Book Description
Ptolemy's Almagest is one of the most influential scientific works in history. A masterpiece of technical exposition, it was the basic textbook of astronomy for more than a thousand years, and still is the main source for our knowledge of ancient astronomy. This translation, based on the standard Greek text of Heiberg, makes the work accessible to English readers in an intelligible and reliable form. It contains numerous corrections derived from medieval Arabic translations and extensive footnotes that take account of the great progress in understanding the work made in this century, due to the discovery of Babylonian records and other researches. It is designed to stand by itself as an interpretation of the original, but it will also be useful as an aid to reading the Greek text.

Book Description
Most astronomers and physicists now believe that the matter content of the Universe is dominated by dark matter: hypothetical particles which interact with normal matter primarily through the force of gravity. Though invisible to current direct detection methods, dark matter can explain a variety of astronomical observations. This book describes how this theory has developed over the past 75 years, and why it is now a central feature of extragalactic astronomy and cosmology. Current attempts to directly detect dark matter locally are discussed, together with the implications for particle physics. The author comments on the sociology of these developments, demonstrating how and why scientists work and interact. Modified Newtonian Dynamics (MOND), the leading alternative to this theory, is also presented. This fascinating overview will interest cosmologists, astronomers and particle physicists. Mathematics is kept to a minimum, so the book can be understood by non-specialists.

Book Description
The fascinating story of science in pursuit of the ghostly, ubiquitous subatomic particle—the neutrino. Isaac Asimov is said to have observed of the neutrino: “The only reason scientists suggested its existence was their need to make calculations come out even. And yet the nothing-particle was not a nothing at all.” In fact, as one of the most enigmatic and most populous particles in the universe—about 100 trillion are flying through you every second—the neutrino may hold the clues to some of our deepest cosmic mysteries. In Ghost Particle, Alan Chodos and James Riordon recount the dramatic history of the neutrino—from the initial suggestion that the particle was merely a desperate solution to a puzzle that threatened to undermine the burgeoning field of particle physics to its modern role in illuminating the universe via neutrino telescopes. Alan Chodos and James Riordon are deft and engaging guides as they conduct readers through the experiences of intrepid scientists and the challenges they faced, and continue to face, in their search for the ghostly neutrino. Along the way, the authors provide expert insight into the significance of neutrino research from the particle’s first, momentous discovery to recent, revolutionary advances in neutrino detection and astronomy. Chodos and Riordon describe how neutrinos may soon provide clues to some of the biggest questions we encounter today, including how to understand the dark matter that makes up most of the universe—and why anything exists in the universe at all.

Book Description
Advances made by physicists in understanding matter, space, and time and by astronomers in understanding the universe as a whole have closely intertwined the question being asked about the universe at its two extremesâ€"the very large and the very small. This report identifies 11 key questions that have a good chance to be answered in the next decade. It urges that a new research strategy be created that brings to bear the techniques of both astronomy and sub-atomic physics in a cross-disciplinary way to address these questions. The report presents seven recommendations to facilitate the necessary research and development coordination. These recommendations identify key priorities for future scientific projects critical for realizing these scientific opportunities.

Book Description
Science has made tremendous advances in overcoming superstition and replacing “revealed truth” with proven factual truth. Quantum mechanics and the Theories of Relativity have contributed immensely to these advances. But, in spite of this, certain absurdities, referred to as the “quantum enigma”, have emerged from the standard interpretation of quantum mechanics. This has been recognized by some physicists, but the absurdities have been largely ignored by most to the detriment of our understanding of the creation, evolution and nature of the universe. Albert Einstein himself felt quantum mechanics was incomplete and spent the last 3 or 4 decades of his life fighting the proponents of the absurdities. It has been claimed that Einstein lost this battle, but the author disagrees and provides proof of the opposite. Einstein may have made slight mistakes in developing his Theories of Relativity, however, that may have unintentionally contributed to the absurdities and the author’s work supports the statement that "Einstein may have been wrong just where most thought he was right and right just where most thought he was wrong." The author provides a new analysis of space and time and corrections to aspects of quantum mechanics and the Theories of Relativity that may eliminate the absurdities. This could provide a new understanding of the birth, evolution and nature of the universe and possible explanations for dark energy and dark matter. This is presented in a manner that can be understood and appreciated by all curious folks, not just physicists, and will help them understand their universe and the amazing things physicists have accomplished.

Book Description
The award-winning former editor of Science News shows that one of the most fascinating and controversial ideas in contemporary cosmology—the existence of multiple parallel universes—has a long and divisive history that continues to this day. We often consider the universe to encompass everything that exists, but some scientists have come to believe that the vast, expanding universe we inhabit may be just one of many. The totality of those parallel universes, still for some the stuff of science fiction, has come to be known as the multiverse. The concept of the multiverse, exotic as it may be, isn’t actually new. In The Number of the Heavens, veteran science journalist Tom Siegfried traces the history of this controversial idea from antiquity to the present. Ancient Greek philosophers first raised the possibility of multiple universes, but Aristotle insisted on one and only one cosmos. Then in 1277 the bishop of Paris declared it heresy to teach that God could not create as many universes as he pleased, unleashing fervent philosophical debate about whether there might exist a “plurality of worlds.” As the Middle Ages gave way to the Renaissance, the philosophical debates became more scientific. René Descartes declared “the number of the heavens” to be indefinitely large, and as notions of the known universe expanded from our solar system to our galaxy, the debate about its multiplicity was repeatedly recast. In the 1980s, new theories about the big bang reignited interest in the multiverse. Today the controversy continues, as cosmologists and physicists explore the possibility of many big bangs, extra dimensions of space, and a set of branching, parallel universes. This engrossing story offers deep lessons about the nature of science and the quest to understand the universe.

Book Description
In this strikingly original book, a world-renowned cosmologist and an innovative writer of the history and philosophy of science uncover an astonishing truth: Humans actually are central to the universe. What does this mean for our culture and our personal lives? The answer is revolutionary: a science-based cosmology that allows us to understand the universe as a whole and our extraordinary place in it.
