Download or read book History of Virtual Work Laws written by Danilo Capecchi and published by Springer Science & Business Media. This book was released on 2012-05-11 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents a history of classical mechanics by focusing on issues of equilibrium. The historical point of view adopted here restricts attention to cases where the effectiveness of forces is assessed on the basis of the virtual motion of their points of application. For completeness, hints of the alternative approach are also referred, the Archimedean for ancient mechanics and the Newtonian for modern mechanics. The laws resulting from consideration of virtual motions are named laws of virtual work. The modern formulations of the principle of virtual work are only a particular form of them. The book begins with the first documented formulations of laws of virtual work in the IV century BC in Greece and proceeds to the end of the XIX century AD in Europe. A significant space is devoted to Arabic and Latin mechanics of Middle Ages. With the Renaissance it began to appear slightly different wordings of the laws, which were often proposed as unique principles of statics. The process reached its apex with Bernoulli and Lagrange in the XVIII century. The book ends with some chapters dealing with the discussions that took place in the French school on the role of the Lagrangian version of the law of virtual work and its applications to continuum mechanics.
Download or read book The Virtual Workplace written by Joseph A. Seiner and published by Cambridge University Press. This book was released on 2021-06-17 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent pandemic has clarified the overwhelming connection between the workplace and technology. With thousands of employees suddenly forced to work at home, a large segment of the workforce quickly received crash courses in videoconferencing and other technologies, and society as a whole took a step back to redefine what employment actually means. The virtual workplace is the blending of brick-and-mortar physical places of business with the advanced technologies that now make it possible for workers to perform their duties outside of the office. Trying to regulate in this area requires the application of decades old employment laws to a context never even contemplated by the legislatures that wrote those rules. This book explores the emerging issues of virtual work—defining employment, litigating claims, aggregating cases, unionizing workers, and preventing harassment—and provides clarity to these areas, synthesizing the current case law, statutory rules, and academic literature to provide guidance to workers and companies operating in the technology sector.
Download or read book Virtual Work Approach to Mechanical Modeling written by Jean Salençon and published by John Wiley & Sons. This book was released on 2018-02-21 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is centred about the Principle of virtual work and the related method for mechanical modelling. It aims at showing and enhancing the polyvalence and versatility of the virtual work approach in the mechanical modelling process. The virtual work statement is set as the principle at the root of a force modelling method that can be implemented on any geometrical description. After experimentally induced hypotheses have been made on the geometrical parameters that describe the concerned system and subsystems, the method provides a unifying framework for building up consistently associated force models where external and internal forces are introduced through their virtual rates of work. Systems described as three-dimensional, curvilinear or planar continua are considered: force models are established with the corresponding equations of motion; the validation process points out that enlarging the domain of relevance of the model for practical applications calls for an enrichment of the geometrical description that takes into account the underlying microstructure.
Download or read book The History of the Theory of Structures written by Karl-Eugen Kurrer and published by John Wiley & Sons. This book was released on 2018-07-23 with total page 1242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten years after the publication of the first English edition of The History of the Theory of Structures, Dr. Kurrer now gives us a much enlarged second edition with a new subtitle: Searching for Equilibrium. The author invites the reader to take part in a journey through time to explore the equilibrium of structures. That journey starts with the emergence of the statics and strength of materials of Leonardo da Vinci and Galileo, and reaches its first climax with Coulomb's structural theories for beams, earth pressure and arches in the late 18th century. Over the next 100 years, Navier, Culmann, Maxwell, Rankine, Mohr, Castigliano and Müller-Breslau moulded theory of structures into a fundamental engineering science discipline that - in the form of modern structural mechanics - played a key role in creating the design languages of the steel, reinforced concrete, aircraft, automotive and shipbuilding industries in the 20th century. In his portrayal, the author places the emphasis on the formation and development of modern numerical engineering methods such as FEM and describes their integration into the discipline of computational mechanics. Brief insights into customary methods of calculation backed up by historical facts help the reader to understand the history of structural mechanics and earth pressure theory from the point of view of modern engineering practice. This approach also makes a vital contribution to the teaching of engineers. Dr. Kurrer manages to give us a real feel for the different approaches of the players involved through their engineering science profiles and personalities, thus creating awareness for the social context. The 260 brief biographies convey the subjective aspect of theory of structures and structural mechanics from the early years of the modern era to the present day. Civil and structural engineers and architects are well represented, but there are also biographies of mathematicians, physicists, mechanical engineers and aircraft and ship designers. The main works of these protagonists of theory of structures are reviewed and listed at the end of each biography. Besides the acknowledged figures in theory of structures such as Coulomb, Culmann, Maxwell, Mohr, Müller-Breslau, Navier, Rankine, Saint-Venant, Timoshenko and Westergaard, the reader is also introduced to G. Green, A. N. Krylov, G. Li, A. J. S. Pippard, W. Prager, H. A. Schade, A. W. Skempton, C. A. Truesdell, J. A. L. Waddell and H. Wagner. The pioneers of the modern movement in theory of structures, J. H. Argyris, R. W. Clough, T. v. Kármán, M. J. Turner and O. C. Zienkiewicz, are also given extensive biographical treatment. A huge bibliography of about 4,500 works rounds off the book. New content in the second edition deals with earth pressure theory, ultimate load method, an analysis of historical textbooks, steel bridges, lightweight construction, theory of plates and shells, Green's function, computational statics, FEM, computer-assisted graphical analysis and historical engineering science. The number of pages now exceeds 1,200 - an increase of 50% over the first English edition. This book is the first all-embracing historical account of theory of structures from the 16th century to the present day.
