924 Elementary Problems and Answers in Solar System Astronomy

Van Allen, James A.

University of Iowa Press, 1993

This challenging collection of problems is organized into seven carefully crafted, thoughtful chapters on the Sun and the nature of the solar system; the motion of the planets; the Sun, Earth, and Moon; the sky as observed from the rotating, revolving Earth; other planets, their satellites, their rings; asteroids, comets, and meteoroids; and the radiations and telescopes. From question 1, "List characteristics of the solar system that are major clues in devising a hypothesis of its origin and evolution," through question 924, "Give a brief list of the contributions of radio and radar technologies in lunar and planetary astronomy," the problems range in difficulty from ones requiring only simple knowledge to ones requiring significant understanding and analysis. Many of the answers, in turn, illuminate the questions by providing basic explanations of the concepts involved.

Pioneer 10 and 11 are now halfway to the edge of the solar system. All beginning and advanced students of astronomy and their instructors as well as all dedicated amateurs can join James Van Allen on this journey by exploring the questions and answers in this stimulating book.

A Final Story

Science, Myth, and Beginnings

Nasser Zakariya

University of Chicago Press, 2017

Popular science readers embrace epics—the sweeping stories that claim to tell the history of all the universe, from the cosmological to the biological to the social. And the appeal is understandable: in writing these works, authors such as E. O. Wilson or Steven Weinberg deliberately seek to move beyond particular disciplines, to create a compelling story weaving together natural historical events, scientific endeavor, human discovery, and contemporary existential concerns.

In A Final Story, Nasser Zakariya delves into the origins and ambitions of these scientific epics, from the nineteenth century to the present, to see what they reveal about the relationship between storytelling, integrated scientific knowledge, and historical method. While seeking to transcend the perspectives of their own eras, the authors of the epics and the debates surrounding them are embedded in political and social struggles of their own times, struggles to which the epics in turn respond. In attempts to narrate an approach to a final, true account, these synthesizing efforts shape and orient scientific developments old and new. By looking closely at the composition of science epics and the related genres developed along with them, we are able to view the historical narrative of science as a form of knowledge itself, one that discloses much about the development of our understanding of and relationship to science over time.

An Introduction to Nuclear Astrophysics

Richard N. Boyd

University of Chicago Press, 2008

Nuclear astrophysics is the study of how all naturally occurring elements formed and evolved into our present universe via nuclear processes, beginning with the Big Bang and continuing today in astrophysical objects such as stars, x-ray bursters, and supernovae. Emerging from traditional studies in astrophysics and particle research, this cross-disciplinary field touches upon astronomy, astrophysics, cosmology, and particle physics.

In An Introduction to Nuclear Astrophysics, author Richard Boyd includes basic nomenclature and information so that students from astronomy or physics can quickly orient themselves in the material. Subsequent chapters describe earthbound and space born instruments operating in service to nuclear astrophysics worldwide; background topics such as nuclear and neutrino physics, scattering formalism, and thermonuclear reaction rates; and information on galactic chemical evolution, solar nucleosynthesis, s- and r-processes, and gamma-ray bursts. Each chapter includes problem sets  against which students may test their knowledge before moving ahead, and the author has included copious references intended to guide students to further study.

An Introduction to Nuclear Astrophysics
is an essential textbook for undergraduate and graduate students in astronomy and astrophysics.  It is also an invaluable overview of the subject for researchers in nuclear astrophysics and related fields.

cover of Aurora Watcher's Handbook

Aurora Watcher's Handbook

Neil Davis

University of Alaska Press, 1992

Neil Davis's decades-long involvement with the aurora extends beyond study and research. He has also been explaining this magnificent phenomenon to diverse audiences, sharing the knowledge with his graduate students and his grandchildren, with his fellow scientists through professional publications, and with the general public through newspaper columns. His ability to communicate both the facts and the wonder of the northern lights shows clearly in this book.

Starting at a basic level, the handbook begins appropriately with matters of immediate concern to someone who hopes to see an auroral display: what causes the aurora, where and when it is most often seen, and how best to capture it on film. Later sections provide a thorough and clear review of all aspects of auroral science, including the mysterious realm of auroral sound. In a concise and readable fashion, the handbook covers what is known about auroras, encompassing overviews of the northern Natives' legends and myths and the several theories geophysicists have produced to explain why auroras behave as they do. The Aurora Watcher's Handbook includes numerous illustrations, ranging from cartoons to color plates and drawings. 

