And as we discover countless exoplanets orbiting other stars—among them, rocky super-Earths and gaseous Hot Jupiters—we become ever more hopeful that we may come across extraterrestrial life. Yet even as we become aware of the vast numbers of planets outside our solar system, it has also become clear that Earth is exceptional. The question is: why?In Lucky Planet, astrobiologist David Waltham argues that Earth’s climate stability is one of the primary factors that makes it able to support life, and that nothing short of luck made such conditions possible. The four-billion-year stretch of good weather that our planet has experienced is statistically so unlikely, he shows, that chances are slim that we will ever encounter intelligent extraterrestrial others.Describing the three factors that typically control a planet’s average temperature—the heat received from its star, how much heat the planet absorbs, and the concentration of greenhouse gases in the atmosphere—Waltham paints a complex picture of how special Earth’s climate really is. He untangles the mystery of why, although these factors have shifted by such massive measures over the history of life on Earth, surface temperatures have never fluctuated so much as to make conditions hostile to life. Citing factors such as the size of our Moon and the effect of an ever-warming Sun, Waltham challenges the prevailing scientific consensus that other Earth-like planets have natural stabilizing mechanisms that allow life to flourish.A lively exploration of the stars above and the ground beneath our feet, Lucky Planet seamlessly weaves the story of Earth and the worlds orbiting other stars to give us a new perspective of the surprising role chance plays in our place in the universe.

    Now in it's tenth edition, this text makes chemistry exciting to students by showing them why important concepts are relevant to their lives and future careers.

    Today, more than sixty years later, members of a new generation of scientists are attempting to create life from the ground up. Science has moved forward in leaps and bounds since Schrodinger's time, but our understanding of what does and does not constitute life has only grown more complex. An era that has already seen computer chip-implanted human brains, genetically engineered organisms, genetically modified foods, cloned mammals, and brain-dead humans kept alive by machines is one that demands fresh thinking about the concept of life. While a segment of our national debate remains stubbornly mired in moral quandaries over abortion, euthanasia, and other right to life issues, the science writer Ed Regis demonstrates how science can and does provide us with a detailed understanding of the nature of life. Written in a lively and accessible style, and synthesizing a wide range of contemporary research, What Is Life? is a brief and illuminating contribution to an age-old debate.

    This book tells the version according to modern science. It is a unique account, starting at the Big Bang and traveling right up to the emergence of humans as conscious intelligent beings, 13.8 billion years later. Chapter by chapter, it sets out the current state of scientific knowledge: the origins of space and time; energy, mass, and light; galaxies, stars, and our sun; the habitable earth, and complex life itself. Drawing together the physical and biological sciences, Baggott recounts what we currently know of our history, highlighting the questions science has yet to answer.

    It infected nearly one-third of the world’s population and killed ten percent of those it struck. In its wake, schools and businesses closed, hospitals became overwhelmed, and the sick spilled out into makeshift care centers in public spaces. Policemen, public transportation workers, and everyday citizens in face masks were a common—and eerie—sight. Yet, discussion of this global pandemic often takes a backseat to World War I and other contemporary events.

    It lies at the core of chemistry and embodies the most fundamental principles of the field. The one definitive text on the development of the periodic table by van Spronsen (1969), has been out of print for a considerable time.The present book provides a successor to van Spronsen, but goes further in giving an evaluation of the extent to which modern physics has, or has not, explained the periodic system. The book is written in a lively style to appeal to experts and interested lay-persons alike.The Periodic Table begins with an overview of the importance of the periodic table and of the elements and it examines the manner in which the term 'element' has been interpreted by chemists and philosophers. The book then turns to a systematic account of the early developments that led to theclassification of the elements including the work of Lavoisier, Boyle and Dalton and Cannizzaro. The precursors to the periodic system, like D�bereiner and Gmelin, are discussed. In chapter 3 the discovery of the periodic system by six independent scientists is examined in detail.Two chapters are devoted to the discoveries of Mendeleev, the leading discoverer, including his predictions of new elements and his accommodation of already existing elements. Chapters 6 and 7 consider the impact of physics including the discoveries of radioactivity and isotopy and successivetheories of the electron including Bohr's quantum theoretical approach. Chapter 8 discusses the response to the new physical theories by chemists such as Lewis and Bury who were able to draw on detailed chemical knowledge to correct some of the early electronic configurations published by Bohr andothers.Chapter 9 provides a critical analysis of the extent to which modern quantum mechanics is, or is not, able to explain the periodic system from first principles. Finally, chapter 10 considers the way that the elements evolved following the Big Bang and in the interior of stars. The book closeswith an examination of further chemical aspects including lesser known trends within the periodic system such as the knight's move relationship and secondary periodicity, as well at attempts to explain such trends.

