Of all the portions of the universe we see in the sky, the most spectacular is the Sun. Our very own star, the Sun is ruler of the Solar System. When it is shining, it drowns out everything else. When clouds cover the Sun, the day is gloomy. At night, when the Sun is not overhead, the sky is dark. All the world depends on the Sun. Topics include sunspots, flares, prominences, the Sun's atmosphere, upcoming solar eclipses, and the Sun's vital importance to life on Earth.

"A new collection of seventeen science essays that once again demonstrate the profound knowledge and imagination which have become the hallmarks of Isaac Asimov's works. Here, Dr. Asimov explores such topics as: the farthest distance in the universe; why astrology is sheer nonsense; how eclipses occur and how they were predicted by the ancients; why antievolutionists should consider the chimpanzee; why the North Star keeps shifting, and how it proves that Bacon didn't write Shakespeare's plays; and why fusion, and not fission, is the only solution to the energy crisis. Each fascinating chapter in this new volume brings Dr. Asimov further toward his goal of explaining to everyone the wonders of the universe and of man." --

Published by Avon Books, 1983, this First Paperback Edition has 253 pages. Isaac Asimov was considered to be one of the big three authors who brought science fiction into the American households.

Astronomy is a fortunate science; it needs no embellishments, said the French savant Arago. So fascinating are its achievements that no special effort is needed to attract attention. Nonetheless, the science of the heavens is not only a collection of astonishing revelations and daring theories. Ordinary facts, things that happen, day by day, are its substance. Most laymen have, generally speaking, a rather hazy notion of this prosaic aspect of astronomy. They find it of little interest, for it is indeed hard to concentrate on what is always before the eye.Everyday happenings in the sky are the contents of this book, free from professional terminology with easy reading. Its purpose is to initiate the reader into the basic facts of astronomy. Ordinary facts with which you may be acquainted are couched here in unexpected paradoxes, or slanted from an odd and unexpected angle solely to excite the imagination and quicken your interest. The daily aspect of the science of the skies, its beginnings, not later findings that mainly form the contents of Astronomy for Entertainment. The purpose of the book is to initiate the reader into the basic facts of astronomy. Ordinary facts with which you may be acquainted are couched here in unexpected paradoxes, or slanted from an odd and unexpected angle. The theme is, as far as possible, free from "terminology" and technical paraphernalia that so often make the reader shy of books on astronomy.Books on popular science are often rebuked for not being sufficiently serious. In a way the rebuke is just, and support for it can be found (if one has in mind the exact natural sciences) in the tendency to avoid calculations in any shape or form. And yet the reader can really master his subject only by learning how to reckon, even though in a rudimentary fashion. True, he has taken care to present them in an easy form, well within the reach of all who have studied mathematics at school. It is his conviction that these exercises help not only retain the knowledge acquired; they are also a useful introduction to more serious reading.This book contains chapters relating to the Earth, the Moon, planets, stars and gravitation. The author has concentrated in the main on materials not usually discussed in works of this nature. Subjects omitted in the present book, will, he hopes, be treated in a second volume. The book, it should be said, makes no attempt to analyze in detail the rich content of modern astronomy.Unfortunately Y. Perelman never wrote the continuation he had planned for this book, as untimely death in war bound Leningrad in 1942 interrupted his labours.

Two world-renowned scientists present an audacious new vision of the cosmos that “steals the thunder from the Big Bang theory.” — Wall Street JournalThe Big Bang theory—widely regarded as the leading explanation for the origin of the universe—posits that space and time sprang into being about 14 billion years ago in a hot, expanding fireball of nearly infinite density. Over the last three decades the theory has been repeatedly revised to address such issues as how galaxies and stars first formed and why the expansion of the universe is speeding up today. Furthermore, an explanation has yet to be found for what caused the Big Bang in the first place.In Endless Universe , Paul J. Steinhardt and Neil Turok, both distinguished theoretical physicists, present a bold new cosmology. Steinhardt and Turok “contend that what we think of as the moment of creation was simply part of an infinite cycle of titanic collisions between our universe and a parallel world” ( Discover ). They recount the remarkable developments in astronomy, particle physics, and superstring theory that form the basis for their groundbreaking “Cyclic Universe” theory. According to this theory, the Big Bang was not the beginning of time but the bridge to a past filled with endlessly repeating cycles of evolution, each accompanied by the creation of new matter and the formation of new galaxies, stars, and planets.Endless Universe provides answers to longstanding problems with the Big Bang model, while offering a provocative new view of both the past and the future of the cosmos. It is a “theory that could solve the cosmic mystery” ( USA Today ).

