‎Ni’ersi Bo’er ji [Chinese, i.e. ""Niels Bohr Collected Works""]. Vols. 1-10 [out of 12]. - [WITH DEDICATION FROM THE TRANSLATOR]‎

‎Shanghai, Huadong shifan daxue chubanshe, 1986 - 2001. 8vo. 10 volumes, all in publisher's uniform full cloth bindings with gilt lettering to spines and front boards. All volumes with presentation inscription from the translator to Niels Bohr's son, Ernest Bohr: ""To Mr. Ernest Bohr with / highest respect from / GeGe"". A fine and clean set of the first 10 volumes of Niels Bohr Collected Works.‎

‎First Chinese, and overall, translation of 'Niels Bohr Collected Works' with dedication inscription from the translator ot Bohr's son Ernest Bohr. Translator Prof. Ge Ge found Bohr’s personality and mode of thinking in harmony with traditional Chinese culture, which may be part of the explanation for his lifelong dedication to Niels Bohr and his work, and his great effort to translate and publish the only non-English edition of the Niels Bohr Collected Works in existence today. The first volume in English had appeared in 1972, and Ge Ge was able to publish a Chinese translation in 1986, fourteen years later.Ge Ge’s enthusiasm not only led to the Collected Works being published with impressive promptness in China, but no doubt provided additional motivation for the Director of the Niels Bohr Archive to prepare the volumes faster. In this way, Ge Ge had an influence even on the publication of the original edition. In 2001 Ge Ge received the prestigeousDanish Order of the Dannebrog “for hiscontribution to increasing the Chinese understanding of Danish science and promoting the Denmark-China scientific cooperation. He was in fact able to translate all the volumes of the Collected Works, the last volume of which was published in English in 2006. It testifies to Ge Ge’s dedication that he enthusiastically went on with the work in spite of having lost his eyesight" he died the following year. The volumes contain the following: Vol. 1: Early Work (1905-1911) Vol. 2: Work on Atomic Physics (1912-1917)Vol. 3: The Correspondence Principle (1918-1923) Vol. 4: The Periodic System (1920-1923)Vol. 5: The Emergence of Quantum Mechanics (mainly 1924-1926) Vol. 6: Foundations of Quantum Physics I (1926-1932) Vol. 7: Foundations of Quantum Physics II (1933-1958) Vol. 8: The Penetration of Charged Particles through Matter (1912-1954)Vol. 9: Nuclear Physics (1929-1952) Vol. 10: Complementarity beyond Physics (1928-1962) ‎

Robb : A alpha ray - En 1907, Ernest Rutherford obtient un poste de professeur à l'Université de Manchester, où il travaille avec Hans Geiger, avec qui il invente un compteur permettant de détecter les particules alpha émises par les substances radioactives (ébauche du futur compteur Geiger), car en ionisant le gaz qui se trouve dans l'appareil, elles produisent une décharge détectable. En 1908, avec un de ses étudiants, Thomas Royds, il prouve définitivement ce qu'on supposait, à savoir que les particules alpha sont bien des noyaux d'hélium. Ou plutôt, que les particules alpha sont des atomes d'hélium une fois débarrassés de leurs charges négatives. Pour le prouver, il isole la substance radioactive dans un matériau suffisamment mince pour que les particules alpha le traversent effectivement, mais pour que cela bloque toute « émanation » des éléments radioactifs, c'est-à-dire tout produit de la désintégration. Il recueille ensuite le gaz qui se trouve autour de la boîte qui contient les échantillons et analyse son spectre. Il y trouve alors une grande quantité d'hélium : les noyaux que sont les particules alpha ont récupéré des électrons disponibles. Il obtient la même année le prix Nobel de chimie « pour ses recherches touchant la désintégration des éléments [chimiques], et la chimie des substances radioactives2 ». Il en conserve cependant une certaine déception, car il se considère avant tout comme un physicien. Une de ses citations célèbres est : « La science, soit c'est de la physique, soit c'est de la philatélie », voulant sans doute signifier par là qu'il plaçait la physique au-dessus des autres sciences. C'est en 1911 qu'il fait sa plus grande contribution à la science en découvrant le noyau atomique. Il avait observé à Montréal qu'en bombardant une fine feuille de mica avec des particules alpha, on obtenait une déflexion de ces particules. Geiger et Marsden, refaisant de façon plus poussée ces expériences en utilisant une feuille d'or, avaient constaté que certaines particules alpha étaient déviées de plus de 90 degrés. Rutherford émet alors l'hypothèse qu'au centre de l'atome devait se trouver un « noyau » contenant presque toute la masse et toute la charge positive de l'atome, les électrons déterminant en fait la taille de l'atome. Geiger et Marsden vérifièrent par la suite ces conclusions par l'expérience. - Ce modèle planétaire avait été suggéré en 1904 par un Japonais, Hantaro Nagaoka, mais était passé inaperçu on y objectait que les électrons auraient dû rayonner en tournant autour du noyau central et donc y tomber. Les résultats de Rutherford montrèrent que ce modèle était sans doute le bon, puisqu'il permettait de prévoir avec exactitude le taux de diffusion des particules alpha en fonction de l'angle de diffusion et de la taille de l'atome. Les dernières objections théoriques sur le rayonnement de l'électron tombèrent avec le début de la théorie quantique et l'adaptation par Niels Bohr du modèle de Rutherford à la théorie de Planck, démontrant ainsi la stabilité de l'atome de Rutherford.

