This is the first complete English translation of Geminos's Introduction to the Phenomena --one of the most important and interesting astronomical works of its type to have survived from Greek antiquity. Gracefully and charmingly written, Geminos's first-century BC textbook for beginning students of astronomy can now be read straight through with understanding and enjoyment by a wider audience than ever before. James Evans and Lennart Berggren's accurate and readable translation is accompanied by a thorough introduction and commentary that set Geminos's work in its historical, scientific, and philosophical context. This book is generously illustrated with diagrams from medieval manuscripts of Geminos's text, as well as drawings and photographs of ancient astronomical instruments. It will be of great interest to students of the history of science, to classicists, and to professional and amateur astronomers who seek to learn more about the origins of their science. Geminos provides a clear view of Greek astronomy in the period between Hipparchos and Ptolemy, treating such subjects as the zodiac, the constellations, the theory of the celestial sphere, lunar cycles, and eclipses. Most significantly, Geminos gives us the earliest detailed discussion of Babylonian astronomy by a Greek writer, thus offering valuable insight into the cross-cultural transmission of astronomical knowledge in antiquity.
"Cosmologists have reasons to believe that the vast universe in which we live is just one of an endless number of other universes within a multiverse--a mind-boggling array that may extend indefinitely in space and endlessly in both the past and the future. In this comprehensive history of multiverse theory, Victor Stenger reviews the key developments in the history of science that led to the current consensus view of astrophysicists, taking pains to explain essential concepts and discoveries in accessible language. He shows that science's emerging understanding of the multiverse--consisting of trillions upon trillions of galaxies--is fully explicable in naturalistic terms with no need for supernatural forces to explain its origin or ongoing existence. How can conceptions of God, traditional or otherwise, be squared with this new worldview? The author shows how, in the light of science, long-held beliefs will need to undergo major revision or otherwise face eventual extinction."--Publisher description.
Translations, mostly by the editor, of writings of Thales, Plato, Aristotle, Ptolemy, Plutarch and others.
"A large number of the passages were included in my sketch of the early history of Greek astronomy which forms the bulk of Aristarchus of Samos, the ancient Copernicus, published in 1913."--Prefatory note.
How many of us today can accurately identify the stars and constellations, the phases of the moon, or the hour and position of the sunrise? Few modern city-dwellers can, but for our forebears such knowledge was crucial. People and the Sky explores the history of mankinds intimate relationship with the sky, and how the lives of our ancestors were cosmically grounded. This erudite and engaging book will be a fundamental resource for students and scholars as well as being gripping reading for a general audience.
Between 1650 and 1750, four Catholic churches were the best solar observatories in the world. Built to fix an unquestionable date for Easter, they also housed instruments that threw light on the disputed geometry of the solar system, and so, within sight of the altar, subverted Church doctrine about the order of the universe. A tale of politically canny astronomers and cardinals with a taste for mathematics, The Sun in the Church tells how these observatories came to be, how they worked, and what they accomplished. It describes Galileo's political overreaching, his subsequent trial for heresy, and his slow and steady rehabilitation in the eyes of the Catholic Church. And it offers an enlightening perspective on astronomy, Church history, and religious architecture, as well as an analysis of measurements testing the limits of attainable accuracy, undertaken with rudimentary means and extraordinary zeal.
The man and the idea that created modern science, as seen by one of today's most celebrated writers. In 1543, the Polish astronomer Nicolaus Copernicus lay on his deathbed, his just-published masterpiece On the Revolutions of the Heavenly Spheres in his hands. At that time, religious doctrine and common sense dictated that the earth ruled the universe, with the sun, moon, planets, and stars all rotating around it. By putting the sun at the center of that cosmology, his book fomented another kind of revolution-a scientific one-that would lead to a completely new view of the universe, and humanity's place in it. As contemporary cosmologists explore the universe's vastness and the nearly insignificant role we play in it, the repercussions from Copernicus's radical step continue to resound.
NASA ScienceCast: The First Martian Marathon
On Earth, a fast runner takes a few hours to complete a marathon. On Mars, it's taken 11 years. NASA's Opportunity rover crossed that finish line in 2015.

Epact is an electronic catalogue of medieval and renaissance scientific instruments from four European museums: the Museum of the History of Science, Oxford, the Istituto e Museo di Storia della Scienza, Florence, the British Museum, London, and the Museum Boerhaave, Leiden. Epact consists of 520 catalogue entries and a variety of supporting material. All European instruments from the four museums by makers who were active before 1600 have been entered in the catalogue.
The Galileo Project is a source of information on the life and work of Galileo Galilei (1564-1642). This project is currently supported by the Office of the Vice President of Computing of Rice University. The initial stages of the project were made possible by a grant from the Council on Library Resources to Fondren Library.
Part of the an online exhibit called "World Treasures of the Library of Congress: Beginnings". This exhibit provides pictures, links, and information about the different cultural views of the universe.
The Starry Messenger is Phase I of the Electronic History of Astronomy developed in the Whipple Museum of the History of Science and the Department of History and Philosophy of Science. The aim of this project is to make available electronically some aspects of the early history of astronomy for the use of students studying the History and Philosophy of Science in the University of Cambridge.
