= First edition of Milne's controversial work " in which he introduced a new deductive system of theoretical physics which came to be called kinematic relativity. He introduced the useful term "cosmological principle" to signify that observers associated with galaxies in his model and in many others, including those based on general relativity, would see similar "world pictures". Milne went on to derive from his model many properties analogous to the laws of dynamics, gravitation, and electromagnetic theory. These developments of his theory were not generally accepted, and it is now thought that the most important effect of his work was that it led to fresh attempts to analyze the concepts of time and space-time."
