BOHR NIELS. THE FOUNDATION OF BOHR'S ATOMIC THEORY
On the Theory of Decrease of Velocity of Moving Electrified Particles on passing through Matter
London Taylor & Francis 1913. 8vo. Bound in one nice contemporary half calf binding with gilt leather title-label to spine. Published in "The London Edinburgh and Dublin Philosophical Magazine and Journal of Science" Vol. 25. No. 145-150 offered. Small repair to spine and blind stamped to lower part of title page. The Bohr papers: pp. 10-31. Entire volume: VIII 876 pp. 10 plates. � Bohr's seminal first work on nuclear physics being the work that lays the foundation for his atomic theory published before his "On the Constitution of Atoms and Molecules" in which he is able to conclude "that a hydrogen atom contains only 1 electron outside the positively charged nucleus and that a helium atom only contains 2 electrons outside the nucleus ." <br><br>"Bohr's 1913 paper on alpha-particles i.e. the present which he had begun in Manchester and which had led him to the question of atomic structure marks the transition to his great work also of 1913 on that same problem. While still in Manchester he had already begun an early sketch of those entirely new ideas." Pais p. 128. The present work must be considered one of the most important to the birth of modern atomic theory.<br><br>After finishing his studies in Copenhagen Bohr went to Cambridge in order to pursue his studies on electron theory under the guidance of J.J. Thompson. Thompson who was beginning to lose interest in the subject by now did however not recognize the genious of the young Bohr and as soon as he could Bohr went to Manchester where Ernest Rutherford had established a laboratory. "There from March to July 1912 working with utmost concentration he i.e. Bohr laid the foundation for his greatest achievements in physics the theory of the atomic constitution." DSB. Bohr's survey of the implications of Rutherford's atomic model had led him to attack the much harder problem which lay at the core of it namely determining the exact nature of the relation between the atomic number and the number of electrons in the atom. "Bohr obtained a much deeper insight into the problem by a brilliant piece of work which he - working as he said "day and night" - completed with astonishing speed" DSB that paper being the present "On the Theory of the Decrease of Velocity of Moving electrified Particles on passing through Matter" which thus constitutes his very first publication on the subject published immediately after this dense period of 1912 in the Philosophical Magazine of January 1913. <br><br>"The problem was one of immediate interest for Rutherford's laboratory: in their passage through a material medium alpha particles continually lose energy by ionizing the atoms they encounter at a rate depending on their velocity. Their energy loss limits the depth to which the particles can penetrate into the medium and the relation between this depth or range and the velocity offers a way of determining this velocity. What Bohr did was to analyze the ionizing process on the basis of the Rutherford model of the atom and thus express the rate of energy loss in terms of the velocity by a much more accurate formula than had so far been achieved-a formula in fact to which modern quantum mechanics adds only nonessential refinements" DSB. In the present work Bohr was thus able to conclude: "In this paper the theory of the decrease of velocity of moving electrified particles in passing through matter is given in a form such that the rate of the decrease in the velocity depends on the frequency of vibration of the electrons in the atoms of the absorbing material." as well as the seminal words that have been formative for the birth of the modern atomic theory: "Adopting Prof. Rutherford's theory of the constitution of atoms it seems that it can be concluded with great certainty from the absorption of alpha-rays that a hydrogen atom contains only 1 electron outside the positively charged nucleus and that a helium atom only contains 2 electrons outside the nucleus ". Bohr continues: "These questions and some further information about the constitution of atoms which may be got from experiments on the absorption of alpha-rays will be discussed in more detail in a later paper." pp. 30-31 of the original paper - the last sentence referring directly to his three part "On the Constitution of Atoms and Molecules" in which he went on to present his postulates of the orbital structure of the electrons and their quantized radiation. <br><br>Rosenfeld Bohr Bibliography No. 5.

BOHR NIELS. THE FOUNDATION OF BOHR'S ATOMIC THEORY PRESENTATION COPY
On the Theory of the Decrease of Velocity of Moving Electrified Particles on passing through Matter. Off-print From the Philosophical Magazine Vol. 25 No. 145 for January 1913 .
London Taylor & Francis 1913. 8vo. Original printed wrappers. The fragile wrappers are detached but fully intact. Merely tiny parts of the thin backstrip lacking. Three small tears to front wrapper no loss as well as a couple of creses. Back wrapper with a slight bend to the corner and minor fading to extremities. Pp. 9-31. � Scarce first edition off-print issue with presentation-inscription of Bohr's seminal first work on nuclear physics being the work that lays the foundation for his atomic theory published before his "On the Constitution of Atoms and Molecules" in which he is able to conclude "that a hydrogen atom contains only 1 electron outside the positively charged nucleus and that a helium atom only contains 2 electrons outside the nucleus ." <br><br>"Bohr's 1913 paper on alpha-particles i.e. the present which he had begun in Manchester and which had led him to the question of atomic structure marks the transition to his great work also of 1913 on that same problem.

