Originally published in 1942, this book discusses an emerging physical science that brought with it a fresh message as to the fundamental nature of the world, and of the possibilities of human free will in particular. The aim of the book is to explore that territory, which forms a borderland between physics and philosophy. The author seeks to estimate the philosophical significance of physical developments, and the interest of his enquiry extends far beyond technical physics and philosophy. Some of the questions raised touch everyday human life closely: can we have knowledge of the world outside us other than that what we can gain by observation and experiment? Is the world spiritual and psychological or material in its ultimate essence; is it better likened to a thought or to a machine? Are we endowed with free will, or are we part of a vast machine that must follow its course until it finally runs down?

Problems of Cosmogony and Stellar Dynamics is a theoretical prelude to Jeans's later and more mature work on the subject, Astronomy and Cosmogony. The impetus for publishing his theories on the behaviour of rotating masses, and on general dynamical theory, was the 1917 Adams Prize on the 'rotating and gravitating fluid mass'. Jeans won the prize with the core text of this volume. Enlarging on that work, and utilising the burgeoning results of astronomy, as well as the author's bolder theoretical conjectures, this book became a solid foundation for substantial progress in cosmology.

Sir James Jeans has used his remarkable gifts of exposition to set out all that is relevant in the science of acoustics to the art of music. He offers a simple but precise account (illustrated with well-chosen photographs and diagrams) of the anatomical origin and workings of the human ear; the nature of sound vibrations; simple tones and complex sounds; the principles and operation of musical instruments; harmony and the musical scale; the effects of music on men and animals; and the practical problems of acoustical design. Scientists who appreciate music, musicians with an interest in science and laymen who care for both, will thoroughly enjoy this book.

Through Space and Time is based upon the 1933 Christmas Lectures that James Jeans gave at the Royal Institution, London. Intended to appeal to a wide readership and presenting a broad understanding of the Earth, solar system and the universe, the book begins its journey with the history, structure and main features of our planet, and ends in the vast expanses of space among the nebulae.

Based on the recent NATO Advanced Study Institute "Chaotic Worlds: From Order to Disorder in Gravitational N-Body Dynamical Systems", this state of the art textbook, written by internationally renowned experts, provides an invaluable reference volume for all students and researchers in gravitational n-body systems. The contributions are especially designed to give a systematic development from the fundamental mathematics which underpin modern studies of ordered and chaotic behaviour in n-body dynamics to their application to real motion in planetary systems. This volume presents an up-to-date synoptic view of the subject.

In a novel reading of Shakespeare's plays, this book addresses an observation first made many decades ago, that Shakespeare appears to neglect the intellectual upheavals that astronomy brought about in his lifetime. The author examines temporal, situational, and verbal anomalies in Hamlet and other plays using hermeneutic-dialectic methodology, and finds a consistent pattern of interpretation that is compatible with the history of astronomy and with the development of modern cosmology. He also demonstrates how Shakespeare takes into account beliefs about the nature of the heavens from the time of Pythagoras up to and including discoveries and theories in the first decade of the seventeenth century. The book makes the case that, as in many other fields, Shakespeare's celestial knowledge is far beyond what was commonly known at the time. Students and teachers interested in Shakespeare's alleged indifference towards, or ignorance of, the celestial sciences will find this book illuminating, as will historians of science and scholars whose work focuses on epistemology and its relationship to the canon, and on how Shakespeare acquired the data that his plays deliver.

This book describes the complexity of impact hazards associated with asteroids and comets. The challenge in this regard lies in the heterogeneous nature of these bodies that endanger our planet, which is why we are conducting new experiments to better understand their unique physicochemical properties. Several generations of astronomers have tracked and mapped the orbits of asteroids and comets over the past few centuries, and telescopic surveys have only begun to discover "new" interstellar objects. In addition, cutting-edge software allow our computers to combine the orbits of these elusive bodies to study how they evolve over time and seek to match asteroid complexes as fragments of asteroidal and cometary disruptions. Impact hazards represent one of the greatest threats to the survival of human beings in the medium term. Geological studies show that the stratigraphic record holds clear geological evidence of these rare but transcendental encounters in the history of life on our planet. The study and quantification of past catastrophes can give us clues to face future challenges in the form of potential impacts. Further, it would be illogical to assume that Earth's interaction with space is limited to major impacts. Every night, Earth is struck by millions of particles, and dozens of meteor showers occur around the globe every year. The study of lake and ocean sediments reveals the magnitude of the continuous contribution of interplanetary matter reaching Earth: roughly 100,000 tons per year. Accordingly, the goal of this book is to underscore the need for society-wide awareness of the dangers associated with asteroid and comet impacts, on the basis of scientific evidence and with no intention of sparking alarmism. After all, we ourselves may only be the fruit of an opportunity given to mammals sixty-five million years ago to evolve after the conflagration that would be the downfall of the dinosaurs. If we have learned to read Earth's geological history, we should consider ourselves a very fortunate species, and its teachings should equip us to face this problem. The also book emphasizes the role of space missions to gain insights on these bodies, particularly describing the relevance of the DART (NASA) and Hera (ESA) missions to deflect and study Dimorphos, respectively, the small satellite of the Didymos binary asteroid.