A look up at the night sky reveals a treasury of wonders. Even to the naked eye, the Moon, stars, planets, the Milky Way and even a few star clusters and nebulae illuminate the heavens. For millennia, humans struggled to make sense of what's out there in the Universe, from all we can see to that which lies beyond the limits of even our most powerful telescopes. Beyond the Galaxy traces our journey from an ancient, Earth-centered Universe all the way to our modern, 21st century understanding of the cosmos. Touching on not only what we know but also how we know it, Ethan Siegel takes us to the very frontiers of modern astrophysics and cosmology, from the birth of our Universe to its ultimate fate, and everything in between.

X-ray astronomy is the prime available window on astrophysical compact objects: black holes, neutron stars and white dwarfs. In this book, the foremost experts in the field provide a comprehensive overview of the observations and astrophysics of these objects. This is a valuable reference for graduate students and active researchers.

McCrimmon, having gotten Grierson's attention, continued: "A breakthrough, you say? If it's in economics, at least it can't be dangerous. Nothing like gene engineering, laser beams, sex hormones or international relations. That's where we don't want any breakthroughs. " (Galbraith, 1. K. (1990) A Tenured Profes sor, Houghton Mifflin; Boston. ) To judge [astronomy] in this way [a narrow utilitarian point of view] demon strates not only how poor we are, but also how small, narrow, and indolent our minds are; it shows a disposition always to calculate the payolTbefore the work, a cold heart and a lack of feeling for everything that is great and honors man. One can unfortunately not deny that such a mode of thinking is not uncommon in our age, and I am convinced that this is closely connected with the catastro phes which have befallen many countries in recent times; do not mistake me, I do not talk of the general lack of concern for science, but of the source from which all this has come, of the tendency to everywhere look out for one's advan tage and to relate everything to one's physical well-being, of the indilTerence towards great ideas, ofthe aversion to any elTort which derives from pure enthu siasm: I believe that such attitudes, if they prevail, can be decisive in catas trophes of the kind we have experienced. [Gauss, K. F. : Astronomische An trittsvorlesung (cited from Buhler, W. K. (1981) Gauss: A Biographical Study, Springer: New York)].

In recent years a noticeable trend toward harmonizing the distinct worldviews of science and religion has become increasingly popular. Despite marked public interest, many leading scientists remain skeptical that there is much common ground between scientific knowledge and religious belief. Indeed, they are often antagonistic. Can an accommodation be reached after centuries of conflict?In this stimulating collection of articles on the subject, Paul Kurtz, with the assistance of Barry Karr and Ranjit Sandhu, have assembled the thoughts of scientists from various disciplines. Among the distinguished contributors are Sir Arthur C. Clarke (author of 2001: A Space Odyssey, and numerous other works of science fiction); Nobel Prize Laureate Steven Weinberg (professor of physics at the University of Texas at Austin); Neil deGrasse Tyson (Princeton University astrophysicist and director of the Hayden Planetarium); James Lovelock (creator of the Gaia hypothesis); Kendrick Frazier (editor of the Skeptical Inquirer); Steven Pinker (professor of psychology at MIT); Richard Dawkins (zoologist at Oxford University); Eugenie Scott (physical anthropologist and executive director of the National Center for Science Education); Owen Gingerich (professor of astronomy at Harvard University); Martin Gardner (prolific popular science writer); the late Richard Feynman (Nobel Prize-winning physicist) and Stephen Jay Gould (professor of geology at Harvard University); and many other eminent scientists and scholars.Among the topics discussed are the Big Bang and the origin of the universe, intelligent design and creationism versus evolution, the nature of the "soul," near-death experiences, communication with the dead, why people do or do not believe in God, and the relationship between religion and ethics.

