Their first intimation of our existence might well be a Super Bowl broadcast or a stray transmission from the Playboy channel. But, of course, they might seem equally strange to us. How strange? Their senses could be entirely different from ours—they might see in the infrared or “hear” radio waves.What would aliens look like? An intelligent octopus-like creature is certainly plausible. What about odd numbers of limbs—a three-legged alien with three arms and three eyes? What about an entire planet of immobile, silicon-based “trees” that communicate with each other via electrical signals?The Science of Aliens gets weirder still. Could a giant interstellar cloud be “alive” and intelligent? Could creatures live at extremely high pressures and temperatures? And which of these many possibilities would be similar enough to us that they could communicate with them, or they with us? Would they have any interest in abducting us? Would they want to have sex with us?In classic Pickover style, here is speculation at the far edge of knowledge—and beyond.

    A rapturous guide through five major Ice Age sites” (Archaeology).   The cave art of France’s Dordogne region is world-famous for the mythology and beauty of its remarkable drawings and paintings. These ancient images of lively bison, horses, and mammoths, as well as symbols of all kinds, are fascinating touchstones in the development of human culture, demonstrating how far humankind has come and reminding us of the ties that bind us across the ages.   Over more than twenty-five years of teaching and research, Christine Desdemaines-Hugon has become an unrivaled expert in the cave art and artists of the Dordogne region. In Stepping-Stones she combines her expertise in both art and archaeology to convey an intimate understanding of the “cave experience.” Her keen insights communicate not only the incomparable artistic value of these works but also the near-spiritual impact of viewing them for oneself.   Focusing on five fascinating sites, including the famed Font de Gaume and others that still remain open to the public, this book reveals striking similarities between art forms of the Paleolithic and works of modern artists and gives us a unique pathway toward understanding the culture of the Dordogne Paleolithic peoples and how it still touches our lives today.   “Her vivid descriptions help readers visualize the Cro-Magnon man or woman painting the beautiful bison, horses, mammoths, and other symbols. [A] fine reading experience.” —Library Journal

    Each image alone exposes a nugget of our planet's magnificence; the totality of the collection goes beyond our imagination. Turning the pages, viewers are struck by the richness of life on Earth. One photograph is more awe-inspiring than the next--chosen by veteran National Geographic Magazine photo editors to present what is visually incredible. The photographs are drawn from the popular "Visions of Earth" feature in the magazine, (rated #1 by readers), from our own storied Image Collection, and from renowned photographers throughout the world, many never-before published.Enthralling images fill the book in a gallery of stunning landscapes, fascinating people, amazing animals, and unexpected glimpses of the usual and unusual. Puffins' beaks signal breeding time in Norway and a speckled emperor moth in South Africa diverts predators with an illusion. An elephant takes a morning dip in India's Andaman Sea while Siamese crocodiles race in Thailand and surfers in Australia relish a perfect day. Monks in Bhutan run to dinner and a little girl in red stands out among white-robed women in an Indonesian mosque. Spanish youth decked in colorful, oversize papier-mâché heads celebrate a festival in Catalonia and a flower of flame blooms from a man's kerosene-filled mouth in a Sikh celebration in India.Around the globe, amazing moments are captured in time, from a spray of flash frozen petal fragments in California to a truck show of chrome-covered and gleaming neon rigs half the world away in Japan. Visions of Earth is a welcome escape from the news of natural disasters, conflict, political upheaval, and social unrest that fills our lives. The book delights our senses, ignites our emotions, and renews our optimism, showcasing the many ways that our world is a marvel to behold and a privilege to call home.

    It features all the great names in science, including Pythagoras, Galileo, Newton, Darwin, and Einstein, as well as more recent contributors such as Rachel Carson, James Lovelock, and Stephen Hawking.This little book presents serious science simply, answering questions like:What is Pythagorean Theorem? What is the difference between circadian rhythms and the popular concept of biorhythms? What is Hawking’s Black Hole Theory? Who developed the World Wide Web?

    The author paves the way for readers to discover for themselves what entropy is, how it changes, and most importantly, why it always changes in one direction in a spontaneous process.

    Beginning near the speed of light and proceeding to explorations of space-time and curved spaces, "Introducing Relativity" plots a visually accessible course through the thought experiments that have given shape to contemporary physics. Scientists from Newton to Hawking add their unique contributions to this story, as we encounter Einstein's astounding vision of gravity as the curvature of space-time and arrive at the breathtakingly beautiful field equations. Einstein's legacy is reviewed in the most advanced frontiers of physics today - black holes, gravitational waves, the accelerating universe and string theory. This is a superlative, fascinating graphic account of Einstein's strange world and how his legacy has been built upon since.

    In his hallmark friendly style, he explores the universal impact of being the right size. By examining stories ranging from Alice in Wonderland to Gulliver's Travels, he shows that humans have always been fascinated by things big and small. Why then does size always reside on the fringes of science and never on the center stage? Why do biologists and others ponder size only when studying something else--running speed, life span, or metabolism? Why Size Matters, a pioneering book of big ideas in a compact size, gives size its due by presenting a profound yet lucid overview of what we know about its role in the living world. Bonner argues that size really does matter--that it is the supreme and universal determinant of what any organism can be and do. For example, because tiny creatures are subject primarily to forces of cohesion and larger beasts to gravity, a fly can easily walk up a wall, something we humans cannot even begin to imagine doing.Bonner introduces us to size through the giants and dwarfs of human, animal, and plant history and then explores questions including the physics of size as it affects biology, the evolution of size over geological time, and the role of size in the function and longevity of living things.As this elegantly written book shows, size affects life in its every aspect. It is a universal frame from which nothing escapes.

    His work won him the Nobel Prize in 1922 and his ideas continue to propel physics towards new discoveries. But what is quantum theory? Most of us do not understand even the basics of one of the most significant scientific advances ever made, opening up a whole new field in science, whose ambiguities still challenge scientists around the world.Bohr and Quantum Theory offers an accessible and absorbing account of the man who was both a part of The Manhattan Project but also an advocate of peace.He held the key to understanding such intricate realities as black holes and nuclear energy. Bohr's Big Idea explains complex and crucial ideas in a clear and engaging way, placing quantum theory in the context of a man's life, work and time and examining its important implications for our future.The Big Idea series is a fascinating look at the greatest advances in our scientific history, and at the men and women who made these fundamental breakthroughs.