The present work must be considered one of the most important to the birth of modern atomic theory.<br><br>The work is inscribed to renowned Danish physicist and meteorologist Dan la Cour 1876-1942 son of the great Poul la Cour 1846-1908 who is considered the "Danish Edison". The inscription reads as thus: "Hr. Docent Afdelingschef D. la Cour/ med venlig Hilsen/ fra/ Forfatteren." In Danish i.e.: "Mr. Assistant Professor Head of Department D. la Cour/ with kind regards/ from/ the author.".<br>Dan la Cour was the assistant of Niels Bohr's father Christian Bohr and a well known scientist. From 1903 he was head of the department of the Meteorological Institute and from 1923 leader thereof. From 1908 he was Associate Professor at the Polytechnic College. His original scientific works are highly respected as are his original apparati for measuring earth magnetism which are considered highly valuable. "His original intelligence which in many ways resemble that of his father also bore fruit in his patenting of various inventions: the "Pyknoprobe" developed to quickly determine the different layers of the sea; a use of termite in quickly heating food and drinks out in the open under unfavourable weather conditions." From the Danish Encyclopaedia - own translation. He wrote a number of important and esteemed works and was member of the Danish Scientific Academy as well as many prominent international scientific commissions of meteorology and geophysics i.e. president of the International Geodetical and Geophysical Union. He was also honorary Doctor at the George Washington University. <br><br>After finishing his studies in Copenhagen Bohr went to Cambridge in order to pursue his studies on electron theory under the guidance of J.J.

Original printed wrappers. With the ownership signature of Danish physicist Mogens Pihl Prof. of physics at Copenhagen University 1957-77. 651 pp. <br>Second paper: Published in 'Zeitschrift f�r Physik' vol. 69 pp.56-69.

With rubber stamp of Danish physicist Christian M�ller Author of "The Theory of Relativity 1952". � First editions of these fundamental papers in the development of quantum field theory. The process of measuring electromagnetic fields involves the observation of charged test bodies in those fields. Therefore the theory of electrodynamics is an inseparable extension of mechanics. A quantum theory of fields thus inherits in some form the limitations of measurement which lie at the foundation of quantum mechanics. In 1931 Landau and Peierls published a critical analysis of the consequences of such limitations in a relativistic quantum theory of fields second paper offered. Landau and Peierls came to the negative conclusion that in several cases the concept of momentum was without physical meaning and quantities such as the strength of a field was un-measurable. In their famous paper from 1933 Bohr and Rosenfeld first paper offered carefully reviewed the arguments of Landau and Peierls and showed through the use of particular measuring arrangements that a consistent quantum theory of fields is possible without further limitations than the ones which secure the consistency of quantum mechanics. The BR-paper is often credited with having laid the foundation for quantum electrodynamics. Bohr continued his work in this field and in 1937 he completed a manuscript entitled "Field and Charge Measurement in Quantum Theory" but this was never published. When in the late 1940s the important work on QED by Tomonaga Schwinger Dyson and Feynman appeared in The Physical Review Bohr and Rosenfeld again joined and published the essentials of the 1937 manuscript in the same journal third paper offered.<br><br>See Abraham Pais: Bohr's Times pp.358-364.

Boiano Ilaria
Femminismo e processo penale
br. E' in corso un'ampia riflessione giuridica sulle norme penali volte a punire la violazione del diritto delle donne di vivere libere dalla violenza, ma essa rimane ancora distante dai luoghi di riproduzione dei rapporti tra i sessi e, forse ancor di più, dalle donne che tentano di destrutturarli nelle loro singole vite. Questo libro prova ad accorciare tale distanza domandandosi, attraverso la narrazione dei casi concreti decisi dalle autorità giudiziarie nazionali e internazionali, se e in che misura il diritto possa rappresentare un possibile strumento di trasformazione della vita delle donne. In particolare, indaga gli effetti dell'irruzione delle donne quale "soggetto imprevisto" dell'ordinamento giuridico e illustra come esse, sia in quanto persone offese dal reato sia in quanto giuriste, contribuiscano alla ricostruzione di pezzi di realtà e di conseguenza del discorso giuridico, sottraendo terreno agli stereotipi sessisti e impedendo che la reazione degli uomini e dell'ordinamento possa contrastare la loro libertà e autonomia. Prefazioni di Tamar Pitch e Teresa Manente.

