This is a revision of John Trimmer’s English translation of Schrödinger’s famous ‘cat paper’, originally published in three parts in Naturwissenschaften in 1935.
This is a translation of Schr6dinger's three-part 1935 paper 1 in Die Naturzkissenschaften. Earlier that same year there had appeared the Einstein, Podolsky, Rosen paper 2 (also famous in paradoxology) which, Schrodinger says, in a footnote, motivated his offering. Along with this article in German, Schrodinger had two closely related English-language publications.3 But the German, aside from its oneparagraph presentation of the famous cat, covers additional territory and gives many fascinating insights into Schrodinger's thought. The translator's goal has been to adhere to the logical and physical content of the original, while at the same time trying to convey something of its semi-conversational, at times slightly sardonic flavor.
Erwin Schrodinger begins by describing the classical system, using the Rutherford model of the atom. During 1934–1935, Schrodinger was primarily situated at Oxford, although he toured the United States during this period. During 1935, he received support from the Imperial Chemical Industries, London, which allowed him some leisure time in which to write an overview of the state of quantum mechanics as he saw it. While the period following the 1927 and 1930 Solvay conferences seemed to be relatively calm, a series of important papers would arrive in 1935. These included Schrodinger's view on the status of quantum mechanics as well as his famous thought experiment involving a cat. Schrodinger's work would be published in three parts in the German journal Die Naturwissenschaften . Schrodinger suggests that the Niels Bohr doctrine is “born of distress.” Almost all the important figures in quantum mechanics were also there—Bohr, Schrodinger, W. Heisenberg, Wolfgang Pauli, Enrico Fermi, and both de Broglies.
The original Schrödinger’s paper is translated and annotated in honour of the 70 −th anniversary of his Uncertainty Relation [will appear in Bulg.J.Phys.]. In the annotation it is shown that the Uncertainty Relation can be written in a complete compact canonical form. ANNOTATION by A. Angelow ++, M.-C. Batoni +++ The main reason to publish the original Schrödinger’s paper in English, is the fact that no one of the books on Quantum Mechanics cites it (see for example [1 †-15 †]). Actually, Schrödinger’s paper is chiefly based on the notes of the seminars of Physics-Mathematical Section of The Prussian Academy, where many famous physicists worked to establish the underlying basis of Quantum Theory. Being a kind of internal report, this work remained, for many years at a certain marginal distance from the physicist scientific awareness. Another argument in favour of its oblivion concerns the enthusiastic discussions, mostly about the physical interpretation of the uncertainty principle, rather than its mathematical straightforward derivation. After Schrödinger, the very first appearance of the new uncertainty
