First appearance of these milestone papers in Quantum Physics constituting the first step in Quantum Field Theory and the invention of the Second Quantifization Method. By these papers Dirac "gave the foundation for that theory quantum electrodynamics"Pais."A New Radiation Theory. Dirac liked his transformation theory because it was the outcome of a planned line of research and not a fortuitous discovery. He forced his future investigations to fit it. The first results of this strategy were almost miraculous. First came his new radiation theory in February 1927 which quantized for the first time James Clerk Maxwell’s radiation in interaction with atoms. Previous quantum-mechanical studies of radiation problems except for Jordan’s unpopular attempt retained purely classical fields. In late 1925 Jordan had applied Heisenberg’s rules of quantization to continuous free fields and obtained a light-quantum structure with the expected statistics Bose Einstein and dual fluctuation properties. Dirac further demonstrated that spontaneous emission and its characteristics—previously taken into account only by special postulates—followed from the interaction between atoms and the quantum field. Essential to this success was the fact that Dirac’s transformation theory eliminated from the interpretation of the quantum formalism every reference to classical emitted radiation contrary to Heisenberg’s original point of view and also to Schrödinger’s concept of as a classical source of field.This work was done during Dirac’s visit to Copenhagen in the winter of 1927. Presumably to please Bohr who insisted on wave-particle duality and equality Dirac opposed the "corpuscular point of view" to the quantized electromagnetic "wave point of view." He started with a set of massless Bose particles described by symmetric waves in configuration space. As he discovered by’ playing with the equations ’ this description was equivalent to a quantized Schrödinger equation in the space of one particle; this’ second quantization’ was already known to Jordan who during 1927 extended it into the basic modern quantum field representation of matter. Dirac limited his use of second quantization electromagnetic to radiation: to establish that the corpuscular point of view once brought into this form was equivalent to the wave point of view."DSB. hardcover

First printing of these 4 fundamental papers on the perturbations of the moon as Euler was the first to use of the Calculus on the motion of the moon in relation to the attractive powers of the Moon the Earth and the Sun. The theories laid down here is also called Euler's second theory and it is the most interesting. It was of the greatest importtence as a basis for later developments."He applied his mathematics to astronomy working out the nature of some perturbations being in this respect the precursor of Lagrange and Laplace. He began to replace the geometric methods of proof used by Galileo and Newton with the algebraic a tendency carried to its conclusion by Lagrange. In particular he worked on lunar theory that is on the analysis of the exact motion of the moon the complications of which have been the despair of astronomers and mathematicians since the time of Kepler. - Eneström: 398 399 400 a. 401. unknown

Clean and fine. First appearance of Le Verrier's provisional theory on the motion of Mercury his studies of which eventually did much to demonstrate the validity of Einstein's Theory of Relativity. The planetary orbits should agree with the predictions of the General Theory of relativity but as Einstein pointed out in his "Erklärung der Perihelbewegung des Merkurs aus der allgemeinen Relativitätstheorie" from 1915 the divergences predicted were too small to be observed except in the case of the nearest planet Mercury where the perihelion advance according to the formula reaches the value of 43"" per 100 years being in full agreement with the calculations of Le Verrier who found this unexplained rest in the perihelion advance of Mercury per century if the perturbations due to the other planets are deduced.- Einstein tells in a letter to a friend that for several days he was in a 'state of delirious joy' by this wonderful astronomical confirmation of his theory."Le Verrier first began to study Mercury on the suggestion of Arago in 1840. Astronomers realized that Mercury's perihelion the point at which the orbit of a planet is closest to the sun advanced along its orbit at a rate of 566 seconds per century. Le Verrier calculated that even when taking into account the forces exerted by other planets in the solar system there still existed a discrepancy between calculation and observation. Le Verrier's accurate calculations showed that the planet's perihelion.did indeed advance forty seconds of an arc per century more than could be accounted for by Newton's theory of gravitation even after the minor pertubing effects of the other planets had been allowed for." Asimov. - Le verrier published these findings in the present work carefully as to the mass of the planet comparison with other orbits of planets and their perihelia. At the time Le Verrier put down the discrepancy to mis-observation or mis-calculation.- Sparrow Milestones of Science No. 133. unknown

1617In-folio, (4), pp240, (4), legatura coeva in pelle, . Trattato volto a illustrare le virtù civiche di sentimento del bene comune e di partecipazione alla vita pubblica, dato alle stampe nel 1617. Il Cebà, di nobile famiglia genovese, fu fecondo poeta in volgare, prevalentemente imitatore, con esiti non disprezzabili, del grande modello del Petrarca, con una quantità di liriche dedicate all’amata Aurelia Spinola, morta giovane nel 1596, e a Geronima di Negro, poi fattasi monaca. Dopo gli studi a Genova e a Padova, ove ebbe maestri lo Speroni e Giasone di Nores, nel 1591 entrò nell’Accademia degli Addormentati, dedicandosi da allora esclusivamente alla professione letteraria. Traduttore di Teofrasto, lasciò anche un altro poema sacro, “Lazzaro il mendico”, nonché il dialogo teorico “Il Gonzaga ovvero del poema epico”. Treaty aimed at illustrating the civic virtues and feeling for the common good and participation in public life, first published in 1617. Ansaldo Cebà, of a noble Genoese family, was a fruitful poet in vulgar, mainly imitator, with non-despicable results, of the great model of Petrarch, with a quantity of lyrics dedicated to his beloved Aurelia Spinola, who died young in 1596, and to Geronima di Negro, who became a nun. After his studies in Genoa and Padua, with Speroni and Giasone di Nores as teachers, in 1591 he entered the Academia degli Addormentati, focusing from then on exclusively to the literary profession. Translator of Theofrastus, he also left another sacred poem, “Lazzaro il mendico”, as well as the theoretical dialogue “Il Gonzaga ovvero del poema epico” Vinciana 364, Gamba 1853,Bozza scrittori politici

Very scarce first edition of Basedow's main work in educational theory meant to explain his "Elementarwerk".He was strongly influenced by Rousseau's ideas on education in Emile and he proposed the reform of schools and of the common methods of instruction the establishment of an institute for qualifying teachers and solicited subscriptions for the printing of a new illustrated book Elementarwerk "Elementary Book" where his principles were to be explained at length assisted by "Das Methodenbuch".Basedow was called to Denmark in 1753 to become professor at Soroe Akademi where he stayed for 8 years. He was dismissed to Altona in 1761 caused by his theological views going against the prevailing orthodoxy. While he stayed in Soroe he published his "Praktische Philosophie für alle Stände" 1758. hardcover
