Schrödinger (wave) equation

The Schrödinger wave equation is a quantum mechanical equation that is used to measure aspects of a particle in a quantum system. It was pioneered by theoretical physicist Erwin Schrödinger.
The Schrödinger (wave) equation in this most simple form can be written H^ Ψ = ΕΨ.

H^ is called the Hamiltonian operator, and is written as H with a hat ^ but I can’t type that lmao.
