QED--the edited version of four lectures on quantum electrodynamics that Feynman gave to the general public at UCLA as part of the Alix G. Mautner Memorial Lecture series--is perhaps the best example of his ability to communicate both the substance and the spirit of science to the layperson.The focus, as the title suggests, is quantum electrodynamics (QED), the part of the quantum theory of fields that describes the interactions of the quanta of the electromagnetic field-light, X rays, gamma rays--with matter and those of charged particles with one another. By extending the formalism developed by Dirac in 1933, which related quantum and classical descriptions of the motion of particles, Feynman revolutionized the quantum mechanical understanding of the nature of particles and waves. And, by incorporating his own readily visualizable formulation of quantum mechanics, Feynman created a diagrammatic version of QED that made calculations much simpler and also provided visual insights into the mechanisms of quantum electrodynamic processes.In this book, using everyday language, spatial concepts, visualizations, and his renowned "Feynman diagrams" instead of advanced mathematics, Feynman successfully provides a definitive introduction to QED for a lay readership without any distortion of the basic science. Characterized by Feynman's famously original clarity and humor, this popular book on QED has not been equaled since its publication.

    So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in tasty chapters consumable anytime and anywhere in your busy day.

    Building on this advantage is the most detailed glossary in any student edition, one which offers unparalleled definition and explication of Aristotle's terminology and makes clear the correspondence between Greek terms and their renderings. The editors' extensive notes, also co-ordinated with the glossary, suggest alternative translations of problematic passages, discuss Aristotles argument, and elucidate difficult passages.

    Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria. Worse, these "too good to not be true" theories are actually untestable and they have left the field in a cul-de-sac. To escape, physicists must rethink their methods. Only by embracing reality as it is can science discover the truth.

    In this masterly synthesis, Arthur Koestler cuts through the sterile distinction between 'sciences' and 'humanities' to bring to life the whole history of cosmology from the Babylonians to Newton. He shows how the tragic split between science and religion arose and how, in particular, the modern world-view replaced the medieval world-view in the scientific revolution of the seventeenth century. He also provides vivid and judicious pen-portraits of a string of great scientists and makes clear the role that political bias and unconscious prejudice played in their creativity.

    The theme of Heisenberg's exposition is that words and concepts familiar in daily life can lose their meaning in the world of relativity and quantum physics. This in turn has profound philosophical implications for the nature of reality and for our total world view.

    Falling bodies fall with predictable accelerations. Eclipses can be accurately forecast centuries in advance. Nuclear power plants generate electricity according to well-known formulas. But those examples are the tip of the iceberg. In Nature's Numbers, Ian Stewart presents many more, each charming in its own way.. Stewart admirably captures compelling and accessible mathematical ideas along with the pleasure of thinking of them. He writes with clarity and precision. Those who enjoy this sort of thing will love this book."—Los Angeles Times

    The meeting -- which lasted ten minutes -- did not go well. Their loud and aggressive confrontation became the stuff of instant legend, but precisely what happened during that brief confrontation remained for decades the subject of intense disagreement.An engaging mix of philosophy, history, biography, and literary detection, Wittgenstein's Poker explores, through the Popper/Wittgenstein confrontation, the history of philosophy in the twentieth century. It evokes the tumult of fin-de-siécle Vienna, Wittgentein's and Popper's birthplace; the tragedy of the Nazi takeover of Austria; and postwar Cambridge University, with its eccentric set of philosophy dons, including Bertrand Russell. At the center of the story stand the two giants of philosophy themselves -- proud, irascible, larger than life -- and spoiling for a fight.

