The ability of storing, managing and giving access to the huge quantity of data collected by astronomical observatories is one of the major challenges of modern astronomy. At the same time, the growing complexity of data systems implies a change of concepts: the scientist has to manipulate data as well as information. Developments of the "World Wide Web" bring answers to these problems. The book presents a wide selection of databases, archives, data centres and information systems. Descriptions are included, together with their scientific context and motivations. This volume should prove a useful tool for astronomers, librarians, data specialists and computer engineers.
In their search for solutions to problems concerning the dynamics
of the Earth as a self-gravitating body, the authors have applied
the fundamentals found in their book "Jacobi Dynamics" (1987,
Reidel). First, satellite observations have shown that the Earth
does not remain in hydrostatic equilibrium, which forms the
physical basis of modern geodynamics. Secondly, satellite data have
established a relationship between the planet's polar moment of
inertia and the potential of the Earth's outer force field, which
proves the most basic point of Jacobi dynamics. This allowed the
authors to revise their derivation of the classical virial theorem,
introducing the concept of a volumetric force and volumetric
moment, and so to obtain a generalized virial theorem in the form
of Jacobi's equation.
The book highlights the personal and scientific struggles of Arthur Erich Haas (1884-1941), an Austrian Physicist from a wealthy Jewish middle-class family, whose remarkable accomplishments in a politically hostile but scientifically rewarding environment deserve greater recognition. Haas was a fellow student of both Lise Meitner and Erwin Schroedinger and was also one of the last doctoral students of Ludwig Boltzmann. Following Boltzmann's suicide, Haas was forced to submit a more independent doctoral thesis in which he postulated new approaches in early quantum theory, actually introducing the idea of the Bohr radius before Niels Bohr. It is the lost story of a trailblazer in the fields of quantum mechanics and cosmology, a herald of nuclear energy and applications of modern science. This biography of Haas is based on new and previously unpublished family records and archived material from the Vienna Academy of Science and the University of Notre Dame, which the author has collected over many years. From his analysis of the letters, documents, and photos that rested for nearly a century in family attics and academic archives, Michael Wiescher provides a unique and detailed insight into the life of a gifted Jewish physicist during the first half of the twentieth century. It also sheds light on the scientific developments and thinking of the time. It appeals not only to historians and physicists, but also general readers. All appreciate the record of Haas' interactions with many of the key figures who helped to found modern physics.
"Exceptionally absorbing and thrilling. ... Masterful." -Nature A "magnificent" (Scientific American), genre-defying narrative of the most ambitious science project ever conceived: NASA's deep space mission to Europa, the Jovian moon where might swim the first known alien life in our solar system In the spirit of Tom Wolfe and John McPhee, The Mission is an exuberant master class of creative nonfiction that reveals how a motley, determined few expanded the horizon of human achievement. When scientists discovered the first ocean beyond Earth, they had two big questions: "Is it habitable?" and "How do we get there?" To answer the first, they had to solve the second, and so began a vivacious team's twenty-year odyssey to mount a mission to Europa, the ocean moon of Jupiter. Standing in their way: NASA, fanatically consumed with landing robots on Mars; the White House, which never saw a science budget it couldn't cut; Congress, fixated on going to the moon or Mars-anywhere, really, to give astronauts something to do; rivals in academia, who wanted instead to go to Saturn; and even Jupiter itself, which guards Europa in a pulsing, rippling radi ation belt-a halo of death whose conditions are like those that follow a detonated thermonuclear bomb. The Mission is the Homeric, never-before-told story of modern space exploration, and a magnificent portrait of the inner lives of scientists who study the solar system's mysterious outer planets. David W. Brown chronicles the remarkable saga of how Europa was won, and what it takes to get things done-both down here, and up there.

In 1833 John Herschel sailed from London to Cape Town, southern Africa, to undertake (at his own expense) an astronomical exploration of the southern heavens, as well as a terrestrial exploration of the area around Cape Town. After his return to England in 1838, and as a result of his voyage, he was highly esteemed and became Britain's most recognized man of science. In 1847 his southern hemisphere astronomical observations were published as the Cape Results. The main argument of Ruskin's book is that Herschel's voyage and the publication of the Cape Results, in addition to their contemporary scientific importance, were also significant for nineteenth-century culture and politics. In this book it is demonstrated that the reason for Herschel's widespread cultural renown was the popular notion that his voyage to the Cape was a project aligned with the imperial ambitions of the British government. By leaving England for one of its colonies, and pursuing there a significant scientific project, Herschel was seen in the same light as other British men of science (like James Cook and Richard Lander) who had also undertaken voyages of exploration and discovery at the behest of their nation. It is then demonstrated that the production of the Cape Results, in part because of Herschel's status as Britain's scientific figurehead, was a significant political event. Herschel's decision to journey to the Cape for the purpose of surveying the southern heavens was of great significance to almost all of Britain and much of the continent. It is the purpose of this book to make a case for the scientific, cultural, and political significance of Herschel's Cape voyage and astronomical observations, as a means of demonstrating the relationship of scientific practice to broader aspects of imperial culture and politics in the nineteenth century.
