‎Le musicologue Alfred Einstein (Munich, 1880 - Californie, 1952) s'est signalé par sa magistrale étude des “Madrigaux italiens”, par son “Mozart”, par sa révision du Catalogue Köchel, par celle du “Dictionnaire de musique” de Riemann, par ses articles de la “Berliner Tageblatt”. Fuyant le régime hitlérien, il gagne Londres en 1933 et les Etats-Unis en 1939. D'année en année, sans trop insister sur la biographie, Alfred Einstein s'attache aux oeuvres révélatrices de la vie intérieure. Son Schubert est un esprit indépendant, même vis-à-vis de Beethoven. C'est un être d'intimité, "seul au piano", qui ne cherche ni les jeux d'esprit ni les applaudissements. C'est un romantique, par sa joie sensuelle sur fond de tristesse, son rapport tout immédiat à la sonorité, sa palette de peintre du sentiment ; il lui arrive d'anticiper en toute précocité les trouvailles wagnériennes et modernes ; mais c'est un "classique du romantisme", chez qui le souci de poésie n'affaiblit jamais la musique. N'étant "pas de ce monde", il crée pour s'en accommoder, mais la mort lui est une douce amie. Sans dissertations, ce livre fait naître maintes idées, souvent reprises dans les études schubertiennes depuis un quart de siècle. Bref, c'est un ouvrage classique. Désormais les frais d'envoi sont de 6 € seulement pour les livres jusqu'à 1 kg (colissimo suivi), pour la France métropolitaine.‎

‎First editions, in the scarce offprint versions, of Einstein's last and highly important contributions to General relativity, and in which is shown that the equation of motion follows directly from the field equation that defined the geometry.""Einstein's last importent contribution to general relativity deals again with the problem of motion. It is the work done with Leopold Infeld and Banash Hoffmann on the N-body problem of motion. In these papers, the gravitational field is no longer treated as external. Instead, it and the motion of its (singular) sources are treated simultaneously. Anew approximationscheme is introduced in which the fields are no longer necessarily weak but in which the source velocities are small compared with the light velocity .... The equations obtained have found use in situations where Newtonian interaction must be included. '(These equations) are widely used in analyses of planetary orbits in the solarsystem. For example, the Cal Tech Jet Propulsion Laboratory uses them, in modified form, to calculate ephmerides for high-precision tracking of planets and spacecraft.""(Pais ""Subtle is the Lord"", p. 290-91).""The problem of the equation of motion of bodies is the following. The 1916 theory had a classical structure in the sense that there were both field equations (the curvature of space-time is determined by the mass and motion of bodies in space-time) and equations of motion of bodies (the world line of small mass is a geodesic). Are these two statements really separate? If the field equations were linear, they indeed would be. They are not linear, however, and Einstein showed (in the papers offered) that if matter is represented by a point singularity of the metric field, these singularities are located on world lines that are geodesics of space-time, provided its metric satisfies the equation of general relativity.""(DSB).Weil: 202 a. 295 (both with an asterix denoting a major paper). - Boni: 236 a. 236.1.‎

‎First printing of Einstein and Rosen's answer to Silberstein's critique of Einstein's Theory of Relativity ..""Ludwik Silberstein, who initially was a supporter of the special theory, objected at different occasions against general relativity. In 1920 he argued that the deflection of light by the sun, as observed by Arthur Eddington et al. (1919), is not necessarily a confirmation of general relativity, but may also be explained by the Stokes-Planck theory of complete aether drag. However, such models are in contradiction with the aberration of light and other experiments (see ""Alternative theories""). And in 1935, Silberstein claimed to have found a contradiction in the Two-body problem in general relativity. However, also this claim was refuted by Einstein and Rosen (1935) (in the paper offered).""(Wikipedia).‎