    The present volume is an outgrowth of that seminar, which dealt with the philosophical foundations of physics. Edited by Martin Gardner from transcripts of Carnap's classroom lectures and discussions, the book remains one of the clearest and soundest introductions to the philosophy of science.Specially designed to appeal to a wide range of readers, An Introduction to thePhilosophy of Science offers accessible coverage of such topics as laws and probability, measurement and quantitative language, the structure of space, causality and determinism, theoretical laws and concepts and much more. Stimulating and thought-provoking, the text will be of interest to philosophers, scientists and anyone interested in logical analysis of the concepts, statements and theories of science. Its clear and readable style help make it "the best book available for the intelligent reader who wants to gain some insight into the nature of contemporary philosophy of science" ― Choice. Foreword to the Basic Books Paperback Edition, 1974 (Gardner); Preface (Carnap); Foreword to the Dover Edition (Gardner). 35 black-and-white illustrations. Bibliography.

    Henry Bergson (1859-1941) was awarded the Nobel Prize in 1927. His works include Time & Free Will, An Introduction to Metaphysics, Creative Evolution & The Creative Mind.

    In contrast, Karl Popper's seminal book "The Logic of Scientific Discovery" has lapsed into relative obscurity. Although the two men debated the nature of science only once, the legacy of this encounter has dominated intellectual and public discussions on the topic ever since.Almost universally recognized as the modern watershed in the philosophy of science, Kuhn's relativistic vision of shifting paradigms--which asserted that science was just another human activity, like art or philosophy, only more specialized--triumphed over Popper's more positivistic belief in science's revolutionary potential to falsify society's dogmas. But has this victory been beneficial for science? Steve Fuller argues that not only has Kuhn's dominance had an adverse impact on the field but both thinkers have been radically misinterpreted in the process. This debate raises a vital question: Can science remain an independent, progressive force in society, or is it destined to continue as the technical wing of the military-industrial complex? Drawing on original research--including the Kuhn archives at MIT--Fuller offers a clear account of "Kuhn vs. Popper" and what it will mean for the future of scientific inquiry.

    In Gravity, he takes an enlightening look at three of the towering figures of science who unlocked many of the mysteries behind the laws of physics: Galileo, the first to take a close look at the process of free and restricted fall; Newton, originator of the concept of gravity as a universal force; and Einstein, who proposed that gravity is no more than the curvature of the four-dimensional space-time continuum.Graced with the author's own drawings, both technical and fanciful, this remarkably reader-friendly book focuses particularly on Newton, who developed the mathematical system known today as the differential and integral calculus. Readers averse to equations can skip the discussion of the elementary principles of calculus and still achieve a highly satisfactory grasp of a fascinating subject.Starting with a chapter on Galileo’s pioneering work, this volume devotes six chapters to Newton's ideas and other subsequent developments and one chapter to Einstein, with a concluding chapter on post-Einsteinian speculations concerning the relationship between gravity and other physical phenomena, such as electromagnetic fields.

    Although deeply influenced by Einstein, he was also, more unusually for a scientist, inspired by mysticism. Indeed, in the 1970s and 1980s he made contact with both J. Krishnamurti and the Dalai Lama whose teachings helped shape his work. In both science and philosophy, Bohm's main concern was with understanding the nature of reality in general and of consciousness in particular. In this classic work he develops a theory of quantum physics which treats the totality of existence as an unbroken whole. Writing clearly and without technical jargon, he makes complex ideas accessible to anyone interested in the nature of reality.

    An astonishing synthesis of literary criticism, philosophy, theology, the theory of law and classical scholarship, it is undoubtedly one of the most important texts in twentieth century philosophy. Looking behind the self-consciousness of science, he discusses the tense relationship between truth and methodology. In examining the different experiences of truth, he aims to "present the hermeneutic phenomenon in its fullest extent."

    Here the texts of two of Schr�dinger's most famous lecture series are made available again. In the first, entitled Nature and the Greeks, Schr�dinger offers a historical account of the scientific world picture. In the second, called Science and Humanism, he addresses fundamental questions about the link between scientific and spiritual matters. As Roger Penrose confirms, these are the profound thoughts of a great mind, and as relevant today as when they were first published in the 1950s.