Download or read book Continuum Mechanics Through the Eighteenth and Nineteenth Centuries written by Gérard A. Maugin and published by Springer Science & Business Media. This book was released on 2014-04-04 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conceived as a series of more or less autonomous essays, the present book critically exposes the initial developments of continuum thermo-mechanics in a post Newtonian period extending from the creative works of the Bernoullis to the First World war, i.e., roughly during first the “Age of reason” and next the “Birth of the modern world”. The emphasis is rightly placed on the original contributions from the “Continental” scientists (the Bernoulli family, Euler, d’Alembert, Lagrange, Cauchy, Piola, Duhamel, Neumann, Clebsch, Kirchhoff, Helmholtz, Saint-Venant, Boussinesq, the Cosserat brothers, Caratheodory) in competition with their British peers (Green, Kelvin, Stokes, Maxwell, Rayleigh, Love,..). It underlines the main breakthroughs as well as the secondary ones. It highlights the role of scientists who left essential prints in this history of scientific ideas. The book shows how the formidable developments that blossomed in the twentieth century (and perused in a previous book of the author in the same Springer Series: “Continuum Mechanics through the Twentieth Century”, Springer 2013) found rich compost in the constructive foundational achievements of the eighteenth and nineteenth centuries. The pre-WWI situation is well summarized by a thorough analysis of treatises (Appell, Hellinger) published at that time. English translations by the author of most critical texts in French or German are given to the benefit of the readers.
Download or read book Burchard de Volder and the Age of the Scientific Revolution written by Andrea Strazzoni and published by Springer Nature. This book was released on 2019-11-18 with total page 755 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph details the entire scientific thought of an influential natural philosopher whose contributions, unfortunately, have become obscured by the pages of history. Readers will discover an important thinker: Burchard de Volder. He was instrumental in founding the first experimental cabinet at a European University in 1675. The author goes beyond the familiar image of De Volder as a forerunner of Newtonianism in Continental Europe. He consults neglected materials, including handwritten sources, and takes into account new historiographical categories. His investigation maps the thought of an author who did not sit with an univocal philosophical school, but critically dealt with all the ‘major’ philosophers and scientists of his age: from Descartes to Newton, via Spinoza, Boyle, Huygens, Bernoulli, and Leibniz. It explores the way De Volder’s un-systematic thought used, rejected, and re-shaped their theories and approaches. In addition, the title includes transcriptions of De Volder's teaching materials: disputations, dictations, and notes. Insightful analysis combined with a trove of primary source material will help readers gain a new perspective on a thinker so far mostly ignored by scholars. They will find a thoughtful figure who engaged with early modern science and developed a place that fostered experimental philosophy.
Download or read book Tartaglia s Science of Weights and Mechanics in the Sixteenth Century written by Raffaele Pisano and published by Springer. This book was released on 2015-08-25 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a historical and scientific analysis as historical epistemology of the science of weights and mechanics in the sixteenth century, particularly as developed by Tartaglia in his Quesiti et inventioni diverse, Book VII and Book VIII (1546; 1554). In the early 16th century mechanics was concerned mainly with what is now called statics and was referred to as the Scientia de ponderibus, generally pursued by two very different approaches. The first was usually referred to as Aristotelian, where the equilibrium of bodies was set as a balance of opposite tendencies to motion. The second, usually referred to as Archimedean, identified statics with centrobarica, the theory of centres of gravity based on symmetry considerations. In between the two traditions the Italian scholar Niccolò Fontana, better known as Tartaglia (1500?–1557), wrote the treatise Quesiti et inventioni diverse (1546). This volume consists of three main parts. In the first, a historical excursus regarding Tartaglia’s lifetime, his scientific production and the Scientia de ponderibus in the Arabic-Islamic culture, and from the Middle Ages to the Renaissance, is presented. Secondly, all the propositions of Books VII and VIII, by relating them with the Problemata mechanica by the Aristotelian school and Iordani opvsculvm de ponderositate by Jordanus de Nemore are examined within the history and historical epistemology of science. The last part is relative to the original texts and critical transcriptions into Italian and Latin and an English translation. This work gathers and re-evaluates the current thinking on this subject. It brings together contributions from two distinguished experts in the history and historical epistemology of science, within the fields of physics, mathematics and engineering. It also gives much-needed insight into the subject from historical and scientific points of view. The volume composition makes for absorbing reading for historians, epistemologists, philosophers and scientists.

