An Introduction to Astronomy and Astrophysics
Par Pankaj Jain. 2024
Astronomy is the field of science devoted to the study of astronomical objects, such as stars, galaxies, and nebulae. Astronomers…
have gathered a wealth of knowledge about the universe through hundreds of years of painstaking observations. These observations are interpreted by the use of physical and chemical laws familiar to mankind. These interpretations supply information about the nature of these astronomical objects, allowing for the deduction of their surface and interior conditions. The science associated with these interpretations is called astrophysics.An Introduction to Astronomy and Astrophysics offers a comprehensive introduction to astronomy and astrophysics, complete with illustrative examples and illuminating homework problems. Requiring a familiarity with basic physics and mathematics, this undergraduate-level textbook: Addresses key physics concepts relevant to stellar observations, including radiation, electromagnetic spectrum, photometry, continuous and discrete spectrum, and spectral lines. Describes instruments used for astronomical observations as well as how the radiation received is characterized and interpreted to determine the properties of stars. Examines the structure of stars, the basic equations that explain stars in equilibrium, and the fusion reactions occurring in stellar cores. Discusses the evolution of stars, the solar system, the dynamics of galaxies, and the fundamentals of modern cosmology. Explores the universe at high redshifts, where it is dominated by objects such as active galaxies. An Introduction to Astronomy and Astrophysics teaches students how to interpret the night sky, providing them with a critical understanding of the stars and sun, solar system, extrasolar planets, stars, and galaxies.The book is thoroughly revised to make it an essential textbook for students. The Second edition introduces the following changes: New solutions are provided at the end of all the chapters. The number of problems has increased. Major chapters have been considerably revised and new developments in this field have been introduced.Computational Physics: Fortran Version
Par Steven E. Koonin. 2018
Computational Physics is designed to provide direct experience in the computer modeling of physical systems. Its scope includes the essential…
numerical techniques needed to "do physics" on a computer. Each of these is developed heuristically in the text, with the aid of simple mathematical illustrations. However, the real value of the book is in the eight Examples and Projects, where the reader is guided in applying these techniques to substantial problems in classical, quantum, or statistical mechanics. These problems have been chosen to enrich the standard physics curriculum at the advanced undergraduate or beginning graduate level. The book will also be useful to physicists, engineers, and chemists interested in computer modeling and numerical techniques. Although the user-friendly and fully documented programs are written in FORTRAN, a casual familiarity with any other high-level language, such as BASIC, PASCAL, or C, is sufficient. The codes in BASIC and FORTRAN are available on the web at http://www.computationalphysics.info. They are available in zip format, which can be expanded on UNIX, Window, and Mac systems with the proper software. The codes are suitable for use (with minor changes) on any machine with a FORTRAN-77 compatible compiler or BASIC compiler. The FORTRAN graphics codes are available as well. However, as they were originally written to run on the VAX, major modifications must be made to make them run on other machines.Profiles in Mental Health Courage

