A text for a nonmajor introductory course, serving as an introduction to astronomy and to science in general. Treatment moves from the solar system to stars to galaxies, with a final chapter on cosmology. Includes margin notes and definitions, review quizes, discussion questions, calculation exercises, activities, and questions keyed to the publisher's Web site. Optional mathematical exercises are interspersed through the text, with worked examples and answers. Boxed readings discuss topics of interest such as the search for extraterrestrial life, and present personal accounts of astronomers. This second edition includes color photos from the Hubble Space Telescope and incorporates the latest research in the field. There is expanded discussion of the Hubble device, findings from recent missions, and interstellar matter and star formation. This edition has a larger page size, allowing for enlarged color photos and illustrations, and color cues located at the first reference in the text to each figure. Figures are placed on the same page as accompanying material. Annotation copyrighted by Book News, Inc., Portland, OR

No scientific quest is as compelling as the search for the key to understand the universe—the elusive unified “Theory of Everything”—a theory so concise it could fit on a T-shirt. Lively and thought-provoking, Universe on a T-Shirt tells the fascinating story of the search for the Holy Grail of physics. Dan Falk places this intriguing story in its historical context, tracing the quest from ancient Greece to the breakthroughs of Newton, Maxwell, and Einstein, to the excitement over string theory and today’s efforts to merge quantum theory with general relativity. With as much emphasis on history as on science, Falk’s accessible approach is ideal for anyone intrigued by the advances in modern physics but still wondering what theoretical physicists are searching for, and why. Today’s physicists use sophisticated methods, but their goal—the search for simplicity—has not changed since the time of the ancient Greeks. Universe on a T-Shirt is filled with quirky personalities, brilliant minds, and bold ideas—high science and high drama. "An admirably concise and comprehensive overview of cosmology . . . [that] offers intriguing insights into the philosophic and personal outlooks motivating the scientists involved, from the ancient Greeks through Newton and Einstein . . . [and] Stephen Hawking and Ed Witten.”—Booklist

The deepest concern of every thinking individual must surely be with the three great subjects which comprise the title of the book, and with the relationships between them. The profound concepts inevitably involved in a discussion of such a theme are presented with great clarity and wisdom, and the many diagrams and charts with which the ideas are illustrated are invaluable aids to comprehension. East and West meet here in enlightened synthesis. Chapters include such topics as Cosmic Consciousness, The Monad and the Logos, Involution and Evolution, Mathematics as the Basis of Manifestation and Reality and Consciousness. The book also includes both a glossary and index.

In a revolutionary new theory, Dr. Robert Foot of the University of Melbourne argues that meteorites composed of mirror matter could impact with the Earth without leaving any ordinary fragments. Indeed, the theory seems to provide a simple explanation for the puzzling Tunguska event--the blast which destroyed a huge area of Siberian forest in 1908. While scientists have attributed this explosion to an ordinary meteorite, no traces of such an object have ever been found. Moreover, there are frequent smaller such events, occurring on a yearly basis, which are even more puzzling. Foot's new book lays clear the scientific case for mirror matter. It describes the fascinating evidence for its existence including, astronomical observations suggesting that most of our galaxy is made from a new form of matter--dark matter. It explains puzzling Jupiter sized planets only a few million miles from their host star, and the mysterious slowing down of spacecraft in our solar system. Remarkably, it is also possible that Pluto might even be a mirror world, which would explain various anomalous features of its orbit. Perhaps the most important consequence of all this--if true--is the possibility of actually extracting the mirror matter from the Tunguska impact site and other such sites on earth. Invisible asteroids and other cosmic bodies made of a new form of matter may pose a threat to Earth, agrees a noted Australian physicist. But the mirror matter idea has not attracted a huge following among physicists. In a recent UPI article, Howard Georgi of Harvard University says, "Foot's ideas have not attracted a huge following in the community that cares about these things, perhaps because the problems they solve, while interesting, are not the most critical puzzles that we are wrestling with." Nevertheless, mirror matter, if it exists, would be a completely new type of material with a potentially huge commercial value. Its scientific value would be of no less importance. FROM THE BACK COVER Nearly 50 years ago it was discovered that the fundamental particles, such as the electron and proton, have `left-handed' interactions; they do not respect mirror symmetry. This experimental fact motivates the idea that a set of `mirror particles' exist. The left-handedness of the ordinary particles can then be balanced by the right-handedness of the mirror particles. In this way mirror reflection symmetry can exist but requires something profoundly new. It requires the existence of a completely new form of matter called `mirror matter'. Remarkably the mirror matter theory is capable of simply explaining a large number of contemporary puzzles in astrophysics and particle physics. The evidence ranges from observations suggesting that most of the matter in the Universe is invisible, to unexpected properties of ghostly particles called `neutrinos'. This book explains this fascinating theory and its evidence at a level accessible to the non-specialist.

Max Tegmark leads us on an astonishing journey through past, present and future, and through the physics, astronomy and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate multiverse. In a dazzling combination of both popular and groundbreaking science, he not only helps us grasp his often mind-boggling theories, but he also shares with us some of the often surprising triumphs and disappointments that have shaped his life as a scientist. Fascinating from first to last—this is a book that has already prompted the attention and admiration of some of the most prominent scientists and mathematicians.

Designed for the nonscience major, In Quest of the Universe, Sixth Edition, is a comprehensive, student-friendly introduction to astronomy. This accessible text guides readers through the development of historical and current astronomical theories to provide a clear account of how science works. Koupelis' distinct explanations acquaint students with their own solar system before moving on to the stars and distant galaxies. This flexible approach allows instructors to arrange the modules to fit their own course needs. With numerous interactive learning tools, the Starry Night planetary software package, and stunning visuals and up-to-date content, In Quest with the Universe, Sixth Edition is an exciting overview of this ever-changing discipline.
