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.

    However, while physicists celebrated these momentous discoveries—which presaged the era of big science and nuclear bombs—Europe was moving inexorably toward totalitarianism and war. In April of that year, about forty of the world’s leading physicists—including Werner Heisenberg, Lise Meitner, and Paul Dirac—came to Niels Bohr’s Copenhagen Institute for their annual informal meeting about the frontiers of physics. Physicist Gino Segrè brings to life this historic gathering, which ended with a humorous skit based on Goethe’s Faust—a skit that eerily foreshadowed events that would soon unfold. Little did the scientists know the Faustian bargains they would face in the near future. Capturing the interplay between the great scientists as well as the discoveries they discussed and debated, Segrè evokes the moment when physics—and the world—was about to lose its innocence.

    Isolated and desolate, they were largely overlooked by early explorers until Charles Darwin arrived there in the 1830s. It was Darwin who recognized that Galapagos' isolation and desolation were advantages: the paucity of species and lack of outside influences made the workings of natural selection crystal clear. Since then, every important advance and controversy in evolutionary thinking has had its reflection on the Galapagos. In every sense-intellectually, institutionally, and culturally-the history of science on these islands is a history of the way evolutionary science was done for the past 150 years. Evolution's Workshop tells the story of Darwin's explorations there; the fabulous Gilded Age expeditions, run from rich men's gigantic yachts, that featured rough-and-ready science during the day and black-tie dinners every night; the struggle for control of research on the Galapagos; the current efforts by "creation scientists" to use the Galapagos to undercut evolutionary teaching; and many other compelling stories.

    From the very first attempts by the Greeks to grapple with the complexities of our known world to the latest application of infinity in physics, The Road to Reality carefully explores the movement of the smallest atomic particles and reaches into the vastness of intergalactic space. Here, Penrose examines the mathematical foundations of the physical universe, exposing the underlying beauty of physics and giving us one the most important works in modern science writing.

    The consequences of this gathering may be enormous. In this new ebook, experts Patrick J. Michaels and Paul C. Knappenberger assess the issues sure to drive the debate before, during, and after the Paris meeting.

    He was a city boy, unsure of what lay ahead. When he entered the forest, which would go on to become one of the last strongholds of wild tigers, it had a profound effect on him, changing his life forever.For the next forty years, he studied nearly 200 Ranthambhore tigers, spending every waking moment in close proximity to these magnificent animals. Of the various tigers he observed a handful became extra special, and it is these which come to glorious life in this book. They include Padmini, the Queen Mother, the first tiger the author got to know well; Genghis, the master predator, who invented a way of killing prey in water, the first time this had been observed anywhere in the world; Noon, one of his all-time favourites, who received her name because she was most active in the middle of the day; Broken Tooth, an exceptionally gentle male; Laxmi, a devoted mother, whose methods of raising her cubs revolutionized tiger studies; Machli, the most famous tigress in Ranthambhore, and several more.

    Drawing on decades of stargazing experience, the authors suggest what equipment to buy and what to avoid, describe observing techniques, and explain how to hunt down the most interesting celestial objects. Each chapter is illustrated with the latest, breathtaking astrophotography.This companion is broken down into three parts: "Equipment for Backyard Astronomy", "Observing the Celestial Panorama" and "Astrophotography". It focuses on the practical aspects of astronomy.Among many astronomy subjects, the authors offer advice on how to contend with light pollution, and how to take successful and impressive color photographs of galaxies and nebulas (with or without a telescope). Each chapter is written in clear, jargon-free yet detailed.

    A total eclipse of the Sun will be visible from within a narrow corridor that traverses the United States. The path of the Moon's umbral shadow will begin in the northern Pacific and cross the USA from west to east from Oregon to South Carolina. The Moon's penumbral shadow will produce a partial eclipse visible from most of North America. In fact, the 2017 full eclipse is such an important sky event that sky watchers in Europe are already planning trips to view it. 2017 Guide to the Night Sky provides all of the information needed to view this exciting eclipse and track its path. The time zones and transit of the eclipse will be noted inside the book's jacket for quick and easy reference.The night sky makes for exciting viewing any time of the year, and 2017 Guide to the Night Sky is the ideal guide to help amateur astronomers find their way for the entire 12 months. With monthly charts and other diagrams set for a latitude of 40 degrees North, it shows how the visible stars change from month to month and includes the many sky events that occur throughout the year. It is highly practical for beginning sky gazers because the objects and events may be observed with the naked eye, or nothing more complicated than a pair of binoculars.The month-by-month guides include sky activity charts and moon calendars; meteors (with dates of showers, including hourly rate of radiants); the Planets; ecliptic charts; diagrams of interesting events; plus sky and constellation maps throughout.An appendix includes a full glossary; the Greek Alphabet; the constellation genitives, abbreviations and English names; a table of common asterisms; further information; recommended astronomy journals, societies, institutions and organizations; software, and internet sources.Especially useful for beginning sky watchers, this guide will be fully updated to 2017. Its small and light format makes it the ideal portable reference for backyard astronomers.

    The answers to the big questions: Are the laws of physics fine-tuned for life? Are we alone in the universe? Why is gravity so weak? How can I predict the winner of every horse race?

    Even as a teenager, experimenting in his own laboratory, he was impressed by the logic and materiality of the universe, which is governed by a small number of disembodied forces and laws. Those laws decree that all things in the world are material and impermanent. But one summer evening, while looking at the stars from a small boat at sea, Lightman was overcome by the overwhelming sensation that he was merging with something larger than himself--a grand and eternal unity, a hint of something absolute and immaterial. Searching for Stars on an Island in Maine is the result of these seemingly contradictory impulses, written as an extended meditation on an island in Maine, where Lightman and his wife spend their summers. Framing the dialogue between religion and science as a contrast between absolutes and relatives, Lightman explores our human quest for truth and meaning and the different methods of religion and science in that quest. Along the way, he draws from sources ranging from St. Augustine's conception of absolute truth to Einstein's relativity, from a belief in the divine and eternal nature of stars to their discovered materiality and mortality, from the unity of the once indivisible atom to the multiplicity of subatomic particles and the recent notion of multiple universes. What emerges is not only an understanding of the encounter between science and religion but also a profound exploration of the complexity of human existence.

    What is a tree? Why are they so important to life on Earth? How do they eat, breathe, grow, communicate, and regenerate themselves? How many different kinds of trees are there, and where do they live?

    Taking as territory everything from the Big Bang to the rise of civilization, Bryson seeks to understand how we got from there being nothing at all to there being us. To that end, he has attached himself to a host of the world’s most advanced (and often obsessed) archaeologists, anthropologists, and mathematicians, travelling to their offices, laboratories, and field camps. He has read (or tried to read) their books, pestered them with questions, apprenticed himself to their powerful minds. A Short History of Nearly Everything is the record of this quest, and it is a sometimes profound, sometimes funny, and always supremely clear and entertaining adventure in the realms of human knowledge, as only Bill Bryson can render it. Science has never been more involving or entertaining.
