The asynchronous formulation of relativistic statics and thermodynamics

Abstract

An exposition of the covariant asynchronous formulationA of relativistic statics and thermodynamics is given, and this description is compared with the traditional synchronous oneS. The spin equation is given a covariant formulation. Also the equation of motion for extended bodies is given inA. Further the interpretation inS and inA of the elements of the energy-momentum tensor is stated, and the result is employed on an ideal gas. The relativistic concept of heat is discussed. The temperature is introduced as a scalar. Some examples from the statics, the right-angled lever, Trouton and Noble’s experiment and Sears’ relativistic paradox, are discussed. A few topics from the relativistic thermodynamics, the transformation of energy and momentum of an ideal gas and the transformation of thermodynamical work between inertial systems, are treated in some detail. Also the exchange of heat between systems with a relative motion is described and discussed.