‎One of the few scarce original stenciled copies of the ""Journal of Jocular Physics, Vol. III,"" the 1955-volume of the privately circulated amateur-comedy-journal that Bohr's students made on the occasions of Bohr's most important birthdays (beginning with his 50th in 1935), in this case his 70th. The ""Journal"" is an eclectic blend of funny and clever stories, songs, poems, aphorisms, humorous descriptions of recent developments in physics, etc., all written in an informal tone with the underlying subject being Bohr's birthday.Since 1929 most of the greatest physicists of the 20th century had been gathering around Niels Bohr for a conference in Copenhagen at the Bohr Institute. Since 1931 this conference had also included a skit prepared by the youngest of the participants, the ""Copenhagen Faust"" of 1932 being the most famous and important of them. It is this skit that later develops into the ""Journal of Jocular Physics"" which was prepared and compiled for Bohr's 50th, 60th and 70th birthdays, the first in 1935, the second in 1945, and the third (the present) in 1955. The 1955 ""Jocular Physics"" was the last of them. ""The early decades of the present century witnessed the heady development of the Quantum Theory of the atom, and during that era the roads of theoreticians of all nationalities led, not to Rome, but to Copenhagen, the home city of Niels Bohr, who was the first to formulate the correct atomic model. It became customary at the end of each spring conference at Blegdamsvej 15 (the street address of Bohr's Institute of Theoretical Physics) to produce a stunt pertaining to recent developments in physics.However Copenhagen was also the home of abundant humor. As a respite from the intensive and highly competitive efforts taking place to characterize fundamental interactions on an atomic scale, physicists took the time to develop satirical letters, articles, plays and other works.""

The atomic revolution having opened for the scientists a new world of quanta led soon to the nuclear fission discovery and to the first steps in techniques to dominate the atomic energy. The realization of national atomic programs which first took place in USA and then in Russia (USSR) and Great Britain had attracted the whole world's attention and placed Physics and the natural sciences in general in a top position.