This collection of essays on cultural astronomy celebrates the life and work of Clive Ruggles, Emeritus Professor of Archaeoastronomy at Leicester University. Taking their lead from Ruggles' work, the papers present new research focused on three core themes in cultural astronomy: methodology, case studies, and heritage. Through this framework, they show how the study of cultural astronomy has evolved over time and share new ideas to continue advancing the field. Ruggles' work in these areas has had a profound impact on the way that scholars approach evidence of the role of sky in both ancient and modern cultures. While the papers span many time periods and regions, they are closely connected by these three major themes, presenting methodological investigations of how we can approach archaeological, textual, and ethnographic evidence; describing detailed archaeoastronomical case studies; or stressing the importance of global heritage management. This work will appeal to researchers and scholars interested in the history and development of cultural astronomy.
This introduction to one of the liveliest and most popular fields in philosophy is written specifically for a beginning readership with no background in philosophy or science. Step-by-step analyses of the key arguments are provided and the philosophical heart of the issues is revealed without recourse to jargon, maths, or logical formulas. The book introduces Einstein's revolutionary ideas in a clear and simple way, along with the concepts and arguments of philosophers, both ancient and modern that have proved of lasting value. Specifically, the theories of the ancient Greek philosophers, Zeno, Euclid and Parmenides are considered alongside the ideas of Newton, Leibniz and Kant as well as the giants of twentieth-century physics, Einstein and Lorentz. The problems at the heart of the philosophy of space and time, such as change, motion, infinity, shape, and inflation, are examined and the seismic impact made by relativity theory and quantum theory is assessed in the light of the latest research. The writing is lucid and entertaining, allowing a beginning readership to grasp some difficult concepts while offering the more experienced reader a succinct and illuminating presentation of the state of the debate. "Space, Time and Einstein" shows the reader the excitement of scientific discovery and the beauty of theory in the search for answers to these fundamental questions.
This book is a comprehensive survey of the current state of knowledge about the dynamics and gravitational properties of cosmic strings treated in the idealized classical approximation as line singularities described by the Nambu-Goto action. The author's purpose is to provide a standard reference to all work that has been published since the mid-1970s and to link this work together in a single conceptual framework and a single notational formalism. A working knowledge of basic general relativity is assumed. The book will be essential reading for researchers and postgraduate students in mathematics, theoretical physics, and astronomy interested in cosmic strings.
Jacobus C. Kapteyn (1851-1922) was a Dutch astronomer who contributed heavily to major catalogs of star positions, such as the Cape Photographic Durchmusterung and the Harvard-Groningen Durchmusterung, and arranged extensive international collaboration through his Plan of Selected Areas. He contributed to the establishment of statistical astronomy and structure and dynamics of the Sidereal System. All aspects of Kapteyn's life are discussed, from his birth in Barneveld, the Netherlands, to his death in Amsterdam, and his entire resume of scientific achievements in between. Kapteyn had some conflicts with others in his field, especially after the world became divided on how to handle scientific contributions from Germany post-World War I. Both Kapteyn's struggles and achievements are written against the backdrop of both the historical context of the world at that time as well as the scientific one.
This book contains papers from a conference held to celebrate the 70th birthday of one of the world's foremost astronomical historians, Professor F. Richard Stephenson, the latest recipient of the American Astronomical Society's highest award for research in astronomical history, the LeRoy Doggett Prize. Reflecting Professor Stephenson's extensive research portfolio, this book brings together under one cover papers on four different areas of scholarship: applied historical astronomy (which Stephenson founded); Islamic astronomy; Oriental astronomy and amateur astronomy. These papers are penned by astronomers from Canada, China, England, France, Georgia, Iran, Japan, Lebanon, the Netherlands, Portugal, Thailand and the USA. Its diverse coverage represents a wide cross-section of the history of astronomy community. Under discussion are ways in which recent research using historical data has provided new insights into auroral and solar activity, supernovae and changes in the rotation rate of the Earth. It also presents readers with results of recent research on leading historical figures in Islamic and Oriental astronomy, and aspects of eighteenth and nineteenth century Australian, British, German and Portuguese amateur astronomy, including the fascinating 'amateur-turned-professional syndrome'.
Gravitational waves (GWs) are a hot topic and promise to play a
central role in astrophysics, cosmology, and theoretical physics.
Technological developments have led us to the brink of their direct
observation, which could become a reality in the coming years. The
direct observation of GWs will open an entirely new field: GW
astronomy. This is expected to bring a revolution in our knowledge
of the universe by allowing the observation of previously unseen
phenomena, such as the coalescence of compact objects (neutron
stars and black holes), the fall of stars into supermassive black
holes, stellar core collapses, big-bang relics, and the new and
unexpected.
