Download or read book Sirius written by Jay B. Holberg and published by Springer Science & Business Media. This book was released on 2007-02-22 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book tells two stories. The first and most obvious is why the star known as Sirius has been regarded as an important fixture of the night sky by many civilizations and cultures since the beginnings of history. A second, but related, narrative is the prominent part that Sirius has played in how we came to achieve our current scientific understanding of the nature and fate of the stars. This is the first book to integrate the cultural history of Sirius with modern astrophysics in a way which provides a realistic view of how science progresses over time.

The United States Coast Pilot consists of a series of nautical books that cover a variety of information important to navigators of coastal and intracoastal waters and the Great Lakes. Issued in nine volumes, they contain supplemental information that is difficult to portray on a nautical chart. Topics in the Coast Pilot include channel descriptions, anchorages, bridge and cable clearances, currents, tide and water levels, prominent features, pilotage, towage, weather, ice conditions, wharf descriptions, dangers, routes, traffic separation schemes, small-craft facilities, and Federal regulations applicable to navigation. Coast Pilot 1 covers the coasts of Maine, New Hampshire, and part of Massachusetts, from West Quoddy Head in Maine to Provincetown in Massachusetts. Major ports are at Portsmouth, NH and Boston, MA. Coast Pilot 2 covers the Atlantic coast from Cape Cod to Sandy Hook, embracing part of the Massachusetts coast and all of the coasts of Rhode Island, Connecticut, and New York. Coast Pilot 3 covers the Atlantic coast from Sandy Hook to Cape Henry, including the New Jersey Coast, Delaware Bay, Philadelphia, the Delaware - Maryland - Virginia coast, and the Chesapeake Bay. Coast Pilot 4 covers the Atlantic coast of the United States from Cape Henry to Key West. Coast Pilot 5 covers the Gulf of Mexico from Key West, FL to the Rio Grande. This area is generally low and mostly sandy, presenting no marked natural features to the mariner approaching from seaward. so covers Puerto Rico and the Virgin Islands. Coast Pilot 6 covers the Great Lakes system, including Lakes Ontario, Erie, Huron, Michigan, and Superior, their connecting waters, and the St. Lawrence River. Coast Pilot 7 covers the rugged United States coast of California, Oregon and Washington, between Mexico on the south and Canadas British Columbia on the north. Coast Pilot 7 also includes Hawaii and other United States territories in the South Pacific. Coast Pilot 8 covers the panhandle section of Alaska between the south boundary and Cape Spencer. In this volume, general ocean coastline is only 250 nautical miles, but tidal shoreline totals 11,085 miles. Coast Pilot 9 deals with the Pacific and Arctic coasts of Alaska from Cape Spencer to the Beaufort Sea. General ocean coastline totals 5,520 nautical miles, and tidal shoreline totals 18,377 miles. Coast Pilot 10 consists of excerpts taken from other coast pilots with reference to the Intercoastal Waterway

Available in PDF, EPUB and Kindle. Book excerpt: The Sun is nowadays observed using di?erent techniques that provide an almost instantaneous 3-D map of its structure. Of particular interest is the studyofthevariabilityinthesolaroutputproducedbythedissipationofm- netic energy on di?erent spatial and temporal scales – the so-called magnetic activity. The 11-year cycle is the main feature describing this phenomenon. Apart from its intrinsic scienti?c interest, this topic is worth studying because of the interaction of such processes with the terrestrial environment. A ?eet of space and ground-based observatories are currently monitoring the behaviour of our star on a daily basis. However, solar activity varies not only on this decadal time-scale, as has been attested mainly through two methods: (a) records of the number of sunspots observed on the solar surface from 1610, and (b) the records of 14 10 cosmogenic isotopes, such as Cand Be, measured in tree-rings and i- cores, respectively. The study of the long-term behaviour of solar activity may be comp- mented by the study of historical accounts describing phenomena directly or indirectly related to solar activity. Numerous scienti?c and non-scienti?c d- uments have reported these events and we can make use of them as a proxy of solar activity in past times.

Download or read book The Lost Constellations written by John C. Barentine and published by Springer. This book was released on 2015-10-23 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Casual stargazers are familiar with many classical figures and asterisms composed of bright stars (e.g., Orion and the Plough), but this book reveals not just the constellations of today but those of yesteryear. The history of the human identification of constellations among the stars is explored through the stories of some influential celestial cartographers whose works determined whether new inventions survived. The history of how the modern set of 88 constellations was defined by the professional astronomy community is recounted, explaining how the constellations described in the book became permanently “extinct.” Dr. Barentine addresses why some figures were tried and discarded, and also directs observers to how those figures can still be picked out on a clear night if one knows where to look. These lost constellations are described in great detail using historical references, enabling observers to rediscover them on their own surveys of the sky. Treatment of the obsolete constellations as extant features of the night sky adds a new dimension to stargazing that merges history with the accessibility and immediacy of the night sky.

Download or read book Cataclysmic Cosmic Events and How to Observe Them written by Martin Mobberley and published by Springer Science & Business Media. This book was released on 2009-03-01 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Victorian era – or for non-British readers, the mid-to-late nineteenth century – amateur astronomy tended to center on Solar System objects. The Moon and planets, as well as bright comets, were the key objects of interest. The brighter variable stars were monitored, but photography was in its infancy and digital imaging lay a century in the future. Today, at the start of the twenty-first century, amateurs are better equipped than any professionals of the mid-twentieth century, let alone the nineteenth. An amateur equipped with a 30-cm telescope and a CCD camera can easily image objects below magnitude 20 and, from very dark sites, 22 or 23. Such limits would have been within the realm of the 100- and 200-inch reflectors on Mount Wilson and Mount Palomar in the 1950s, but no other observatories. However, even those telescopes took hours to reach such limits, and then the photographic plates had to be developed, fixed, and examined by eye. In the modern era digital images can be obtained in minutes and analyzed ‘on the fly’ while more images are being downloaded. Developments can be e-mailed to other interested amateurs in real time, during an observing session, so that when a cataclysmic event takes place amateurs worldwide know about it. As recently as the 1980s, even professional astronomers could only dream of such instantaneous communication and proc- sing ability.

