Download or read book Douglas Rayner Hartree written by Charlotte Froese Fischer and published by World Scientific. This book was released on 2003 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This scientific biography of Douglas R Hartree not only describes important events in his life but also outlines his contributions to a number of fields. He is best known for his OC self-consistent fieldOCO theory for atoms, a theory he later used for the much more difficult problem of predicting the behavior of a magnetron. When Fock pre-empted his work on exchange, he began research into radio-wave propagation. Hartree was very interested in the process of computation. When he learned of a differential analyzer for solving differential equations, he first built a model using Meccano, a toy for children. The success of this model spread the notion of using devices to solve scientific problems. Application of the analyzer led Hartree to control theory and fluid dynamics. In both these areas he made significant, original contributions. With his extensive computing background, he was selected as the first civilian to evaluate the possibility of applying the US ENIAC computer to nonmilitary problems. His research touched the lives of many scientists."

Download or read book The Analogue Alternative written by James S. Small and published by Routledge. This book was released on 2013-06-17 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are in the midst of a digital revolution - until recently, the majority of appliances used in everyday life have been developed with analogue technology. Now, either at home or out and about, we are surrounded by digital technology such as digital 'film', audio systems, computers and telephones. From the late 1940s until the 1970s, analogue technology was a genuine alternative to digital, and the two competing technologies ran parallel with each other. During this period, a community of engineers, scientists, academics and businessmen continued to develop and promote the analogue computer. At the height of the Cold War, this community and its technology met with considerable success in meeting the urgent demand for high speed computing for use in the design and simulation of rockets, aircraft and manned space vehicles. The Analogue Alternative tracks the development, commercialisation and ultimate decline of the electronic analogue computer in the USA and Britain. It examines the roles played by technical, economic and cultural factors in the competition between the alternative technologies, but more importantly, James Small demonstrates that non-technical factors, such as the role of 'military enterprise' and the working practices of analogue engineers, have been the most crucial in analogue's demise.^l This book will be of interest to students of the history and sociology of science and technology, particularly computing. It will also be relevant to those interested in technical change and innovation, and the study of scientific cultures.

Download or read book Elsevier s Dictionary of Chemoetymology written by Alexander Senning and published by Elsevier. This book was released on 2006-10-30 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Noting a marked lack of comprehensiveness and/or contemporaneity among typical reference works on chemical etymology, as well as a somewhat spotty coverage of chemical terms and their etymology in comprehensive dictionaries and textbooks the author decided to write an up-to-date desk reference on chemical etymology which would satisfy the needs of casual readers as well as those of more demanding users of etymological lore. Characteristic user-friendly features of the present work include avoidance of cumbersome abbreviations, avoidance of entries in foreign alphabets, and a broad coverage of all chemical disciplines including mineralogy. Biological, medical, geological, physical and mathematical terms are only considered where they appear of interest to mainstream chemists.This book does not provide definitions of terms (unless required in the etymological context) nor guidance as to the timeliness of different nomenclature systems. The typical user will from the outset be well aware of the exact meaning of the terms he or she focuses on and only require the etymological background to be used. Examples of sources which have been drawn upon in the preparation of this book, apart from the extremely useful Internet resource Google, are listed, but an exhausting enumeration would be tiresome and impractical..* an up-to-date desk reference on chemical etymology* characteristic user-friendly features* broad coverage of all chemical disciplines

Download or read book Celebrating 100 Years of Female Fellowship of the Geological Society Discovering Forgotten Histories written by C.V. Burek and published by Geological Society of London. This book was released on 2021-03-18 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Geological Society of London was founded in 1807. At the time, membership was restricted to men, many of whom became well-known names in the history of the geological sciences. On the 21 May 1919, the first female Fellows were elected to the Society, 112 years after its formation. This Special Publication celebrates the centenary of that important event. In doing so it presents the often untold stories of pioneering women geoscientists from across the world who navigated male-dominated academia and learned societies, experienced the harsh realities of Siberian field-exploration, or responded to the strategic necessity of the ‘petroleum girls’ in early American oil exploration and production. It uncovers important female role models in the history of science, and investigates why not all of these women received due recognition from their contemporaries and peers. The work has identified a number of common issues that sometimes led to original work and personal achievements being lost or unacknowledged, and as a consequence, to histories being unwritten.

This book was released on 2012-01-13 with total page 687 pages. Available in PDF, EPUB and Kindle. Book excerpt: Practical Aspects of Computational Chemistry I: An Overview of the Last Two Decades and Current Trends gathers the advances made within the last 20 years by well-known experts in the area of theoretical and computational chemistry and physics. The title itself reflects the celebration of the twentieth anniversary of the “Conference on Current Trends in Computational Chemistry (CCTCC)” to which all authors have participated and contributed to its success. This volume poses (and answers) important questions of interest to the computational chemistry community and beyond. What is the historical background of the “Structural Chemistry”? Is there any way to avoid the problem of intruder state in the multi-reference formulation? What is the recent progress on multi-reference coupled cluster theory? Starting with a historical account of structural chemistry, the book focuses on the recent advances made in promising theories such as many body Brillouin-Wigner theory, multireference state-specific coupled cluster theory, relativistic effect in chemistry, linear and nonlinear optical properties of molecules, solution to Kohn-Sham problem, electronic structure of solid state materials, development of model core potential, quantum Monte Carlo method, nano and molecular electronics, dynamics of photodimerization and excited states, intermolecular interactions, hydrogen bonding and non-hydrogen bonding interactions, conformational flexibility, metal cations in zeolite catalyst and interaction of nucleic acid bases with minerals. Practical Aspects of Computational Chemistry I: An Overview of the Last Two Decades and Current Trends is aimed at theoretical and computational chemists, physical chemists, materials scientists, and particularly those who are eager to apply computational chemistry methods to problem of chemical and physical importance. This book will provide valuable information to undergraduate, graduate, and PhD students as well as to established researchers.

Download or read book Neither Physics nor Chemistry written by Kostas Gavroglu and published by MIT Press. This book was released on 2011-10-07 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of a discipline at the intersection of physics, chemistry, and mathematics. Quantum chemistry—a discipline that is not quite physics, not quite chemistry, and not quite applied mathematics—emerged as a field of study in the 1920s. It was referred to by such terms as mathematical chemistry, subatomic theoretical chemistry, molecular quantum mechanics, and chemical physics until the community agreed on the designation of quantum chemistry. In Neither Physics Nor Chemistry, Kostas Gavroglu and Ana Simões examine the evolution of quantum chemistry into an autonomous discipline, tracing its development from the publication of early papers in the 1920s to the dramatic changes brought about by the use of computers in the 1970s. The authors focus on the culture that emerged from the creative synthesis of the various traditions of chemistry, physics, and mathematics. They examine the concepts, practices, languages, and institutions of this new culture as well as the people who established it, from such pioneers as Walter Heitler and Fritz London, Linus Pauling, and Robert Sanderson Mulliken, to later figures including Charles Alfred Coulson, Raymond Daudel, and Per-Olov Löwdin. Throughout, the authors emphasize six themes: epistemic aspects and the dilemmas caused by multiple approaches; social issues, including academic politics, the impact of textbooks, and the forging of alliances; the contingencies that arose at every stage of the developments in quantum chemistry; the changes in the field when computers were available to perform the extraordinarily cumbersome calculations required; issues in the philosophy of science; and different styles of reasoning.
