Davidson thoroughly explores Sagan's science, wrestles with his politics, and plumbs his personal passions with a telling instinct for the revealing underside of a life lived so publicly." -Los Angeles TimesCarl Sagan was one of the most celebrated scientists of this century-the handsome and alluring visionary who inspired a generation to look to the heavens and beyond. His life was both an intellectual feast and an emotional rollercoaster. Based on interviews with Sagan's family and friends, including his widow, Ann Druyan; his first wife, acclaimed scientist Lynn Margulis; and his three sons, as well as exclusive access to many personal papers, this highly acclaimed life story offers remarkable insight into one of the most influential, provocative, and beloved figures of our time-a complex, contradictory prophet of the Space Age.

    Yet 9 out of 10 schools don't even offer computer science classes to students, according to code.org. Help correct this disparity by introducing your kids to the world of computer programming early, with a fun and approachable method. This book begins by introducing the essential concepts of programming with simple instructions, and without specialized computer lingo. Fun projects throughout let kids start putting their computer skills into practice and build their own code using Scratch programming and Python, the two most popular languages.

    In ancient monuments as far apart as Egypt’s Great Sphinx, the strange Andean ruins of Tihuanaco, and Mexico’s awe-inspiring Temples of the Sun and Moon, he reveals not only the clear fingerprints of an as-yet-unidentified civilization of remote antiquity, but also startling evidence of its vast sophistication, technological advancement, and evolved scientific knowledge. A record-breaking number one bestseller in Britain, Fingerprints of the Gods contains the makings of an intellectual revolution, a dramatic and irreversible change in the way that we understand our past—and so our future.And Fingerprints of the Gods tells us something more. As we recover the truth about prehistory, and discover the real meaning of ancient myths and monuments, it becomes apparent that a warning has been handed down to us, a warning of terrible cataclysm that afflicts the Earth in great cycles at irregular intervals of time—a cataclysm that may be about to recur.

     For four hundred years, since early scientists discovered that the universe did not revolve around the earth, people have felt cut off-adrift in a meaningless cosmos. That is about to change. In their groundbreaking new book, The View from the Center of the Universe, Joel R. Primack, Ph.D., one of the world's leading cosmologists, and Nancy Ellen Abrams, a philosopher and writer, use recent advances in astronomy,physics, and cosmology to frame a compelling new theory of how to understand the universe and our role in it. While most of us think of the universe as empty space peppered with stars separated by vast distances, the truth, the authors argue, is far richer and more meaningful. For the first time in history, we know that the universe is more coherent and spiritually significant than anyone ever imagined and that our place in it is actually central to the expanding universe in important ways. According to Primack and Abrams, this new cosmology clarifies how the universe operates, what it's made of, how it may have originated, and how it is evolving. Even more surprising, these startling ideas spring from both cutting-edge science and the metaphors of ancient symbols. The result is a very human book that satisfies our fundamental need for order and meaning in our world and in our lives.

    Things can exist in two places at once and travel backwards and forwards in time. Waves and particles are one and the same, and objects change their behaviour according to whether they are being watched. This is not some alternative universe but the realm of the very small, where quantum mechanics rules. In this weird world of atoms and their constituents, our common sense understanding of reality breaks down - yet quantum mechanics has never failed an experimental test. What does it all mean? For all its weirdness, quantum mechanics has given us many practical technologies including lasers and the transistors that underlie computers and all digital technology. In the future, it promises computers more powerful than any built before, the ability to communicate with absolute privacy, and even quantum teleportation. The Quantum World explores the past, present and future of quantum science, its applications and mind-bending implications. Discover how ideas from quantum mechanics are percolating out into the vast scale of the cosmos - perhaps, in the future, to reveal a new understanding of the big bang and the nature of space and time.ABOUT THE SERIESNew Scientist Instant Expert books are definitive and accessible entry points to the most important subjects in science; subjects that challenge, attract debate, invite controversy and engage the most enquiring minds.

    “In an account chock full of real-world examples reinforced by experimental research, Hood’s marvelous book is an important contribution to the psychological literature that is revealing the actuality of our very irrational human nature.” — ScienceIn the vein of Malcolm Gladwell’s Blink, Mary Roach’s Spook, and Dan Ariely’s Predictably Irrational, The Science of Superstition uses hard science to explain pervasive irrational beliefs and behaviors: from the superstitious rituals of sports stars, to the depreciated value of houses where murders were committed, to the adoration of Elvis.
