In quantum mechanics, identity of particles of the same kind (say, electrons) mathematically results in profound consequences for their collective behavior - quantum statistics of bosons and fermions. Quantum mechanics is the study of mechanical systems whose dimensions are close to the Atomic scale such as Molecules Atoms Electrons Particle statistics refers to the particular description of particles in Statistical mechanics. In Particle physics, bosons are particles which obey Bose-Einstein statistics; they are named after Satyendra Nath Bose and Albert Einstein In Particle physics, fermions are particles which obey Fermi-Dirac statistics; they are named after Enrico Fermi.