"The Higgs Hunter's Guide" is a definitive and comprehensive guide to the physics of Higgs bosons. In particular, it discusses the extended Higgs sectors required by those recent theoretical approaches that go beyond the Standard Model, including supersymmetry and superstring-inspired models.
This is volume 4 of Planets, Stars and Stellar Systems, a six-volume compendium of modern astronomical research, covering subjects of key interest to the main fields of contemporary astronomy. This volume on Stellar Structure and Evolution edited by Martin A. Barstow presents accessible review chapters on Stellar Structure, Stellar Atmospheres, The Sun as a Star, Asteroseismology, Star Formation, Young Stellar Objects and Protostellar Disks, Brown Dwarfs, Evolution of Solar and Intermediate- Mass Stars, The Evolution of High Mass Stars, Stellar Activity, White Dwarf Stars, Black Holes and Neutron Stars, Binaries and Multiple Stellar Systems, Supernovae and Gamma-Ray Bursts, and Stellar Winds. All chapters of the handbook were written by practicing professionals. They include sufficient background material and references to the current literature to allow readers to learn enough about a specialty within astronomy, astrophysics and cosmology to get started on their own practical research projects. In the spirit of the series Stars and Stellar Systems published by Chicago University Press in the 1960s and 1970s, each chapter of Planets, Stars and Stellar Systems can stand on its own as a fundamental review of its respective sub-discipline, and each volume can be used as a textbook or recommended reference work for advanced undergraduate or postgraduate courses. Advanced students and professional astronomers in their roles as both lecturers and researchers will welcome Planets, Stars and Stellar Systems as a comprehensive and pedagogical reference work on astronomy, astrophysics and cosmology.
In this selection of studies, J.L. Mancha explores aspects of the development of medieval optics and astronomy, including some medieval antecedents of the work of early modern astronomers. The articles deal with Latin, Hebrew and Arabic texts, and the process of translation and transmission of knowledge, and focus on three main themes. First, the theory and astronomical use of the pinhole camera in the 12th and 13th centuries; the texts edited here contain a solution to the problem of the formation of images cast by light through triangular apertures, equivalent to Kepler's, a description of the correct procedure for measuring solar apparent diameters using finite apertures, and a derivation of the Sun's eccentricity from its apparent diameters at apogee and perigee. Second, the characteristics of the Latin and ProvenAal versions of Levi ben Gerson's astronomical work, composed in collaboration with the author, as well as his tables and canons for finding syzygies and the mathematical methods used in the derivation of parameters. Third, different aspects of the survival of homocentric astronomy in the Middle Ages, especially al-Bitruji's model for trepidation and the technique for calculating the hippopede resulting from Eudoxan couples.
Reflecting the results of twenty years; experience in the field of
multipurpose flights, this monograph includes the complex routes of
the trajectories of a number of bodies (e.g., space vehicles,
comets) in the solar system.
The strength of Professor Varisco's work lies in his combination of ethnographic fieldwork among highland Yemeni farmers with an extensive study of medieval Arabic manuscripts on folk astronomy and agriculture. The opening articles discuss the astronomical concept of the 'lunar stations' in pre-Islamic Arabia and as developed in Arab astronomy and almanac lore; subsequent ones expand on the significance of this for an agricultural society, and examine a unique corpus of Yemeni agricultural almanacs, dating from the Rasulid period (13th-15th centuries) to the present. A further theme is that of traditional Yemeni agriculture, with studies on irrigation practices, plough cultivation, sorghum production, and indigenous plant protection methods, as well as the use of star calendars for seasonal markers.
From an historical perspective, this text presents an entirely non- mathematical introduction to astronomy from the first endeavours of the ancients to the current developments in research enabled by cutting edge technological advances. Free of mathematics and complex graphs, the book nevertheless explains deep concepts of space and time, of relativity and quantum mechanics, and of origin and nature of the universe. It conveys not only the intrinsic fascination of the subject, but also the human side and the scientific method as practised by Kepler, defined and elucidated by Galileo, and then demonstrated by Newton.
Sitting still in a quiet room, you might just be able to convince yourself that nothing is moving. But air currents swirl about you. Blood rushes through your veins. The atoms in your chair jiggle furiously. And the planet you are on is whizzing through space 35 times faster than the speed of sound. In Zoom, Bob Berman takes a thrilling tour around the wondrous and myriad motions that shape every aspect of the universe. Spanning astronomy, geology, biology, meteorology and history, he explains how clouds stay aloft, how the earth's rotation curves a ball's flight, how a mosquito's familiar whine is tuned to a perfect A sharp, how the day gets longer every century, and much more.
Edwin Hubble: Mariner of the Nebulae is both the biography of an
extraordinary human being and the story of the greatest quest in
the history of astronomy since the Copernican revolution. The book
is a revealing portrait of scientific genius, an incisive engaging
history of ideas, and a shimmering evocation of what we see when
gazing at the stars. |
