Answer» Answer: This fact can be most simply illustrated in Einstein's scientific writings. As a first example, I turn to one of my favorite manuscripts in his archive. It is a lengthy manuscript in his handwriting, of around 1920, titled, in translation, "Fundamental Ideas and Methods of Relativity." It contains the passage in which Einstein revealed what in his words was "the happiest thought of my life" [der gluecklichste Gedanke meines Lebens] – a thought experiment that came to him in 1907: nothing less than the DEFINITION of the equivalence PRINCIPLE, later developed in his general relativity theory. It OCCURRED to Einstein – thinking first of all in visual terms, as was usual for him – that if a man were falling from the roof of his HOUSE and tried to let anything drop, it would only move alongside him, thus indicating the equivalence of acceleration and gravity. In Einstein's words, "the acceleration of free fall with respect to the material is therefore a mighty argument that the postulate of relativity is to be EXTENDED to coordinate systems that move nonuniformly relative to one another . . . ." |
