Kinematics and Stresses from the Lagrangian Point of Viewrelativistic theories of materials was felt especially towards 1960, that is in the years when people attached in various ways the problem of constructing more or less general theories of elasticity in general relativity.

Introductionations of electromagnetism are not invariant for Galilean transformations, but are invariant for Lorentz transformations. Moreover Michelson’s famous experiment of 1881 can be explained by assuming that light propagation in vacuum is isotropic. This excludes the possibility of determining one privileged inertial space or . space .. .可互换 发表于 2025-3-26 06:44:50

Therefore the historical hints to be considered in this section—some of which were briefly given in § 13—will mainly concern relativistic theories of elasticity.陈列 发表于 2025-3-26 10:24:17