‎Den uhyre sjældne første danske udgave af Hemmingsens Postil, ja faktisk findes kun 2 komplette eksemplarer på private hænder, nemlig det som var ejet af Tore Virgin indtil 1947 og et eksemplar som for nogle år siden dukkede op i Frankrig, og som nu er i en dansk privatsamling. Lauritz Nielsen anfører, at der alene er registreret 4 komplette eksemplarer i offentlige biblioteker (KB, Linköping, Stifts-og Landsbibliotek, Karen Brahe, Odense og Herzog August Bibliothek, Wolfenbüttel). Universitetsbibliotekets eksemplar er defekt, ligesom KB ejer 3 defekte eksemplarer ud over det komplette, som alle 3 er med mange mangler.Postillen udkom først på Latin i 1561 og blev fortsat med ialt 16 Latinske udgaver - alle i 8vo-, og om alle kan man vist sige, at de er af største sjældenhed. Carl S. Petersen kalder Niels Hemmingsen ""den største teologiske Videnskabsmand, der har levet i vor Fædreland"", og som elev af Melancton må han nok betegnes som den mest betydelige tænker i Reformationstidens Danmark og Norge. Hans Postil er ikke egentlige prædikener, ""men dispositioner til saadanne, udarbejdede med det formål at tvinge præsten til alvorlig gennemtænkning af den hellige Text"". Samtiden tildelte ham navnet ""Danmarks almindelige Lærer"". AN ILLUSTRATIONERNE: En dansk bogsamler og ekspert på danske 1500-tals tryk (Jørgen Jark) har bidraget til opklaringen af de monumentale illustrationers ophav. Han anfører, at signaturen CE (i Thesaurus og Birkelund fejllæst som CF) - ifølge Nagler ""Die Monogramisten"" - sandsynligvis står for kunstneren, mester Endele. Han var af Wittenbergskolen, og denne serie af billeder var tidligere anvendt i en tysk udgave af Luthers Postil. Et par af billederne er mærket med årstallene 1561 og 1562. Efter lånet til Danmark må de være returneret, da de ikke optræder senere i noget andet dansk tryk. Træskæreren har markeret sig med en træskærerkniv og et 4tals-agtigt tegn, der er et i tiden og tidligere ofte anvendt laugsmærke. Et par af billederne tilhører en helt anden serie, f.eks. Del I, blad 71b. De tilskrives Hans Brosamer og hele denne serie blev brugt af Matz Vingaard i hans Lutherpostil 1577.Lauritz Nielsen: 886. - Thesaurus I, 100. - Bibl. Danica I:499. - Birkelund, 31. The exceedingly scarce first edition of the first Danish edition of Hemmingsen’s Postil. Only two complete copies are known on private hands, one that was owned by Thore Virgin up until 1947, and another copy that appeared in France some years back and which is now in a Danish private collection. According to Lauritz Nielsen, merely four complete copies are registered in libraries world-wide (Royal Library in Danmerk, Linköping’s Stifts- og Landbibliotek, Karen Brahe in Odense, and Herzog August Bibliothek in Wolfenbüttel). The copy in the University Library in Denmark is defective, as are the three other copies that The Royal Library owns, all very incomplete. Hemmingsen’s Postille first appeared in Latin in 1561, followed by another 15 Latin editions, all in 8vo. All 16 editions are considered exceedingly rare. Carl S. Petersen calls Niels Hammingsen ”the greatest theological scientist that has ever lived in our country” (i.e. Denmark). As a pupil of Melanchthon, he is rightfully considered the most significant thinker during the Danish/Norwegian Reformation. His Postil does not cosntitute actual sermons, but ”dispositions for such, prepared with the goal of forcing the priest into serious contemplation of the holy Text.” (Own translation from Danish). By his contemporaries, Hemmingsen was known as “The common teacher of Denmark”. THE ILLUSTRATIONS: A Danish bibliophile and expert on 16th century printings (Jørgen Jark) has contributed to solve the question of the origin of the monumental illustrations. He states that according to Nagler in “Die Monogramisten”, the signature CE (in Thesaurus and Birkelund erroneously read as CF) most likely refers to the artist Master Endele. Endele was part of the Wittenberg School, and this series of illustrations had previously been used in a German edition of Luther’s Postil. A few of the illustrations bear the years 1561 and 1562. After having been lent to Denmark, they must have been returned, as they appear in no other Danish printing. The woodcutter has marked himself with a woodcutter’s knife and a sign resembling “4”, which was a commonly used guild mark of the period. A few of the illustrations belong to a completely different series, e.g. Part 1, f. 71b. They are attributed to Hans Brosamer" his enire series was used by Mats Vingaard in his Luther’s Postil from 1577. Lauritz Nielsen: 886. - Thesaurus I, 100. - Bibl. Danica I:499. - Birkelund, 31.‎

