The Gaussian Approximation Potential

by Albert Bartók-Pártay

Simulation of materials at the atomistic level is an important tool in studying microscopic structures and processes. The atomic interactions necessary for the simulations are correctly described by Quantum Mechanics, but the size of systems and the length of processes that can be modelled are still limited. The framework of Gaussian Approximation Potentials that is developed in this thesis allows us to generate interatomic potentials automatically, based on quantum mechanical data. The resulting potentials offer several orders of magnitude faster computations, while maintaining quantum mechanical accuracy. The method has already been successfully applied for semiconductors and metals.

The Gender Knot: Unraveling Our Patriarchal Legacy; Third Edition

by Allan G. Johnson

New Third Edition! The Gender Knot, Allan Johnson's response to the pain and confusion that men and women experience by living with gender inequality, explains what patriarchy is and isn't, how it works, and what gets in the way of understanding and doing something about it. Johnson's simple yet powerful approach avoids the paralyzing trap of guilt, blame, anger, and defensive denial that often results from conversations about gender. This edition features: • Updated references, data, resources, and examples, especially in relation to issues of sexual orientation and gender identity (e.g., gay marriage, transgender/cisgender) • A glossary of terms • A new chapter, "What Changes and What Does Not: Manhood and Violence," that provides an extended analysis of the causes of men's violence as a patriarchal phenomenon

The Gene Machine: How Genetic Technologies Are Changing the Way We Have Kids—and the Kids We Have

by Bonnie Rochman

A sharp-eyed exploration of the promise and peril of having children in an age of genetic tests and interventionsIs screening for disease in an embryo a humane form of family planning or a slippery slope toward eugenics? Should doctors tell you that your infant daughter is genetically predisposed to breast cancer? If tests revealed that your toddler has a genetic mutation whose significance isn’t clear, would you want to know?In The Gene Machine, the award-winning journalist Bonnie Rochman deftly explores these hot-button questions, guiding us through the new frontier of gene technology and how it is transforming medicine, bioethics, health care, and the factors that shape a family. Rochman tells the stories of scientists working to unlock the secrets of the human genome; genetic counselors and spiritual advisers guiding mothers and fathers through life-changing choices; and, of course, parents (including Rochman herself) grappling with revelations that are sometimes joyous, sometimes heartbreaking, but always profound. She navigates the dizzying and constantly expanding array of prenatal and postnatal tests, from carrier screening to genome sequencing, while considering how access to more tests is altering perceptions of disability and changing the conversation about what sort of life is worth living and who draws the line. Along the way, she highlights the most urgent ethical quandary: Is this technology a triumph of modern medicine or a Pandora’s box of possibilities?Propelled by human narratives and meticulously reported, The Gene Machine is both a scientific road map and a meditation on our power to shape the future. It is a book that gets to the very core of what it means to be human.

The Gene, the Clinic, and the Family: Diagnosing Dysmorphology, Reviving Medical Dominance (Genetics and Society)

by Joanna Latimer

While some theorists argue that medicine is caught in a relentless process of ‘geneticization’ and others offer a thesis of biomedicalization, there is still little research that explores how these effects are accomplished in practice. Joanna Latimer, whose groundbreaking ethnography on acute medicine gave us the social science classic The Conduct of Care, moves her focus from the bedside to the clinic in this in-depth study of genetic medicine. Against current thinking that proselytises the rise of laboratory science, Professor Latimer shows how the genetic clinic is at the heart of the revolution in the new genetics. Tracing how work on the abnormal in an embryonic genetic science, dysmorphology, is changing our thinking about the normal, The Gene, the Clinic, and the Family charts new understandings about family, procreation and choice. Far from medicine experiencing the much-proclaimed ‘death of the clinic’, this book shows how medicine is both reasserting its status as a science and revitalising its dominance over society, not only for now but for societies in the future. This book will appeal to students, scholars and professionals interested in medical sociology, science and technology studies, the anthropology of science, medical science and genetics, as well as genetic counselling.

