👉 In physics, a Bose-Einstein distribution is a statistical model of the number of particles in a collection. It describes how many particles are present for every unit volume of space. This type of distribution is often used to describe Bose statistics, which states that in a certain ensemble of particles, the probability of finding an object at a given location is proportional to its density (the number of particles per unit volume). The Bose-Einstein distribution arises as a limiting case of the Bose gas distribution when the temperature
