  • A Hidden Treasure on Computer Science Pre-History in Pisa: the CSCE Collection
    Parallel Session Biagioni and Giannini A Hidden Treasure on Computer Science Pre-History in Pisa: the CSCE Collection Stefania Biagioni and Silvia Giannini, ISTI-CNR, Institute for the Science and Technologies of Information, National Research Council, Italy Abstract The collection of the Center for the Study of Electronic Computers (CSCE) contains the scientific documentation produced by the staff and associate members of the Center. The CSCE was established by the University of Pisa with the specific purpose of designing and building the first electronic computer entirely built in Italy: the CEP, standing for “Pisan Electronic Computer”. In recent times we have carried out the analysis, the description and the digitization of these historical documents, stored in paper copy at our library, and turned them into an Open Access digital archive freely available at http://csce.isti.cnr.it/. The most important historical events The history of the CSCE started at the beginning of the ‘50s, when the municipal and provincial administrations of Pisa, Lucca and Livorno granted the University of Pisa a significant amount of money (150 million liras) to be used for the realization of an important scientific device. The original idea was to build an electrosynchrotron. The studies about the construction of this electrosynchrotron began in February 1953 at the Institute of Physics of the University of Pisa, and were about to finish when a bid by the University of Rome, one of the project partners, to have the project transferred to Frascati, near Rome, was accepted; this transfer meant that the amount originally granted to the University of Pisa became available for a new project.

  • A Nature of Science Guided Approach to the Physics Teaching of Cosmic Rays
    A Nature of Science guided approach to the physics teaching of Cosmic Rays Dissertation zur Erlangung des akademischen Grades Doktorin der Philosophie (Dr. phil. { Doctor philosophiae) eingereicht am Fachbereich 4 Mathematik, Naturwissenschaften, Wirtschaft & Informatik der Universit¨atHildesheim vorgelegt von Rosalia Madonia geboren am 20.

Gutachter: Prof. Dr. Peter Grabmayr ii Abstract This thesis focuses on cosmic rays and Nature of Science (NOS). The first aim of this work is to investigate whether the variegated aspects of cosmic ray research -from its historical development to the science topics addressed herein- can be used for a teaching approach with and about NOS. The efficacy of the NOS based teaching has been highlighted in many studies, aimed at developing innovative and more effective teaching strategies. The fil rouge that we propose unwinds through cosmic ray research, that with its century long history appears to be the perfect topic for a study of and through NOS. The second aim of the work is to find out what knowledge the pupils and students have regarding the many aspect of NOS. To this end we have designed, executed, and analyzed the outcomes of a sample-based investigation carried out with pupils and students in Palermo (Italy), T¨ubingenand Hildesheim (Germany), and constructed around an open-ended ques- tionnaire. The main goal is to study whether intrinsic differences between the German and Italian samples can be observed. The thesis is divided in three parts.

  • Ritorno a Chicago: Enrico Fermi E La Nascita Della Fisica Delle Alte Energie Nel Secondo Dopoguerra (1946-1954)
    Ritorno a Chicago: Enrico Fermi e la nascita della fisica delle alte energie nel secondo dopoguerra (1946-1954) Giulio Maltese1 Introduzione: Fermi e gli “anni Cinquanta” Nella storia della fisica delle particelle, non molto dopo la fine della Seconda Guerra Mondiale cominciò un periodo al quale ci si può genericamente riferire come agli “anni Cinquanta”. Durò dal 1947 al 1963, e attraverso di esso “la fisica delle particelle elementari divenne adulta e passò attraverso ai trionfi e ai dolori della sua adolescenza. Cominciato con la scoperta dei pioni carichi nei raggi cosmici, il periodo finì con la consapevolezza che i costituenti fondamentali degli adroni sono i quarks. Questi anni videro l’affermazione della teoria quantistica dei campi nell’elettrodinamica quantistica (QED) rinormalizzata, solo per vederla rigettata come schema teorico per le interazioni forti e deboli. Videro anche il concetto di simmetria emergere come caratteristica fondamentale della fisica, per assistere poi alla sua caduta nella rivoluzione della parità. I ricercatori scoprirono particelle così diverse da ogni altra particella allora nota da coniare per esse l’appellativo “strane” trovando poi proprietà inaspettate nel comportamento di interazioni note da tempo. Gli anni Cinquanta furono un periodo di scompiglio intellettuale, dove nella fisica teorica cambiarono mode e atteggiamenti.”2 Enrico Fermi fu uno dei personaggi principali della prima metà di questo periodo. Dei quasi sedici anni che trascorse negli Stati Uniti dalla fuga dall’Europa nel dicembre 1938 fino alla sua morte prematura nel 1954, le sue imprese scientifiche più note sono la realizzazione della prima reazione a catena (2 dicembre 1942) e il test della prima bomba atomica (16 luglio 1945), avvenute rispettivamente presso il Metallurgical Laboratory di Chicago e nel deserto di Alamogordo, vicino al laboratorio di Los Alamos, nel New Mexico.

