And before there were fish in the sea, there were cephalopods - the ancestors of modern squid and Earth’s first truly substantial animals. Cephalopods became the first creatures to rise from the seafloor, essentially inventing the act of swimming. With dozens of tentacles and formidable shells, they presided over an undersea empire for millions of years. But when fish evolved jaws, the ocean’s former top predator became its most delicious snack. Cephalopods had to step up their game. Many species streamlined their shells and added defensive spines, but these enhancements only provided a brief advantage. Some cephalopods then abandoned the shell entirely, which opened the gates to a flood of evolutionary innovations: masterful camouflage, fin-supplemented jet propulsion, perhaps even dolphin-like intelligence. Squid Empire is an epic adventure spanning hundreds of millions of years, from the marine life of the primordial ocean to the calamari on tonight’s menu. Anyone who enjoys the undersea world—along with all those obsessed with things prehistoric—will be interested in the sometimes enormous, often bizarre creatures that ruled the seas long before the first dinosaurs.

    Now he makes the case that living on Mars is not just plausible, but inevitable.It sounds like science fiction, but Stephen Petranek considers it fact: Within twenty years, humans will live on Mars. We'll need to. In this sweeping, provocative book that mixes business, science, and human reporting, Petranek makes the case that living on Mars is an essential back-up plan for humanity and explains in fascinating detail just how it will happen.The race is on. Private companies, driven by iconoclastic entrepreneurs, such as Elon Musk, Jeff Bezos, Paul Allen, and Sir Richard Branson; Dutch reality show and space mission Mars One; NASA; and the Chinese government are among the many groups competing to plant the first stake on Mars and open the door for human habitation. Why go to Mars? Life on Mars has potential life-saving possibilities for everyone on earth. Depleting water supplies, overwhelming climate change, and a host of other disasters — from terrorist attacks to meteor strikes — all loom large. We must become a space-faring species to survive. We have the technology not only to get humans to Mars, but to convert Mars into another habitable planet. It will likely take 300 years to "terraform" Mars, as the jargon goes, but we can turn it into a veritable second Garden of Eden. And we can live there, in specially designed habitations, within the next twenty years.In this exciting chronicle, Petranek introduces the circus of lively characters all engaged in a dramatic effort to be the first to settle the Red Planet. How We'll Live on Mars brings firsthand reporting, interviews with key participants, and extensive research to bear on the question of how we can expect to see life on Mars within the next twenty years.

    Here he tackles all the "big questions," including the biggest of them all: Why does the universe seem so well adapted for life? In his characteristically clear and elegant style, Davies shows how recent scientific discoveries point to a perplexing fact: many different aspects of the cosmos, from the properties of the humble carbon atom to the speed of light, seem tailor-made to produce life. A radical new theory says it's because our universe is just one of an infinite number of universes, each one slightly different. Our universe is bio-friendly by accident -- we just happened to win the cosmic jackpot. While this "multiverse" theory is compelling, it has bizarre implications, such as the existence of infinite copies of each of us and Matrix-like simulated universes. And it still leaves a lot unexplained. Davies believes there's a more satisfying solution to the problem of existence: the observations we make today could help shape the nature of reality in the remote past. If this is true, then life -- and, ultimately, consciousness -- aren't just incidental byproducts of nature, but central players in the evolution of the universe. Whether he's elucidating dark matter or dark energy, M-theory or the multiverse, Davies brings the leading edge of science into sharp focus, provoking us to think about the cosmos and our place within it in new and thrilling ways.

    At his side, a mysterious woman whose life and memory he saved, whose love he has won for a second time. His name is Derec; hers is Ariel. And their story has only begun to be told...In Robot City, the late science fiction genius Isaac Asimov challenged a talented group of science fiction writers to resolve the conundrums he set for them in the context of his famous Three Laws of Robotics. In Robots and Aliens, a new challenge was put forth: What would happen if the robots of Asimov's universe were to meet alien races? Would the Three Laws that protect both humans and robots still apply when dealing with a species that is neither...?This pair of adventures, enhanced with a pair of essays by Asimov himself, continue the saga of Robot City, where the finest minds in science fiction enter the most futuristic landscape in robot history!

    The book takes us from the Greeks' earliest scientific observations through Einstein and beyond in an inspiring celebration of human curiosity. It ends with the quest for the Higgs boson, nicknamed the God Particle, which scientists hypothesize will help unlock the last secrets of the subatomic universe. With a new preface by Lederman, The God Particle will leave you marveling at our continuing pursuit of the infinitesimal.

    

    The book's lexicon is limited to the thousand most common words in the English language, excluding physics, energy, galaxy, or even universe. Through the eyes of a fictional scientist (Student-People) hunting for dark matter with one of the biggest telescopes (Big-Seers) on Earth (Home-World), cosmologist Roberto Trotta explores the most important ideas about our universe (All-there-is) in language simple enough for anyone to understand. A unique blend of literary experimentation and science popularization, this delightful book is a perfect gift for any aspiring astronomer. The Edge of the Sky tells the story of the universe on a human scale, and the result is out of this world.

    A strong gravitational wave will briefly change that distance by less than the thickness of a human hair. We have perhaps less than a few tenths of a second to perform this measurement. And we don’t know if this infinitesimal event will come next month, next year or perhaps in thirty years.In 1916 Einstein predicted the existence of gravitational waves: miniscule ripples in the very fabric of spacetime generated by unfathomably powerful events. If such vibrations could somehow be recorded, we could observe our universe for the first time through sound: the hissing of the Big Bang, the whale-like tunes of collapsing stars, the low tones of merging galaxies, the drumbeat of two black holes collapsing into one. For decades, astrophysicists have searched for a way of doing so…In 2016 a team of hundreds of scientists at work on a billion-dollar experiment made history when they announced the first ever detection of a gravitational wave, confirming Einstein’s prediction. This is their story, and the story of the most sensitive scientific instrument ever made: LIGO.Based on complete access to LIGO and the scientists who created it, Black Hole Blues provides a firsthand account of this astonishing achievement: a compelling, intimate portrait of cutting-edge science at its most awe-inspiring and ambitious.

    Yet this is now an established scientific fact. In The Universe Next Door, science writer Marcus Chown examines a dozen mind-bending new ideas that also fly in the face of reason--but that, according to eminent scientists, might just be crazy enough to be true. Could time run backwards? Is there a fifth dimension? Does quantum theory promise immortality? To explore these questions, Chown has interviewed some of the most imaginative and courageous people working at the forefront of science, and he has come away with a smorgasbord of mind-expanding ideas. For instance, Lawrence Schulman at New York's Clarkson University believes there could be regions in our Universe where stars unexplode, eggs unbreak and living things grow younger with every passing second. Max Tegmark, at the University of Pennsylvania, believes there could be an infinity of realities stacked together like the pages of a never-ending book (with an infinite number of versions of you, living out an infinite number of different lives). And David Stevenson of Cal Tech argues that life may exist on worlds drifting in the cold, dark abyss between the stars, worlds without suns to warm them. Indeed, these worlds may be the most common sites for life in the universe. Was our universe created by super-intelligent beings from another universe? Is there evidence of extraterrestrial life lying right beneath our feet? The Universe Next Door ponders these and many other thought-provoking questions. You may not agree with all the answers but your head will be spinning by the time you reach the last page.
