... where h̄ = h/2π. ν is linear frequency and ω is angular frequency. The fundamental constant h is called Planck’s constant and is equal to 6.62608 ×10−34 Js (h̄ = 1.05457 × 10−34 Js, or 1.05457 × 10−27 erg s). This relation was first proposed by Planck in 1900 to explain the properties of black body ...

... For example, the quantum system of an electron subject to the Coulumb potential of a nucleus of charge Z sitting at the origin is described by (1) with U (x) = −Z/|x|. Note that the form and the role of the potential is exactly the same as in classical mechanics, but instead of the velocity-square f ...
