This work presents a study of methods useful for modeling and understanding dynamical systems in the Galaxy. A natural coordinate system for the study of dynamical systems is the angle-action coordinate system. New methods for the approximation of the action-angle variables in general potentials are presented and discussed. These new tools are applied to the construction of dynamical models for two of the Galaxy’s components: tidal streams and the Galactic disc. Tidal streams are remnants of tidally stripped satellites in the Milky Way that experience the effects of the large scale structure of the Galactic gravitational potential, while the Galactic disc provides insights into the nature of the Galaxy near the Sun.

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.
Arditti’s approachable work covers the all the details of design, siting and construction – once a basic type has been decided upon. It is written in a way that is equally applicable to the USA and UK (where there are slightly different building regulations) and deals with matters that are basic to building and commissioning any amateur observatory. Uniquely, David Arditti also considers the aesthetics of amateur observatories – fitting them in with family and neighbors, and maybe disguising them as more common garden buildings if necessary.
This is the first non-technical book on spectroscopy written specifically for practical amateur astronomers. It includes all the science necessary for a qualitative understanding of stellar spectra, but avoids a mathematical treatment which would alienate many of its intended readers. Any amateur astronomer who carries out observational spectroscopy and who wants a non-technical account of the physical processes which determine the intensity and profile morphology of lines in stellar spectra will find this is the only book written specially for them.
The study of dust in the universe is an exciting area in current astronomy. Dust formed during an earlier epoch could be different from that formed at a later time, but the nature and composition of dust is not presently understood in its entirety. The comprehensive study presented in this book provides a much needed critical analysis of different types of dust in the universe. The information derived from presolar grains from comets, meteorites and interplanetary dust particles as well as the relevant laboratory studies are discussed.
Reconstructs a theoretic parent cosmology that underlies ancient religion • Shows how this parent cosmology provided the conceptual origins of written language • Uses techniques of comparative cosmology to synchronize the creation traditions of the Dogon, ancient Egyptians, and ancient Buddhists • Applies the signature elements of this parent cosmology to explore and interpret the creation tradition of a present-day Tibetan/Chinese tribe called the Na-Khi–the keepers of the world’s last surviving hieroglyphic language Great thinkers and researchers such as Carl Jung have acknowledged the many broad similarities that exist between the myths and symbols of ancient cultures.
Isaac Newton’s Scientific Method examines Newton’s argument for universal gravity and his application of it to resolve the problem of deciding between geocentric and heliocentric world systems by measuring masses of the sun and planets. William L. Harper suggests that Newton’s inferences from phenomena realize an ideal of empirical success that is richer than prediction. Any theory that can achieve this rich sort of empirical success must not only be able to predict the phenomena it purports to explain, but also have those phenomena accurately measure the parameters which explain them.

Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system’s origins, and someday could even serve as stepping-stones for space exploration. In this book, Donald Yeomans introduces readers to the science of near-Earth objects–its history, applications, and ongoing quest to find near-Earth objects before they find us.I
Is our universe dying? Could there be other universes?In Parallel Worlds, world-renowned physicist and bestselling author Michio Kaku—an author who “has a knack for bringing the most ethereal ideas down to earth” (Wall Street Journal)—takes readers on a fascinating tour of cosmology, M-theory, and its implications for the fate of the universe.In his first book of physics since Hyperspace, Michio Kaku begins by describing the extraordinary advances that have transformed cosmology over the last century, and particularly over the last decade, forcing scientists around the world to rethink our understanding of the birth of the universe, and its ultimate fate.
Most elements are synthesized, or “cooked”, by thermonuclear reactions in stars. The newly formed elements are released into the interstellar medium during a star′s lifetime, and are subsequently incorporated into a new generation of stars, into the planets that form around the stars, and into the life forms that originate on the planets. Moreover, the energy we depend on for life originates from nuclear reactions that occur at the center of the Sun. Synthesis of the elements and nuclear energy production in stars are the topics of nuclear astrophysics, which is the subject of this book.
Vorwort der Autoren Nachdem wir vor drei Jahren Texte und Bilder vom Hubble-Weltraumteleskop zusammengetragen hatten, um aus der Fülle der Entdeckungen, Reportagen und Bilder einen illustrierten und gut lesbaren Text zu formulieren, konnten wir schließlich mit dem Resultat unserer Bemühungen einigermaßen zufrieden sein. Zwar war uns die Entwicklung wieder etwas davongeeilt, aber wir hatten versucht, alles zu berücksichtigen, was für den Leser des Jahres 1995 interessant und aktuell sein konnte1 • ln der Folge erschienen dann mehr oder weniger aktualisierte Ausgaben unseres Buches in englischer, französischer und japanischer Sprache, und überall fand der Band wohlwollendes Interesse.
High-performance CCD cameras have opened up an exciting new window on the Universe for amateur astronomers. This book provides a complete, self-contained guide to choosing and using CCD cameras. We start with a no-nonsense introduction to how a CCD camera works and just what determines its performance. We are then shown how to use a CCD camera and calibrate accurately the images we obtain. A clear review is then provided of the software available for visualising, analysing and processing digital images.
Did you know that scientists are beginning to think that the sun is safer than sunscreen? That whenever we see the sun on the horizon, it’s actually a phantom image because the sun has already set? That career pilots have a one percent higher incidence of cancer because of their time in the sky? Or that the sun’s unusual dormancy is causing our climate to be cooler than it otherwise would be?
In 2000, Martin Bojowald, then a twenty-seven-year-old post-doc at Pennsylvania State University, used a relatively new theory called loop quantum gravity—a cunning combination of Einstein’s theory of gravity with quantum mechanics—to create a simple model of the universe. Loop quantum cosmology was born, and with it, a theory that managed to do something even Einstein’s general theory of relativity had failed to do—illuminate the very birth of the universe.Ever since, loop quantum cosmology, or LQC, has been tantalizing physicists with the idea that our universe could conceivably have emerged from the collapse of a previous one.
In The Goldilocks Enigma, Paul Davies embarks on a comprehensive examination of current theories as to why the universe is so finely tuned, so astonishingly "just right". Davies considers a raft of answers to the book’s central question. He tells the whole story in a clear, well-paced manner that rivets the attention while boggling the mind.
As mass air transport shrinks the world and requires airport complexes large enough to be regarded as self-contained cities, this book argues that airspace – that transitional area stretching from terminal to terminal, across time zones or between the check-in desk and the baggage carousel – must be regarded as a discrete destination on any map of our age.At the hub of this exclusive enclave, which rises from the runway to an altitude of several thousand feet and which calmly accommodates the dangers of take-off and landing procedures, lies the airport – the concrete manifestation of airspace.
An accessible exposition of gravitation theory and celestial mechanics, this classic, oft-cited work was written by a distinguished Soviet astronomer. It explains with exceptional clarity the methods used by physicists in studying celestial phenomena.A historical introduction explains the Ptolemaic view of planetary motion and its displacement by the studies of Copernicus, Kepler, and Newton. Succeeding chapters examine the making of celestial observations and measurements and explain such central concepts as the ecliptic, the orbital plane, the two- and three-body problems, and perturbed motion.
