Available in PDF, EPUB and Kindle. Book excerpt: Modern cosmology aims to determine the origin, evolution, and ultimate fate of the Universe. This is an area of modern science that has engendered fierce debates which have captured public interest. This book recounts the development of modern cosmology, in chapters contributed by many of the leading protagonists. It is a fascinating account of physical and observational cosmology, the great cosmological debates, important observations and the riddle of dark matter. The enormous controversy surrounding the Big Bang theory is retold in personal recollections from H. Bondi, W. McCrea, and Fred Hoyle. This is followed by chapters on the discovery of cosmic radio waves and the contributions made by radio astronomers to current cosmology. The book concludes with a tribute to some of the pioneers of cosmology.

Download or read book Rivista di Estetica 85 written by AA.VV. and published by Rosenberg & Sellier. This book was released on 2024-07-05 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This issue of the 'philosophy of the city' includes articles by scholars on a range of human sciences, from media theory to aesthetics and architectural theory. Philosophy, social ontology, cultural anthropology, aesthetics, digital hermeneutics, media theory, cognitive science: these are just some of the disciplines that contribute to the philosophy of the city. This variety of approaches doesn't necessarily result in a chaotic mix. Many of the included forms of discourse belong to the same episteme, which means there are many connections and overlaps. This is true both in the literatures of reference and in the ways of answering the question of what 'the city' is. Secondly, the texts don't focus on the city itself, but on those who live in, design, imagine and think about it. Thirdly, because these texts create a place where different ideas can live together. This is like a city, where ideas change, are built on and then rebuilt. This is what Wittgenstein wrote about in his Philosophical Investigations.

Download or read book Recent Developments in Particle Symmetries written by A Zichichi and published by Academic Press. This book was released on 2013-10-22 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent Developments in Particle Symmetries focuses on the advancements of processes, technologies, reactions, transformations, and approaches in particle symmetries. The selection first offers information on higher symmetries and deviations from unitary symmetry, including S matrix and perturbation theory and bootstrap theory of octet enhancement. The text then ponders on broken symmetries and sum rules and difficulties of relativistic U(6). Discussions focus on covariant models, unitary, Coleman's theorems, saturation of commutation relations and particle multiplets, and exact internal symmetry. The manuscript elaborates on CP violation, K decay and CP violation, and proton-antiproton annihilations at rest. The text then takes a look at the value of internal symmetries, low-energy hyperon-proton interactions, and strange resonances. Discussions focus on mesonic and baryonic resonances, hierarchy of internal symmetries, well-ordered violation of internal symmetries, and the combination of internal and geometrical symmetries in the physics of elementary particles. The selection is a valuable source of information for readers wanting to study particle symmetries.

Download or read book Old and New Problems in Elementary Particles written by G Puppi and published by Elsevier. This book was released on 2012-12-02 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Old and New Problems in Elementary Particles provides information pertinent to elementary-particle physics. This book examines the types of problems facing high-energy physicists. Comprised of 20 chapters, this book starts with an overview of the fundamental properties of Dirac poles, with emphasis on the spin, the electric-dipole moment, and the mass. This text then examines the applications of supergain antenna, which is an interesting cautionary model against an oversimplified application of the notion of indeterminacy. Other chapters explain the uninhibited adoption of a uniform and natural experimental definition of resonance or particle with respect to hadrons. This book illustrates as well how insight into strong-interaction dynamics may be improved by a precise definition of the particle-resonance concept. The final chapter deals with the derivation of the Alder–Weisberger relation, which links the ratio of the two weak coupling constants of the nucleon with an integral over pion absorption cross-sections. Physicists and researchers will find this book useful.

Download or read book 20th Century Physics written by Edoardo Amaldi and published by World Scientific. This book was released on 1998 with total page 784 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this important volume, major events and personalities of 20th century physics are portrayed through recollections and historiographical works of one of the most prominent figures of European science. A former student of Enrico Fermi, and a leading personality of physical research and science policy in postwar Italy, Edoardo Amaldi devoted part of his career to documenting, both as witness and as historian, some significant moments of 20th century science. The focus of the book is on the European scene, ranging from nuclear research in Rome in the 1930s to particle physics at CERN, and includes biographies of physicists such as Ettore Majorana, Bruno Touschek and Fritz Houtermans.Edoardo Amaldi (Carpaneto, 1908 - Roma, 1989) was one of the leading figures in twentieth century Italian science. He was conferred his degree in physics at Rome University in 1929 and played an active role (as a member of the team of young physicists known as ?the boys of via Panisperna?) in the fundamental research on artificial induced radioactivity and the properties of neutrons, which won the group's leader Enrico Fermi the Nobel Prize for physics in 1938. Following Fermi's departure for the United States in 1938 and the disruption of the original group, Amaldi took upon himself the task of reorganising the research in physics in the difficult situation of post-war Italy. His own research went from nuclear physics to cosmic ray physics, elementary particles and, in later years, gravitational waves. Active research was for him always coupled to a direct involvement as a statesman of science and an organiser: he was the leading figure in the establishment of INFN (National Institute for Nuclear Physics) and has played a major role, as spokesman of the Italian scientific community, in the creation of CERN, the large European laboratory for high energy physics. He also actively supported the formation of a similar trans-national joint venture in space science, which gave birth to the European Space Agency. In these and several other scientific organisations, he was often entrusted with directive responsibilities. In his later years, he developed a keen interest in the history of his discipline. This gave rise to a rich production of historiographic material, of which a significant sample is collected in this volume.

