... where A depends on the nature of a metal plate (called work function). Explanation was given by Einstein again, using the quantization introduced by Planck: the light consist of tiny particles which can have energy of hν only (photon). (Note that Planck opposed the use of his „uncompleted” theory!!) ...

Langevin Equation
... To understand the Brownian motion more completely, we need to start from the basic physics, i.e. Newton’s law of motion. The most direct way of implementing this is to recognize that there is a stochastic component to the force on the particle, which we only know through a probabilistic description. ...
