KNOW PHYSICS

STATISTICAL MECHANICS: A BRIEF HISTORY Statistical mechanics was initiated in 1870 with the work of Austrian physicist Ludwig Boltzmann, much of which was collectively published in Boltzmann's 1896 lectures on gas theory. Statistical mechanics provided a molecular level interpretation of microscopic thermodynamic quantities such as eork, heat, free energy and entropy. The study of statistical physics is mainly classified into categories. These are: Classical statistics or Maxwell-Boltzmann statistics. Quantum statistics or Bose -Einstein and Fermi-Dirac statistics. STATISTICAL BASIS Statistics is that branch of science which deals with the collection, classification and tabulation of numerical data as the basis of explanation, description and comparison of various phenomenon. When statistical concepts are applied to physics, the new branch that emerges is called statistical physics. Statistical physics deals with macroscopic systems. i.e. the system consisting