 

"I am confident [this book] will become the aurora watcher's bible for many years to come." (Sky & Telescope)

"This is participatory science at its best!" (Midwest Book Review)

"A delightful book, highly recommended." (CHOICE )

"A complete course for the layman with an interest in the northern lights." (Fairbanks Daily News-Miner)

"[Davis] has written the book in a smooth, how-it-works style, and his presentation is remarkably clear. . . . [He] expended much effort on this book, forming from his lifetime of knowledge a coherent and comprehensible picture of the aurora for the non-specialist." (ARCTIC)

"For a comprehensive guide to the northern lights, read Neil Davis's The Aurora." (Small Press Magazine)

cover of Battle of the Big Bang: The New Tales of Our Cosmic Origins

Battle of the Big Bang

The New Tales of Our Cosmic Origins

Niayesh Afshordi and Phil Halper

University of Chicago Press, 2025

“Excellent.”—Steven Poole, The Wall Street Journal • “Terrific.”—Liz Else, New Scientist (Best Popular Science Books of 2025 So Far) • “A brilliant overview of the state of modern cosmology.”—Alex O'Connor, alexoconnor.com • “This will expand readers’ minds.”—Publishers Weekly • One of Smithsonian's Ten Best Science Books of 2025
 
“An intellectual feast.”—Carlo Rovelli • “A must-read.”—Sabine Hossenfelder • “Wonderfully broad and open-minded.”—Roger Penrose • “Remarkable.”—Brian Keating

A thrilling exploration of competing cosmological origin stories, comparing new scientific ideas that upend our very notions of space, time, and reality.
 
By most popular accounts, the universe started with a bang some 13.8 billion years ago. But what happened before the Big Bang? And how do we know it happened at all? Here prominent cosmologist Niayesh Afshordi and science communicator Phil Halper offer a tour of the peculiar possibilities: bouncing and cyclic universes, time loops, creations from nothing, multiverses, black hole births, string theories, and holograms. Along the way, they offer both a call for new physics and a riveting story of scientific debate.
 
Incorporating insights from Afshordi’s cutting-edge research and Halper’s original interviews with scientists like Stephen Hawking, Roger Penrose, and Alan Guth, Battle of the Big Bang compares these models for the origin of our origins, showing each theory’s strengths and weaknesses and explaining new attempts to test these notions. Battle of the Big Bang is a tale of rivalries and intrigue, of clashes of ideas that have raged from Greek antiquity to the present day over whether the universe is eternal or had a beginning, whether it is unique or one of many. But most of all, Afshordi and Halper show that this search is filled with wonder, discovery, and community—all essential for remembering a forgotten cosmic past.

Bennu 3-D

Anatomy of an Asteroid

Dante Lauretta, Brian May, Carina A. Bennett, Kenneth S. Coles, Claudia Manzoni, and C. W. V. Wolner

University of Arizona Press, 2023

Bennu, named for the ancient Egyptian phoenix, was the chosen destination of OSIRIS-REx, NASA’s premier mission of asteroid exploration, launched in 2016. Study of the asteroid is important in safeguarding the future of planet Earth, but Bennu is also a time capsule from the dawn of our Solar System, holding secrets over four-and-a-half billion years old about the origin of life and Earth as a habitable planet.

In 2020 the OSIRIS-REx spacecraft successfully landed on the surface of Bennu and collected pristine asteroid material for delivery to Earth in September 2023. Scientific studies of the samples, along with data collected during the rendezvous, promise to help find answers to some of humanity’s deepest questions: Where did we come from? What is our destiny in space?

This book, the world’s first complete (and stereoscopic) atlas of an asteroid, is the result of a unique collaboration between OSIRIS-REx mission leader Dante Lauretta and Brian May’s London Stereoscopic Company. Lauretta’s colleagues include Carina Bennett, Kenneth Coles, and Cat Wolner, as well as Brian May and Claudia Manzoni, who became part of the ultimately successful effort to find a safe landing site for sampling. The text details the data collected by the mission so far, and the stereo images have been meticulously created by Manzoni and May from original images collected by the OSIRIS-REx cameras.

An Illustrated History of Astronomy and Cosmology

John North

University of Chicago Press, 2008

For millennia humans have studied the skies to help them grow crops, navigate the seas, and earn favor from their gods. We still look to the stars today for answers to fundamental questions: How did the universe begin? Will it end, and if so, how? What is our place within it? John North has been examining such questions for decades. In Cosmos, he offers a sweeping historical survey of the two sciences that help define our place in the universe: astronomy and cosmology.
            Organizing his history chronologically, North begins by examining Paleolithic cave drawings that clearly chart the phases of the moon. He then investigates scientific practices in the early civilizations of Egypt, Greece, China, and the Americas (among others), whose inhabitants developed sophisticated methods to record the movements of the planets and stars. Trade routes and religious movements, North notes, brought these ancient styles of scientific thinking to the attention of later astronomers, whose own theories—such as Copernicus’ planetary theory—led to the Scientific Revolution.
            The work of master astronomers, including Ptolemy, Galileo, Kepler, and Newton, is described in detail, as are modern-day developments in astrophysics, such as the advent of radio astronomy, the brilliant innovations of Einstein, and the many recent discoveries brought about with the help of the Hubble telescope. This new edition brings North’s seminal book right up to the present day, as North takes a closer look at last year’s reclassification of Pluto as a “dwarf” planet and gives a thorough overview of current research.
            With more than two hundred illustrations and a comprehensive bibliography, Cosmos is the definitive history of astronomy and cosmology. It is sure to find an eager audience among historians of science and astronomers alike.

