THE GRAVITATIONAL EQUATIONS FROM A VARIATIONAL PRINCIPLE. First editions extremely rare author's presentation offprint not to be confused with the much more common trade separate - see below from the library of the great German physicist Arnold Sommerfeld of Einstein's derivation of the field equations of gravitation from a variational principle. This was the first time Einstein had derived the field equations of gravitation in arbitrary coordinates - in his celebrated 1915 papers he derived the equations in generally-covariant form but only in special 'unimodular' coordinates. In the early 19th century William Rowan Hamilton 1805-65 showed that Newton's equations of motion for a classical mechanical system were equivalent to the statement that the 'action' of the system now called the Lagrangian has a stationary value generally a minimum. A first variational approach to the gravitational field equations of general relativity was unsuccessfully sketched by Einstein and Marcel Grossmann in 1913-1914 and subsequently by Einstein himself in 1914 the so-called Entwurf Theory. But Einstein's 1914 theory was invalidated by a misconception related to the physically unjustified requirement of restricting the covariance of the gravitational field equations and by some mathematical errors in a crucial proof in the theory. Between March and May 1915 the Italian mathematician Tullio Levi-Civita 1873-1941 in his private correspondence with Einstein singled out the mathematical flaws of the Entwurf theory setting Einstein back on the path of general covariance which eventually brought him in November 1915 to the correct formulation of the gravitational field equations. Also in November 1915 the great German mathematician David Hilbert 1862-1943 published an article in which he correctly showed that Einstein's gravitational field equations could be obtained from a variational principle at least in the presence of an electromagnetic field. Five days later independently of Hilbert Einstein obtained in the present paper the same results thus obtaining the definitive variational formulation of the field equations. Einstein considered his approach to be more general than Hilbert's as Hilbert had made some hypotheses about matter which Einstein dispensed with Einstein also refused to accept the electromagnetic origin of matter which Hilbert had assumed. In the course of this paper Einstein also proved a special case of Emmy Noether's second theorem on the relation between symmetry and conservation laws which she published in full generality two years later. The only author's presentation offprint listed on RBH is that is the collection of Einstein's son Hans Albert Christie's 2006; it was not in Einstein's own collection of his offprints Christie's 2008. Provenance: Arnold Sommerfeld 1868-1951 his characteristic numbering in red pencil '34' on front cover; Institut für Theoretische Physik Munich ink stamp on upper cover. "The son of a physician Sommerfeld was educated at the University of Königsberg. After teaching briefly at the universities of Göttingen Clausthal and Aachen he was appointed professor of physics at the University of Münich in 1906. Sommerfeld should have retired in 1936 in favour of his pupil Werner Heisenberg. Opposition from the Nazi party to Heisenberg's appointment prolonged Sommerfeld's tenure and it was not in fact until late 1939 that he finally retired to be succeeded not by Heisenberg but by Wilhelm Müller a Nazi aerodynamicist without a single publication in physics to his credit. Although Sommerfeld and Heisenberg were not Jewish they were regarded by the Nazis as Jewish sympathizers. Sommerfeld however survived the war and returned to his Münich chair in 1945 continuing to work at physics until he died in a car accident in 1951" Oxford Reference. "Arnold Sommerfeld was one of the most distinguished representatives of the transition period between classical and modern theoretical physics. The work of his youth was still firmly anchored in the conceptions of the nineteenth century; but when in the first decennium of the century the flood of new discoveries experimental and theoretical broke the dams of tradition he became a leader of the new movement and in combining the two ways of thinking he exerted a powerful influence on the younger generation. This combination of a classical mind to whom clarity of conception and mathematical rigour are essential with the adventurous spirit of a pioneer are the roots of his scientific success while his exceptional gift of communicating his ideas by spoken and written word made him a great teacher" Max Born p. 275. "Einstein's first paper on a metric theory of gravity co-authored with his mathematician friend Marcel Grossmann was published as a separatum in early 1913 and was reprinted the following year in Zeitschrift für Mathematik und Physik. Most of the formalism of general relativity as we know it today was already in place in this Einstein-Grossmann theory. Still missing were the generally-covariant Einstein field equations . "In the fall of 1915 Einstein came to the painful realization that the 'Entwurf' field equations are untenable. Casting about for new field equations he fortuitously found his way back to