Since humans first looked up at the stars, astronomy has had a particular ability to stir the imagination and challenge the thinking of scientists and non-scientists alike. Astronomy: The Human Quest for Understanding is an introductory astronomy textbook specifically designed to relate to non-science majors across a wide variety of disciplines, nurture their curiosity, and develop vital science-based critical-thinking skills. This textbook provides an introduction to how science operates in practice and what makes it so successful in uncovering nature's secrets. Given that the study of astronomy dates back thousands of years, it is the ideal subject for tracing the development of the physical sciences and how our evolving understanding of nature has influenced, and been influenced by, mathematics, philosophy, religion, geography, politics, and more. This historical approach also illustrates how wrong turns have been taken, and how the inherent self-correcting nature of science through constant verification and the falsifiability of truly scientific theories ultimately leads us back to a more productive path in our quest for understanding. This approach also points out why, as a broadly educated citizenry, students of all disciplines must understand how scientists arrive at conclusions, and how science and technology have become central features of modern society. In discussing this fascinating and beautiful universe of which we are a part, it is necessary to illustrate the fundamental role that mathematics plays in decoding nature's mysteries. Unlike other similar textbooks, some basic mathematics is integrated naturally into the text, together with interpretive language, and supplemented with numerous examples; additional tutorials are provided on the book's companion website. Astronomy: The Human Quest for Understanding leads the reader down the path to our present-day understanding of our Solar System, stars, galaxies, and the beginning and evolution of our universe, along with profound questions still to be answered in this ancient, yet rapidly changing field.

This concise textbook, the first volume in the Ohio State Astrophysics Series, covers all aspects of the interstellar and intergalactic medium for graduate students and advanced undergraduates. This series aims to impart the essential knowledge on a topic that every astrophysics graduate student should know, without going into encyclopedic depth. This text includes a full discussion of the circumgalactic medium, which bridges the space between the interstellar and intergalactic gas, and the hot intracluster gas that fills clusters of galaxies. Its breadth of coverage is innovative, as most current textbooks treat the interstellar medium in isolation. The authors emphasise an order-of-magnitude understanding of the physical processes that heat and cool the low-density gas in the universe, as well as the processes of ionization, recombination, and molecule formation. Problems at the end of each chapter are supplemented by online projects, data sets and other resources.

IAU Symposium 356 summarises the most recent results in the field of active galaxies and active galactic nuclei (AGN). These are some of the most luminous sources in the Universe, also the most distant ones that we can observe, so they are very important for understanding the early Universe and its evolution through cosmic time. This volume gives an overview of the current status in the field of active galaxies including: AGN multiwavelength observations; different AGN types and their properties; AGN variability; active supermassive black holes and properties of galaxies in which they reside; triggering, feedback and shutting off AGN activity; relativistic jets and environments of active galaxies; and AGN evolution. IAU S356 was the third IAU symposium organised in Africa in the past 100 years since the IAU was established, and the first one organised in Ethiopia, highlighting current developments in astronomical research in Africa.

'Brilliant. You won't find a clearer, more engaging guide to what we know (or would like to know) about the universe and how it is put together' Bill Bryson Celebrated physicist and global bestselling author Paul Davies tells the story of the universe in thirty cosmological conundrums In the constellation of Eridanus there lurks a cosmic mystery. It's as if something has taken a huge bite out of the universe, leaving a super-void. What could be the culprit? A super massive black hole? Another, bigger universe? Or an expanding vacuum bubble, destined to envelop and annihilate everything in existence? Scientists now understand the history of our universe better than the history of our own planet, but they continue to uncover startling new riddles-the hole in the universe being just one. In this electrifying book, award-winning physicist Paul Davies walks us through the puzzles and paradoxes that have preoccupied cosmologists from ancient Greece to the present day. Laying bare the audacious research that has led us to mind-bending solutions, Davies reveals how we might begin to approach the greatest outstanding enigmas of all.

From One of the Most Brilliant Minds of Our Time

The first three billion years of cosmic time were the prime epoch of galaxy formation. Characterising galaxies at this epoch is therefore crucial to achieving a major goal of modern astrophysics: to understand how galaxies such as our Milky Way emerged from the primordial density fluctuations in the early Universe and how they evolved through cosmic time. Recent major international investments in observing facilities such as the Atacama Large Millimetre Array (ALMA) and the James Webb Space Telescope (JWST) promise to provide the next leap in our understanding of this topic. This volume gathers the scientific contributions to the International Astronomical Union Symposium 352, which was devoted to this topic. The community of theoretical and observational experts discuss how we can make the most of ALMA and JWST synergies in advancing our understanding of galaxy evolution in the young Universe.