BOLZANO BERNARD. THE FIRST WORK ON INFINIT NUMBERS AND SET THEORY
Paradoxien des Unendlichen. Herausgegeben aus dem schriftlichen Nachlasse des Verfassers von Dr. Fr. Prihonsky.
Leipzig 1851. 8vo. Original printed wrappers. Re-stitched and with a new paper backstrip perfectly matching the wrappers. Possibly lightly washed . Housed in a custom-made red cloth box with a gilt red morocco title-label to spine. XII 2 134 pp. � The exceedingly scarce first edition of this landmark work of logical and mathematical thought in which Bolzano anticipates by decades Cantor's work on Infinite Numbers lays the foundation for set theory and becomes a precursor Cauchy Cantor and Weierstrass in the arithmetization of mathematical analysis. Needless to say the work which calls for a total arithmetization of mathematical analysis was highly praised and admired by by the most important logicians in the field Peirce Dedekind and Cantor.<br><br>"Paradoxes of the Infinite is a landmark in modern mathematical and logical thought. Bolzano recognized the necessity in analyzing the paradoxes of infinity of defining various "obvious" mathematical concepts including that of continuity . Certain of the mathematical implications of his simple and obvious statement about continuity are utterly astonishing' J.R. Newman The world of mathematics p. 241. <br><br>"In 'Paradoxes' Bolzano became the first mathematician to note that an infinite set could be considered equivalent to certain of its subsets. Thus for example the sets of positive whole numbers is equivalent to the set of positive even numbers although it is clear that the set of even numbers is only a subset of the set of whole numbers. . The property of infinite sets noted by Bolzano was later used by C. S. Pierce to define precisely the concepts of finite and infinite sets. . Bolzano actually laid the foundations for set theory. He also was a precursor of Cauchy Cantor and Weierstrass in the arithmetization of mathematical analysis." Styazhkin History of Mathematical Logic from Leibniz to Peano P. 143-4.<br><br>The work was published three years after the author's death and Bolzano had to await posthumous fame for his revolutionizing masterpiece a fate befalling many that are so much ahead of their time. "Bolzano was a forerunner of important theories and ideas in various areas of knowledge. Many of Bolzano's ideas had to be discovered anew since Bolzano's preparatory work remained unknown in many cases and has come to light only from historical research." SEP <br><br>"Unlike Leibniz Bolzano was an unequivocal champion of the absolute infinite. Cantor particularly admired Bolzano's attempt to show that the paradoxes of the infinite could be explained and that the idea of completed infinities could be introduced without contradiction into mathematics. In fact Bolzano's Paradoxien des Unendlichen published in 1851 received high praise from Cantor for having done an important service to mathematics and philosophy alike" Dauben Georg Cantor P. 124.<br><br>"The essential difference between Bolzano's incomplete theory of real numbers and those of for instance theory Weierstrass and Georg Cantor are marked by the shift from intentional meaning in Bolzana's work toward a general tendency to extensionality and above all by the possibility of creating new mathematical objects by means of definition by abstraction based on equivalence relations of which Bolzano was unaware. These differences also appear clearly in his Paradoxien des Unendlichen which contains many interesting fragments of general set theory." DSB<br><br>Bolzano's groundbreaking work not only influenced mathematics and logic it also profoundly affected several branches of philosophical thought of the following century. "Radically anti-Kantian though in a distinctly non-Hegelian way Bolzano was one of the first thinkers to call for a total arithmetization of mathematical analysis that avoided recourse to all intuition or intuitive models or structures. This commitment was evident in his posthumously published Paradoxes of the Infinite" Cahiers pour l'Analyse. hardcover

Storia delle dottrine politiche
brossura Maturato nell'ambito dell'esperienza didattica dei due autori, il presente manuale è stato redatto per fornire agli studenti universitari un testo esauriente, scientificamente aggiornato (e allo stesso tempo chiaro e scorrevole) della storia del pensiero politico nei suoi aspetti essenziali e più significativi. La trattazione prende le mosse dalla formazione in età moderna di un "discorso politico autonomo" che si differenzia da altri ambiti di riflessione (religione, morale, diritto), per giungere sino all'epoca contemporanea, ricostruendo anche il profilo intellettuale di autori che animano l'attuale dibattito scientifico. Il volume è articolato in una serie di capitoli e paragrafi, in cui sono ricostruiti i tratti delle problematiche via via emergenti e i profili degli autori coinvolti, ed è corredato da varie schede esplicative utili a chi intraprende per la prima volta lo studio della disciplina.

Lo potevo fare anch'io. Perché l'arte contemporanea è davvero arte
brossura Tutti, almeno una volta nella vita, davanti a un'opera di arte contemporanea abbiamo pensato: «Ma come! Questa non è arte! Lo potevo fare anch'io!». Eppure i critici ci assicurano che si tratta davvero di capolavori, e celebri collezionisti spendono cifre da capogiro per quadri che sembrano tele imbrattate. Che siano tutti impazziti? Francesco Bonami ci aiuta a capire cosa distingue un grande artista da uno pessimo, cosa ha fatto sì che Marcel Duchamp o Andy Warhol abbiano superato la prova del tempo. E se è senz'altro vero che nell'ultimo secolo l'arte si è evoluta al punto da essere quasi irriconoscibile, il lavoro di Bonami ci fa capire perché non è vero che potevamo farlo anche noi.

