Book excerpt: How to predict and calculate the positions of stars, planets, the sun, the moon, and satellites using a personal computer and high school mathematics. Our knowledge of the universe is expanding rapidly, as space probes launched decades ago begin to send information back to earth. There has never been a better time to learn about how planets, stars, and satellites move through the heavens. This book is for amateur astronomers who want to move beyond pictures of constellations in star guides and solve the mysteries of a starry night. It is a book for readers who have wondered, for example, where Saturn will appear in the night sky, when the sun will rise and set, or how long the space station will be over their location. In Celestial Calculations, J. L. Lawrence shows readers how to find the answers to these and other astronomy questions with only a personal computer and high school math. Using an easy-to-follow step-by-step approach, Lawrence explains what calculations are required, why they are needed, and how they all fit together. Lawrence begins with basic principles: unit of measure conversions, time conversions, and coordinate systems. He combines these concepts into a computer program that can calculate the location of a star, and uses the same methods for predicting the locations of the sun, moon, and planets. He then shows how to use these methods for locating the many satellites we have sent into orbit. Finally, he describes a variety of resources and tools available to the amateur astronomer, including star charts and astronomical tables. Diagrams illustrate the major concepts, and computer programs that implement the algorithms are included. Photographs of actual celestial objects accompany the text, and interesting astronomical facts are interspersed throughout. Source code (in Python 3, JAVA, and Visual Basic) and executables for all the programs and examples presented in the book are available for download at https://CelestialCalculations.github.io.

Download or read book Cold Case Christianity written by J. Warner Wallace and published by David C Cook. This book was released on 2013-01-01 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by an L. A. County homicide detective and former atheist, Cold-Case Christianity examines the claims of the New Testament using the skills and strategies of a hard-to-convince criminal investigator. Christianity could be defined as a “cold case”: it makes a claim about an event from the distant past for which there is little forensic evidence. In Cold-Case Christianity, J. Warner Wallace uses his nationally recognized skills as a homicide detective to look at the evidence and eyewitnesses behind Christian beliefs. Including gripping stories from his career and the visual techniques he developed in the courtroom, Wallace uses illustration to examine the powerful evidence that validates the claims of Christianity. A unique apologetic that speaks to readers’ intense interest in detective stories, Cold-Case Christianity inspires readers to have confidence in Christ as it prepares them to articulate the case for Christianity.

Download or read book Interferometry and Synthesis in Radio Astronomy written by A. Richard Thompson and published by Springer. This book was released on 2017-02-22 with total page 910 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY-NC 4.0 license. The third edition of this indispensable book in radio interferometry provides extensive updates to the second edition, including results and technical advances from the past decade; discussion of arrays that now span the full range of the radio part of the electromagnetic spectrum observable from the ground, 10 MHz to 1 THz; an analysis of factors that affect array speed; and an expanded discussion of digital signal-processing techniques and of scintillation phenomena and the effects of atmospheric water vapor on image distortion, among many other topics. With its comprehensiveness and detailed exposition of all aspects of the theory and practice of radio interferometry and synthesis imaging, this book has established itself as a standard reference in the field. It begins with an overview of the basic principles of radio astronomy, a short history of the development of radio interferometry, and an elementary discussion of the operation of an interferometer. From this foundation, it delves into the underlying relationships of interferometry, sets forth the coordinate systems and parameters to describe synthesis imaging, and examines configurations of antennas for multielement synthesis arrays. Various aspects of the design and response of receiving systems are discussed, as well as the special requirements of very-long-baseline interferometry (VLBI), image reconstruction, and recent developments in image enhancement techniques and astrometric observations. Also discussed are propagation effects in the media between the source and the observer, and radio interference, factors that limit performance. Related techniques are introduced, including intensity interferometry, optical interferometry, lunar occultations, tracking of satellites in Earth orbit, interferometry for remote Earth sensing, and holographic measurements of antenna surfaces. This book will benefit anyone who is interested in radio interferometry techniques for astronomy, astrometry, geodesy, or electrical engineering.

