PDF-(READ)-Greek Astronomy (Dover Books on Astronomy)

Astronomy as a science began with the Ionian philosophers with whom Greek philosophy and mathematics also began While the Egyptians and Babylonians had accomplished much of astronomical worth it remained for the unrivalled speculative genius of the Greeks in particular their mathematical genius to lay the foundations of the true science of astronomy In this classic study a noted scholar discusses in lucid detail the specific advances made by the Greeks many of whose ideas anticipated the discoveries of modern astronomyPythagoras born at Samos about 572 BC was probably the first to hold that the earth is spherical in shape while his later followers anticipated Copernicus with the thenstartling hypothesis that the earth was not the center of the universe but a planet like the others Heraclides of Pontus c 388315 BC a pupil of Plato declared that the apparent daily rotation of the heavenly bodies is due not to a rotation of the heavenly sphere about an axis through the center of the earth but to the rotation of the earth itself around its own axis Secondly Heraclides discovered that Venus and Mercury revolve around the sun like satellites Perhaps the greatest astronomer of antiquity was Hipparchus who flourished between 161 and 126 BC He compiled a catalog of fixed stars to the number 850 or more made great improvements in the instruments used for astronomical observations and discovered the precession of the equinoxes among other accomplishments The astronomy of Hipparchus takes its definitive form in the Syntaxis commonly called the Almagest of Ptolemy written about AD 150 which held the field until the time of CopernicusThe extraordinary achievements of these and many more Greek theorists are given full coverage in this erudite account which blends exceptional clarity with a readable style to produce a work that is not only indispensable for astronomers and historians of science but easily accessible to scienceminded lay readers. “Dover Bitch”.

This special edition of Apollo Expeditions to the Moon, an official NASA publication, commemorates the fiftieth anniversary of the July 20, 1969, Moon landing with a thrilling insider\'s view of the space program.  Essays by participants — engineers, astronauts, and administrators — recall the program\'s unprecedented challenges. Written in direct, jargon-free language, this compelling adventure features more than 160 dazzling color photographs and scores of black-and-white illustrations. Insights into management challenges as well as its engineering feats include contributions from Michael Collins, Buzz Aldrin, Alan Shepard, and other astronauts NASA administrator James E. Webb Christopher C. Kraft, head of the Mission Control Center and engineer Wernher von Braun. Their informative, exciting narratives explore the issues that set the United States on the path to the Moon, offer perspectives on the program\'s legacy, and examine the particulars of individual missions. Journalist Robert Sherrod chronicles the selection and training of astronauts. James Lovell, commander of the ill-fated Apollo 13, recounts the damaged ship\'s dramatic return to Earth. Geologist and Apollo 17 astronaut Harrison Schmitt discusses the lunar expeditions\' rich harvest of scientific information. These and other captivating firsthand accounts form an ideal introduction to the historic U.S. space program as well as fascinating reading for all ages. This new expanded edition includes a chronology of the Apollo project, additional photographs, and a new Foreword by historian Paul Dickson that offers a modern retrospective of the Moon landing, discussing its place in the world of space exploration and its impact on American history and culture.   This official NASA history chronicles the behind-the-scenes conflicts and cooperation during the Apollo expeditions. It shows how the space agency\'s scientists, who were primarily interested in the Moon itself, worked out their differences with the engineers, who were charged with the astronauts\' safe landing and return. The close collaboration between the scientists and engineers ensured the success of a program that remains a major achievement for both fields. The first half of the book concerns the preparations for the Moon landings, tracing the development of the Apollo science program from the earliest days. The second half documents the flights that followed Apollo 11, during which twelve astronauts explored the lunar surface and returned with samples for investigation. The author drew upon the Lyndon B. Johnson Space Center\'s collection of more than 31,000 Apollo-related documents and conducted more than 300 interviews with program participants to assemble this definitive survey. A towering figure in intellectual history and one of the fathers of modern astronomy, the great mathematician Johannes Kepler (1571–1630) is best known for his discovery of the three laws of planetary motion, which paved the way for a dynamic explanation of the heavenly phenomena. At a time when the Ptolemaic view still prevailed in official circles, Kepler undertook to prove the truth of the Copernican world view and through exceptional perseverance and force of intellect achieved that goal. His epochal intellectual feats are completely and thoroughly described in this splendid work, considered the definitive biography of Kepler. Drawing on a wealth of primary sources, the author presents a fascinating and erudite picture of Kepler\'s scientific accomplishments, his public life (work with Tycho Brahe, the Danish astronomer mathematical appointments at Graz, Prague, and Linz pioneering work with calculus and optics, and more) and his personal life: childhood and youth, financial situation, his mother\'s trial as a witch, his own lifelong fear of religious persecution, his difficulties in choosing one of eleven possible young women as his second wife, and more, through his last years in Ulm and death in Regensburg.Until his death in 1956, Professor Max Caspar was the world\'s foremost Kepler scholar. He had spent over two-thirds of his life assembling, cataloging, describing, analyzing, and editing Kepler\'s works. To this biography he brought tremendous learning and passionate enthusiasm for his subject, creating an unsurpassed resource on the life and work of one of history\'s greatest scientific minds. Originally published in German and superbly translated into English by C. Doris Hellman, Kepler will fascinate scholars and general readers alike. “A carefully reasoned history of astronomy … clearly the work of a man who loved his subject.” — The Times (London) Literary Supplement.Few histories of astronomy offer the special human dimension of this book. For Professor Pannekoek (University of Amsterdam), the history of astronomy consists of the growth of man’s concept of his world. The study of the cosmos became an essential part of the history of human culture, an adventure of the mind.In this well-balanced account of that adventure, the author is at pains to relate the development of astronomy to the social and cultural background in which it is nurtured. Thus, the effect of changes in political conditions, the influence of geography, and the growth of industry and of communications methods are clearly and incisively described.Dr. Pannekoek begins with an unusually detailed account of astronomy in ancient times, including Babylonian sky-lore, Assyrian astrology, the Ptolemaic worldview, Hellenistic astronomy, the epicycle theory, and Arabian astronomy. The growth of astronomy after Copernicus constitutes the second part of the book, acquainting the reader with the epoch-making work of Kepler and Newton and the astonishing developments of celestial mechanics during the eighteenth century. Part III begins with Herschel, the gifted amateur whose observations opened up new horizons, and ends with Eddington’s pioneering studies of the internal constitutions of stars.Comprehensive, well-written and full of small, revealing details that attest to the scope and depth of the author’s learning, this splendid survey belongs in the library of every astronomer — or anyone interested in the grand mystery of the cosmos and man’s attempts to penetrate it. A masterpiece of historical insight and scientific accuracy, this is the definitive work on Greek astronomy and the Copernican Revolution. Beginning with the ancient Egyptians, it ranges from the Pythagoreans and Plato to medieval European and Islamic cosmologies, concluding with detailed surveys of the works of Copernicus, Brahe, and Kepler. Written by a trio of experts, this is the definitive reference on the Apollo spacecraft and lunar modules. It traces the design of the vehicles, their development, and their operation in space. More than 100 photographs and illustrations highlight the text, which begins with NASA\'s origins and concludes with the triumphant Apollo 11 moon mission.
