UNPERSONS IN DIVINE ALBERT'S WORLD

Four more Ritzians (Newtonians) in Einsteiniana: Alberto Martinez, Jan Lacki, James Espinosa and Jean Eisenstaedt:

Alberto Martinez: "Does the speed of light depend on the speed of its source? Before formulating his theory of special relativity, Albert Einstein spent a few years trying to formulate a theory in which the speed of light depends on its source, just like all material projectiles. Likewise, Walter Ritz outlined such a theory, where none of the peculiar effects of Einstein's relativity would hold. By 1913 most physicists abandoned such efforts, accepting the postulate of the constancy of the speed of light. Yet five decades later all the evidence that had been said to prove that the speed of light is independent of its source had been found to be defective."

Jan Lacki: "Ritz had no time to make his theory more elaborate. He died complaining that no one, even in Göttingen, was granting his views sufficient care. His emissionist views were submitted to heavy criticism and experimental tests were later realized to show their inanity. Today, with considerable hindsight, we know the end of the story and how Einstein and Planck's views shaped our contemporary physics. While few would today contest the reality of quanta or turn their back on field theory of elementary processes, it is interesting to know that the criticisms against Ritz's conceptions were shown, since then, often wanting, if not simply incorrect. It is fair to say that if Ritz's emission theory is false, it cannot be as easily dismissed as it was thought in Ritz's times."

"THE LAST OF THE NEWTONIANS: WALTER RITZ, James Espinosa, University of West Georgia, Carrollton, GA 30118. 2005 was declared the World Year of Physics by the United Nations in order to celebrate the life and work of Albert Einstein, who helped give birth to a new age of physics. It also marks the 100th anniversary of the end of the Newtonian world view. Walter Ritz who was a classmate of Albert Einstein was the last successful Newtonian scientist of the twentieth century. A biographical sketch of his life will be given. Two great pieces of work, which have been forgotten by modern physicists but received much serious attention by his contemporaries, are the magnetic model of the atom and the emission theory of electromagnetism. The first body of work challenged quantum theory and the other challenged Einstein's special theory of relativity. A brief description of these two areas of work will be presented."

Jean Eisenstaedt: "Einstein n'a pas pris le chemin, totalement oublié, de Michell, de Blair, des Principia en somme. Le contexte de découverte de la relativité ignorera le XVIIIème siècle et ses racines historiques plongent au coeur du XIXème siècle. Arago, Fresnel, Fizeau, Maxwell, Mascart, Michelson, Poincaré, Lorentz en furent les principaux acteurs et l'optique ondulatoire le cadre dans lequel ces questions sont posées. Pourtant, au plan des structures physiques, l'optique relativiste des corps en mouvement de cette fin du XVIIIème est infiniment plus intéressante - et plus utile pédagogiquement - que le long cheminement qu'a imposé l'éther."

Einstein and the Changing Worldviews of Physics, Einstein Studies, 2012, Volume 12, Part 1, 23-37, The Newtonian Theory of Light Propagation, Jean Eisenstaedt: "Not so surprisingly, neither the possibility of a Newtonian optics of moving bodies nor that of a Newtonian gravitational theory of light has been easily "seen," neither by relativists nor by historians of physics; most probably the "taken-for-granted fact" of the constancy of the velocity of light did not allow thinking in Newtonian terms."

Of course the Einsteinian is always stronger than the Ritzian:
