    Even after more than three centuries and the revolutions of Einsteinian relativity and quantum mechanics, Newtonian physics continues to account for many of the phenomena of the observed world, and Newtonian celestial dynamics is used to determine the orbits of our space vehicles.This completely new translation, the first in 270 years, is based on the third (1726) edition, the final revised version approved by Newton; it includes extracts from the earlier editions, corrects errors found in earlier versions, and replaces archaic English with contemporary prose and up-to-date mathematical forms. Newton's principles describe acceleration, deceleration, and inertial movement; fluid dynamics; and the motions of the earth, moon, planets, and comets. A great work in itself, the Principia also revolutionized the methods of scientific investigation. It set forth the fundamental three laws of motion and the law of universal gravity, the physical principles that account for the Copernican system of the world as emended by Kepler, thus effectively ending controversy concerning the Copernican planetary system.The illuminating Guide to the Principia by I. Bernard Cohen, along with his and Anne Whitman's translation, will make this preeminent work truly accessible for today's scientists, scholars, and students.

    String theory has been called the "theory of everything." It seeks to describe all the fundamental forces of nature. It encompasses gravity and quantum mechanics in one unifying theory. But it is unproven and fraught with controversy. After reading this book, you'll be able to draw your own conclusions about string theory.Steve Gubser begins by explaining Einstein's famous equation "E = mc2," quantum mechanics, and black holes. He then gives readers a crash course in string theory and the core ideas behind it. In plain English and with a minimum of mathematics, Gubser covers strings, branes, string dualities, extra dimensions, curved spacetime, quantum fluctuations, symmetry, and supersymmetry. He describes efforts to link string theory to experimental physics and uses analogies that nonscientists can understand. How does Chopin's Fantasie-Impromptu relate to quantum mechanics? What would it be like to fall into a black hole? Why is dancing a waltz similar to contemplating a string duality? Find out in the pages of this book."The Little Book of String Theory" is the essential, most up-to-date beginner's guide to this elegant, multidimensional field of physics.

    This is a new view of mathematics, not the one we learned at school but a comprehensive guide to the patterns that recur through the universe and underlie human affairs. A Beginner's Guide to Constructing, the Universe shows you: Why cans, pizza, and manhole covers are round.Why one and two weren't considered numbers by the ancient Greeks.Why squares show up so often in goddess art and board games.What property makes the spiral the most widespread shape in nature, from embryos and hair curls to hurricanes and galaxies. How the human body shares the design of a bean plant and the solar system. How a snowflake is like Stonehenge, and a beehive like a calendar. How our ten fingers hold the secrets of both a lobster a cathedral, and much more.

    It hold the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

    G. Wells' 1895 classic The Time Machine, readers of science fiction have puzzled over the paradoxes of time travel. What would happen if a time traveler tried to change history? Would some force or law of nature prevent him? Or would his action produce a "new" history, branching away from the original?In the last decade of the twentieth century a group of theoretical physicists at the California Institute of Technology undertook a serious investigation of the possibility of pastward time travel, inspiring a serious and sustained study that engaged more than thirty physicists working at universities and institutes around the world.Many of the figures involved are familiar: Einstein, Stephen Hawking and Kip Thorne; others are names known mostly to physicists. These are the new time travelers, and this is the story of their work--a profoundly human endeavor marked by advances, retreats, and no small share of surprises. It is a fantastic journey to the frontiers of physics.

    Everything around us, including matter, is energy. A deep look into the mysteries of the subatomic world – the particles that make up the atom – provides answers to basic questions about how the universe works. To solve the future of mankind’s energy needs we need to understand the basic building blocks of the universe, including the atom and its parts. By exploring the subatomic world we’ll find more answers to our questions about time, forces like gravity and the matter that surrounds us. More importantly, we’ll find new ways to tap into the energy that exists around us to power our growing needs. In a new branch of particle physics, where tiny particles are thought of as energy waves, we find new answers that may help us in our quest to find alternative energy sources.

    And from the ancients who plotted its path at Stonehenge to the modern scientists who unraveled the nuclear fusion reaction that turns mass into energy, humankind has sought to solve its mysteries. In this lively biography of the sun, Bob Berman ranges from its stellar birth to its spectacular future death with a focus on the wondrous and enthralling, and on the heartbreaking sacrifice, laughable errors, egotistical battles, and brilliant inspirations of the people who have tried to understand its power. What, exactly, are the ghostly streaks of light astronauts see-but can't photograph-when they're in space? And why is it impossible for two people to see the exact same rainbow? Why are scientists beginning to think that the sun is safer than sunscreen? And how does the fluctuation of sunspots-and its heartbeat-affect everything from satellite communications to wheat production across the globe? Peppered with mind-blowing facts and memorable anecdotes about spectral curiosities-the recently-discovered "second sun" that lurks beneath the solar surface, the eerie majesty of a total solar eclipse-The Sun's Heartbeat offers a robust and entertaining narrative of how the Sun has shaped humanity and our understanding of the universe around us.

