1955réf. 3554907258891955. Symmetry of Physical Laws - Part 1 Symmetry in Space -Time and Balance Theorems & Part 2 Q-Number Theory of Space-time Inversions and Charge Conjugation. Published by: U.S. Naval Postgraduate School Monterey California circa 1955-1956. Two stapled papers offprints from Review of Modern Physics - Reprinted from Review of Modern Physics Vol 27 No. 1 pp 26-39 and pp 40-76 January 1955 printed in the U.S.A". Watanabe Satoshi 26 May 1910 15 October 1993 was a theoretical physicist. He studied various topics such as the time reversal of quantum mechanics pattern recognition cognitive science and the concept of time. He was the first physicist who claimed that quantum probability theory is time-asymmetric irreversible; non-invariant under time reversal and reject the conventional analysis of the time reversal of probability laws. He developed the Double Inferential Vector Formalism DIVF later known as the Two-state vector formalism TSVF which is sometimes interpreted as contradicting his claim of time-asymmetry but this is a misunderstanding. Watanabe investigated how symmetries in space-time relate to various "balance theorems" which are consequences of inversibility and reversibility. EXTREMELY RARE AND IMPORTANT. No results on COPAC.

1721réf. 1880Bordeaux: R Brun 1721. First Edition. later marbled bds. A very good copy; old ownership stamp on frt. pastedown. 12mo. There is one fldg. eng. plate. A 'disgusting outrage' is how Perceval characterised his incarceration for madness in the early 1830s. He was forced into asylums on three separate occasions between 1831 ans 1833. He was in the 'care' of a Dr. Fox near Bristol. The experiences related in this memoir were typical of the treatment of the day. As a result of his experiences Perceval spent the remainder of his life seeking to redress the conditions and protect those who were unjustifiably confined. This is an important memoir and a remarkable copy of the book. Poggendorff I 500; DSB III 484-'86; Roberts Cat. p. 83 - ' very rare '. R Brun unknown books

In: "The Physical Review. A Journal of Experimental and theoretical Physics" Vol. 24 Second Series. V704 pp. textillustr. Van Vleck's papers: pp. 330-346 a. pp. 347-365. Internally clean and fine. First appearance of Van Vleck's two importent papers in which he clarifies and extends the Principle of Correspondence."Van Vleck made his greatest contribution to the old quantum theory in 1924 when he conceived his correspondence principle for absorption. He demonstrated that in the limit of high quantum numbers there would be a correspondence between absorption by classical multiply periodic systems and by their quantum analogues. His proof depended on interpreting net absorption in the quantum theory as the difference between gross absorption and stimulated emission of radiation an interpretation prompted by a remark of Breit’s. Van Vleck was particularly pleased that his classical theory reproduced the quantum result without the need for stimulated emission which he referred to as "negative absorption." DSB."Van Vleck’s theory of absorption by multiply periodic systems was consistent with the newly derived Kramers theory of dispersion and it convinced Bohr that his correspondence principle applied not only to emission but also to absorption. Further Van Vleck’s 1924 calculation made use of several of the ideas that Werner Heisenberg used in his matrix mechanics a year later. Van Vleck’s work however did not lead in the direction of matrix mechanics. His intent was to explain quantum phenomena especially "negative absorption" in classical terms rather than to devise an internally consistent quantum theory." DSB.In 1977 he shared the Nobel Prize with Philip Anderson and N. F. Mott.Van der Waerden "Sources of Quantum Mechanics" pp. 203 ff. hardcover
