New fundamental forces of Nature? New forms of "dark” energy? Signals from epochs preceding the Big Bang? Is our space-time unique? Only a joint study of the three topics examined in this book—gravity, strings and particles—may provide answers to these questions. Such a study may also provide the key to solving one of the most fascinating mysteries of modern science, namely: Besides time and the three spatial dimensions, how many other dimensions...

Welcome to the Universe is a personal guided tour of the cosmos by three of today's leading astrophysicists. Inspired by the enormously popular introductory astronomy course that Neil deGrasse Tyson, Michael A. Strauss, and J. Richard Gott taught together at Princeton, this book covers it all--from planets, stars, and galaxies to black holes, wormholes, and time travel. Describing the latest discoveries in astrophysics, the informative and entertaining...

"Detective thriller meets astrophysics in this adventure into neutrinos and the scientists who pursue them For more than eighty years, brilliant and eccentric scientists around the world have been searching for the incredibly small bits of matter we call neutrinos. Trillions of these ghostly particles pass through our bodies every second, but they are so pathologically shy that neutrino hunters have to use Olympic-size pools deep underground and...

"Roger Penrose, Co-Winner of the Nobel Prize in Physics, Royal Swedish Academy of Sciences" Stephen Hawking (1942–2018) was the Lucasian Professor of Mathematics Emeritus at the University of Cambridge. Roger Penrose is a Nobel Prize–winning physicist and the author of Cycles of Time and The Road to Reality (both Vintage). He is the Rouse Ball Professor of Mathematics Emeritus at the University of Oxford. From two of the world's great physicists-Stephen...

The Universe May Be a Mystery,But It's No SecretMichael Schneider leads us on a spectacular, lavishly illustrated journey along the numbers one through ten to explore the mathematical principles made visible in flowers, shells, crystals, plants, and the human body, expressed in the symbolic language of folk sayings and fairy tales, myth and religion, art and architecture. This is a new view of mathematics, not the one we learned at school but a comprehensive...

An introduction to some of the lesser well-known but far more interesting stars in our galaxy.

Using Space to Save Earth Veteran science journalist William E Burrows offers a bold new mission for the U.S. space program: to protect the Earth from the ever-growing number of perils that threaten our way of life – and even our very survival. We are living through one of the most dangerous times in human history. Nuclear, chemical, and biological weapons technology are proliferating, and missile technology is falling into more and more hands....

The first section the book, "Deconstructing Physics" surveys modern concepts in physics and astronomy. This section helps make quarks, baryons, and bosons understandable, and in doing so makes modern science accessible to non-physicists. The second section of the book, "The Nature of Space" introduces a group of cosmological concepts. The author uses a series of analogies to help explain interesting, but often opaque, subjects, such as dark matter,...