A commentary on the astronomical references of holy scripture. Facsimile reprint of the first edition, including index and 34 illustrations.

This book is a superposition of two distinct narratives: the first is historical, discussing the evolution of astronomical knowledge since the dawn of civilizations; the second is scientific, conveying mathematical and physical content of each advancement. Great scientists of antiquity, Middle Ages and modern times until the 18th century, are presented along with their discoveries, through short biographies and anecdotes. Special care is taken to explain their achievements using mathematical and physical concepts of their time, with modern perspective added only when ancient methodology is too cumbersome or its language hardly understandable to contemporary readers.The book conveys a lot of astronomical facts and data in a pleasant and accessible manner. Almost all findings and discoveries made in ancient times are followed by simple mathematical exercises using basic knowledge, so that the reader can check the assertions himself. The book contains a lot of inedited illustrations. Geometrical schemes are given extra attention to make the examples clear and understandable. The language is simple and accessible to the young audience.

A revealing look at the parallel mythologies behind the colonization of Earth and space-and a bold vision for a more equitable, responsible future both on and beyond our planet. As environmental, political, and public health crises multiply on Earth, we are also at the dawn of a new space race in which governments team up with celebrity billionaires to exploit the cosmos for human gain. The best-known of these pioneers are selling different visions of the future: while Elon Musk and SpaceX seek to establish a human presence on Mars, Jeff Bezos and Blue Origin work toward moving millions of earthlings into rotating near-Earth habitats. Despite these distinctions, these two billionaires share a core utopian project: the salvation of humanity through the exploitation of space. In Astrotopia, philosopher of science and religion Mary-Jane Rubenstein pulls back the curtain on the not-so-new myths these space barons are peddling, like growth without limit, energy without guilt, and salvation in a brand-new world. As Rubenstein reveals, we have already seen the destructive effects of this frontier zealotry in the centuries-long history of European colonialism. Much like the imperial project on Earth, this renewed effort to conquer space is presented as a religious calling: in the face of a coming apocalypse, some very wealthy messiahs are offering an other-worldly escape to a chosen few. But Rubenstein does more than expose the values of capitalist technoscience as the product of bad mythologies. She offers a vision of exploring space without reproducing the atrocities of earthly colonialism, encouraging us to find and even make stories that put cosmic caretaking over profiteering.

In their latest book, Edmund O'Sullivan and Marilyn Taylor highlight the pedagogical practices that foster transformation from our current way of thinking about our place in the world to an underlying ecological way of seeing and acting. Learning Towards Ecological Consciousness offers the reader a selection of transformative practices that demonstrate, in specific contexts, the complex journey and contextual conditions that move us forward towards a deeper realization that we are part of the world around us, holding a greater promise for deeper ecological awareness. To this end, thirteen chapters offer a rich array of practices in diverse life settings--educational environments, communities and workplaces and personal relationships. Contributors and their material represent a range of cultures, work setting and professions. The aspect of O'Sullivan and Taylor's new book that distinguishes it from other books in the field is its exploration of how consciousness can be transformed through practices, experience and action.

In their approach to Earth dynamics the authors consider the fundamentals of Jacobi Dynamics (1987, Reidel) for two reasons. First, because satellite observations have proved that the Earth does not stay in hydrostatic equilibrium, which is the physical basis of today's treatment of geodynamics. And secondly, because satellite data have revealed a relationship between gravitational moments and the potential of the Earth's outer force field (potential energy), which is the basis of Jacobi Dynamics. This has also enabled the authors to come back to the derivation of the classical virial theorem and, after introducing the volumetric forces and moments, to obtain a generalized virial theorem in the form of Jacobi's equation. Thus a physical explanation and rigorous solution was found for the famous Jacobi's equation, where the measure of the matter interaction is the energy. The main dynamical effects which become understandable by that solution can be summarized as follows: * the kinetic energy of oscillation of the interacting particles which explains the physical meaning and nature of the gravitation forces; * separation of the shell's rotation of a self-gravitating body with respect to the mass density; difference in angular velocities of the shell rotation; * continuity in changing the potential of the outer gravitational force field together with changes in density distribution of the interacting masses (volumetric center of masses); * the nature of the precession of the Earth, the Moon and satellites; the nature of the rotating body's magnetic field and the generation of the planet's electromagnetic field. As a final result, the creation of the bodies in the Solar System having different orbits was discussed. This result is based on the discovery that all the averaged orbital velocities of the bodies in the Solar System and the Sun itself are equal to the first cosmic velocities of their proto-parents during the evolution of their redistributed mass density. Audience The work is a logical continuation of the book Jacobi Dynamics and is intended for researchers, teachers and students engaged in theoretical and experimental research in various branches of astronomy (astrophysics, celestial mechanics and stellar dynamics and radiophysics), geophysics (physics and dynamics of the Earth's body, atmosphere and oceans), planetology and cosmogony, and for students of celestial, statistical, quantum and relativistic mechanics and hydrodynamics.