Download or read book Essays in the History of Mechanics written by C. Truesdell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume collects my shorter articles on the history of mechanics, some already published in various places, some revised from earlier papers, and some never published before. All of them began as lectures, and here they are printed as such, little changed from the last times I read them out to an audience. While the several articles concern different aspects of mechanics, overlap and even some repetition could not be avoided, since mechanics is one great science, and the same original oftentimes served more than one end in its growth. My three major historical treatises, which were published in Volumes (II) 11 , 2 12, and 13 of L. Euleri Opera Omnia, are not included. To simplify the printing I have also mostly omitted detailed reference to sources discussed more fully in those treatises, but of course I have added to the texts of the lectures citations of other sources, some notes in answer to questions a reader might ask, and biblio graphical notes at the end of each. I am grateful to the U.S. National Science Foundation for its support of this work through a grant to The Johns Hopkins University.
Download or read book A Cultural History of Work in the Medieval Age written by Valerie L. Garver and published by Bloomsbury Publishing. This book was released on 2020-09-17 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the 2020 PROSE Award for Multivolume Reference/Humanities Work was central to medieval life. Religious and secular authorities generally expected almost everyone to work. Artistic and literary depictions underlined work's cultural value. The vast majority of medieval people engaged in agriculture because it was the only way they could obtain food. Yet their work led to innovations in technology and production and allowed others to engage in specialized labor, helping to drive the growth of cities. Many workers moved to seek employment and to improve their living conditions. For those who could not work, charity was often available, and many individuals and institutions provided forms of social welfare. Guilds protected their members and created means for the transmission of skills. When they were not at work, medieval Christians were to meet their religious obligations yet many also enjoyed various pastimes. A consideration of medieval work is therefore one of medieval society in all its creativity and complexity and that is precisely what this volume provides. A Cultural History of Work in the Medieval Age presents an overview of the period with essays on economies, representations of work, workplaces, work cultures, technology, mobility, society, politics and leisure.
Download or read book A Cultural History of Physics written by Károly Simonyi and published by CRC Press. This book was released on 2012-01-25 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the physical sciences are a continuously evolving source of technology and of understanding about our world, they have become so specialized and rely on so much prerequisite knowledge that for many people today the divide between the sciences and the humanities seems even greater than it was when C. P. Snow delivered his famous 1959 lecture, "The Two Cultures." In A Cultural History of Physics, Hungarian scientist and educator Károly Simonyi succeeds in bridging this chasm by describing the experimental methods and theoretical interpretations that created scientific knowledge, from ancient times to the present day, within the cultural environment in which it was formed. Unlike any other work of its kind, Simonyi’s seminal opus explores the interplay of science and the humanities to convey the wonder and excitement of scientific development throughout the ages. These pages contain an abundance of excerpts from original resources, a wide array of clear and straightforward explanations, and an astonishing wealth of insight, revealing the historical progress of science and inviting readers into a dialogue with the great scientific minds that shaped our current understanding of physics. Beautifully illustrated, accurate in its scientific content and broad in its historical and cultural perspective, this book will be a valuable reference for scholars and an inspiration to aspiring scientists and humanists who believe that science is an integral part of our culture.

Download or read book Virtual History Alternatives And Counterfactuals written by Niall Ferguson and published by Basic Books. This book was released on 2008-08-06 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: What if there had been no American War of Independence? What if Hitler had invaded Britain? What if Kennedy had lived? What if Russia had won the Cold War? Niall Ferguson, author of the highly acclaimed The Pity of War, leads the charge in this historically rigorous series of separate voyages into “imaginary time” and provides far-reaching answers to these intriguing questions.Ferguson's brilliant 90-page introduction doubles as a manifesto on the methodology of counter-factual history. His equally masterful afterword traces the likely historical ripples that would have proceeded from the maintenance of Stuart rule in England. This breathtaking narrative gives us a convincing, detailed “alternative history” of the West—from the accession of “James III” in 1701, to a Nazi-occupied England, to a U.S. Prime Minister Kennedy who lives to complete his term.
