A sweeping tour of the galaxies, from our Milky Way to infinity. Galaxies are glittering islands in the Universe, interwoven in the web of Dark Matter. From Earth’s mountaintops enormous telescopes peer deep beyond the Milky Way, while space telescopes locate majestic images, and through seemingly miraculous technology, capture them for us to look at and learn with amazement. Featuring the most recent, best, and even startling images with detailed captions highlighting accessible text, Galaxies shows the restless universe beyond our atmosphere. Photographs are from more than 30 of the world’s largest ground-based telescopes, including the largest to date, the European Southern Observatory’s Very Large Telescope in Chile. It will not be until 2025 that an even larger telescope, the Giant Magellan Telescope, will join its neighbour in the mountains of Chile and open a wider window into the dark Universe. Images are also featured from the Hubble Space Telescope, which has continued to operate long past its expected life and has continued to astound and astonish stargazers worldwide.

Galileo's 1632 book, "Dialogue on the Two Chief World Systems, Ptolemaic and Copernican," comes alive for twentieth-century readers thanks to Maurice Finocchiaro's brilliant new translation and presentation. Condemned by the Inquisition for its heretical proposition that the earth revolves around the sun, Galileo's masterpiece takes the form of a debate, divided into four "days," among three highly articulate gentlemen.
Finocchiaro sets the stage with his introduction, which not only provides the human and historical framework for the "Dialogue" but also admits the reader gracefully into the basic non-Copernican understanding of the universe that would have been shared by Galileo's original audience. The translation of the "Dialogue" is abridged in order to highlight its essential content, and Finocchiaro gives titles to the various parts of the debate as a guide to the principal topics. By explicating his own critical reading of this text that is itself an exercise in critical reasoning on a gripping real-life controversy, he illuminates those universal, perennial activities of the human mind that make Galileo's book a living document. This is a concrete, hands-on introduction to critical thinking. The translation has been made from the Italian text provided in volume 7 of the Critical National Edition of Galileo's complete works edited by Antonio Favaro. The translator has also consulted the 1632 edition, as well as the other previous English translations, including California's 1967 version.
"Galileo on the World Systems" is a remarkably nuanced interpretation of a classic work and will give readers the tools to understand and evaluate for themselves one of the most influential scientific books in Western civilization.

In 1543, Nicolaus Copernicus publicly defended his hypothesis that the earth is a planet and the sun a body resting near the center of a finite universe. But why did Copernicus make this bold proposal? And why did it matter? The Copernican Question reframes this pivotal moment in the history of science, centering the story on a conflict over the credibility of astrology that erupted in Italy just as Copernicus arrived in 1496. Copernicus engendered enormous resistance when he sought to protect astrology by reconstituting its astronomical foundations. Robert S. Westman shows that efforts to answer the astrological skeptics became a crucial unifying theme of the early modern scientific movement. His interpretation of this "long sixteenth century," from the 1490s to the 1610s, offers a new framework for understanding the great transformations in natural philosophy in the century that followed.

Since humans first looked up at the stars, astronomy has had a particular ability to stir the imagination and challenge the thinking of scientists and non-scientists alike. Astronomy: The Human Quest for Understanding is an introductory astronomy textbook specifically designed to relate to non-science majors across a wide variety of disciplines, nurture their curiosity, and develop vital science-based critical-thinking skills. This textbook provides an introduction to how science operates in practice and what makes it so successful in uncovering nature's secrets. Given that the study of astronomy dates back thousands of years, it is the ideal subject for tracing the development of the physical sciences and how our evolving understanding of nature has influenced, and been influenced by, mathematics, philosophy, religion, geography, politics, and more. This historical approach also illustrates how wrong turns have been taken, and how the inherent self-correcting nature of science through constant verification and the falsifiability of truly scientific theories ultimately leads us back to a more productive path in our quest for understanding. This approach also points out why, as a broadly educated citizenry, students of all disciplines must understand how scientists arrive at conclusions, and how science and technology have become central features of modern society. In discussing this fascinating and beautiful universe of which we are a part, it is necessary to illustrate the fundamental role that mathematics plays in decoding nature's mysteries. Unlike other similar textbooks, some basic mathematics is integrated naturally into the text, together with interpretive language, and supplemented with numerous examples; additional tutorials are provided on the book's companion website. Astronomy: The Human Quest for Understanding leads the reader down the path to our present-day understanding of our Solar System, stars, galaxies, and the beginning and evolution of our universe, along with profound questions still to be answered in this ancient, yet rapidly changing field.