We humans are collectively driven by a powerful - yet not fully explained - instinct to understand. We would like to see everything established, proven, laid bare. The more important an issue, the more we desire to see it clarified, stripped of all secrets, all shades of gray. What could be more important than to understand the Universe and ourselves as a part of it? To find a window onto our origin and our destiny? This book examines how far our modern cosmological theories - with their sometimes audacious models, such as inflation, cyclic histories, quantum creation, parallel universes - can take us towards answering these questions. Can such theories lead us to ultimate truths, leaving nothing unexplained? Last, but not least, Heller addresses the thorny problem of why and whether we should expect to find theories with all-encompassing explicative power.

The Adriatic Meetings have traditionally been conferences on the most - vanced status of science. They are one of the very few conferences in physics aiming at a very broad participation of young and experienced researchers with di?erent backgrounds in particle physics. Particle physics has grown into a highly multi-faceted discipline over the sixty years of its existence, mainly because of two reasons: Particle physics as an experimental science is in need of large-scale laboratory set-ups, involving typically collaborations of several hundreds or even thousands of researchers and technicians with the most diverse expertise. This forces particle physics, being one of the most fundamental dis- plines of physics, to maintain a constant interchange and contact with other disciplines, notably solid-state physics and laser physics, cosmology and - trophysics, mathematical physics and mathematics. Since the expertise necessary in doing research in particle physics has become tremendously demanding in the last years, the ?eld tends to organize purely expert conferences, meetings and summer schools, such as for detector development, for astroparticle physics or for string theory. TheAdriaticMeetingthroughitsentirehistoryhasbeenaplaceforest- lishing exchange between theory and experiment. The 9th Adriatic Meeting successfully continued this tradition and even intensi?ed the cross-discipline communication by establishing new contacts between the community of c- mologists and of particle physicists. The exchange between theorists and - perimentalists was impressively intensive and will certainly have a lasting e?ect on several research projects of the European and world-wide physics community.

The reader will find in this volume the Proceedings of the NATO Advanced Study Institute held in Cortina d' Ampezzo, Italy, between July 25 and August 6, 1993, under the title From Newton to Chaos: Modem Techniques for Understanding and Coping With Chaos inN-Body Dynamical Systems. This institute was the latest in a series of meetings held every three years from 1972 to 1990 in dynamical astronomy, theoretical mechanics and celestial mechanics. The proceedings from these institutes have been well-received in the international community of research workers in these disciplines. The present institute was well attended with 15 series of lectures being given by invited speakers: in addition some 40 presentations were made by the other participants. The majority of these contributions are included in these proceedings. The all-pervading influence of chaos in dynamical systems (of even a few variables) has now been universally recognised by researchers, a recognition forced on us by our ability, using powerful computer hardware and software, to tackle dynamical problems that until twenty-five years ago were intractable. Doubtless it was felt by many that these new techniques provided a break-through in celestial mechanics and its related disciplines. And so they were.

Deep Impact, or at least part of the flight system, is designed to crash into comet 9P/Tempel 1. This bold mission design enables cometary researchers to peer into the cometary nucleus, analyzing the excavated material with its imagers and spectrometers. The book describes the mission, its objectives, expected results, payload, and data products in articles written by those most closely involved. This mission has the potential of revolutionizing our understanding of the cometary nucleus.

Three years ago the Reports on Astronomy were for the first time published in three separate parts whereby related astronomical topics were collected in one volume and each volume was kept to a size of no more than about 250 pages. The a m was to facilitate a wider distribution of individual volumes among astronomers and other scientists interested in specific subjects of astronomy. The same system was adopted for the present volume A of the IAU Transactions which covers the activities in astronomical research from January 1976 to December 1978. The Commission Presidents were invited to restrict their reports, to present a selection of the most important developments in the field of astronomy covered by their Commission, and to avoid overlaps with other Commission reports. As a re sult of the restriction in the number of pages some Commissions presen.t a large, concentrated list of references with little discussion, whereas others review some of the most exciting recent research developments in their subject. The distribution of the Commission Reports into the three parts of volume XVII A is as follows: VOL. XVII A PART 1 commission 4. Ephemerides 5. Documentation 6. Astronomical Telegrams " 7. Celestial Hechanics " 9. Instruments and Techniques 14. Fundamental Spectroscopic Data " 15. Physical Study of Cornets, Hinor Planets and Meteorites 16.