cover of Cracking the Einstein Code: Relativity and the Birth of Black Hole Physics

Cracking the Einstein Code

Relativity and the Birth of Black Hole Physics

Fulvio Melia

University of Chicago Press, 2009

Albert Einstein’s theory of general relativity describes the effect of gravitation on the shape of space and the flow of time. But for more than four decades after its publication, the theory remained largely a curiosity for scientists; however accurate it seemed, Einstein’s mathematical code—represented by six interlocking equations—was one of the most difficult to crack in all of science. That is, until a twenty-nine-year-old Cambridge graduate solved the great riddle in 1963. Roy Kerr’s solution emerged coincidentally with the discovery of black holes that same year and provided fertile testing ground—at long last—for general relativity. Today, scientists routinely cite the Kerr solution, but even among specialists, few know the story of how Kerr cracked Einstein’s code.

Fulvio Melia here offers an eyewitness account of the events leading up to Kerr’s great discovery. Cracking the Einstein Code vividly describes how luminaries such as Karl Schwarzschild, David Hilbert, and Emmy Noether set the stage for the Kerr solution; how Kerr came to make his breakthrough; and how scientists such as Roger Penrose, Kip Thorne, and Stephen Hawking used the accomplishment to refine and expand modern astronomy and physics. Today more than 300 million supermassive black holes are suspected of anchoring their host galaxies across the cosmos, and the Kerr solution is what astronomers and astrophysicists use to describe much of their behavior.

By unmasking the history behind the search for a real world solution to Einstein’s field equations, Melia offers a first-hand account of an important but untold story. Sometimes dramatic, often exhilarating, but always attuned to the human element, Cracking the Einstein Code is ultimately a showcase of how important science gets done.

Foundations of High-Energy Astrophysics

Mario Vietri

University of Chicago Press, 2008

Written by one of today’s most highly respected astrophysicists, Foundations of High-Energy Astrophysics is an introduction to the mathematical and physical techniques used in the study of high-energy astrophysics. Here, Mario Vietri approaches the basics of high-energy astrophysics with an emphasis on underlying physical processes as opposed to a more mathematical approach. Alongside more traditional topics, Vietri presents new subjects increasingly considered crucial to understanding high-energy astrophysical sources, including the electrodynamics of cosmic sources, new developments in the theory of standard accretion disks, and the physics of coronae, thick disks, and accretion onto magnetized objects.

The most thorough and engaging survey of high-energy astrophysics available today, Foundations of High-Energy Astrophysics introduces the main physical processes relevant to the field in a rigorous yet accessible way, while paying careful attention to observational issues. Vietri’s book will quickly become a classic text for students and active researchers in astronomy and astrophysics. Those in adjoining fields will also find it a valuable addition to their personal libraries.

From White Dwarfs to Black Holes

The Legacy of S. Chandrasekhar

Edited by G. Srinivasan

University of Chicago Press, 1999

From White Dwarfs to Black Holes chronicles the extraordinarily productive scientific career of Subrahmanyan Chandrasekhar, one of the twentieth century's most distinguished astrophysicists. Among Chandrasekhar's many discoveries were the critical mass that makes a star too massive to become a white dwarf and the mathematical theory of black holes. In 1983 he shared the Nobel Prize for Physics for these and other achievements.

Over the course of more than six decades of active research Chandrasekhar investigated a dizzying array of subjects. G. Srinivasan notes in the preface to this book that "the range of Chandra's contributions is so vast that no one person in the physics or astronomy community can undertake the task of commenting on his achievements." Thus, in this collection, ten eminent scientists evaluate Chandrasekhar's contributions to their own fields of specialization. Donald E. Osterbrock closes the volume with a historical discussion of Chandrasekhar's interactions with graduate students during his more than quarter century at Yerkes Observatory.

Contributors are James Binney, John L. Friedman, Norman R. Lebovitz, Donald E. Osterbrock, E. N. Parker, Roger Penrose, A. R. P. Rau, George B. Rybicki, E. E. Salpeter, Bernard F. Schutz, and G. Srinivasan.

Gravity's Ghost and Big Dog

Scientific Discovery and Social Analysis in the Twenty-First Century

Harry Collins

University of Chicago Press, 2013

Gravity’s Ghost and Big Dog brings to life science’s efforts to detect cosmic gravitational waves. These ripples in space-time are predicted by general relativity, and their discovery will not only demonstrate the truth of Einstein’s theories but also transform astronomy. Although no gravitational wave has ever been directly detected, the previous five years have been an especially exciting period in the field. Here sociologist Harry Collins offers readers an unprecedented view of gravitational wave research and explains what it means for an analyst to do work of this kind.
           