A treasure for anyone interested in early modern India and the history of mathematics, this first English translation of the Siddhantasundara reveals the fascinating work of the scholar-astronomer Jnanaraja (circa 1500 C.E.). Toke Lindegaard Knudsen begins with an introduction to the traditions of ancient Hindu astronomy and describes what is known of Jnanaraja's life and family. He translates the Sanskrit verses into English and offers expert commentary on the style and substance of Jnanaraja's treatise.

The Siddhantasundara contains a comprehensive exposition of the system of Indian astronomy, including how to compute planetary positions and eclipses. It also explores deep, probing questions about the workings of the universe and sacred Hindu traditions. In a philosophical discussion, the treatise seeks a synthesis between the cosmological model used by the Indian astronomical tradition and the cosmology of a class of texts sacred in Hinduism. In his discourse, which includes a discussion of the direction of down and adhesive antipodeans, Jnanaraja rejects certain principles from the astronomical tradition and reinterprets principles from the sacred texts. He also constructs a complex poem on the seasons, many verses of which have two layers of meaning, one describing a season, the other a god's activities in that season.

The Siddhantasundara is the last major treatise of Indian astronomy and cosmology to receive serious scholarly attention, Knudsen's careful effort unveils the 500-year-old Sanskrit verses and shows the clever quirkiness of Jnanaraja's writing style, his keen use of mathematics, and his subtle philosophical arguments.

In Ten Short Lessons in Time Travel, Brian Clegg takes us on a fascinating and up-to-date tour of the workings of the universe that suggest the possibility of journeying back and forth through time.

Einstein's special theory of relativity told us that time travel to the future was possible, and later his general theory of relativity showed us that loops in spacetime could exist, meaning that we might be able to bend time backwards, too. But what are the practicalities of making time travel possible? What do we still need to know? How do we deal with paradoxical twists in time - and could quantum physics hold the answer? From the imagination of novelists to current research, 10 Short Lessons in Time Travel is a grand tour of the essential lessons in this game-changing area of physics.

About the series: The Pocket Einstein series is a collection of essential pocket-sized guides for anyone looking to understand a little more about some of the most important and fascinating areas of science in the twenty-first century. Broken down into ten simple lessons and written by leading experts in their field, discover the ten most important takeaways from those areas of science you've always wanted to know more about.

Volume IV of the Collected Works of V.I. Arnold includes papers written mostly during the period from 1980 to 1985. Arnold's work of this period is so multifaceted that it is almost impossible to give a single unifying theme for it. It ranges from properties of integral convex polygons to the large-scale structure of the Universe. Also during this period Arnold wrote eight papers related to magnetic dynamo problems, which were included in Volume II, mostly devoted to hydrodynamics. Thus the topic of singularities in symplectic and contact geometry was chosen only as a "marker" for this volume.There are many articles specifically translated for this volume. They include problems for the Moscow State University alumni conference, papers on magnetic analogues of Newton's and Ivory's theorems, on attraction of dust-like particles, on singularities in variational calculus, on Poisson structures, and others. The volume also contains translations of Arnold's comments to Selected works of H. Weyl and those of A.N. Kolmogorov. Vladimir Arnold was one of the great mathematical scientists of our time. He is famous for both the breadth and the depth of his work. At the same time he is one of the most prolific and outstanding mathematical authors.

"Discoverers of the Universe" tells the gripping story of William Herschel, the brilliant, fiercely ambitious, emotionally complex musician and composer who became court astronomer to Britain's King George III, and of William's sister, Caroline, who assisted him in his observations of the night sky and became an accomplished astronomer in her own right. Together, they transformed our view of the universe from the unchanging, mechanical creation of Newton's clockmaker god to the ever-evolving, incredibly dynamic cosmos that it truly is.

William was in his forties when his amateur observations using a homemade telescope led to his discovery of Uranus, and an invitation to King George's court. He coined the term "asteroid," discovered infrared radiation, was the first to realize that our solar system is moving through space, discovered 2,500 nebulae that form the basis of the catalog astronomers use today, and was unrivalled as a telescope builder. Caroline shared William's passion for astronomy, recording his observations during night watches and organizing his papers for publication. She was the first salaried woman astronomer in history, a pioneer who herself discovered nine comets and became a role model for women in the sciences.

