Book Description
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 “self-consistent field” 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.

Book Description
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.

Book Description
A bicentennial celebration of brilliant thinkers from The University of Manchester's history. The year 2024 marks two centuries since the establishment of The University of Manchester in its earliest form. The first of England’s civic universities, Manchester has been home and host to a huge number of influential thinkers and generated world-changing ideas. This book presents a rich account of the remarkable contribution that people associated with The University of Manchester have made to human knowledge. A who’s who of Manchester greats, it presents fascinating snapshots of pioneering artists, scholars and scientists, from the poet and activist Eva Gore-Booth to the economist Arthur Lewis, the computer scientist Alan Turing and the physicist Brian Cox.

Book Description
Changes in the present challenge us to reinterpret the past, but historians have not yet come to grips with the convergence of computing, media, and communications technology. Today these things are inextricably intertwined, in technologies such as the smartphone and internet, in convergent industries, and in social practices. Yet they remain three distinct historical subfields, tilled by different groups of scholars using different tools. We often call this conglomeration “the digital,” recognizing its deep connection to the technology of digital computing. Unfortunately, interdisciplinary studies of digital practices, digital methods, or digital humanities have rarely been informed by deep engagement with the history of computing.Contributors to this volume have come together to reexamine an apparently familiar era in the history of computing through new lenses, exploring early digital computing and engineering practice as digital phenomena rather than as engines of mathematics and logic. Most focus on the period 1945 to 1960, the era in which the first electronic digital computers were created and the computer industry began to develop. Because digitality is first and foremost a way of reading objects and encoding information within them, we are foregrounding topics that have until now been viewed as peripheral in the history of computing: betting odds calculators, card file systems, program and data storage, programmable calculators, and digital circuit design practices. Reconceptualizing the “history of computing” as study of the “early digital” decenters the stored program computer, repositioning it as one of many digital technologies.

Book Description
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.

Book Description
Das Buch widmet sich AN/FSQ-7, einem der aussergewöhnlichsten und einflussreichsten Digitalrechner aller Zeiten, über den erst in den letzten Jahren (aufgrund von Geheimhaltungsvorschriften) detaillierte Informationen zugänglich wurden. Über einen Zeitraum von über 30 Jahren wurden in den USA 23 Rechenzentren auf Basis von jeweils zwei AN/FSQ-7 betrieben, die das Herz von SAGE, dem Semi Automatic Ground Environment bildeten, das für die Luftraumüberwachung der USA und (in Teilen) Kanada zuständig war.