equations of broad covariance that he had reluctantly abandoned three years earlier . on November 4 1915 presented the rediscovered old equations to the Berlin Academy. He returned a week later with an important modification and two weeks after that with a further modification . "When it was all over Einstein commented with typical self-deprecation: 'unfortunately I have immortalized my final errors in the academy-papers;' and 'it's convenient with that fellow Einstein every year he retracts what he wrote the year before.' What excused Einstein's rushing into print was that he knew that the formidable Göttingen mathematician David Hilbert was hot on his trail. Nevertheless these hastily written communications to the Berlin Academy proved hard to follow even for Einstein's staunchest supporters such as the Leyden theorists H. A. Lorentz and Paul Ehrenfest . Ehrenfest's queries undoubtedly helped Einstein organize the material of November 1915 for an authoritative exposition of the new theory . "In March 1916 Einstein sent his new review article 'Die Grundlage der Relativitätstheorie' to Wilhelm Wien editor of the Annalen . In this paper the field equations and energy-momentum conservation are not developed in generally-covariant form but only in special coordinates. Einstein had found the Einstein field equation in terms of these coordinates in November 1915. This part of the review paper is basically a sanitized version of the argument that had led Einstein to these equations in the first place . "As he was writing his review article he was already considering redoing the discussion of the field equations and energy-momentum conservation in arbitrary coordinates. In November 1916 he published such a generally-covariant account in the Berlin Sitzungsberichte the offered paper. This paper is undoubtedly much more satisfactory mathematically than the corresponding part of the review article but it does not offer any insight into how Einstein actually found his theory. Reading the offered paper without having read the November 1915 papers and the 1916 review article one easily comes away with the impression that Einstein hit upon the Einstein field equations simply by picking the mathematically most obvious candidate for the gravitational part of the Lagrangian for the metric field namely the Riemann curvature scalar. This is essentially how Einstein himself came to remember his discovery of general relativity. He routinely trotted out this version of events to justify the purely mathematical speculation he resorted to in his work on unified field theory. "In this paper he derived the generally-covariant field equations from an action principle with the Riemann curvature scalar as the Lagrangian . The present paper fills two important gaps in the review article. First Einstein derived the generally-covariant version of the Bianchi identities which in conjunction with the field equations imply energy-momentum conservation . Second Einstein showed that the identities guaranteeing energy-momentum conservation are a direct consequence of the covariance of the action functional. Einstein had thus in a mathematically impeccable way found a special case of one of Noether's theorems published two years later. "From a purely mathematical point of view the discussion of the field equations and energy-momentum conservation in the present paper is far more elegant than in the review article. This more elegant treatment however obscures the way in which Einstein found the Einstein field equations. It makes it look as if it was a matter ofpicking the most obvious candidate for the Lagrangian the Riemann curvature scalar at which point everything else fell into place. Ironically this is exactly what Einstein in his later years came to believe himself in part no doubt because it made his successful search for the field equations of general relativity look so similar to his fruitless search for a unified field theory. The clumsier discussion in unimodular coordinates in the review article however may serve as a reminder that-whatever he believed said or wrote about it later on-Einstein only discovered the mathematical high road to the Einstein field equations after he had already found these equations at the end of a poorly paved road through physics. Serving as road signs were Newton's gravitational theory Maxwell's electrodynamics and such key results of special relativity as the law of energy-momentum conservation. Considerations of mathematical elegance played only a subsidiary role" Janssen. This author's presentation offprint is of extreme rarity and must be distinguished from other so-called 'offprints' of papers from the Berlin Sitzungsberichte many of which are commonly available on the market. The celebrated bookseller Ernst Weil 1919-1981 in the introduction to his Einstein bibliography wrote: "I have often been asked about the number of those offprints. It seems to be certain that there were few before 1914. They were given only to the author and mostly 'Überreicht vom Verfasser' Presented by the Author is printed on the wrapper. Later on I have no doubt many more offprints were made and also sold as such especially by the Berlin Academy." If the term 'offprint' means as we