Tests the views and metaphor of 19th-century utilitarian philosopher Henry Sidgwick against a variety of contemporary views on ethics, determining that they are defensible and thus providing a defense of objectivism in ethics and of hedonistic utilitarianism.

Using space photographs and scaled maps, demonstrates the actual size of objects in the cosmos, from Buzz Aldrin's historic footprint on the Moon to the entire visible universe, with a gatefold of the Gott-Juric Map of the Universe.

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.

From Nobel prize-winner Roger Penrose, this groundbreaking book is for anyone "who is interested in the world, how it works, and how it got here" (New York Journal of Books). Penrose presents a new perspective on three of cosmology’s essential questions: What came before the Big Bang? What is the source of order in our universe? And what cosmic future awaits us? He shows how the expected fate of our ever-accelerating and expanding universe—heat death or ultimate entropy—can actually be reinterpreted as the conditions that will begin a new “Big Bang.” He details the basic principles beneath our universe, explaining various standard and non-standard cosmological models, the fundamental role of the cosmic microwave background, the paramount significance of black holes, and other basic building blocks of contemporary physics. Intellectually thrilling and widely accessible, Cycles of Time is a welcome new contribution to our understanding of the universe from one of our greatest mathematicians and thinkers.

This lavishly illustrated photographic exploration of the universe will delight everyone intrigued by the night sky. This is the finest collection of color photographs of star clusters, galaxies, and nebulae ever published. Working with the world's most sophisticated telescopes and his own revolutionary techniques, world renowned astronomical photographer David Malin captures distant worlds and phenomena in their astonishing natural colors. These unique pictures are accompanied by nontechnical captions and a lucid text accessible and inspiring to the general reader as well as to astronomers and photographers. The foremost astronomical photographer in the world, David Malin is the discoverer of an enigmatic galaxy now known as Malin-1 and the coauthor of Colours of the Stars and Catalogue of the Universe, both published by Cambridge University Press. His photographs have appeared in locations as diverse as Australian postage stamps and the cover of Life magazine.

NEW YORK TIMES BESTSELLER • Deepak Chopra joins forces with leading physicist Menas Kafatos to explore some of the most important and baffling questions about our place in the world. "A riveting and absolutely fascinating adventure that will blow your mind wide open!" —Dr. Rudolph E. Tanzi What happens when modern science reaches a crucial turning point that challenges everything we know about reality? In this brilliant, timely, and practical work, Chopra and Kafatos tell us that we've reached just such a point. In the coming era, the universe will be completely redefined as a "human universe" radically unlike the cold, empty void where human life is barely a speck in the cosmos. You Are the Universe literally means what it says--each of us is a co-creator of reality extending to the vastest reaches of time and space. This seemingly impossible proposition follows from the current state of science, where outside the public eye, some key mysteries cannot be solved, even though they are the very issues that define reality itself: • What Came Before the Big Bang? • Why Does the Universe Fit Together So Perfectly? • Where Did Time Come From? • What Is the Universe Made Of? • Is the Quantum World Linked to Everyday Life? • Do We Live in a Conscious Universe? • How Did Life First Begin? “The shift into a new paradigm is happening,” the authors write. “The answers offered in this book are not our invention or eccentric flights of fancy. All of us live in a participatory universe. Once you decide that you want to participate fully with mind, body, and soul, the paradigm shift becomes personal. The reality you inhabit will be yours either to embrace or to change.” What these two great minds offer is a bold, new understanding of who we are and how we can transform the world for the better while reaching our greatest potential.

The authors tell the epic story of the universe from an inspired new perspective, weaving the findings of modern science together with enduring wisdom found in the humanistic traditions of the West, China, India, and indigenous peoples. This book is part of a larger project that includes a documentary film, educational DVD series, and Web site.