Download or read book Celestial Sleuth written by Donald W. Olson and published by Springer Science & Business Media. This book was released on 2013-10-02 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: For a general audience interested in solving mysteries in art, history, and literature using the methods of science, 'forensic astronomy' is a thrilling new field of exploration. Astronomical calculations are the basis of the studies, which have the advantage of bringing to readers both evocative images and a better understanding of the skies. Weather facts, volcano studies, topography, tides, historical letters and diaries, famous paintings, military records, and the friendly assistance of experts in related fields add variety, depth, and interest to the work. The chosen topics are selected for their wide public recognition and intrigue, involving artists such as Vincent van Gogh, Claude Monet, Edvard Munch, and Ansel Adams; historical events such as the Battle of Marathon, the death of Julius Caesar, the American Revolution, and World War II; and literary authors such as Chaucer, Shakespeare, Joyce, and Mary Shelley. This book sets out to answer these mysteries indicated with the means and expertise of astronomy, opening the door to a richer experience of human culture and its relationship with nature. Each subject is carefully analyzed. As an example using the study of sky paintings by Vincent van Gogh, the analytical method would include: - computer calculations of historical skies above France in the 19th century - finding and quoting the clues found in translations of original letters by Van Gogh - making site visits to France to determine the precise locations when Van Gogh set up his easel and what celestial objects are depicted. For each historical event influenced by astronomy, there would be a different kind of mystery to be solved. As an example: - How can the phase of the Moon and time of moonrise help to explain a turning point of the American Civil War - the fatal wounding of Stonewall Jackson at Chancellorsville in 1863? For each literary reference to astronomy, it was determined which celestial objects were being described and making an argument that the author is describing an actual event. For example, what was the date of the moonlit scene when Mary Shelley first had the idea for her novel “Frankenstein?” These and more fun riddles will enchant and delight the fan of art and astronomy.

Download or read book The History of Mathematical Tables written by Martin Campbell-Kelly and published by OUP Oxford. This book was released on 2003-10-02 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The oldest known mathematical table was found in the ancient Sumerian city of Shuruppag in southern Iraq. Since then, tables have been an important feature of mathematical activity; table making and printed tabular matter are important precursors to modern computing and information processing. This book contains a series of articles summarising the technical, institutional and intellectual history of mathematical tables from earliest times until the late twentieth century. It covers mathematical tables (the most important computing aid for several hundred years until the 1960s), data tables (eg. Census tables), professional tables (eg. insurance tables), and spreadsheets - the most recent tabular innovation. The book is presented in a scholarly yet accessible way, making appropriate use of text boxes and illustrations. Each chapter has a frontispiece featuring a table along with a small illustration of the source where the table was first displayed. Most chapters have sidebars telling a short "story" or history relating to the chapter. The aim of this edited volume is to capture the history of tables through eleven chapters written by subject specialists. The contributors describe the various information processing techniques and artefacts whose unifying concept is "the mathematical table".

Download or read book Five Millennium Catalog of Solar Eclipses 1999 to 3000 written by Fred Espenak and published by . This book was released on 2021-07-30 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 5,000-year period from -1999 to +3000 (2000 BCE to 3000 CE), Earth will experience 11,898 eclipses of the Sun. The eclipses are distributed as follows: 4200 partial eclipses, 3956 annular eclipses, 3173 total eclipses, and 569 hybrid eclipses.The "Five Millennium Catalog of Solar Eclipses: -1999 to +3000" contains a catalog listing the date, eclipse type, and principal characteristics of every eclipse during this period. Tabulated data for each eclipse includes the catalog number, canon plate number, calendar date, Terrestrial Dynamical Time of greatest eclipse, ?T, lunation number, Saros number, eclipse type, Quincena Lunar Eclipse parameter, gamma, eclipse magnitude, geographic coordinates of greatest eclipse (latitude and longitude), and the circumstances at greatest eclipse (i.e., Sun altitude and azimuth, path width, and central line duration).The statistics of the solar eclipse distribution over 5,000 years are investigated in detail. This includes eclipse types by month and by century, eclipse frequency in the calendar year, extremes in eclipse magnitude for all eclipse types, maximum durations of total, annular, and hybrid eclipses, and eclipse duos (two eclipses within 30 days of each other).A discussion of the major cycles in the Moon's orbit and their role in the occurrence of solar eclipses is presented. These include the synodic, the anomalistic, and the draconic months.Finally, the periodicity of solar eclipses is investigated with particular attention to the Saros cycle. Tables list the start and end dates, number, and type of eclipses of every Saros series in progress during the 5,000-year period covered by the Five Millennium Canon.The Catalog serves as a supplement to the "Five Millennium Canon of Solar Eclipses" which contains a map of every eclipse. The Canon and the Catalog both use the same solar and lunar ephemerides as well as the same value of ?T. This 1-to-1 correspondence between them enhances the value of each. The researcher may now search, evaluate, and compare eclipses graphically (Canon) or textually (Catalog).