mental health. This book offers deeply compelling stories about the bravery and resilience of those living with a variety of mental illnesses and addictions. Several years ago, Patrick J. Kennedy shared the story of his personal and family challenges with mental illness and addiction—and the nation&’s—in his bestselling memoir, A Common Struggle. Now, he and his Common Struggle coauthor, award-winning healthcare journalist Stephen Fried, have crafted this powerful new book sharing the untold stories of others—a special group who agreed to talk about their illnesses, treatments, and struggles for the first time. When Kennedy&’s uncle, President John F. Kennedy, published his classic book Profiles in Courage, he hoped to inspire &“political courage&” by telling the stories of brave U.S. senators who changed America. In Profiles in Mental Health Courage, former Congressman Kennedy adapts his uncle&’s idea to inspire the &“mental health courage&” it takes for those with these conditions to treat their illnesses, and risk telling their stories to help America face its crisis in our families, our workplaces, our jails, and on our streets. The resounding silence surrounding these illnesses remains persistent, and this book takes an unflinching look at the experience of mental illness and addiction that inspires profound connection, empathy, and action. In this book, you&’ll meet people of all ages, backgrounds, and futures, across politics and government, Hollywood and the arts, tech and business, sports and science—some recovering, some relapsing, some just barely holding on, but all sharing experiences and insights we need to better understand. You&’ll also meet those trying to help them through—parents, siblings, spouses, therapists, bosses, doctors, and friends who create the extended families needed to support care and wellness. The personal stories they share with Kennedy and Fried are intimate, sometimes shocking, always revealing. And they are essential reading for caregivers, family members, policymakers, and the general public—just as they are for those who often feel alone in experiencing these challenges themselves.Heart of Darkness: Unraveling the Mysteries of the Invisible Universe (Princeton Science Library #148)
Par Jeremiah P. Ostriker, Simon Mitton. 2013
Humanity's ongoing quest to unlock the secrets of dark matter and dark energyHeart of Darkness describes the incredible saga of…
humankind's quest to unravel the deepest secrets of the universe. Over the past forty years, scientists have learned that two little-understood components—dark matter and dark energy—comprise most of the known cosmos, explain the growth of all cosmic structure, and hold the key to the universe's fate. The story of how evidence for the so-called "Lambda-Cold Dark Matter" model of cosmology has been gathered by generations of scientists throughout the world is told here by one of the pioneers of the field, Jeremiah Ostriker, and his coauthor Simon Mitton.From humankind's early attempts to comprehend Earth's place in the solar system, to astronomers' exploration of the Milky Way galaxy and the realm of the nebulae beyond, to the detection of the primordial fluctuations of energy from which all subsequent structure developed, this book explains the physics and the history of how the current model of our universe arose and has passed every test hurled at it by the skeptics. Throughout this rich story, an essential theme is emphasized: how three aspects of rational inquiry—the application of direct measurement and observation, the introduction of mathematical modeling, and the requirement that hypotheses should be testable and verifiable—guide scientific progress and underpin our modern cosmological paradigm.This monumental puzzle is far from complete, however, as scientists confront the mysteries of the ultimate causes of cosmic structure formation and the real nature and origin of dark matter and dark energy.The de Sitter: An Introduction to Elementary Systems and Modeling the Dark Energy Universe (Synthesis Lectures on Mathematics & Statistics)

(dS) group representations. Building on the success of the first edition, the book offers a more in-depth analysis of mathematical aspects, conceptual foundations, and practical implications related to the dS group, including its Lie manifold, Lie algebra, and co-adjoint orbits, viewing the latter as potential classical elementary systems within the context of dS spacetime. Additionally, the examination of unitary irreducible representations (UIRs) sheds light on the potential existence of quantum elementary systems within the dS spacetime framework. The authors emphasize consistency with Wigner's approach to elementary systems, incorporate Wigner's principles and exploring projective UIRs of the dS group, and provide a deeper insight into the nature of dS elementary systems. Particular attention is paid to: the “smooth” transition from classical to quantum theory, the physical content under vanishing curvature, and the thermal interpretation from a quantum perspective. The book also focuses on the physical interpretation of elementary systems in curved spacetimes, recognizing the limitations of traditional concepts derived from flat Minkowski spacetime and the Poincaré group.Digital Resilience: Navigating Disruption and Safeguarding Data Privacy (EAI/Springer Innovations in Communication and Computing)

how it affects well drilling. Prediction of carbonate pore pressure is difficult; therefore, a new set of pore pressure equations for carbonates were developed, accounting for overpressure and depleted conditions. A detailed description of a fully coupled model is shown in order to discuss geomechanics and the coupling of fluid flow in porous media and to achieve a better representation of the mechanics involved in the exploitation of NFRs. Additionally, results of a new model of geomechanics in vuggy carbonate reservoirs are presented. This book also displays a wide discussion, analysis, and numerical implementation of six different salt rheology models. Furthermore, the most representative rheology salt models were studied aside with the fully coupled model of geomechanics and fluid flow in porous media. Finally, it presents an answer to areal case of a well drilled near a salt diapir where anomalous pore pressure was found.Computational Fluid Dynamics: Finite Difference Method and Lattice Boltzmann Method (Engineering Applications of Computational Methods #20)