‎Original unpublished manuscript translation of ""Egil's Saga"" into English, done in the mid-19th century by renowned Danish philologist Niels Matthias Petersen, first professor of the Nordic languages in Denmark, predating the first published English translation with circa 50 years. Egil's saga is generally considered amongst the best and most beloved of the Icelandic sagas. Based on Petersen’s industriousness and diligent work in having his research and translations published and the many third party textual and grammatical corrections throughout the text, the present translation was most likely intended for publication. It is not evident exactly when the translation was made nor it is clear from which text/manuscript it is translated. Petersen spent time on a Danish translation of Egil’ saga in the period 1835-1839 and it is likely that the present English translation also was made then. For Petersen’s Danish translation (In the Four volume-work: “Historiske Fortællinger om Islændernes Færd”, 1839-1844) he used the second printed edition of Egil's saga from 1809. It was produced for the Arnamagnæan Commission by Gudmundur Magnússon. It has a short introduction in Latin, followed by the text of the saga and a parallel translation in Latin. This text is in the main based on that of Codex Mödruvallensis (Ms. No. 132. Fol.) in the Arnamagaean Collection. It is highly likely that Petersen also used the 1809-edition for this present English translation. The saga spans the years c. 850-1000. Its oldest manuscript (a fragment) dates back to 1240 AD, and comprises the sole source of information on the exploits of Egill, whose life is not historically recorded. Stylistic and other similarities between Egill's Saga and Heimskringla have led many scholars to believe that they were the work of the same author, Snorri Sturlasson. Not until 1893 was an English translation published. It was translated by W. C. Green from the original Icelandic “Egils saga Skallagrímssonar”. Eddison, author of epic fantasy novels and occasional member of the Inklings, judged it as ""being so bad as to be unreadable"". Eddison thought that the saga ‘perhaps the finest of all except Njal’ deserved better, and that Egil Skallagrimson, the ‘most typical of the true viking spirit’, should be brought to a wider audience – consequently Eddition made his own translation in 1930. The syntax and vocabulary in this translation are deliberately archaic in order to maintain the style of the Icelandic. Three later English translations were made: Gwyn Jones (1960), Christine Fell (1975) and Hermann Pálsson and Paul Edwards (1976). The most recent English translation is in The Complete Sagas of Icelanders (1997). Niels Matthias Petersen (1791-1862), linguist, philologist, historian and literary historian, is regarded as being the father of modern Danish saga-studies. During his school years he befriended Rasmus Rask, his senior by four years, who kindled his interest in Old Norse and the ancient history of the Nordic countries. During his theological studies, which did not lead to a formal graduation, he pursued these interests. After working as a teacher in a seminary near Odense in the period 1815-26, he returned to Copenhagen, where he remained for the rest of his life. His first linguistic publications appeared in 1826.In 1829, Petersen entered the employment of the University Library, then of the Danish central archive. In these years he published a major language history (1829-30), a work on Denmark's early history (1834-37) and a translation and edition of a large portion of the Icelandic sagas (1839-44). ""He was the first to publish a substantial collection of Icelandic sagas in translation, ten sagas in four volumes under the title ""Historical accounts of the dealings of the Icelanders at home and abroad"" (Historiske Fortællinger om Islændernes Færd hjemme og ude, 1839-44). Petersen's aim was to present the sagas as enjoyable reading for the general public, and to strengthen the Danish language by introducing Old Norse-Icelandic neologisms.In 1845 Petersen was appointed to the first professorship in the Scandinavian languages in the Nordic countries, a position he kept to his death in 1862. In this period he wrote the modestly-titled, but comprehensive and groundbreaking five-volume ""Contribution to the history of Danish literature"" (Bidrag til den danske Literaturs Historie, 1853-61). In this work Petersen introduces into Danish the theory of periodization, and several of his period titles have survived in later accounts. His concept of literature was not restricted to imaginative writing but encompassed the entire body of writings valued in society. For Petersen, literature not only documents and reflects the nation's culture, but also exercises a formative influence on it."" (Encyclopedia of Romantic Nationalism in Europe).

‎Postillen udkom først på Latin i 1561 og blev fortsat med ialt 16 Latinske udgaver, alle kan man vist sige, af største sjældenhed. Carl S. Petersen kalder Niels Hemmingsen ""den største teologiske Videnskabsmand, der har levet i vor Fædreland"", og som elev af Melancton må han nok betegnes som den mest betydelige tænker i Reformationstidens Danmark og Norge. Hans Postil er ikke egentlige prædikener, ""men dispositioner til saadanne, udarbejdede med det formål at tvinge præsten til alvorlig gennemtænkning af den hellige Text"". Samtiden tildelte ham navnet ""Danmarks almindelige Lærer"".ANG. ILLUSTRATIONERNE: En dansk bogsamler og ekspert på danske 1500-tals tryk (Jørgen Jark) har fornylig bidraget til opklaringen af de monumentale illustrationers ophav. Han anfører, at signaturen CE (i Thesaurus fejllæst som CF) - ifølge Nagler ""Die Monogramisten"" - sandsynligvis står for kunstneren, mester Endele. Han var af Wittenbergskolen, og denne serie af billeder var tidligere anvendt i en tysk udgave af Luthers Postil. Et par af billederne er mærket med årstallene 1561 og 1562. Efter lånet til Danmark må de være returneret, da de ikke optræder senere i noget andet dansk tryk. Træskæreren har markeret sig med en træskærerkniv og et 4tals-agtigt tegn, der er et i tiden og tidligere ofte anvendt laugsmærke. Et par af billederne tilhører en helt anden serie, f.eks. bind I, blad 71b.