In these three studies-Copernicus, Kepler, Borelli- which are brought together in this volume, it is not my intention to review the history of astronomy in the sixteenth and seventeenth centuries from Corperius to Newton, but only the history of the 'astronomical revolution', that is to say, the history of the evolution and transformation the key-concepts by means of which endeavors to reduce to order, of to save, phenomena-by clearly setting forth the facts that underlie and explain the chaos of sentient appearances.

"Astrobiology is an exciting interdisciplinary field that seeks to answer one of the most important and profound questions: Are we alone? In this volume, leading international experts explore the frontiers of astrobiology, investigating the latest research questions that will fascinate a wide interdisciplinary audience at all levels. What is the earliest evidence for life on Earth? Where are the most likely sites for life in the Solar System? Could life have evolved elsewhere in the Galaxy? What are the best strategies for detecting intelligent extraterrestrial life? How many habitable or Earth-like exoplanets are there? Progress in astrobiology over the past decade has been rapid and, with evidence accumulating that Mars once hosted standing bodies of liquid water, the discovery of over 500 exoplanets, and new insights into how life began on Earth, the scientific search for our origins and place in the cosmos continues. The book is based on a meeting at the Pontifical Academy of Sciences, which gathered leading researchers to present state-of-the-art reviews on their research and address topics at the forefront of astrobiology"--

This is the third in a series of volumes of essays by Steven Weinberg, the previous two having also been published by HUP (Facing Up in 2001, and Lake Views in 2010). Weinberg, recipient of the Nobel Prize (1979) with Abdus Shalam and Sheldon Glashow for their contributions to the electroweak unification theory, is well known not only for his groundbreaking work in physics, but also for his efforts in popularizing science and the history of science, and for his stances on various matters in politics, public policy, and religion. This volume, like the previous two, runs a wide gamut, from the cosmological to the personal. Specific topics include particle physics, quantum mechanics, astronomy, big science, the history of science, space flight, science funding, the limits of current knowledge, and several other subjects ranging from the art of discovery to being wrong. Nearly all of the work included here, again as with the previous two volumes, has been previously published. The author has added introductions to the volume as a whole and to each essay, putting the material in context and adding further explanation where necessary. He has also added a number of explanatory notes.--

Two Nobel Laureates present a systematic, comprehensive account of the theory, techniques, experimental data, and interpretation involved in the study of microwave spectroscopy—a subject relevant to nuclear physics, molecular structure, chemical kinetics, quantum electrodynamics, and astronomy.The material in this volume is discussed critically, systematically, and in the simplest form. The simplicity of the wording and mathematics makes most of the contents accessible to those with a very elementary knowledge of quantum mechanics and atomic physics. Although the treatment is continuously developed, each of the 18 chapters is self-contained. Nearly 200 tables and figures augment the text. Appendixes supply most of the background for research and interpretation of microwave spectra; they also contain extensive data on nuclear and molecular constants, including essentially all those determined by microwave techniques. "Equally suitable for use as a fundamental reference or advanced textbook." — U.S. Quarterly Book Review .

The exploration of the first billion years of the history of the Universe represents one of the great challenges of contemporary astrophysics. This book contains the worked out lectures given at the 36th Saas-Fee Advanced Course "First Light in the Universe" by three eminent scientists in the field: Abraham Loeb, Andrea Ferrara, and Richard Ellis. The formation of the first stars and black holes, the initial mass function, feedback effects, early dust formation, the cosmic star formation history, distant galaxies, cosmic reionisation and the cosmic infrared background are the main topics treated. This book contains an accessible and up-to-date review of the field and will be useful to graduate students of astronomy, cosmologists, physicists and researchers. The topic of this book is particularly timely, as many new important observational facilities are being built, for which "first light in the universe" is one of the main science drivers.

A Kabbalistic Universe is about how and why Existence came into being. It sets out the general scheme of the four Worlds of Emanation, Creation, Formation and Action and heir various archangelic, angelic, demonic and organic inhabitants. Drawing upon ancient, medieval and modern material this book brings the Kabbalistic tradition up to date so that the current generation can perceive what Existence is about and how they might play a conscious part in humanity's role of aiding God to behold God in the Mirror of Existence. This is a revised edition with additional graphics. These make the Divine principles involved more comprehensible. Once the terms and metaphysics are mastered, then new perceptions are possible regarding not only the structure and dynamics of Existence but also the workings of the angelics and demonics, Nature and the process of human evolution and its purpose.