This book presents interesting mathematical questions of relativity theory and relations to modern astrophysics, as well as various conceptual foundations. Topics discussed include the generalised Lorentz transformations and the velocity transformation; fundamental physics; non-Newtonian gravity effect; dark matter and dark energy concepts; pseudo-complex variables and antisymmetric tensor fields. This book will be useful for academic professors, professional researchers in physics and mathematics, postgraduate students and all remaining people interested in theoretical physics and astrophysics.

Providing a definitive history of the formative years of radio astronomy, this book is invaluable for historians of science, scientists and engineers. The whole of worldwide radio and radar astronomy is covered, beginning with the discoveries by Jansky and Reber of cosmic noise before World War II, through the wartime detections of solar noise, the discovery of radio stars, lunar and meteor radar experiments, the detection of the hydrogen spectral line, to the discoveries of Hey, Ryle, Lovell and Pawsey in the decade following the war, revealing an entirely different sky from that of visual astronomy. Using contemporary literature, correspondence and photographs, the book tells the story of the people who shaped the intellectual, technical, and social aspects of the field now known as radio astronomy. The book features quotes from over a hundred interviews with pioneering radio astronomers, giving fascinating insights into the development of radio astronomy. Woodruff T. Sullivan III has been awarded the 2012 Leroy E. Doggett Prize for Historical Astronomy.

Neutron Scattering: Applications in Chemistry, Materials Science and Biology, Volume 49, provides an in-depth overview of the applications of neutron scattering in the fields of physics, materials science, chemistry, biology, the earth sciences, and engineering. The book describes the tremendous advances in instrumental, experimental, and computational techniques over the past quarter-century. Examples include the coming-of-age of neutron reflectivity and spin-echo spectroscopy, the advent of brighter accelerator-based neutron facilities and associated techniques in the United States and Japan over the past decade, and current efforts in Europe to develop long-pulse, ultra-intense spallation neutron sources. It acts as a complement to two earlier volumes in the Experimental Methods in the Physical Science series, Neutron Scattering: Fundamentals(Elsevier 2013) and Neutron Scattering: Magnetic and Quantum Phenomena (Elsevier 2015). As a whole, the set enables researchers to identify aspects of their work where neutron scattering techniques might contribute, conceive the important experiments to be done, assess what is required, write a successful proposal for one of the major facilities around the globe, and perform the experiments under the guidance of the appropriate instrument scientist.

An engaging critique of the science and metaphysics behind our understanding of the universe   The James Webb Space Telescope, when launched in 2021, will be the premier orbital observatory, capable of studying every phase of the history of the universe, from the afterglow of the Big Bang to the formation of our solar system. Examining the theoretical basis for key experiments that have made this latest venture in astrophysics possible, Bjørn Ekeberg reveals that scientific cosmology actually operates in a twilight zone between the physical and metaphysical.  Metaphysical Experiments explains how our current framework for understanding the universe, the Big Bang theory, is more determined by a deep faith in mathematical universality than empirical observation. Ekeberg draws on philosophical insights by Spinoza, Bergson, Heidegger, and Arendt; on the critical perspectives of Latour, Stengers, and Serres; and on cutting-edge physics research at the Large Hadron Collider, to show how the universe of modern physics was invented to reconcile a Christian metaphysical premise with a claim to the theoretical unification of nature. By focusing on the nonmathematical assumptions underlying some of the most significant events in modern science, Metaphysical Experiments offers a critical history of contemporary physics that demystifies such concepts as the universe, particles, singularity, gravity, blackbody radiation, the speed of light, wave/particle duality, natural constants, black holes, dark matter, and dark energy. Ekeberg’s incisive reading of the metaphysical underpinnings of scientific cosmology offers an innovative account of how we understand our place in the universe.

From H.G. Wells to Isaac Asimov to Ursula K. Le Guin, time travel has long been a favorite topic and plot device in tales of science fiction and fantasy. But as any true SF fan knows, astounding stories about traversing alternate universes and swimming the tides of time demand plausible science. That's just what Paul J. Nahin's guide provides.

An engineer, physicist, and published science fiction writer, Nahin is uniquely qualified to explain the ins and outs of how to spin such complex theories as worm holes, singularity, and relativity into scientifically sound fiction. First published in 1997, this fast-paced book discusses the common and not-so-common time-travel devices science fiction writers have used over the years, assesses which would theoretically work and which would not, and provides scientific insight inventive authors can use to find their own way forward or backward in time. From hyperspace and faster-than-light travel to causal loops and the uncertainty principle and beyond, Nahin's equation-free romp across time will help writers send their characters to the past or future in an entertaining, logical, and scientific way.

If you ever wanted to set up the latest and greatest grandfather paradox--or just wanted to know if the time-bending events in the latest pulp you read could ever happen--then this book is for you.

