    But this book will help you to do something that humans have only recently understood how to do: to count to regions that no animal has ever reached. By the end of this book you'll be able to count to infinity... and beyond. On our way to infinity we'll discover how the ancient Babylonians used their bodies to count to 60 (which gave us 60 minutes in the hour), how the number zero was only discovered in the 7th century by Indian mathematicians contemplating the void, why in China going into the red meant your numbers had gone negative and why numbers might be our best language for communicating with alien life.But for millennia, contemplating infinity has sent even the greatest minds into a spin. Then at the end of the nineteenth century mathematicians discovered a way to think about infinity that revealed that it is a number that we can count. Not only that. They found that there are an infinite number of infinities, some bigger than others. Just using the finite neurons in your brain and the finite pages in this book, you'll have your mind blown discovering the secret of how to count to infinity.Do something amazing and learn a new skill thanks to the Little Ways to Live a Big Life books!

    By replacing equations with diagrams, the book allows non-specialist readers to fully understand the concepts in relativity without the slow, painful progress so often associated with a complicated scientific subject. It allows readers not only to know how relativity works, but also to intuitively understand it.

    In a short and unhappy life, he wrote many books and articles on literary, satirical, religious and psychological themes, but the diversity and idiosyncratic style of his writing have contributed to a misunderstanding of his ideas. In this book--the only introduction to the full range of Kierkegaard's thought--Patrick Gardiner demonstrates how Kierkegaard developed his ideas and examines his thoughts in light of the doctrines on society developed by his contemporaries Marx and Feuerbach. Finally, he assesses the profound importance of Kierkegaard's ideas on the development of modern ways of thinking.

    And yet it has excused, and even been thought to justify, the most reprehensible crimes. Why should this be? This Very Short Introduction explores this and other puzzling questions. Do we love someone for their virtue, their beauty, or their moral or other qualities? Are love's characteristic desires altruistic or selfish? Are there duties of love? What do the sciences - neuroscience, evolutionary and social psychology, and anthropology - tell us about love? Many of the answers we give to such questions are determined not so much by the facts of human nature as by the ideology of love. Ronald de Sousa considers some of the many paradoxes raised by love, looking at the different kinds of love - affections, affiliation, philia, storage, agape, but focusses on eros, or romantic love. He considers whether our conventional beliefs about love and sex are deeply irrational and argues that alternative conceptions of love and sex, although hard to formulate and live by, may be worth striving for. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

    The National Security Agency grew out of the legendary codebreaking programs of World War II that turned the tide of Allied victory by cracking the famed Enigma machine and other seemingly impenetrable German and Japanese codes. But things became murky in the postwar years, when our intelligence community found itself targeting not battlefield enemies, but suspected spies, foreign leaders, and even American citizens. Now Stephen Budiansky--a longtime expert in cryptology--tells the fascinating story of how the NSA came to be, and of its central, often fraught and controversial role in the major events of the Cold War, from the Korean War to the Cuban Missile Crisis to Vietnam and beyond. He also guides us through the fascinating challenges faced by cryptanalysts, and how they broke some of the most complicated codes of the twentieth century. A riveting, essential history of the underbelly of the Cold War.

    The First seven chapters deal with structure related aspects such as lattice and crystal structures, bonding, packing and diffusion of atoms followed by imperfections and lattice vibrations. Chapter eight deals mainly with experimental methods of determining structures of given materials. While the next nine chapters cover various physical properties of crystalline solids, the last chapter deals with the anisotropic properties of materials. This chapter has been added for benefit of readers to understand the crystal properties (anisotropic) in terms of some simple mathematical formulations such as tensor and matrix. New to the Second Edition: Chapter on: *Anisotropic Properties of Materials

    

    If these galaxies had always been travelling, he reasoned, then they must, at some point, have been on top of one another. This discovery transformed the debate about one of the most fundamental questions of human existence - how did the universe begin?Every society has stories about the origin of the cosmos and its inhabitants, but now, with the power to peer into the early universe and deploy the knowledge gleaned from archaeology, geology, evolutionary biology and cosmology, we are closer than ever to understanding where it all came from. In The Origin of (almost) Everything, New Scientist explores the modern origin stories of everything from the Big Bang, meteorites and dark energy, to dinosaurs, civilisation, timekeeping, belly-button fluff and beyond.From how complex life evolved on Earth, to the first written language, to how humans conquered space, The Origin of (almost) Everything offers a unique history of the past, present and future of our universe.span

    Writing with a focus on Christianity, David Ford provides a trenchant and balanced discussion of the study of faith and religion. He describes the development of the field of theology, and explores such issues as knowledge, community, worship, salvation, God, prayer, and evil. Ford also weaves the idea of the quest for wisdom into the entire fabric of his discussion, and concludes with a look ahead to the theology of the next century. Theology: A Very Short Introduction tackles the questions raised by and about religion in a thought-provoking and engaging manner. About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.