The Gene: From Genetics to Postgenomics

by Hans-Jörg Rheinberger Staffan Müller-Wille Adam Bostanci

Few concepts played a more important role in twentieth-century life sciences than that of the gene. Yet at this moment, the field of genetics is undergoing radical conceptual transformation, and some scientists are questioning the very usefulness of the concept of the gene, arguing instead for more systemic perspectives. The time could not be better, therefore, for Hans-Jörg Rheinberger and Staffan Müller-Wille's magisterial history of the concept of the gene. Though the gene has long been the central organizing theme of biology, both conceptually and as an object of study, Rheinberger and Müller-Wille conclude that we have never even had a universally accepted, stable definition of it. Rather, the concept has been in continual flux—a state that, they contend, is typical of historically important and productive scientific concepts. It is that very openness to change and manipulation, the authors argue, that made it so useful: its very mutability enabled it to be useful while the technologies and approaches used to study and theorize about it changed dramatically.

The Genealogical Science: The Search for Jewish Origins and the Politics of Epistemology

by Abu El-Haj Nadia

The Genealogical Science analyzes the scientific work and social implications of the flourishing field of genetic history. A biological discipline that relies on genetic data in order to reconstruct the geographic origins of contemporary populations--their histories of migration and genealogical connections to other present-day groups--this historical science is garnering ever more credibility and social reach, in large part due to a growing industry in ancestry testing. In this book, Nadia Abu El-Haj examines genetic history's working assumptions about culture and nature, identity and biology, and the individual and the collective. Through the example of the study of Jewish origins, she explores novel cultural and political practices that are emerging as genetic history's claims and "facts" circulate in the public domain and illustrates how this historical science is intrinsically entangled with cultural imaginations and political commitments. Chronicling late-nineteenth- to mid-twentieth-century understandings of race, nature, and culture, she identifies continuities and shifts in scientific claims, institutional contexts, and political worlds in order to show how the meanings of biological difference have changed over time. In so doing she gives an account of how and why it is that genetic history is so socially felicitous today and elucidates the range of understandings of the self, individual and collective, this scientific field is making possible. More specifically, through her focus on the history of projects of Jewish self-fashioning that have taken place on the terrain of the biological sciences, The Genealogical Science analyzes genetic history as the latest iteration of a cultural and political practice now over a century old.

The General Kelvin-Helmholtz Stability Model: With Applications to Sand Wave and Water Wave Generation

by Hermann Moshagen

This book presents a generalized version of the classical Kelvin-Helmholtz instability, a useful tool which allows for new approaches when studying stability problems in fluid mechanics, as well as its important applications. It begins by providing an introduction to hydrodynamic stability and the Kelvin-Helmholtz (KH) instability. The author then develops the general KH stability model for a multi-layer flow system, which includes the conventional KH instability as a special case. This book also includes the detailed discussion of two important applications of this model: the generation of sand waves in alluvial channels and the generation of wind waves on water. Additionally, the effects of nonlinearities and the use of computational methods to study KH instability are included. This book serves as a concise and modern treatment of the KH stability model with specific attention paid to hydrodynamic stability analysis. It is ideal for graduate students interested in fluid dynamics as well as scientists and engineers in the fields of oceanography, geophysics, offshore engineering, and more.

The General Principles of Quantum Theory (Routledge Library Editions: 20th Century Science)

by George Temple

Published in 1934, this monograph was one of the first introductory accounts of the principles which form the physical basis of the Quantum Theory, considered as a branch of mathematics. The exposition is restricted to a discussion of general principles and does not attempt detailed application to the wide domain of atomic physics, although a number of special problems are considered in elucidation of the principles. The necessary fundamental mathematical methods – the theory of linear operators and of matrics – are developed in the first chapter so this could introduce anyone to the new theory. This is an interesting snapshot of scientific history.