    Yet these creatures are our cousins. As fellow members of the animal kingdom—the Metazoa—they can teach us much about the evolutionary origins of not only our bodies, but also our minds.In his acclaimed 2016 book, Other Minds, the philosopher and scuba diver Peter Godfrey-Smith explored the mind of the octopus—the closest thing to an intelligent alien on Earth. In Metazoa, Godfrey-Smith expands his inquiry to animals at large, investigating the evolution of subjective experience with the assistance of far-flung species. As he delves into what it feels like to perceive and interact with the world as other life-forms do, Godfrey-Smith shows that the appearance of the animal body well over half a billion years ago was a profound innovation that set life upon a new path. In accessible, riveting prose, he charts the ways that subsequent evolutionary developments—eyes that track, for example, and bodies that move through and manipulate the environment—shaped the subjective lives of animals. Following the evolutionary paths of a glass sponge, soft coral, banded shrimp, octopus, and fish, then moving onto land and the world of insects, birds, and primates like ourselves, Metazoa gathers their stories together in a way that bridges the gap between mind and matter, addressing one of the most vexing philosophical problems: that of consciousness.Combining vivid animal encounters with philosophical reflections and the latest news from biology, Metazoa reveals that even in our high-tech, AI-driven times, there is no understanding our minds without understanding nerves, muscles, and active bodies. The story that results is as rich and vibrant as life itself.

    Members of the phylum Mollusca are among the most ancient animals on the planet. Their shells provide homes for other animals, and across the ages, people have used shells not only as trinkets but also as a form of money, and as powerful symbols of sex and death, prestige and war.The science and natural history of shells are woven into a compelling narrative, revealing their cultural importance and the ways they have been used by humans over the millennia. (Seashells have even been tapped as a source of mind-bending drugs.) Marine biologist Helen Scales shows how seashells have been sculpted by the fundamental rules of mathematics and evolution; how they gave us color, gems, food, and new medicines.After surviving multiple mass extinctions millions of years ago, molluscs and their shells still face an onslaught of anthropogenic challenges, including climate change and corrosive oceans. But rather than dwelling on all that is lost, Scales emphasizes that seashells offer an accessible way to reconnect people with nature, helping to bridge the gap between ourselves and the living world. Spirals in Time: The Secret Life and Curious Afterlife of Seashells shows why nature matters, and reveals the hidden wonders that you can hold in the palm of your hand.

    Most scientists didn't recognize the import of Hawking's claims, but Leonard Susskind and Gerard t'Hooft realized the threat, and responded with a counterattack that changed the course of physics.The Black Hole War is the thrilling story of their united effort to reconcile Hawking's revolutionary theories of black holes with their own sense of reality -- effort that would eventually result in Hawking admitting he was wrong, paying up, and Susskind and t'Hooft realizing that our world is a hologram projected from the outer boundaries of space.A brilliant book about modern physics, quantum mechanics, the fate of stars and the deep mysteries of black holes, Leonard Susskind's account of the Black Hole War is mind-bending and exhilarating reading.

    “A marvelously readable and level-headed explanation of basic science and how it relates to the issues.” —John Tierney, New York TimesThis is “must-have” information for all presidents—and citizens—of the twenty-first century: Is Iran’s nascent nuclear capability a genuine threat to the West? Are biochemical weapons likely to be developed by terrorists? Are there viable alternatives to fossil fuels that should be nurtured and supported by the government? Should nuclear power be encouraged? Can global warming be stopped?

     The Science Book covers every area of science--astronomy, biology, chemistry, geology, math, and physics, and brings the greatest scientific ideas to life with fascinating text, quirky graphics, and pithy quotes.

    But beyond the lore, meteorites tell an even greater story: that of our solar system. In Meteorite, geologist Tim Gregory shows that beneath the charred crusts of these celestial stones lies a staggering diversity of rock types. Their unique constituents, vibrant colors, and pungent smells contain thrilling tales of interstellar clouds, condensing stardust, and the fiery collisions of entire worlds. Gregory explores the world of meteorites to uncover new insights into what our solar system was like before our sun became a star, into the forging of our planet, and into the emergence of life on it. Humans have long looked to the skies for answers to big questions. Meteorite reveals how science is finally arriving at those answers.