Collins was embedded with the gravitational wave physicists as they confronted two possible discoveries—“Big Dog,” fully analyzed in this volume for the first time, and the “Equinox Event,” which was first chronicled by Collins in Gravity’s Ghost. Collins records the agonizing arguments that arose as the scientists worked out what they had seen and how to present it to the world, along the way demonstrating how even the most statistical of sciences rest on social and philosophical choices. Gravity’s Ghost and Big Dog draws on nearly fifty years of fieldwork observing scientists at the American Laser Interferometer Gravitational Wave Observatory and elsewhere around the world to offer an inspired commentary on the place of science in society today.

Gravity's Ghost

Scientific Discovery in the Twenty-first Century

Harry Collins

University of Chicago Press, 2010

In theory, at least, gravitational waves do exist. We are constantly bathed in gravitational radiation, which is generated when stars explode or collide and a portion of their mass becomes energy that ripples out like a disturbance on the surface of a serene pond. But unfortunately no gravitational wave has ever been directly detected even though the search has lasted more than forty years.

As the leading chronicler of the search for gravitational waves, Harry Collins has been right there with the scientists since the start. The result of his unprecedented access to the front lines of physical science is Gravity’s Ghost, a thrilling chronicle of high-stakes research and cutting-edge discovery. Here, Collins reveals that scientific discovery and nondiscovery can turn on scientific traditions and rivalries, that ideal statistical analysis rests on impossible procedures and unattainable knowledge, and that fact in one place is baseless assumption in another. He also argues that sciences like gravitational wave detection, in exemplifying how the intractable is to be handled, can offer scientific leadership a moral beacon for the twenty-first century. In the end, Gravity’s Ghost shows that discoveries are the denouements of dramatic scientific mysteries.

Gravity's Shadow

The Search for Gravitational Waves

Harry Collins

University of Chicago Press, 2004

According to the theory of relativity, we are constantly bathed in gravitational radiation. When stars explode or collide, a portion of their mass becomes energy that disturbs the very fabric of the space-time continuum like ripples in a pond. But proving the existence of these waves has been difficult; the cosmic shudders are so weak that only the most sensitive instruments can be expected to observe them directly. Fifteen times during the last thirty years scientists have claimed to have detected gravitational waves, but so far none of those claims have survived the scrutiny of the scientific community. Gravity's Shadow chronicles the forty-year effort to detect gravitational waves, while exploring the meaning of scientific knowledge and the nature of expertise.

Gravitational wave detection involves recording the collisions, explosions, and trembling of stars and black holes by evaluating the smallest changes ever measured. Because gravitational waves are so faint, their detection will come not in an exuberant moment of discovery but through a chain of inference; for forty years, scientists have debated whether there is anything to detect and whether it has yet been detected. Sociologist Harry Collins has been tracking the progress of this research since 1972, interviewing key scientists and delineating the social process of the science of gravitational waves.

Engagingly written and authoritatively comprehensive, Gravity's Shadow explores the people, institutions, and government organizations involved in the detection of gravitational waves. This sociological history will prove essential not only to sociologists and historians of science but to scientists themselves.

High-Energy Radiation from Magnetized Neutron Stars

Peter Mészáros

University of Chicago Press, 1992

Neutron stars, the most extreme state of matter yet confirmed, are responsible for much of the high-energy radiation detected in the universe. Mèszàros provides a general overview of the physics of magnetized neutron stars, discusses in detail the radiation processes and transport properties relevant to the production and propagation of high-energy radiation in the outer layers of these objects, and reviews the observational properties and theoretical models of various types of neutron star sources.

Horizons of Cosmology

Joseph Silk

Templeton Press, 2009

Horizons of Cosmology: Exploring Worlds Seen and Unseen is the fourth title published in the Templeton Science and Religion Series, in which scientists from a wide range of fields distill their experience and knowledge into brief tours of their respective specialties. In this volume, highly esteemed astrophysicist Joseph Silk explores the vast mysteries and speculations of the field of cosmology in a way that balances an accessible style for the general reader and enough technical detail for advanced students and professionals. Indeed, while the physical laws and origins of the universe can be endlessly complex, even Einstein once mused that they could be explained simply enough to be grasped by nonspecialists. To that end Silk begins by introducing the basic story of the major discoveries in cosmology over the past century—wherein we learned that we live in an expanding universe populated with galaxies and stars. The middle chapters examine a number of contemporary puzzles such as dark matter and dark energy. The last third of the book looks at the human side of cosmology and moves to the more philosophical frontiers of the field, such as concepts of multiverses and time travel—areas of exploration where some crossover into speculative territory becomes unavoidable. In the past century alone, our understanding of the universe has expanded exponentially, and it will be fascinating to see what discoveries the next hundred years hold. Few books will provide such a thorough understanding of where we have been and what might lie ahead as Horizons of Cosmology.