Ernest Rutherford (1871-1937), "Analysis of the Gamma Rays from Radium D and Radium E" et "Analysis of the Gamma Rays of the Thorium and Actinium products" : le physicien néo-zélandais publie ici ses recherches à propos des rayons gamma provenant du radium D et radium E puis du thorium et de l'actinium. Il a créé le nom de rayonnement gamma et les a déjà divisés en deux groupes en fonction de leur puissance pénétrante. ? Henry Moseley (1887-1915), "The High-Frequency Spectra of the Elements": l'élève, puis le collaborateur de Rutherford, a mené les expériences de cet article dans son propre laboratoire. Le scientifique britannique cherche à y mesurer les spectres de rayons X en plaçant les éléments dans des tubes sous vide puis en les bombardant d'électrons. Grâce à ce dispositif, il mettra en évidence la loi de Moseley qui met en relation les longueurs d'onde des rayons X et le numéro atomique des éléments, concept qu'il découvre et nomme. Cet découverte permettra de compléter le tableau périodique de Mendeleïev de ses éléments encore non connus. Bel ensemble d'articles scientifiques novateurs dans leur édition originale.

‎The Structure of the Atom. (Rutherford) + (Darwin:) Collision of 'alpha' Particles with Light Atoms. + (Bohr:) On the Effect of Electric and Magnetic Fields on Spectral Lines‎

‎London, 1914. No wrappers, but stiched. All three papers contained in: ""Philosophical Magazine"", Sixth Series, Vol. 27. No. 159. March 1914. The whole issue issue offered (=no. 159): pp. 397-540 and 2 plates.Rutherford's paper.pp. 488-498. - Darwin's paper: pp. 499-506. - Bohr's paper: pp. 506-523. All clean and fine.‎

‎First edition and first printing of all three papers. Rutherford, in this paper for the first time identifies the hydrogen nucleus, and called it the 'positive electron'. He later called it 'the proton' . In his definitive paper of 1911 he estimated the radius of the nucleus, a hundred thousand times smaller than that of an atom. Darwin in his paper (offered here) gave a more precise measure.In the first lines of the paper Rutherford outlines the content ""The present paper and and the accompanying paper by Mr. C. Darwin (the second paper offered here) deal with certain points in connection with the ""nucleus"" theory of the atom which were purposely omitted in my first communication on that subject (Phil. Mag. May 1911). A brief account is given of the later investigations which have been made to test the theory and of the deductions which can be drawn from them. At the same time a brief statement is given of recent observations on the passage of alpha particles through hydrogen, which throw importent light on the dimensions of the nucleus."" - Rutherford had studies alpha-particles intensely in the years before 1914 and proved quite conclusively that the individual particle was a helium atom with its electrons removed. The alpha particles were like the positive rays that had been discovered by Goldstein (1886), and now in 1914 (the paper offered) Rutherford suggested that the simplest positive rays must be those obtained from the hydrogen and that these must be the fundamentall positively-charged particle. He names it a 'positive electron'.Darwin, in the paper offered ""concluded from the known data:""No force proportional to some power of the distance other than the inverse square can give the dependence (the Rutherford scattering cross section) on (the initial velocity)"", and he then calculated the distance of closest alpha-particle-nucleus approach.The paper by Niels Bohr relates to ""The Stark effect"". In 1913 appeared ""an importent new discovery: when atomic hydrogen is exposed to a static electrical field its spectral lines split, the amount of splitting being proportional to thefield strenght (the linear Stark effect). After Rutherford read this news in ""Nature"", he at once wrote to Bohr:'I think it is rather up to you at the present time to write something on....electric effects.'"" (A. Pais). Bohrs paper on The Stark effect appeared in 1914, the paper offered here. - Rosenfeld. Niels Bohr' publications No. 10).‎