Magnetic fields are important in the Universe and their effects contain the key to many astrophysical phenomena that are otherwise impossible to understand. This book presents an up-to-date overview of this fast-growing topic and its interconnections to plasma processes, astroparticle physics, high energy astrophysics, and cosmic evolution. The phenomenology and impact of magnetic fields are described in diverse astrophysical contexts within the Universe, from galaxies to galaxy clusters, the filaments and voids of the intergalactic medium, and out to the largest redshifts. The presentation of mathematical formulae is accessible and is designed to add insight into the broad range of topics discussed. Written for graduate students and researchers in physics, astrophysics and related disciplines, this volume will inspire readers to devise new ways of thinking about magnetic fields in space on galaxy scales and beyond.

The third part of the book reviews the methods to calculate gravitational waveforms. The fourth and last part of the book covers techniques employed in gravitational wave astronomy data analysis. This book represents both a valuable resource for graduate students and an important reference for researchers in gravitational wave astronomy.

'An incredible tour of our universe's greatest mysteries' Professor Dan Hooper This cutting-edge book investigates the extraordinary potential of multimessenger astronomy to revolutionise our understanding of the universe The spectacular advances of modern astronomy have opened our horizon on an unexpected cosmos: a dark, mysterious universe, populated by enigmatic entities we know very little about, like black holes, or nothing at all, like dark matter and dark energy. This book discusses the extraordinary potential of a new discipline dubbed 'multimessenger astronomy', combining the traditional approach based on the observation of light from celestial objects, with a new method based on other 'messengers' - such as gravitational waves, neutrinos, and cosmic rays - that carry information from otherwise inaccessible corners of the universe. Interweaving the discussion of multimessenger astronomy with an exploration of the surprising connections between the study of the universe on the largest scales, and the physics of the infinitely small, this text provides an accessible and fascinating introduction to cutting-edge findings in recent cosmology which could soon revolutionize our understanding of the universe.

Tensors, Relativity, and Cosmology, Second Edition, combines relativity, astrophysics, and cosmology in a single volume, providing a simplified introduction to each subject that is followed by detailed mathematical derivations. The book includes a section on general relativity that gives the case for a curved space-time, presents the mathematical background (tensor calculus, Riemannian geometry), discusses the Einstein equation and its solutions (including black holes and Penrose processes), and considers the energy-momentum tensor for various solutions. In addition, a section on relativistic astrophysics discusses stellar contraction and collapse, neutron stars and their equations of state, black holes, and accretion onto collapsed objects, with a final section on cosmology discussing cosmological models, observational tests, and scenarios for the early universe. This fully revised and updated second edition includes new material on relativistic effects, such as the behavior of clocks and measuring rods in motion, relativistic addition of velocities, and the twin paradox, as well as new material on gravitational waves, amongst other topics.

Masers are the microwave analogue of lasers; there are many astronomical sources of natural maser emission, including gas around forming and dying stars, and around supermassive black holes. These bright sources of microwaves are fascinating in their own right and provide unique abilities to probe details of astronomical sources. Molecular maser emission studies address important questions in the formation and evolution of stars, the structure of our Milky Way Galaxy, the characteristics of supermassive black holes, and fundamental parameters of cosmology. More than 100 astronomers from around the world gathered in Cagliari, Sardinia, for IAU Symposium 336 to discuss the latest findings related to masers. These proceedings summarize state of the art observations and theories pertaining to astrophysical masers and their environments, for graduate students and researchers. As new radio telescope facilities come online, observations of masers will continue to shed light on a broad range of important astrophysical problems.

An Introduction to Molecular Clouds describes the formation of molecular clouds and the innovative features of molecular clouds with different physical parameters. In this book, Jean-gravitational instability is discussed with different physical parameters, which is the major cause of the formation of molecular clouds in the interstellar medium (ISM), and the way molecular clouds are formed in the astrophysical plasma environment is described. The authors aim to determine the basic conditions responsible for the formation of heavenly bodies in the universe. The book deals with radiative instability in a variety of conditions incorporating different physical parameters such as viscosity, rotation, permeability, porosity, thermal conductivity, Hall current, Finite ion Larmor radius corrections, finite electrical resistivity, radiative heat-loss functions and finite electron inertia, both in gaseous plasma and quantum plasma environments.

