Die gegenwärtige Situation in der Quantenmechanik I-III [All]. (The Present Situation in Quantum Mechanics). - [SCHRÖDINGER'S CAT]
Springer, Berlin, 1935. 4to. (256x186mm). Pages 807-812 823-828" 844-849 from volume 23 of 'Die Naturwissenschaften'. Bound together in recent attractive marbled boards (Hanne Jensen). Leather title with gilt lettering on front board. A fine and clean copy.
First edition and first announcement of Schrödinger's famous reply to the EPR-paradox (also known as Schrödinger's Cat). When in May 1935 Einstein, Podolsky and Rosen published the so-called EPR-paper in ""Physical Review"", they set out to demonstrate that the Copenhagen interpretation of quantum mechanics could not constitute a complete description of nature. The EPR-article prompted a number of responses, e.g. from Bohr, the co-founder of the Copenhagen School, who began writing his response immediately after the publication of the Physical Review article. It is this debate that Schrödinger participates in with his seminal paper on ""The Present Situation in Quantum Mechanics"", in which he presents what is now famously known as Schrödinger's Cat. Schrödinger's Cat is the name of the thought experiment that Schrödinger develops in this article and that was intended as a discussion of the EPR article.After the publication of the EPR article, Einstein and Schrödinger had begun an exchange of letters on the subject of the possibility of quantum mechanics, as interpreted by the Copenhagenists, representing reality. During this exchange of letters, Schrödinger had been inspired by Einstein's view of the problem of applying the Copenhagen interpretation of Quantum mechanics to everyday objects. But Schrödinger, in his response, took his illustration of the absurdity of the interpretation and the incompleteness of quantum mechanics a step further" he applied it to a living entity, namely a cat. Schrödinger imagines a sealed box containing a cat, a bottle of poison, a radioactive source, a Geiger counter and a hammer. When the Geiger counter detects radiation, a mechanism is switched on that makes the hammer fall the hammer breaks the bottle, and the poison kills the cat. Because it is random, when the Geiger counter will detect radiation, and because in Quantum mechanics, physical conditions are described with the aid of a wave-function that explains all possible conditions of the system, Quantum mechanics, according to the Copenhagen interpretation, would come to the conclusion that the cat in the box is both living and dead, at the same time (the wave function is made up of a superposition of the two conditions -the cat being living and the cat being dead-" the two positions collapse into one, as soon as the system is interpreted as consisting of only one condition -either dead or living cat-, with the sole possible conclusion that the cat is both). Due to Heisenberg and Bohr's independent interpretation of Quantum theory (the ""Copenhagen interpretation), Quantum theory had in 1927 developed in a direction unforeseen by Schrödinger. ""Schrödinger was ""concerned and disappointed"" that this ""transcendental, almost physical interpretation of the wave phenomena"" had become the ""almost universally accepted dogma."""" (D.S.B. XII, p. 221). His most famous and widely used attack on this interpretation was that of ""Schrödinger's Cat"". This paradox of the dead-and-alive cat vigorously illustrated the absurdity of quantum mechanics and what was necessary to describe the states within this system. The thought experiment of Schrödinger's cat turned out to be hugely influential, and has become a standard paradox within both physics and philosophy.

First apperance of Schrödinger's paper on isotopy and the Gibb's paradox. ""Schrödinger started explicitly from the previous discussion between de Hevesy and Paneth on the one hand, and Fajans on the other, summarizing the results as 'Thermodynamical diversity of isotopes in principle, in spite of their complete or nearly complete chemical replaceability'. Thus far he partially supported the view promoted by Karlsruhe physico-chemist. However, he contradicted a result which Fajans had obtained, stating that the energy set free by mixing or diffusion of the volumes, containing different isotopes of the same chemical element, was proportional to the difference of the respective atomic weights - hence a consequence, it should become arbitrarily small as the mass difference disappeared.

First appearance of Schrödinger's famous treatment of the Compton effect.""Schrödinger approached the wave mechanical treatment of the Compton effect in his own paper [the present] on a far less technical level [than Gordon]. He practically went back to the optical analogies that had stimulated the whole development in November 1925, and in which the properties of microscopic particles were described by matter waves and their propagation in homogeneous media. From such consideration, he now - a year later - drew the following conclusion: ""It is to be expected, nay, even demanded, that we should be able, by means of quite simple phase considerations…, to explain the connection between the changes in direction and frequency of the ether wave which occur in the Compton effect and the change of velocity of the electron."" (Mehra, The Historical Development of Quantum Theory)""Compton was able to account for this (lenghtening of wavelenght) by presuming that a photon of light struch an electron, which recoiled, subtracting some energy from the photon and therefore increasing its wavelenght. This made it seem that a photon acted as a particle: thus after more than a century, the particulate natuer of light, as evolved by Newton, was revived... What itamounted to was that Compton brought to fruition the view that electromagnetic radiation had both a wave aspect and a particle aspect, and that the aspect which was most evident depended on how the radiation was tested. De Broglie was, at the same time, showing that this held true also for ordinary particles, such as electrons."" (Asimov)

First printing and first appearence of these 5 papers which introduces Schrödinger's wave-equations and explains the stationary states of electrons in Bohr's theory of the atom by way of applying de Broglie's concept of electron waves. These papers are among the most important in modern physics and ""almost overnight, made Schrödinger famous"" (Brandt, Harvest of a Century).""The intensity of Schrödingers work on the problem (he found the earlier Bohr-Sommerfeld quantum theory unsatisfactory) increased as he saw that he was on the track of ""a new atomic theory"", and it reached a peak during his winter vacation in Arosa. On 27 December 1925 he wrote to Wilhelm Wien, editor of the ""Annalen der Physik"" inMunich that he was very optimistic: ""I believe that I can give a vibrating system...thatyields the hydrogen frequency levels as it eigenfrequencies."" The frequences of the emitted light rays are then obtained, as Schrödinger observed, by establishing the differences of the two eigenfrequencies respectively. ""Consequently the way is opened toward a real understanding of Bohr's frequency calculation - it is really a vibration (or, as the case may be, interference) process, which occurs with the same frequency as the one we observe in the spectroscope. I hope, that I will soon be able to report on this subject in a little more detail and in a more comprehensive fashion"" (Schrödinger's letter to Wien)...The so-called Klein-Gordon equations which Schrödinger used gives an incorrect description of the relativistic structures Schrödinger tried to describe.

It soon became apparent that he had arrived at a theory that correctly represented a the behavior of the electron to a very good approximation.

Scarce enlarged edittion of Schubert's anti-materialistic treatise. He was influenced by the Nature philosophy of Schelling and reacted strongly against a purely materialistic approach to the sciences. He expressed this in his early work, Ansichten von der Nachtseite der Naturwissenschaften (1808). Schubert, Gotthilf Heinrich von (Hohenstein, Saxony, 1780-1860, Laufzorn, Bavaria), abandoned the study of theology at Leipzig University and turned to medicine and the natural sciences, moving later to Jena. In 1819 was appointed to the chair of natural sciences at Erlangen University. In 1827 he moved to Munich University, becoming a member of the Munich Academy. He was ennobled in 1853.