Written by the world's premier expert on the Herschels, "Discoverers of the Universe" traces William and Caroline's many extraordinary contributions to astronomy, shedding new light on their productive but complicated relationship, and setting their scientific achievements in the context of their personal struggles, larger-than-life ambitions, bitter disappointments, and astonishing triumphs.

How can shadows determine the date and time of a painting by Johannes Vermeer? How did the Moon and tides cause the loss of King John's crown jewels? In his newest book, Professor Olson, author of Celestial Sleuth and Further Adventures of the Celestial Sleuth, explores how astronomical clues can uncover fascinating new details about art, history, and literature. He begins with an accessible introduction to amateur "celestial sleuthing," showing how to use your astronomical knowledge, software, archives, vintage maps, historical letters and diaries, military records, and other resources to investigate the past. Follow along as Professor Olson then explores twenty real-world cases where astronomy has helped answer unresolved questions or correct longstanding interpretations about an event. Examples involve artists such as Vermeer, Monet, and O'Keeffe; the historical exploits of Alexander the Great, the desert travels of the Death Valley '49ers, and a meeting between Franklin D. Roosevelt and Winston Churchill in Marrakech; and literary works by Chaucer, Shakespeare, and Longfellow. Packed with dozens of full-color illustrations, this book will enrich your knowledge of the past and equip you with all the tools you'll need to become a celestial sleuth yourself. "Many people have a passion for art, or world history, or great literature, or even astronomy - but seldom in all these things at once. This remarkable book by Donald Olson of Texas State University will put you in touch with such seemingly unrelated endeavors. It will open your eyes and broaden your mind as little else could." Roger W. Sinnott, Sky & Telescope

An engaging critique of the science and metaphysics behind our understanding of the universe   The James Webb Space Telescope, when launched in 2021, will be the premier orbital observatory, capable of studying every phase of the history of the universe, from the afterglow of the Big Bang to the formation of our solar system. Examining the theoretical basis for key experiments that have made this latest venture in astrophysics possible, Bjørn Ekeberg reveals that scientific cosmology actually operates in a twilight zone between the physical and metaphysical.  Metaphysical Experiments explains how our current framework for understanding the universe, the Big Bang theory, is more determined by a deep faith in mathematical universality than empirical observation. Ekeberg draws on philosophical insights by Spinoza, Bergson, Heidegger, and Arendt; on the critical perspectives of Latour, Stengers, and Serres; and on cutting-edge physics research at the Large Hadron Collider, to show how the universe of modern physics was invented to reconcile a Christian metaphysical premise with a claim to the theoretical unification of nature. By focusing on the nonmathematical assumptions underlying some of the most significant events in modern science, Metaphysical Experiments offers a critical history of contemporary physics that demystifies such concepts as the universe, particles, singularity, gravity, blackbody radiation, the speed of light, wave/particle duality, natural constants, black holes, dark matter, and dark energy. Ekeberg’s incisive reading of the metaphysical underpinnings of scientific cosmology offers an innovative account of how we understand our place in the universe.

We live on a dynamic Earth shaped by both natural processes and the impacts of humans on their environment. It is in our collective interest to observe and understand our planet, and to predict future behavior to the extent possible, in order to effectively manage resources, successfully respond to threats from natural and human-induced environmental change, and capitalize on the opportunities ? social, economic, security, and more ? that such knowledge can bring. By continuously monitoring and exploring Earth, developing a deep understanding of its evolving behavior, and characterizing the processes that shape and reshape the environment in which we live, we not only advance knowledge and basic discovery about our planet, but we further develop the foundation upon which benefits to society are built. Thriving on Our Changing Planet presents prioritized science, applications, and observations, along with related strategic and programmatic guidance, to support the U.S. civil space Earth observation program over the coming decade.

This brief approaches General Relativity from a planetary navigation perspective, delving into the unconventional mathematical methods required to produce computer software for space missions. It provides a derivation of the Einstein field equations and describes experiments performed on the Near Earth Asteroid Rendezvous mission, spanning General Relativity Theory from the fundamental assumptions to experimental verification. The software used for planetary missions is derived from mathematics that use matrix notation. An alternative is to use Einstein summation notation, which enables the mathematics to be presented in a compact form but makes the geometry difficult to understand. In this book, the relationship of matrix notation to summation notation is shown. The purpose is to enable the reader to derive the mathematics used in the software in either matrix notation or summation notation. This brief is a useful tool for advanced students and young professionals embarking on careers in planetary navigation.