The General and the Genius: Groves and Oppenheimer ? The Unlikely Partnership that Built the Atom Bomb

by James Kunetka

Two ambitious men. One historic mission. With a blinding flash in the New Mexico desert in the summer of 1945, the world was changed forever. The bomb that ushered in the atomic age was the product of one of history's most improbable partnerships. The General and the Genius reveals how two extraordinary men pulled off the greatest scientific feat of the twentieth century. Leslie Richard Groves of the Army Corps of Engineers, who had made his name by building the Pentagon in record time and under budget, was made overlord of the impossibly vast scientific enterprise known as the Manhattan Project. His mission: to beat the Nazis to the atomic bomb. So he turned to the nation's preeminent theoretical physicist, J. Robert Oppenheimer--the chain-smoking, martini-quaffing son of wealthy Jewish immigrants, whose background was riddled with communist associations--Groves's opposite in nearly every respect. In their three-year collaboration, the iron-willed general and the visionary scientist led a brilliant team in a secret mountaintop lab and built the fearsome weapons that ended the war but introduced the human race to unimaginable new terrors. And at the heart of this most momentous work of World War II is the story of two extraordinary men--the general and the genius.

The Generalized Fourier Series Method: Bending of Elastic Plates (Developments in Mathematics #65)

by Christian Constanda Dale Doty

This book explains in detail the generalized Fourier series technique for the approximate solution of a mathematical model governed by a linear elliptic partial differential equation or system with constant coefficients. The power, sophistication, and adaptability of the method are illustrated in application to the theory of plates with transverse shear deformation, chosen because of its complexity and special features. In a clear and accessible style, the authors show how the building blocks of the method are developed, and comment on the advantages of this procedure over other numerical approaches. An extensive discussion of the computational algorithms is presented, which encompasses their structure, operation, and accuracy in relation to several appropriately selected examples of classical boundary value problems in both finite and infinite domains. The systematic description of the technique, complemented by explanations of the use of the underlying software, will help the readers create their own codes to find approximate solutions to other similar models. The work is aimed at a diverse readership, including advanced undergraduates, graduate students, general scientific researchers, and engineers.The book strikes a good balance between the theoretical results and the use of appropriate numerical applications. The first chapter gives a detailed presentation of the differential equations of the mathematical model, and of the associated boundary value problems with Dirichlet, Neumann, and Robin conditions. The second chapter presents the fundamentals of generalized Fourier series, and some appropriate techniques for orthonormalizing a complete set of functions in a Hilbert space. Each of the remaining six chapters deals with one of the combinations of domain-type (interior or exterior) and nature of the prescribed conditions on the boundary. The appendices are designed to give insight into some of the computational issues that arise from the use of the numerical methods described in the book.Readers may also want to reference the authors’ other books Mathematical Methods for Elastic Plates, ISBN: 978-1-4471-6433-3 and Boundary Integral Equation Methods and Numerical Solutions: Thin Plates on an Elastic Foundation, ISBN: 978-3-319-26307-6.

The Generalized Multipole Technique for Light Scattering: Recent Developments (Springer Series on Atomic, Optical, and Plasma Physics #99)

by Thomas Wriedt Yuri Eremin

This book presents the Generalized Multipole Technique as a fast and powerful theoretical and computation tool to simulate light scattering by nonspherical particles. It also demonstrates the considerable potential of the method. In recent years, the concept has been applied in new fields, such as simulation of electron energy loss spectroscopy and has been used to extend other methods, like the null-field method, making it more widely applicable. The authors discuss particular implementations of the GMT methods, such as the Discrete Sources Method (DSM), Multiple Multipole Program (MMP), the Method of Auxiliary Sources (MAS), the Filamentary Current Method (FCM), the Method of Fictitious Sources (MFS) and the Null-Field Method with Discrete Sources (NFM-DS). The Generalized Multipole Technique is a surface-based method to find the solution of a boundary-value problem for a given differential equation by expanding the fields in terms of fundamental or other singular solutions of this equation. The amplitudes of these fundamental solutions are determined from the boundary condition at the particle surface. Electromagnetic and light scattering by particles or systems of particles has been the subject of intense research in various scientific and engineering fields, including astronomy, optics, meteorology, remote sensing, optical particle sizing and electromagnetics, which has led to the development of a large number of modelling methods based on the Generalized Multipole Technique for quantitative evaluation of electromagnetic scattering by particles of various shapes and compositions. The book describes these methods in detail.

