In an alternate world where Ptolemaic astronomy is real, scientists from the thousand year empire of Alexander the Great attempt a journey to the sun.

A thousand years after Alexander the Great, the Greek Empire has expanded over the world with the help of advanced technology. Its plans for Total Domination of the entire planet will be complete once the war with the empire of the middle kingdom has been won. The scientist Aias, commander of the celestial ship Chandra's Tear, prepares to embark on a secret mission to the sun, to steal a piece of the purest elemental fire. This ultimate piece of celestial matter will form the basis for a weapon capable of decisively ending the war with the Taoists of the Far East.

Celestial Bodies is the International Booker-winning and internationally bestselling novel from Jokha Alharthi. Set in the village of al-Awafi in Oman, we encounter three sisters: Mayya, who marries Abdallah after a heartbreak; Asma, who marries from a sense of duty; and Khawla who rejects all offers while waiting for her beloved, who has emigrated to Canada. These three women and their families witness Oman evolve from a traditional, slave-owning society slowly redefining itself after the colonial era, to the crossroads of its complex present. Elegantly structured and taut, Celestial Bodies is a coiled spring of a novel, telling of Oman’s coming-of-age through the prism of one family’s losses and loves. PRAISE FOR CELESTIAL BODIES "An innovative reimagining of the family saga . . . Celestial Bodies is itself a treasure house: an intricately calibrated chaos of familial orbits and conjunctions, of the gravitational pull of secrets” NEW YORK TIMES BOOK REVIEW "The great pleasure of reading Celestial Bodies is witnessing a novel argue, through the achieved perfection of its form, for a kind of inquiry that only the novel can really conduct. The ability to move freely through time, the privileged access to the wounded privacies of many characters, the striking diversity of human beings across a relatively narrow canvas, the shock waves as one generation heaves, like tectonic plates, against another, the secrets and lapses and repressions, at once intimate and historical, the power, indeed, of an investigation that is always political and always intimate―here is the novel being supremely itself, proving itself up to the job by changing not its terms of employment but the shape of the task." THE NEW YORKER "Breathtaking. The tale is replete with history, poetry, and philosophy, but also slavery, broken marriages, passion, and not-so-secret lovers." THE ATLAN

Celestial Encounters traces the history of attempts to solve the problem of celestial mechanics first posited in Isaac Newton's Principia in 1686. More generally, the authors reflect on mathematical creativity and the roles that chance encounters, politics, and circumstance play in it. 23 halftones. 64 line illustrations.

If scientists can’t touch the Sun, how do they know what it’s made of? And if we can’t see black holes, how can we be confident they exist? Gravitational physicist David Garfinkle and his brother, science fiction writer Richard Garfinkle, tackle these questions and more in Three Steps to the Universe, a tour through some of the most complex phenomena in the cosmos and an accessible exploration of how scientists acquire knowledge about the universe through observation, indirect detection, and theory. The authors begin by inviting readers to step away from the Earth and reconsider our Sun. What we can directly observe of this star is limited to its surface, but with the advent of telescopes and spectroscopy, scientists know more than ever about its physical characteristics, origins, and projected lifetime. From the Sun, the authors journey further out into space to explore black holes. The Garfinkle brothers explain that our understanding of these astronomical oddities began in theory, and growing mathematical and physical evidence has unexpectedly supported it. From black holes, the authors lead us further into the unknown, to the dark matter and energy that pervade our universe, where science teeters on the edge of theory and discovery. Returning from the depths of space, the final section of the book brings the reader back down to Earth for a final look at the practice of science, ending with a practical guide to discerning real science from pseudoscience among the cacophony of print and online scientific sources. Three Steps to the Universe will reward anyone interested in learning more about the universe around us and shows how scientists uncover its mysteries.

A step-by-step guide to predicting and calculating the positions of stars, planets, the sun, the moon, and satellites using a personal computer and high school mathematics—for amateur astronomers 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 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.

"Celestial Inclinations: A Life of Augustus provides a new perspective on the life and career of the first Roman emperor Augustus (63 B.C.-A.D. 14) and presents the case that Augustus used his knowledge of the celestial sphere in various ways to confirm for himself and convey to others that the heavens supported his activities on earth and his inevitable greatness. The book is based on fresh assessments of relevant ancient historical, literary, astronomical, astrological, and artistic sources for the years prior to and during the life of Augustus. The book combines these sources with astronomical sky maps and astrological diagrams to offer fresh interpretations of critical events in the life of Augustus at a time when the celestial sphere had come to play an important cultural and political role. Topics include the identification of the celestial object that appeared at the ludi in honor of Caesar in 44 B.C.; the Battle of Actium; the iconography of the Tellus Relief Panel on the Ara Pacis Augustae; the Ludi Saeculares; Augustus' major building projects in Rome; and Augustus' interactions with major figures of the period such as Cicero, Caesar, Agrippa, and Antonius"--

A theoretical astrophysicist explores the ideas that transformed our knowledge of the universe over the past century. The cosmos, once understood as a stagnant place, filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is someone at the forefront of the research—an astrophysicist who literally creates maps of invisible matter in the universe. She not only explains for a wide audience the science behind these essential ideas but also provides an understanding of how radical scientific theories gain acceptance. The formation and growth of black holes, dark matter halos, the accelerating expansion of the universe, the echo of the big bang, the discovery of exoplanets, and the possibility of other universes—these are some of the puzzling cosmological topics of the early twenty-first century. Natarajan discusses why the acceptance of new ideas about the universe and our place in it has never been linear and always contested even within the scientific community. And she affirms that, shifting and incomplete as science always must be, it offers the best path we have toward making sense of our wondrous, mysterious universe. “Part history, part science, all illuminating. If you want to understand the greatest ideas that shaped our current cosmic cartography, read this book.”—Adam G. Riess, Nobel Laureate in Physics, 2011 “A highly readable, insider’s view of recent discoveries in astronomy with unusual attention to the instruments used and the human drama of the scientists.”—Alan Lightman, author of The Accidental Universe and Einstein's Dream

"Startlingly talented . . . he survives the inevitable, apt comparisons to Kurt Vonnegut and writes in a tenderly mordant voice all his own." -Janet Maslin, The New York Times In this novel rich in character, Junior Thibodeau grows up in rural Maine in a time of Atari, baseball cards, pop Catholicism, and cocaine. He also knows something no one else knows-neither his exalted parents, nor his baseball-savant brother, nor the love of his life (she doesn't believe him anyway): The world will end when he is thirty-six. While Junior searches for meaning in a doomed world, his loved ones tell an all-American family saga of fathers and sons, blinding romance, lost love, and reconciliation-culminating in one final triumph that reconfigures the universe. A tour de force of storytelling, Everything Matters! is a genre-bending potpourri of alternative history, sci-fi, and the great American tale in the tradition of John Irving and Margaret Atwood.
