The title of the article refers to the fact that special relativity resolves an inconsistency between Maxwell's equations and classical mechanics. The theory of special relativity was proposed in 1905 by Albert Einstein in his article ' On the Electrodynamics of Moving Bodies'. The special theory of relativity enjoys a relationship with electromagnetism and mechanics that is, the principle of relativity and the principle of stationary action in mechanics can be used to derive Maxwell's equations, and vice versa.

Central to this are the concepts of system and surroundings. In thermodynamics, interactions between large ensembles of objects are studied and categorized. They also postulate the existence of a quantity named entropy, which can be defined for any system. The starting point for most thermodynamic considerations is the laws of thermodynamics, which postulate that energy can be exchanged between physical systems as heat or work. Historically, thermodynamics developed out of the desire to increase the efficiency of early steam engines. Thermodynamics studies the effects of changes in temperature, pressure, and volume on physical systems on the macroscopic scale, and the transfer of energy as heat. By modeling matter as collections of hard spheres, it is possible to describe the kinetic theory of gases, upon which classical thermodynamics is based. The first chapter of The Feynman Lectures on Physics is about the existence of atoms, which Feynman considered to be the most compact statement of physics, from which science could easily result even if all other knowledge was lost.