Inner Space/Outer Space

Edited by Edward Kolb, Michael Turner, Keith Olive, David Seckel, and David Lind

University of Chicago Press, 1986

Inner Space/Outer Space brings together much of the exciting work contributing to a new synthesis of modern physics. Particle physicists, concerned with the "inner space" of the atom, are making discoveries that their colleagues in astrophysics, studying outer space, can use to develop and test hypotheses about the events that occurred in the microseconds after the Big Bang and that shaped the universe as we know it today.

The papers collected here, from scores of scientists, constitute the proceedings of the first major international conference on research at the interface of particle physics and astrophysics, held in May 1984. The editors have written introductions to each major section that draw out the central themes and elaborate on the primary implications of the papers that follow.

James Van Allen

The First Eight Billion Miles

Abigail Foerstner

University of Iowa Press, 2009

Astrophysicist and space pioneer James Van Allen (1914–2006), for whom the Van Allen radiation belts were named, was among the principal scientific investigators for twenty-four space missions, including Explorer I in 1958, the first successful U.S. satellite; Mariner 2’s 1962 flyby of Venus, the first successful mission to another planet; and the 1970s Pioneer 10 and Pioneer 11 missions that surveyed Jupiter and Saturn. Although he retired as a University of Iowa professor of physics and astronomy in 1985, he remained an active researcher, using his campus office to monitor data from Pioneer 10—on course to reach the edge of the solar system when its signal was lost in 2003—until a short time before his death at the age of ninety-one. Now Abigail Foerstner blends space science drama, military agendas, cold war politics, and the events of Van Allen’s lengthy career to create the first biography of this highly influential physicist.

Drawing on Van Allen’s correspondence and publications, years of interviews with him as well as with more than a hundred other people, and declassified documents from such archives as the Jet Propulsion Laboratory, the Kennedy Space Center, and the Applied Physics Laboratory, Foerstner describes Van Allen’s life from his Iowa childhood to his ?rst experiments at White Sands to the years of Explorer I until his death in 2006.

Often called the father of space science, James Van Allen led the way to mapping a new solar system based on the solar wind, massive solar storms, and cosmic rays. Pioneer 10 alone sent him more than thirty years of readings that helped push our recognition of the boundary of the solar system billions of miles past Pluto. Abigail Foerstner’s compelling biography charts the eventful life and time of this trailblazing physicist.

Metaphysical Experiments

Physics and the Invention of the Universe

Bjørn Ekeberg

University of Minnesota Press, 2019

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.

Physical Processes in Circumstellar Disks around Young Stars

Edited by Paulo J. V. Garcia

University of Chicago Press, 2011

Circumstellar disks are vast expanses of dust that form around new stars in the earliest stages of their birth. Predicted by astronomers as early as the eighteenth century, they weren’t observed until the late twentieth century, when interstellar imaging technology enabled us to see nascent stars hundreds of light years away. Since then, circumstellar disks have become an area of intense study among astrophysicists, largely because they are thought to be the forerunners of planetary systems like our own—the possible birthplaces of planets.

            
This volume brings together a team of leading experts to distill the most up-to-date knowledge of circumstellar disks into a clear introductory volume. Understanding circumstellar disks requires a broad range of scientific knowledge, including chemical processes, the properties of dust and gases, hydrodynamics and magnetohydrodynamics, radiation transfer, and stellar evolution—all of which are covered in this comprehensive work, which will be indispensable for graduate students, seasoned researchers, or even advanced undergrads setting out on the study of planetary evolution.

Quantum Field Theory in Curved Spacetime and Black Hole Thermodynamics

Robert M. Wald

University of Chicago Press, 1994

A clear and concise introduction to quantum field theory in curved spacetime

In this book, Robert Wald provides a coherent, pedagogical introduction to the formulation of quantum field theory in curved spacetime. He begins with a treatment of the ordinary one-dimensional quantum harmonic oscillator, progresses through the construction of quantum field theory in flat spacetime to possible constructions of quantum field theory in curved spacetime, and, ultimately, to an algebraic formulation of the theory. In his presentation, Wald disentangles essential features of the theory from inessential ones (such as a particle interpretation) and clarifies relationships between various approaches to the formulation of the theory. He also provides a comprehensive, up-to-date account of the Unruh effect, the Hawking effect, and some of its ramifications. In particular, the subject of black hole thermodynamics, which remains an active area of research, is treated in depth.

This book will be accessible to students and researchers who have had introductory courses in general relativity and quantum field theory, and will be of interest to scientists in general relativity and related fields.

Quantum Legacies

Dispatches from an Uncertain World

David Kaiser

University of Chicago Press, 2024

A series of engaging essays that explore iconic moments of discovery and debate in physicists’ ongoing quest to understand the quantum world.