applications in fluid dynamics. Furthermore, some new ideas are presented in this book, for example, a method to solve the transition matrix by difference operator transformation. For this method, the book gives the definition of Fourier integral transformation of translation operator, and proves the transition matrix equaling to the differential operator transformation, so that it is extended to general situations of explicit, implicit, multi-layer difference equations, etc. This flexible approach is also used in the differential part. In addition, the book also includes six types of equivalent stability definitions in two ways and deeply analyzes their errors, stabilities and convergences of the difference equations. What is more important, some new scientific contributions on lattice Boltzmann method (LBM) in recent years are presented in the book as well. The authors write the book combining their ten years teaching experience and research results and this book is intended for graduate students who are interested in the area of computational fluid dynamics (CFD). Authors list some new research achievements, such as simplified lattice Boltzmann method, the simplified lattice Boltzmann flux solver and discrete unified gas kinetic scheme, and expect that this new information could give readers possible further investigating ideas in their future research on CFD area.AQA A Level Physics Student Book 1

Par Gerald Friesen. 2024
The life and times of the Premier from Red River John Norquay, orphan and prodigy, was a leader among the…
Scots Cree peoples of western Canada. Born in the Red River Settlement, he farmed, hunted, traded, and taught school before becoming a legislator, cabinet minister, and, from 1878 to 1887, premier of Manitoba. Once described as Louis Riel’s alter ego, he skirmished with prime minister John A. Macdonald, clashed with railway baron George Stephen, and endured racist taunts while championing the interests of the Prairie West in battles with investment bankers, Ottawa politicians, and the CPR. His contributions to the development of Canada’s federal system and his dealings with issues of race and racism deserve attention today. Recounted here by Canadian historian Gerald Friesen, Norquay’s life story ignites contemporary conversations around the nature of empire and Canada’s own imperial past. Drawing extensively on recently opened letters and financial papers that offer new insights into his business, family, and political life, Friesen reveals Norquay to be a thoughtful statesman and generous patriarch. This masterful biography of the Premier from Red River sheds welcome light on a neglected historical figure and a tumultuous time for Canada and Manitoba.AQA A Level Physics Student Book 1

Par Gerald Blaine, Lisa McCubbin Hill. 2010
The New York Times bestselling and extraordinary true story of the critical events leading up to and following the assassination…
of President John F. Kennedy, as told by the Secret Service agents who were firsthand witnesses to one of America&’s greatest tragedies.The Secret Service. An elite team of men who share a single mission: to protect the president of the United States. On November 22, 1963, these men failed—and a country would never be the same. Now, for the first time, a member of JFK&’s Secret Service detail reveals the inside story of the assassination, the weeks and days that led to it and its heartrending aftermath. This extraordinary book is a moving, intimate portrait of dedication, courage, and loss. Drawing on the memories of his fellow agents, Jerry Blaine captures the energetic, crowd-loving young president, who banned agents from his car and often plunged into raucous crowds with little warning. He describes the careful planning that went into JFK&’s Texas swing, the worries and concerns that agents, working long hours with little food or rest, had during the trip. And he describes the intensely private first lady making her first-ever political appearance with her husband, just months after losing a newborn baby. Here are vivid scenes that could come only from inside the Kennedy detail: JFK&’s last words to his tearful son when he left Washington for the last time; how a sudden change of weather led to the choice of the open-air convertible limousine that day; Mrs. Kennedy standing blood-soaked outside a Dallas hospital room; the sudden interruption of six-year-old Caroline&’s long-anticipated sleepover with a friend at home; the exhausted team of agents immediately reacting to the president&’s death with a shift to LBJ and other key governmental figures; the agents&’ dismay at Jackie&’s decision to walk openly from the White House to St. Matthew&’s Cathedral at the state funeral. Most of all, this is a look into the lives of men who devoted their entire beings to protecting the presidential family: the stress of the secrecy they kept, the emotional bonds that developed, the terrible impact on agents&’ psyches and families, and their astonishment at the country&’s obsession with far-fetched conspiracy theories and finger-pointing. A book fifty years in coming, The Kennedy Detail is a portrait of incredible camaraderie and incredible heartbreak—a true, must-read story of heroism in its most complex and human form.