Available in PDF, EPUB and Kindle. Book excerpt: This study is devoted to the Sunyaev-Zeldovich (S-Z) effect, and important related topics in cluster and CMB research. S-Z science is about to be significantly enhanced by unique, multi-faceted cluster and cosmological yield, at a level of precision in accord with the high standards of the current era that was heralded by spectacular achievements in cosmological CMB research. The pedagogical reviews and technical seminars included in this volume represent most of the important current topics in S-Z work and in the astrophysics of clusters. The publication touches upon all relevant aspects of the S-Z effect and its use as a precise cluster and cosmological probe. To commemorate the 40th anniversary of the detection of the CMB by Penzias and Wilson (in 1964), there is a chapter devoted to the history of this discovery. In his fascinating account of their work, he outlines also some lessons pertinent to current scientific issues. Other chapters discuss very interesting related observational work in Europe and the US.

Download or read book Nonlinear Optical Materials written by V. Degiorgio and published by IOS Press. This book was released on 1995 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear optical materials play a pivotal role in the future evolution of nonlinear optics in general and its impact in technology and industrial applications in particular. The progress in nonlinear optics has been tremendous since the first demonstration of an all-optical nonlinear effect in the early sixties, but until recently the main visible emphasis was on the physical aspects of the nonlinear radiation matter interaction. In the last decade, however, this effort has also brought its fruits in applied aspects of nonlinear optics. This can be essentially traced to the improvement of the performances of the nonlinear optical materials. Our understanding of the nonlinear polarization mechanisms and their relation to the structural characteristics of the materials has been considerably improved. In addition, the new development of techniques for the fabrication and growth of artificial materials has dramatically contributed to this evolution. The goal is to find and develop materials presenting large nonlinearities and satisfying at the same time all the technological requirements for applications such as wide transparency range, fast response, high damage threshold but also processability, adaptability and interfacing with other materials. Improvements, besides rendering possible the implementation of nonlinear effects in devices, open the way to the study of new nonlinear optical effects and the introduction of new concepts. This book describes new concepts which are emerging in the field of nonlinear optical materials, concentrating the attention on materials which seem more promising for applications in the technology of information transmission and processing.

Download or read book Quantum Phenomena in Mesoscopic Systems written by B. L. Alʹtshuler and published by IOS Press. This book was released on 2003 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a snapshot of the vision shared by outstanding scientists on the key theoretical and experimental issues in Mesoscopic Physics. Quantum properties of electrons in solid state devices and transport in semiconducting and superconducting low-dimensional systems, are discussed, as well as the basis of quantum computing (entanglement, noise decoherence and read-out). Each chapter collects the material presented at a Varenna School course of last year, by leading experts in the field. The reader gets a flavour of how theorists and experimentalists are paving the way to the physical realization of solid state qubits, the basic units of the new logic and memory elements for quantum processing. He will be surprised in finding that mesoscopic solid state devices, which were invented only yesterday (think of the Single Electron Transistor, or the Cooper Pair Box) are currently used as charge-sensing applications in the equipment of frontier research laboratories. These devices contribute as probing systems to produce evidence on still unsettled questions in topics like the metal-insulator transition in disordered two dimensional systems, quantum Hall conductance in heterostructur"

Download or read book Plasmas in the Universe written by B. Coppi and published by IOS Press. This book was released on 2000 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book illustrates new developments in the fields of space and solar physics, stellar physics, extragalactic physics and cosmology. It also elaborates upon the progress of laboratory plasma physics. One of the topics discussed is the existence of collective processes, both linear and non-linear, that can explain key elements of accretion physics, magnetic reconnection, the formation of 'strange' particle distributions, particle scattering phenomena, etc. Astrophysical plasma are dominated by turbulent or quasi-turbulent processes which interactively associate instabilities, radiation processes and plasma-wave scattering. The resulting scenario, which is outside thermodynamics and conventional statistical physics, is too difficult to describe theoretically, but today there are large-scale experiments and powerful computational tools allowing for the exploration of an almost similarly complex variety of phenomena. Several contributions to this book present indications of the influence of nonlinear phenomena in astrophysical applications. This work marks the fast growth of plasma astrophysics thanks to new observations in the high energy band of the spectrum on the one hand and the possibility of validating and bringing to light relevant new theories by increasingly sophisticated machines on the other.

Download or read book Physics of NMR Spectroscopy in Biology and Medicine written by B. Maraviglia and published by Elsevier. This book was released on 1988-09-01 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of the recent expansion of nuclear magnetic resonance in biomedicine, a number of workshops and schools have been organized to introduce the NMR principles to a wider group of biologists, radiologists, neurologists, etc. The aim of most of these courses was to provide a common vocabulary and enough information about ``pulse sequences'', relaxation times, etc. in order to facilitate the use of the various types of NMR imaging systems. However, no courses were organized for the physicists who were responsible for the origin and evolution of the ideas in this area. This Enrico Fermi school was therefore organized. The topics discussed included the theoretical interpretation and prediction of NMR signals, the study of new imaging techniques up to the building of special r.f. coils and the study of new methods for analysing NMR data in the time domain.
