Two identical balls of mass m are attached via a pair of identical springs (spring constant k) and looped around a frictionless cylinder of radius R

The top ball is then displaced along the cylinder by a distance d, while the bottom ball is held fixed. At...

Why does the Schrodinger equation depend on conservation of energy if conservation of energy is violated

The Schrodinger equation:-((h^2)/8 pi m)(d^(2)psi(x)/dx^2)+v(x)psi(x)=E psi(x)is just another way of writing :kinetic energy + potential energy = total energy right? ...