believe it should a separate printing of a journal article given only to the author for distribution to colleagues then 'offprints' were not commercially available. Although there is certainly some truth in Weil's remark in our view it requires clarification and explanation. Until about 1916 most of Einstein's papers were published in Annalen der Physik; from 1916 until he left Germany for the United States in 1933 most were published in the Berlin Sitzungsberichte. The Sitzungsberichte differed from other journals in which Einstein published in that it made separate printings of its papers commercially available. These separate printings have 'Sonderabdruck' printed on the front wrapper the usual German term for offprint but they are not offprints according to our definition. They were available to anyone; indeed a price list of these 'trade offprints' is printed on the rear wrapper. True author's presentation offprints can be distinguished from these trade separates by the presence of 'Überreicht vom Verfasser' on the front wrapper. In the period 1916 to 1919 or 1920 the Sitzungsberichte trade separates are themselves rare. After 1919 or 1920 however the trade separates become much more common although the author's presentation offprints are still very rare. The reason for this change is that it was only in 1919 that Einstein became famous among the general public. It might seem obvious that Einstein's fame dates from 1905 his 'annus mirabilis' in which he published his epoch-making papers on special relativity and the light quantum. However these works did not make him immediately well known even in the physics community - many physicists did not understand or accept his work and it was two or three years before his genius was fully accepted even by his colleagues. Einstein did not secure an academic position until 1908. Among the general public Einstein became well known only in late 1919 following the success of Eddington's expedition to observe the bending of light by the Sun which confirmed Einstein's general theory of relativity. This was front-page news and made Einstein universally famous. See Chapter 16 'The suddenly famous Doctor Einstein' in Pais Subtle is the Lord for an account of these events. Before 1919 the trade separates of Einstein's papers would probably only have been purchased by professional physicists; after 1919 everyone wanted a memento of the famous Dr. Einstein whether or not they understood anything of theoretical physics and the trade separates of his papers were printed and sold in far greater numbers than before to meet the demand. It is telling that when these post-1919 trade separates appear on the market they are often in mint condition - they were never read simply because their owners were unable to understand them.

This photograph was taken circa 1954 and is one of the images published in this limited edition. With An 18" x 22" blueprint folded of the Solar Eclipse Spectrograph size "C" drawing. It was made from the original drawing dated 4/1/55 drawn by Zoomar's Chief Designer Alfred Joseph Quittner "AJQ" & approved by Dr. Back "FGB". A very interesting package indeed. Dr. Back was a very close friend of Albert Einstein. Dr. Einstein persuaded the author to take the trip commemorated in this beautifully produced volume in order to capture the total eclipse of the sun which occurred on June 20 1955. Dr. Back intended to provide conclusive evidence for Einstein's theory of relativity by calculating the optical distortion if any of starlight caused by the sun's gravity. Earlier in 1919 Einstein's general relativity principles were supported by observations of a solar eclipse. The two scientists conferred on the project for over a year. Armed with a special Zoomar designed & built wide-angle solar-eclipse spectrograph Dr. Back was off to the Philippine Islands to board a military jet & chase the eclipse. Einstein however died while Back was on his way to Manila. Unable to report the excursion to his friend Dr. Back dedicated this book to his memory. Dr. Frank Back held over 200 patents directly relating to photographic equipment. He was the founder & president of Zoomar Inc. The photographic term " zoom" was derived from Zoomar. Dr. Back created the first widely used zoom lenses for motion picture and television; then in 1959 introduced the first zoom lens for still cameras with the introduction of the 36-82mm/f2.8 Voigtlander Zoomar. Dr. Back & Zoomar purchased the great Heinz Kilfitt optical factory of Munich Germany in 1966 & it became a subsidiary of Zoomar Inc. This volume was never widely distributed & when Zoomar Inc. ceased operations at Glen Cove Long Island many cases of this book were discovered & unceremoniously trashed. The existing number of copies is unknown but the book is not frequently encountered. This copy came from the personal estate of Dr. Frank Gerald Back & it is one of the few copies signed by him. An excellent example suited for collectors of Science Astronomy Einstein Zoomar or Photographic History in general. In a lovely custom clamshell case with a window insert displaying the original Einstein/Back photo. On page 13 there is a typo. He wrote July 301954 instead of June 30 1954 and was never changed.