Bonetti Gianni
Incipit
brossura "Incipit" non è un gioco da tavolo, di ruolo o di narrazione: è un Gioco di Narrativa. Prende due o più giocatori e fa raccontar loro delle storie, li trasformaper un periodo più o meno breve in una versione disimpegnata e imprevedibile di quegli scrittori il cui nome si legge in grosso sulle copertine dei libri. Ha poche regole, quasi tutte opzionali, e molte varianti, perché non ci sono regole fisse nel raccontare.

Bonfanti Ezio; Porta Marco
Città, museo e architettura
brossura Questo libro, scritto tra la fine degli anni Sessanta e l'inizio degli anni Settanta del secolo scorso, è stato pubblicato nel 1973, appena dopo la scomparsa di Ezio Bonfanti, uno dei suoi due autori. Commissionato come una monografia sullo studio BBPR degli architetti Banfi (1910-1945), Belgiojoso (1909-2004), Peressuti (1908-1976), Rogers (1909-1969) - straordinarie figure emergenti nella cultura architettonica, non solo italiana, del '900 - per la volontà e la capacità dei suoi autori si è trasformato in un testo che osserva la cronaca dell'architettura del '900 nello specchio del lavoro dei BBPR. Un lavoro esemplare e eccezionale che, iniziato nel 1932, ha registrato e trascritto il variare delle stagioni culturali nel nostro paese, e che è stato letto da Bonfanti e da Porta alla luce della crisi di valori degli anni '60. Oggi si può dire che questo libro rappresenta contemporaneamente una lettura critica dell'architettura dei BBPR, una riflessione sull'architettura italiana alla fine del fascismo e negli anni della rinascita del paese, una immagine in trasparenza di ciò che nell'ambiente milanese furono gli anni a cavallo tra i Sessanta e i Settanta. Un periodo cruciale per l'Italia, dal quale derivarono nuove potenzialità ma anche confusioni che nei riguardi di altre culture europee ancora contribuiscono in parte a nasconderci la modernità.

Bonito Oliva Achille
Manuale di volo. Dal mito greco all'arte moderna, dalle avanguardie storiche alla transavanguardia
br. «Dall'alto della sua condizione, l'arte ammira un paesaggio non molto ameno, l'atto di frammenti e detriti che costituiscono le scorie di una storia fatta di strappi, di ragionevole e raggelante continuità. L'angelo dell'arte respira un senso della storia che si produce a balzi, a forza di lacerazioni che non consentono ricuciture o accomodanti rammendi. L'arte detiene la profonda coscienza del tempo, l'interna sapienza della sua irresistibilità. La posizione fondante dell'arte è il nomadismo, il continuo spostamento verso il proprio confine, verso l'inevitabile frattura di ogni equilibrio del linguaggio. E questo avviene attraverso la differenza dell'opera, che si rifiuta di omologarsi con le altre opere e vive la condizione solitaria della propria superba discontinuità. Il tempo rapace, di Hölderlin, rapina nel suo vortice le cose e le dissemina ai piedi dell'angelo della storia, sbigottito davanti a tanta maceria. Soltanto l'arte può arrestare tali sprofondamenti, soltanto l'angelo dell'arte può resistere allo sfaldamento e creare un alveo, un cuneo che si insinua tra i frammenti e fonda una persistenza, una resistenza ed un armistizio. Ma questo non significa parafisi o nascondimento, non significa balsamo o phármakon, bensì rispondere al dissolvimento polveroso ed anonimo del quotidiano con una accelerazione ancora più eclatante.»

Bonnet Jacques
I fantasmi delle biblioteche
br. È un organismo vivo questa biblioteca piena di fantasmi di Jacques Bonnet, collezionista di volumi, editore e traduttore. Parla dei libri come di vecchi amici, illustra gli infiniti metodi per classificarli (alfabetico, per formato, genere, colore, lingua, rilegatura, paese...), predilige ripiani in legno piuttosto che vetrine che impediscono ai libri di respirare, ignora la polvere, ci rassicura che non è necessario aver letto tutti i libri che si posseggono. Racconta dei romanzi in cui protagonisti sono i libri, di biblioteche distrutte - Alessandria, Dresda, Sarajevo - di collezioni private andate a fuoco o svendute da famelici eredi. Rievoca il suo incontro con Pontiggia con cui progettava una associazione di collezionisti (ma dovevano possedere almeno 20.000 volumi), e del disagio provato a casa di Leonardo Sciascia vedendo una edizione completa del Journal dei Goncourt che lui, francese, invece non aveva. Si interroga, infine, sul senso delle grandi collezioni nell'epoca di internet e delle consultazioni a distanza.