Download or read book Astronomical and Astrophysical Objectives of Sub Milliarcsecond Optical Astrometry written by Erik Høg and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astrometry is on the threshold of great changes due to the fact that this decade, alone, is witnessing an improvement of stellar positions equivalent to the total improvement of the previous two centuries. The Hipparcos Satellite has concluded its observations, and the catalog is in preparation. Preliminary results assure that the Hipparcos catalog will provide positions, parallaxes and annual proper motions for over 100,000 stars with accuracies of 1.5 milliarcseconds. In addition, the Tycho catalog will provide positions of about 30 milliarcseconds accuracy for over 1 million stars, and annual proper motions with 3 milliarcsecond accuracy will subsequently be ob tained by means of first epoch positions from the Astrographic Catalog. Optical interferometers on the ground are beginning operation, and these instruments can provide observational accuracies of approximately one milliarcsecond. Also, the traditional reference frame based on the Fun damental Catalog of bright stars is being replaced by the extragalactic ref erence frame, based on radio sources with accuracies of one milliarcsecond. Thus, astrometry will change from a fundamental reference frame defined in terms of the dynamical reference frame of the solar system with accuracies of 100 milliarcseconds to a space-fixed, extragalactic reference frame with accuracies of one milliarcsecond. Future astrometric observations should be in the 1 -100 milliarcsecond accuracy range. There are a number of concepts for future astrometric instruments in space. Most of these can provide sub-milliarcsecond astrometric accuracies.

Available in PDF, EPUB and Kindle. Book excerpt: An authoritative introduction to the fascinating topic of archaeoastronomy—ancient peoples' understanding and use of the skies. Ancient Astronomy: An Encyclopedia of Cosmologies and Myth draws on archaeological evidence and oral traditions to reveal how prehistoric humans perceived the skies and celestial phenomena. With over 200 entries, it offers a number of ways to approach ancient astronomy, from key examples and case studies worldwide (Stonehenge; Mexican and Egyptian pyramids; Chaco Canyon, New Mexico; the Nazca lines in Peru) to general themes (cosmologies, calendars, ancient ideas of space and time, origin myths), to fundamental concepts and methods (how the sky has changed over the centuries, how to survey a site), and to the field's most frequently asked questions (How did ancient peoples navigate the ocean using the stars? How does astrology relate to ancient astronomy? Can ancient sites be dated astronomically?) By revealing the astronomical significance of some of the world's most famous ancient landmarks and enduring myths and by showing how different themes and concepts are connected, Ancient Astronomy: An Encyclopedia of Cosmologies and Myth brings a unique authoritative perspective to an area too often left to speculation and sensationalism.

Available in PDF, EPUB and Kindle. Book excerpt: John Kretschmer is sailing's practical philosopher – as much a doer as a thinker. And that is the overarching theme of this chronicle of a sailing life. Often amusing, sometimes poignant, occasionally terrifying but always inspiring, his deeply personal account is a welcome reminder of the good life waiting at sea. With hundreds of thousands of nautical miles under his keel, John's adventures have taken him several times around the world, with challenging crossings of the Atlantic and the Pacific, a narrow escape from a coup in Yemen, an unlikely deliverance from a coral reef off Belize as well as more serene, introspective passages where trade winds are blowing and stories are flowing. His crew has included CEOs, actors, writers, teachers, kids – in essence, everyone. John's narrative is interwoven with practical tips and advice in seamanship, but also, and just as importantly, his hard-won insights about making the most of our lives. He truly believes we find out who we really are, and what we are capable of, far from the shackles of land, when we find a place where time changes shape – days may merge into one another, but minutes are memorable. To live adventurously is to live more fully, and that is the life John Kretschmer continues to live. In this book he shares his simple profundities that will inspire those who live to sail, and those seeking something more rewarding from life.
