Soft cover. Condition: New. Albert Einstein, "Interferenzeigenschaften des durch Kanalstrahlen emittierten Lichtes" AND Emil Rupp, "Über die Interferenzeigenschaften des Kanalstrahllichtes", in Sitzungsberichte der Preussischen Akademie der Wissenschaften 25, 1926. Berlin, Verlag der Akademie der Wissenschaften, volume 25/26, pp 333-357, with the Einstein on pp 334-340 and the Rupp on pp 341-351. Original wrappers. There is some slight discoloration to the pale green wrappers along the spine edges, otherwise this is in fine condition. __+__ Aha these two papers are the seat of a famous/infamous scandal in the history of physics, something that I am going to Very Badly Name: "The Famous E Rupptian of 1926". (Oh, by Neptune's Fancy Bloated Pants, that is bad.) The two papers listed here by Einstein and Rupp form the great Einstein/Rupp scandal of 1926. Einstein's paper was a proposition to demonstrate the instantaneous emission of light instead of the classical emission over time. (In the spring of 1926, Albert Einstein proposed to Emil Rupp to do two experiments that were to probe the wave versus particle nature of light: the so-called Wire Grid Experiment and the Rotated Mirror Experiment --Jeroen van Dongen, "Emil Rupp, Albert Einstein and the canal ray experiments on wave-particle duality: Scientific fraud and theoretical bias", Historical Studies in the Physical and Biological Sciences 37 Suppl. (2007) 73-120.) Rupp was a considerable physicist and turned his powers to the experimental demonstration of the Einstein hypothesis, publishing his supporting results in this same issue (October 1926). Unfortunately, his results were shown to be fake/fabricated, and with that entered into a different sort of history than he expected. This sort of thing doesn't seem to happen all that often so far as I can tell, though this one was a doozy. __+__ In July, 1926, at a session of the Prussian Academy of Sciences, he announced his new conviction that all interference experiments would conform to a classical description of the radiation process. He had corresponded with Rupp on the matter of doing experiments on the question, and the Proceedings of the Prussian Academy (Berlin Academy) for October 1926 [the issue offered here] contain a paper by Einstein presenting at length his new view of the matter, followed immediately by a paper by Rupp describing experiments he claimed to have made in support of Einstein s conclusions.The reported results of both experiments (by Rupp) supported Einstein s conclusion that the interference behavior of the emitted light agreed with what would follow from a classical picture of the emission process. --A.P. French, "The Strange Case of Emil Rupp", Physics in Perspective, I, 3-21, 1999. In any event, these are the source papers for a controversy that would brew, then dissolve, and then return again.