Download or read book The Laws of the Virtual Worlds written by Greg Lastowka and published by . This book was released on 2017 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: What if you could check out of your world, and enter a place where the social environment was different, where real world laws didn't apply, and where the political system could be anything you wanted it to be? What if you could socialize there with family and friends, build your own palace, go skiing, and even hold down a job there? And what if there wasn't one alternate world, there were hundreds, and what if millions of people checked out of Earth and went there every day?Virtual worlds - online worlds where millions of people come to interact, play, and socialize - are a new type of social order. In this Article, we examine the implications of virtual worlds for our understanding of law, and demonstrate how law affects the interests of those within the world. After providing an extensive primer on virtual worlds, including their history and function, we examine two fundamental issues in detail.First, we focus on property, and ask whether it is possible to say that virtual world users have real world property interests in virtual objects. Adopting economic accounts that demonstrate the real world value of these objects and the exchange mechanisms for trading these objects, we show that, descriptively, these types of objects are indistinguishable from real world property interests. Further, the normative justifications for property interests in the real world apply - sometimes more strongly - in the virtual worlds.Second, we discuss whether avatars have enforceable legal and moral rights. Avatars, the user-controlled entities that interact with virtual worlds, are a persistent extension of their human users, and users identify with them so closely that the human-avatar being can be thought of as a cyborg. We examine the issue of cyborg rights within virtual worlds and whether they may have real world significance.The issues of virtual property and avatar rights constitute legal challenges for our online future. Though virtual worlds may be games now, they are rapidly becoming as significant as real-world places where people interact, shop, sell, and work. As society and law begin to develop within virtual worlds, we need to have a better understanding of the interaction of the laws of the virtual worlds with the law of this world.
Download or read book Virtual Marshall McLuhan written by Donald Theall and published by McGill-Queen's Press - MQUP. This book was released on 2001-01-19 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Donald Theall explores and explains the significance of the emergence of McLuhan as an important figure in North America in the development of an understanding of culture, communication, and technology. He reveals important information about McLuhan and his relationships with his earliest collaborator and life-long friend, anthropologist Edmund Carpenter, as well as with Theall himself, McLuhan's first doctoral student. McLuhan emerges as a complex human being, at once attractive, witty, egotistic, and exasperating. Theall examines McLuhan's many roles - proponent of a poetic method; pop guru adopted by Tom Wolfe, Woody Allen and others; North American precursor of French theory (Baudrillard, Barthes, Derrida, Deleuze); artist; and shaman. Complex and intellectual, neither uncritical adulation nor demonization, The Virtual Marshall McLuhan does justice to a unique figure caught in a struggle between tradition and modernity, between faith and anarchy.
Download or read book A History of Mechanics written by René Dugas and published by Courier Corporation. This book was released on 2012-11-07 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A remarkable work which will remain a document of the first rank for the historian of mechanics." — Louis de Broglie In this masterful synthesis and summation of the science of mechanics, Rene Dugas, a leading scholar and educator at the famed Ecole Polytechnique in Paris, deals with the evolution of the principles of general mechanics chronologically from their earliest roots in antiquity through the Middle Ages to the revolutionary developments in relativistic mechanics, wave and quantum mechanics of the early 20th century. The present volume is divided into five parts: The first treats of the pioneers in the study of mechanics, from its beginnings up to and including the sixteenth century; the second section discusses the formation of classical mechanics, including the tremendously creative and influential work of Galileo, Huygens and Newton. The third part is devoted to the eighteenth century, in which the organization of mechanics finds its climax in the achievements of Euler, d'Alembert and Lagrange. The fourth part is devoted to classical mechanics after Lagrange. In Part Five, the author undertakes the relativistic revolutions in quantum and wave mechanics. Writing with great clarity and sweep of vision, M. Dugas follows closely the ideas of the great innovators and the texts of their writings. The result is an exceptionally accurate and objective account, especially thorough in its accounts of mechanics in antiquity and the Middle Ages, and the important contributions of Jordanus of Nemore, Jean Buridan, Albert of Saxony, Nicole Oresme, Leonardo da Vinci, and many other key figures. Erudite, comprehensive, replete with penetrating insights, AHistory of Mechanics is an unusually skillful and wide-ranging study that belongs in the library of anyone interested in the history of science.