The ideas at the root of quantum theory remain stubbornly, famously bizarre: a solid world reduced to puffs of probability; particles that tunnel through walls; cats suspended in zombielike states, neither alive nor dead; and twinned particles that share entangled fates. For more than a century, physicists have grappled with these conceptual uncertainties while enmeshed in the larger uncertainties of the social and political worlds around them, a time pocked by the rise of fascism, cataclysmic world wars, and a new nuclear age.
 
In Quantum Legacies, David Kaiser introduces readers to iconic episodes in physicists’ still-unfolding quest to understand space, time, and matter at their most fundamental. In a series of vibrant essays, Kaiser takes us inside moments of discovery and debate among the great minds of the era—Albert Einstein, Erwin Schrödinger, Stephen Hawking, and many more who have indelibly shaped our understanding of nature—as they have tried to make sense of a messy world.
 
Ranging across space and time, the episodes span the heady 1920s, the dark days of the 1930s, the turbulence of the Cold War, and the peculiar political realities that followed. In those eras as in our own, researchers’ ambition has often been to transcend the vagaries of here and now, to contribute lasting insights into how the world works that might reach beyond a given researcher’s limited view. In Quantum Legacies, Kaiser unveils the difficult and unsteady work required to forge some shared understanding between individuals and across generations, and in doing so, he illuminates the deep ties between scientific exploration and the human condition.

Relativistic Astrophysics, 2

The Structure and Evolution of the Universe

Ya. B. Zel'dovich and I. D. Novikov

University of Chicago Press, 1983

Though the kinematics of the evolving universe became known decades ago, research into the physics of processes occurring in the expanding universe received a reliable observational and theoretical basis only in more recent years. These achievements have led in turn to the emergence of new problems, on which an unusually active assault has begun.

This second volume of Relativistic Astrophysics provides a remarkably complete picture of the present state of cosmology. It is a synthesis of the theoretical foundations of contemporary cosmology, which are derived from work in relativity, plasma theory, thermodynamics, hydrodynamics, and particle physics. It presents the theoretical work that explains, describes, and predicts the nature of the universe, the physical process that occur in it, the formation of galaxies, the synthesis of the light elements, and the cosmological singularity and the theory of gravitation.

This book, long and eagerly awaited, is essential for everyone whose work is related to cosmology and astrophysics.

This volume is divided into four sections. The first, on dynamical friction and Brownian motion, includes papers written after Chandrasekhar published his 1942 monograph Principles of Stellar Dynamics. Also in this section is "Stochastic Problems in Physics and Astronomy," one of the most cited papers in the physics literature, as well as papers written jointly with John von Neumann that have been given impetus to recent research. As Chandrasekhar notes, the papers in the second section, on statistical problems in astronomy, were influenced by Ambartsumian's analysis of brightness in the Milky Way. A third section on the statistical theory of turbulence addresses issues still unresolved in fluid dynamics, and the last section is devoted to hydromagnetic problems in astrophysics that are not discussed in Chandrasekhar's monographs.

Relativistic Astrophysics

S. Chandrasekhar

University of Chicago Press, 1990

This is the fifth of six volumes collecting significant papers of the distinguished astrophysicist and Nobel laureate S. Chandrasekhar. His work is notable for its breadth as well as for its brilliance; his practice has been to change his focus from time to time to pursue new areas of research. The result has been a prolific career full of discoveries and insights, some of which are only now being fully appreciated.

Chandrasekhar has selected papers that trace the development of his ideas and that present aspects of his work not fully covered in the books he has periodically published to summarize his research in each area.

Volume 5 covers all of Chandrasekhar's contributions to the general theory of relativity and relativity's astrophysical applications (except his research on black holes and colliding gravitational waves, which is covered in Volume 6). The major topics include the influence of general relativity on the pulsations and stability of stars; the back reaction of gravitational waves on their sources; and post-Newtonian approximations to general relativity and their astrophysical applications. In addition to research papers, the volume includes two 1972 lectures in which Chandrasekhar assessed the past, present, and future of relativistic astrophysics. The foreword by astrophysicist Kip S. Thorne is an absorbing, brief history of the field since 1961, capturing the atmosphere of the early research and clarifying Chandrasekhar's dominant role in it.

Chandrasekhar has never written a monograph synthesizing his research in relativistic astrophysics, and therefore this volume of his papers serves as a summary of that work for students and more senior researchers.

The Non-Radial Oscillations of Stars in General Relativity and Other Writings

S. Chandrasekhar

University of Chicago Press, 1997

In these selections readers are treated to a rare opportunity to see the
world through the eyes of one of the twentieth century's most brilliant
and sensitive scientists. Conceived by Chandrasekhar as a supplement to
his Selected Papers, this volume begins with eight papers he
wrote with Valeria Ferrari on the non-radial oscillations of stars. It
then explores some of the themes addressed in Truth and Beauty,
with meditations on the aesthetics of science and the world it examines.
Highlights include: "The Series Paintings of Claude Monet and the
Landscape of General Relativity," "The Perception of Beauty and the
Pursuit of Science," "On Reading Newton's Principia at Age Past
Eighty," and personal recollections of Indira Gandhi, Jawaharlal Nehru,
and others.