  • QUANTUM FIELD THEORY from QED to the Standard Model Silvan S
    P1: GSM 0521571995C19 0521571995-NYE March 6, 2002 13:59 19 QUANTUM FIELD THEORY From QED to the Standard Model Silvan S. Schweber Until the 1980s, it was usual to tell the story of the developments in physics during the twentieth century as “inward bound” – from atoms, to nuclei and electrons, to nucleons and mesons, and then to quarks – and to focus on conceptual advances. The typical exposition was a narrative beginning with Max Planck (1858–1947) and the quantum hypothesis and Albert Einstein (1879–1955) and the special theory of relativity, and culminating with the formulation of the standard model of the electroweak and strong interac- tions during the 1970s. Theoretical understanding took pride of place, and commitment to reductionism and unification was seen as the most impor- tant factor in explaining the success of the program. The Kuhnian model of the growth of scientific knowledge, with its revolutionary paradigm shifts, buttressed the primacy of theory and the view that experimentation and instrumentation were subordinate to and entrained by theory.1 The situation changed after Ian Hacking, Peter Galison, Bruno Latour, Simon Schaffer, and other historians, philosophers, and sociologists of science reanalyzed and reassessed the practices and roles of experimentation. It has become clear that accounting for the growth of knowledge in the physical sciences during the twentieth century is a complex story. Advances in physics were driven and secured by a host of factors, including contingent ones. Furthermore, it is often difficult to separate the social, sociological, and political factors from the technical and intellectual ones. In an important and influential book, Image and Logic, published in 1997, Peter Galison offered a framework for understanding what physics was about in the twentieth century.

  • Arxiv:1909.00679V1 [Physics.Hist-Ph] 2 Sep 2019 1Cresti M., Loria A
    Oral History Interview with Marcello Cresti by Alessandro De Angelis, August 2019 Born in Grosseto, 26 April 1928, Marcello Cresti graduated in Physics in 1950 at the University of Pisa by attending the Scuola Normale Superiore, and became professor of Experimental Physics in Padua in 1965. His research focused on the physics of cosmic rays and elementary particles. In 1951, working at the mountain observatory built by the Padua research group at Pian di Fedaia, close to the Marmolada mountain, at an altitude of 2000 m a.s.l., he developed and used a system of overlapping Wilson chambers that allowed an analysis of particles produced by cosmic rays. With this device, in collaboration with Arturo Loria and Guido Zago, he obtained results on the extended air showers of cosmic radiation and on the production of pions and strange particles.1 As other mountain observatories, the Fedaia Laboratory had an important role in establishing international collaborations with other cosmic ray groups in Europe. In 1955 he worked at the Max Planck Institute for Physics in G¨ottingen,directed by Werner Heisenberg, to analyze the data obtained, developing a technique for reconstructing events that used one of the first electronic computers, built in that Institute by Heinz Billing in the early 1950s. During his stay in G¨ottingen, he collaborated with Martin Deutschmann who brought to the Fedaia observatory a multiplate cloud chamber2 and also established a relationship with Klaus Gottstein, who later led the Max Planck cosmic ray group and with whom he later collaborated in Berkeley. In 1956/57 he worked at the UCRL (University of California Radiation Laboratory) in Berkeley under the direction of Luis W.

  • Environmental Setting, Impacts and Mitigation Measures
    CHAPTER 4 Environmental Setting, Impacts and Mitigation Measures Approach to the Analysis of Impacts This chapter consists of 12 individual sections that describe the existing environmental setting and evaluate the environmental impacts of the proposed demolition of the Bevatron and the structure housing it, Building 51. Scope of the Environmental Evaluation In accordance with Appendix G of the CEQA Guidelines and the UC CEQA Handbook, the potential environmental effects of the proposed 2020 LRDP are analyzed for the following environmental issue areas: • Aesthetics • Air Quality • Biological Resources • Cultural Resources • Geology, Seismicity and Soils • Hazardous Materials • Hydrology and Water Quality • Land Use • Noise • Public Services • Transportation and Traffic • Utilities and Service System Agricultural resources, population and housing, and mineral resources are discussed only in the Notice of Preparation (see Appendix A). Format of Impact Analysis Each of the 12 sections in this chapter includes a brief Introduction that describes the approach to the analysis of the topic at hand; a description of the existing Setting, including a discussion of existing physical conditions and of the regulatory environment for the issues under analysis; and an analysis of Impacts and Mitigation Measures. Demolition of Building 51 and the Bevatron IV-1 ESA / 204442 Draft Environmental Impact Report IV. Environmental Setting, Impacts and Mitigation Measures The impacts analysis begins by setting for the relevant Significance Criteria by which impacts will be judged. In general, these criteria are derived from Appendix G of the state CEQA Guidelines and from the UC CEQA Handbook. Because this is a tiered EIR (that is, the analyses are founded upon the analysis in the Lab’s 1987 LRDP EIR, as amended), the impacts discussion next presents a summary of relevant impacts anticipated and analyzed in the programmatic LRDP EIR, as amended, as well as mitigation measures from the LRDP EIR, as amended.
