The double-slit experiment, sometimes called Young's experiment, is a demonstration that matter and energy can display characteristics of both waves and particles, and demonstrates the fundamentally ...

WKB approximation

Physics; General physics

In mathematical physics, the WKB approximation or WKB method is a method for finding approximate solutions to linear partial differential equations with spatially varying coefficients.

Wigner's friend

Physics; General physics

Wigner's friend is a thought experiment proposed by the physicist Eugene Wigner; it is an extension of the Schrödinger's cat experiment designed as a point of departure for discussing the Quantum ...

Wigner quasi-probability distribution

Physics; General physics

The Wigner quasi-probability distribution (also called the Wigner function or the Wigner–Ville distribution after Eugene Wigner and Jean-André Ville) is a quasi-probability distribution.