    It includes: Two full-length exams that follow the content and style of the new AP exam All test questions answered and explained An extensive review covering all AP test topics Hundreds of additional multiple-choice and free-response practice questions with answer explanations

    "It would be hard to design a more reliable timekeeper." In Nature's Clocks, Macdougall tells how scientists who were seeking to understand the past arrived at the ingenious techniques they now use to determine the age of objects and organisms. By examining radiocarbon (C-14) dating—the best known of these methods—and several other techniques that geologists use to decode the distant past, Macdougall unwraps the last century's advances, explaining how they reveal the age of our fossil ancestors such as "Lucy," the timing of the dinosaurs' extinction, and the precise ages of tiny mineral grains that date from the beginning of the earth's history. In lively and accessible prose, he describes how the science of geochronology has developed and flourished. Relating these advances through the stories of the scientists themselves—James Hutton, William Smith, Arthur Holmes, Ernest Rutherford, Willard Libby, and Clair Patterson—Macdougall shows how they used ingenuity and inspiration to construct one of modern science's most significant accomplishments: a timescale for the earth's evolution and human prehistory.

    Your life, your thoughts, your diseases, and your health are all the function of cells.But what do you really know about what goes on inside you?The last time most people thought about cells in any detail was probably in high school or a college general biology class. But the field of cell biology has advanced incredibly rapidly in recent decades, and a great deal of what we may have learned in high school and college is no longer accurate or particularly relevant.The Cell: Inside the Microscopic World that Determines Our Health, Our Consciousness, and Our Future is a fascinating story of the incredible complexity and dynamism inside the cell and of the fantastic advancements in our understanding of this microscopic world.Dr. Joshua Z. Rappoport is at the forefront of this field, and he will take you on a journey to discover:A deeper understanding of how cells work and the basic nature of life on earth.Fascinating histories of some of the key discoveries from the seventeenth century to the last decade and provocative thoughts on the current state of academic research.The knowledge required to better understand the new developments that are announced almost weekly in science and health care, such as cancer, cellular therapies, and the potential promise of stem cells.The ability to make better decisions about health and to debunk the misinformation that comes in daily via media.Using the latest scientific research, The Cell illustrates the diversity of cell biology and what it all means for your everyday life.

    Now, for the first time, journalist and geologist Chris Turney explains to the non-specialist exactly how archaeologists, paleontologists, and geologists "tell the time". Each chapter explores one famous event or object from the past, walking readers step by step through the detective work used to determine when things happened. From the Ice Age to the pyramids, from human evolution to the Shroud of Turin, Turney reveals how written records, carbon, pollen, constellations, DNA sequencing, and more all play a part in solving the mystery of the true age of objects and events. As we struggle to manage current environmental threats and conservation troubles, we ignore or misunderstand these techniques and their results at our peril.

    They wanted to discover how the world worked, but they also wanted credit for making those discoveries, and their personalities often affected how that credit was assigned. Gilbert Lewis, for example, could be reclusive and resentful, and his enmity with Walther Nernst may have cost him the Nobel Prize; Irving Langmuir, gregarious and charming, rediscovered Lewis's theory of the chemical bond andreceived much of the credit for it. Langmuir's personality smoothed his path to the Nobel Prize over Lewis.Coffey deals with moral and societal issues as well. These same scientists were the first to be seen by their countries as military assets. Fritz Haber, dubbed the father of chemical warfare, pioneered the use of poison gas in World War I-vividly described-and Glenn Seaborg and Harold Urey wereleaders in World War II's Manhattan Project; Urey and Linus Pauling worked for nuclear disarmament after the war. Science was not always fair, and many were excluded. The Nazis pushed Jewish scientists like Haber from their posts in the 1930s. Anti-Semitism was also a force in American chemistry, and few women were allowed in; Pauling, for example, used his influence to cut off the funding and block the publications of his rival, Dorothy Wrinch.Cathedrals of Science paints a colorful portrait of the building of modern chemistry from the late 19th to the mid-20th century.