M. S. Blackett' see below with Blackett's ownership inscription in blue ink to front free endpaper.First English edition with a preface by Einstein of this work arguing for nuclear disarmament translated by the gardener novelist and anarchist Edward Byams this copy from the library of Nobel Prize-winning physicist Patrick Blackett whose own work is discussed at length in the book.Jules Moch 1893-1985 worked as a French Resistance organiser during the war later became a senior minister in several post-war governments and was France's delegate to the UN Disarmament Committee for 1951-1960. It was this latter role that informed the principles he sets forth in Human Folly which argue for multilateral nuclear disarmament. Divided into two parts the first examines the destructive capacities of modern warfare before tracing the recent history of disarmament negotiations. Moch attempts to represent both Soviet and Western positions with fairness concluding that the divisions between the two are gradually narrowing. Though he does not regard the situation as entirely hopeless he presents it as one of pressing urgency. The preface by Albert Einstein one of Moch's most eminent supporters makes clear peace can only arise from political will: 'Those who do not believe in the possibility of the attainment of a lasting and assured peace or have not the courage to act accordingly are ripe for destruction' p. 8. Provenance: front free endpaper with the ownership inscription of Patrick Blackett 1897-1974 with his occasional underlining throughout and one word 'Target' in pencil to the top of p. 10. Blackett was awarded the 1948 Nobel Prize in Physics for his pioneering work in nuclear physics and cosmic radiation including experiments demonstrating nuclear transmutation and important early research into the positron. During the Second World War he headed Operational Research at the Admiralty where his statistical criticism of the RAF blanket bombing campaigns led to increasing ostracism from the military authority. His opposition to mass destruction later informed his belief that Britain should not develop nuclear weapons. Combined with his openly socialist views this attracted the attention of MI5 and led to his inclusion on George Orwell's list of alleged 'crypto-communists' contributing to his marginalisation by the post-war Labour government. Blackett's book The Military and Economic Consequences of Atomic Energy 1948 is discussed at length by Moch pp. 117-19. Written before the development of second-generation thermonuclear weapons Blackett had estimated that thousands of atomic bombs would be required to destroy the United States or the Soviet Union when at the time only a few dozen existed. As Moch observes on p. 121 however 'today a few dozen thermonuclear bombs would produce the same results'. It is particularly notable that Blackett has not annotated the passages explicitly discussing his work. This copy of Human Folly is offered with Blackett's pamphlet The Atom and the Charter which discusses the extent to which 'the advent of atomic bombs necessitates changes in the procedure for the application of sanctions under the Charter of the United Nations Organisation' issued by Victor Gollancz and the socialist Fabian Society on behalf of the Association of Scientific Workers a scientific trade union of which Blackett was president. hardcover
2016ill., br. Quando la sorprendente indeterminazione della meccanica quantistica travolse il mondo ordinato della fisica newtoniana, Albert Einstein e Erwin Schrödinger erano in prima linea nella rivoluzione. Entrambi però rimasero sempre insoddisfatti dell'interpretazione "ortodossa" della meccanica quantistica e si ribellarono a ciò che consideravano la sua caratteristica più irragionevole: la casualità. Einstein protestò con una battuta che "Dio non gioca a dadi con l'Universo", mentre Schrödinger costruì il celebre paradosso di un gatto che era vivo e morto contemporaneamente. Ma questi due giganti non si limitarono a opporsi, cercarono di formulare una teoria onnicomprensiva che rendesse nuovamente sensato l'Universo. Il fisico Paul Halpern racconta la vicenda di come Einstein e Schrödinger abbiano cercato di trascendere gli aspetti bizzarri dei quanti, dando ai lettori spunti originali circa la storia della fisica e raccontando l'impresa di due scienziati le cui ossessioni ne hanno guidato il progresso.

Possiamo sconfiggere la fame nel mondo? Come inizia e finisce un amore? Dalla fisica alla psicologia, dalla medicina alla filosofia, questo volume illustra il punto di vista della scienza sui grandi interrogativi che da sempre suscitano la curiosità e la riflessione degli studiosi e dell'uomo comune. Alla carrellata delle diverse teorie che, nel corso dei secoli, hanno avanzato ipotesi risolutive di questi interrogativi, si affianca la presentazione degli sviluppi più recenti che hanno aperto nuovi spiragli di indagine su alcuni dei più grandi misteri dell'esistenza.
