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.

1820In 8° (19,5x12,1 cm); 284 pp. e 8 c. di tav. più volte ripiegate. Legatura coeva in mezza-pelle con fregi in oro al dorso (titolo impresso a secco ma scolorito). Piatti foderati con carta marmorizzata coeva. Tagli spruzzati in azzurro. Un leggerissimo ed ininfluente alone al margine basso delle prime 20 venti carte e nelle ultime 4 carte, mai fastidioso od intenso. Prima edizione francese che presenta in prima edizione le aggiunte di Molard, di questo importante trattato del grande politico ed economo inglese Thomas William Coke, I conte di Leicester (Londra, 6 maggio 1754 - Longford, 30 giugno 1842). L'autore divenne celebre per la rivoluzione agricola che impose alle sue estese proprietà agricole nel territorio del Norfolk che ebbero un tale impulso sulla produzione agricola da esser da molti paragonata agli effetti produttivi avuti della rivoluzione industriale sulla produttività inglese. Uomo di grande ingegno fu anche un appassionato bibliofilo. La sua opera è considerata come una delle principali della storia dell'agricoltura moderna. Questa edizione francese si avvale delle aggiunte di Molard che fu "Saggio emerito de l'Ecole Polytechnique, Direttore del Conservatorio Reale di Arti e Mestieri e membro onorario del Comitato consultivo delle Arti e Manifatture. L'opera, in questa prima edizione francese è arricchita di 8 belle tavole più volte ripiegate con immagini di innovative macchine agricole. Il volume oltre a trattare delle migliori tecniche di irrigazione ed al funzionamento di numerosi nuovi macchinari descrive anche la migliore organizzazione dei giardini e tratta anche dell'allevamento delle pecore. Numerosi poi sono le parti dedicate all'influenza delle nuove tecniche agricole sull'economia dei paesi che la applicano. Esemplare in buone-ottime condizioni di conservazione e assai poco comune.

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