The Genesis Enigma

by Andrew Parker

Does modern science - while agreeing with Darwinian evolution, the big bang theory and the complexity and deep age of the universe - prove the order of creation as described in the Bible to be true? It takes just one page in the Bible to describe the creation of the universe, the Earth, the sky, the seas and all life on the planet. But a close reading will reveal that it is written in a very odd order. Light is mentioned twice - in 'let there be light' and secondly in 'let there be lights . . . to divide the day from night'. Whales appear before birds. Vegetation appears after 'let there be light' but before day is separated from night. In The Genesis Enigma Andrew Parker argues that the reason the Genesis account is strangely ordered is, amazingly, that it precisely reflects the order of events as we now understand them. The latest reinterpretation of Earth's ancient rocks and fossils and their comparisons with animals today has completed our understanding of the history of the Earth and of life. By comparing the data of science with the words and phrases of Genesis 1-11 the remarkable parallels become clear. In a fascinating and controversial scientific detective story Andrew Parker reveals how the latest modern understanding corresponds in unerring detail with the creation account in Genesis. His astonishing conclusions will revolutionise how many of us view the debate between science and religion, and asks the question: in a scientific world is there still a place for God?

The Genesis Machine: Our Quest to Rewrite Life in the Age of Synthetic Biology

by Amy Webb Andrew Hessel

Named one of The New Yorker's BEST BOOKS OF 2022 SO FARThe next frontier in technology is inside our own bodies. Synthetic biology will revolutionize how we define family, how we identify disease and treat aging, where we make our homes, and how we nourish ourselves. This fast-growing field—which uses computers to modify or rewrite genetic code—has created revolutionary, groundbreaking solutions such as the mRNA COVID vaccines, IVF, and lab-grown hamburger that tastes like the real thing. It gives us options to deal with existential threats: climate change, food insecurity, and access to fuel. But there are significant risks. Who should decide how to engineer living organisms? Whether engineered organisms should be planted, farmed, and released into the wild? Should there be limits to human enhancements? What cyber-biological risks are looming? Could a future biological war, using engineered organisms, cause a mass extinction event? Amy Webb and Andrew Hessel&’s riveting examination of synthetic biology and the bioeconomy provide the background for thinking through the upcoming risks and moral dilemmas posed by redesigning life, as well as the vast opportunities waiting for us on the horizon.

The Genesis of Feynman Diagrams

by Adrian Wüthrich

In a detailed reconstruction of the genesis of Feynman diagrams the author reveals that their development was constantly driven by the attempt to resolve fundamental problems concerning the uninterpretable infinities that arose in quantum as well as classical theories of electrodynamic phenomena. Accordingly, as a comparison with the graphical representations that were in use before Feynman diagrams shows, the resulting theory of quantum electrodynamics, featuring Feynman diagrams, differed significantly from earlier versions of the theory in the way in which the relevant phenomena were conceptualized and modelled. The author traces the development of Feynman diagrams from Feynman's "struggle with the Dirac equation" in unpublished manuscripts to the two of Freeman Dyson's publications which put Feynman diagrams into a field theoretic context. The author brings to the fore that Feynman and Dyson not only created a powerful computational device but, above all, a new conceptual framework in which the uninterpretable infinities that had arisen in the old form of the theory could be precisely identified and subsequently removed in a justifiable manner.
