Schrödinger Wave Equation: Derivation & Explanation

What is the Schrodinger Equation? The Schrödinger equation (also called Schrödinger’s wave equation) is the partial differential equation that governs how the wave function of a non-relativistic quantum system changes with time. Solving it gives the allowed energies and the probability amplitude for finding the system in space. It does not give a classical trajectory. … Read more

Heisenberg Uncertainty Principle: Equation & Explanation

What is the Heisenberg Uncertainty Principle? The Heisenberg Uncertainty Principle says a quantum particle cannot have an arbitrarily sharp position and an arbitrarily sharp momentum at the same time. The usual statement is that the product of those spreads is at least ħ/2. That position-momentum bound is the case that appears in popular science. The … Read more