Selected Papers, Volume 7 paints a picture of Chandra's universe,
filled with stars and galaxies, but with space for poetics, paintings,
and politics.

The late S. Chandrasekhar was best known for his discovery of the upper
limit to the mass of a white dwarf star, for which he received the Nobel
Prize in Physics in 1983. He was the author of many books, including
The Mathematical Theory of Black Holes and, most recently,
Newton's Principia for the Common Reader.

Star Day

A Story of 24 Hours and 24 Stellar Lives

Marcia Bartusiak and Stephen Lowe

University of Chicago Press, 2027

An hourly guide that tracks twenty-four stars, stellar clusters, and constellations across the sky to reveal their luminous lives and lore.

Over the course of a day, the constellations slowly shift, rising in the east and setting in the west, due to Earth’s rotation. A full turn of the celestial sphere, that bowl above us where the stars seemingly appear fixed to the surface, is completed once every twenty-four hours. In fact, the stars inspired the twenty-four-hour day, and one star, our Sun, rules the circadian rhythms of all life on our planet. This short book sweeps through the celestial sphere hour by hour, introducing a remarkable cast of stellar characters with each chapter. Celebrated science writer Marcia Bartusiak and mathematician Stephen Lowe blend practical astronomy with fascinating history to share unique cosmological stories.  

This husband and wife team explain that observers have long split the sky into twenty-four hours of right ascension—a celestial equivalent of longitude and a universal scheme for locating cosmological objects. Each chapter of Star Day presents a single right ascension hour, from the stellar death of S Andromedae (zeroth hour)—an explosion that helped reveal the size of the universe—to Scheat (twenty-third hour), an aging red giant. Twice the mass of the Sun and some 1,500 times as bright, Scheat sometimes guides amateur astronomers to distant galaxies. In between, we learn about humans’ pole star, Polaris (second hour), and meet the supermassive black hole at the center of our Milky Way galaxy (seventeenth hour). By the end of our star day, we will appreciate both our own stellar origins and the fragile and deep connections between human civilizations and the ever-changing heavens. Star Day reminds us that wonder and discovery are easily available, all for the simple price of looking up.

For each chapter, artist Matthew Green has depicted these stellar scenes with entrancing pen-and-ink drawings. Working together to narrate and illustrate these stars' stories, Bartusiak, Lowe, and Green have created an engaging read that is a perfect way to spend an hour or two—and a true gift to both seasoned skywatchers and curious beginners.

The Physics of Extragalactic Radio Sources

David S. De Young

University of Chicago Press, 2002

Extragalactic radio sources are among the most unusual and spectacular objects in the universe, with sizes in excess of millions of light years, radiated energies over ten times those of normal galaxies, and a unique morphology. They reveal some of the most dramatic physical events ever seen and provide essential clues to the basic evolutionary tracks followed by all galaxies and groups of galaxies.

In The Physics of Extragalactic Radio Sources, David De Young provides a clearly written overview of what is currently known about these objects. A unique feature of the book is De Young's emphasis on the physical processes associated with extragalactic radio sources: their evolution, their environment, and their use as probes to solve other astrophysical problems. He also makes extensive use of the large amount of data now available from observations at x-ray, optical, and radio wavelengths to illustrate his main points.
The Physics of Extragalactic Radio Sources will be a comprehensive introduction to the field for graduate students and a useful summary for astrophysicists.

The Space Station

A Personal Journey

Hans Mark

Duke University Press, 1987

This insider's account, a penetrating view of science policy and politics during two presidencies, captures the euphoria that characterized the space program in the late seventies and early eighties and furnishes an invaluable perspective on the Challenger tragedy and the future of the United States in space. President Reagan's approval of $8 billion for the construction of a permanently manned orbiting space station climaxed one of the most important political and technological debates in the history of the U.S. program in space.
In The Space Station the story of this debate is told by Hans mark, who had major roles in the development of the space shuttle from its beginnings in the sixties and who bore a primary responsibility for overseeing the space station project during the decisive years from 1981 to 1984. Mark's appointment to the post of deputy administrator of NASA capped a career devoted to the development and management of space technology—he served as director of NASA's Ames Research Center, then as under secretary and later secretary of the U.S. Air Force. Serving under both President Carter and President Reagan, mark is uniquely able to chronicle the intricate process by which the space shuttle became a reality and the space station an acknowledged goal of the American space effort.
A scientist by training, Mark's account of his career in the space program is the story of a personal dream as well as the story of a vast public enterprise whose human side is only now being fully appreciated.

Theory of Neutron Star Magnetospheres

F. Curtis Michel

University of Chicago Press, 1990

An incomparable reference for astrophysicists studying pulsars and other kinds of neutron stars, Theory of Neutron Star Magnetospheres sums up two decades of astrophysical research. It provides in one volume the most important findings to date on this topic, essential to astrophysicists faced with a huge and widely scattered literature.