Humanity's first reusable spacecraft and the most complex machine ever built, NASA's Space Shuttle debuted with great promise and as a dependable source of wonder and national pride. But with the Challenger catastrophe in 1986, the whole Space Shuttle program came into question, as did NASA itself, so long an institution that was seemingly above reproach. Wheels Stop tells the stirring story of how, after the Challenger disaster, the Space Shuttle not only recovered but went on to perform its greatest missions. From the Return to Flight mission of STS-26 in 1988 to the last shuttle mission ever on STS-135 in 2011, Wheels Stop takes readers behind the scenes as the shuttle's crews begin to mend Cold War tensions with the former Soviet Union, conduct vital research, deploy satellites, repair the Hubble Space Telescope, and assist in constructing the International Space Station. It also tells the heart-wrenching story of the Columbia tragedy and the loss of the magnificent STS-107 crew. As complex as the shuttle was, the people it carried into orbit were often more so-and this is their story, too. Close encounters with astronauts, flight controllers, and shuttle workers capture the human side of the Space Shuttle's amazing journey-and invite readers along for the ride.

Il libro e basato sulle lezioni attualmente tenute dall'autore presso l'Universita di Bari, ed e progettato in modo da rappresentare un testo di riferimento il piu possibile moderno, completo e autosufficiente per i corsi semestrale di Cosmologia, Astrofisica o Fisica Astroparticellare che compaiono nel piano di studi della Laurea Magistrale in Fisica e in Astronomia. Contiene gli elementi di base della cosmologia relativistica, del modello cosmologico standard e del suo completamento inflazionario. E' organizzato per servire da traccia ad un corso di cosmologia di stampo teorico, ma cerca di non perdere mai di vista il confronto con i principali risultati osservativi: molta attenzione viene infatti dedicata alla fenomenologia dei fondi cosmici, e in particolare alla radiazione gravitazionale fossile perche la sua rivelazione, diretta o indiretta, potrebbe dare indicazioni cruciali sulla scelta del corretto modello per l'Universo primordiale. Non mancano infine alcuni accenni ad argomenti di interesse emergente, di tipo teorico-fenomenologico, come lo studio dell'effetto di "deriva" del redshift, la cosmologia delle membrane, e il problema delle medie cosmologiche fatte su ipersuperfici spaziali (o nulle) non omogenee."

La realizzazione e il lancio nello spazio di satelliti o sonde attraverso missili o navette spaziali sono un esempio di attivita industriale di enorme complessita e di lungo periodo. Lo sviluppo di un programma spaziale prevede la realizzazione di vari sistemi costituenti: il segmento spaziale, cioe i lanciatori per l'accesso allo Spazio, i satelliti o le sonde, le infrastrutture spaziali abitate da astronauti oppure robotizzate; e il segmento di terra che consente agli operatori sulla terra di controllare i sistemi nello spazio e di fruire delle applicazioni derivanti dal loro uso.

Il settore e di per se peculiare dato l'ambiente extra-atmosferico ove si troveranno ad operare astronauti o sonde robotizzate, pertanto la manifattura dei sistemi spaziali e una pratica a meta strada tra la scienza esatta e l'artigianato di elevatissima qualita.

Le metodologie e i processi realizzativi dei programmi spaziali hanno pero avuto il pregio nel passato di costituire, sin dagli anni '60, un modello di riferimento per altri settori industriali proprio a causa della loro unicita tecnologica e produttiva. E oggi le metodologie di gestione dei programmi spaziali sono standardizzate e consolidate.

Gli elementi trattati in questo libro intendono avvicinare

il lettore alle specificita gestionali della concezione, del finanziamento e della messa in essere di un programma spaziale, una tra le piu complesse attivita umane influenzate da fattori storici, scientifici, economici e politici.

The Physics of Stars, Second Edition provides a concise, self-contained account of how key aspects of stellar structure, evolution and nucleosynthesis can be understood in terms of fundamental physics. Beginning with an introduction to astrophysical concepts using elementary physics, the book progresses to consider stellar properties in terms of more advanced physical ideas all of which are carefully explained before they are applied. The result is a balanced presentation of both fundamental physics and astrophysics. A major strength of the book is that the author does not evade challenging concepts, but carefully explains them, enabling the reader to gain a fuller understanding of the theory. Carefully revised, this second edition now includes a chapter on Helioseismology. Review of the Second Edition

"This book is…a superb textbook in terms of choice of content, its organisation and style of presentation. Phillips is one of the best of the currently available texts - its coverage, level, style and price are all in its favour." Dr M. Wilson Royal Holloway College, University of London Review of the First Edition

"The title tells it all: This is a compact and well-organised book… and it achieves wonderful success in presenting the physics, of approximation, intuition and understanding. Its strengths are many." Physics Today

"Phillips never lets the student out of his sight. And this student is encouraged, step-by-step, to reach a greater understanding of the subject. Every paragraph seems to be honed on tutorial experience, every equation is explained with wit great care, superfluous material is omitted and concepts are worked out from first principles. This is a university textbook par excellence, a classic that will be used for decades to come." New Scientist