F. Curtis Michel, who was among the first theorists to propose a neutron star model for radio pulsars, analyzes competing models of pulsars, radio emission models, winds and jets from pulsars, pulsating X-ray sources, gamma-ray burst sources, and other neutron-star driven phenomena. Although the book places primary emphasis on theoretical essentials, it also provides a considerable introduction to the observational data and its organization. Michel emphasizes the problems and uncertainties that have arisen in the research as well as the considerable progress that has been made to date.

Three Steps to the Universe

From the Sun to Black Holes to the Mystery of Dark Matter

David Garfinkle and Richard Garfinkle

University of Chicago Press, 2008

If scientists can’t touch the Sun, how do they know what it’s made of? And if we can’t see black holes, how can we be confident they exist? Gravitational physicist David Garfinkle and his brother, science fiction writer Richard Garfinkle, tackle these questions and more in Three Steps to the Universe, a tour through some of the most complex phenomena in the cosmos and an accessible exploration of how scientists acquire knowledge about the universe through observation, indirect detection, and theory.
 
The authors begin by inviting readers to step away from the Earth and reconsider our Sun. What we can directly observe of this star is limited to its surface, but with the advent of telescopes and spectroscopy, scientists know more than ever about its physical characteristics, origins, and projected lifetime. From the Sun, the authors journey further out into space to explore black holes. The Garfinkle brothers explain that our understanding of these astronomical oddities began in theory, and growing mathematical and physical evidence has unexpectedly supported it. From black holes, the authors lead us further into the unknown, to the dark matter and energy that pervade our universe, where science teeters on the edge of theory and discovery. Returning from the depths of space, the final section of the book brings the reader back down to Earth for a final look at the practice of science, ending with a practical guide to discerning real science from pseudoscience among the cacophony of print and online scientific sources. 

Three Steps to the Universe will reward anyone interested in learning more about the universe around us and shows how scientists uncover its mysteries.

Time Travel and Warp Drives

A Scientific Guide to Shortcuts through Time and Space

Allen Everett and Thomas Roman

University of Chicago Press, 2011

To see video demonstrations of key concepts from the book, please visit this website: http://www.press.uchicago.edu/sites/timewarp/

Sci-fi makes it look so easy. Receive a distress call from Alpha Centauri? No problem: punch the warp drive and you're there in minutes. Facing a catastrophe that can't be averted? Just pop back in the timestream and stop it before it starts. But for those of us not lucky enough to live in a science-fictional universe, are these ideas merely flights of fancy—or could it really be possible to travel through time or take shortcuts between stars?

Cutting-edge physics may not be able to answer those questions yet, but it does offer up some tantalizing possibilities. In Time Travel and Warp Drives, Allen Everett and Thomas A. Roman take readers on a clear, concise tour of our current understanding of the nature of time and space—and whether or not we might be able to bend them to our will. Using no math beyond high school algebra, the authors lay out an approachable explanation of Einstein's special relativity, then move through the fundamental differences between traveling forward and backward in time and the surprising theoretical connection between going back in time and traveling faster than the speed of light. They survey a variety of possible time machines and warp drives, including wormholes and warp bubbles, and, in a dizzyingly creative chapter, imagine the paradoxes that could plague a world where time travel was possible—killing your own grandfather is only one of them!

Written with a light touch and an irrepressible love of the fun of sci-fi scenarios—but firmly rooted in the most up-to-date science, Time Travel and Warp Drives will be a delightful discovery for any science buff or armchair chrononaut.

Combining the latest scientific advances with storytelling skills unmatched in the cosmos, an award-winning astrophysicist and popular writer leads us on a tour of some of the greatest mysteries of our universe.
 
In the constellation of Eridanus, there lurks a cosmic mystery: It’s as if something has taken a huge bite out of the universe. But what is the culprit? The hole in the universe is just one of many puzzles keeping cosmologists busy. Supermassive black holes, bubbles of nothingness gobbling up space, monster universes swallowing others—these and many other bizarre ideas are being pursued by scientists. Due to breathtaking progress in astronomy, the history of our universe is now better understood than the history of our own planet. But these advances have uncovered some startling riddles. In this electrifying new book, renowned cosmologist and author Paul Davies lucidly explains what we know about the cosmos and its enigmas, exploring the tantalizing—and sometimes terrifying—possibilities that lie before us.

As Davies guides us through the audacious research offering mind-bending solutions to these and other mysteries, he leads us up to the greatest outstanding conundrum of all: Why does the universe even exist in the first place? And how did a system of mindless, purposeless particles manage to bring forth conscious, thinking beings? Filled with wit and wonder, What’s Eating the Universe? is a dazzling tour of cosmic questions, sure to entertain, enchant, and inspire us all.
