In The Origin and Development of the Quantum Theory, we address the behaviour of atoms and subatomic particles and peer into the scaffolding and instruction manuals of the Gods. Nobel Prize winning physicist Max Planck, despite a reputedly steady and conservative disposition, revolutionised his field and his work on black body radiation and his particular conclusions on Quanta remain on the cutting edge of theoretical physics. Atoms and subatomic particles emit thermal radiation but the extent to which this is from the violet portion of the spectrum varies, in this lecture, the reader can find out why.After a life in which he had already been fighting to see an upswing in the fortunes of his beleaguered nation, he gave this lecture to an assembly of his most distinguished colleagues in 1920 in Stockholm. In these pages you can find his inspiring words about the glory of a lofty goal being undimmed by initial failures. In a moment of fantastic success, this speech illustrates the truth of his theory, rising from the ashes of the First World War with a discovery which changed the way physicists think. The lecture theatre was full of the finest minds of the age, waiting with baited breath on the edge of their seats to hear a genius hold forth on what made the Universe run.As the great man himself said 'Whatever the answer to this question, there can be no doubt that science will some day master the dilemma'.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

    Many of the translations were done by Strachey himself; the rest were prepared under his supervision. The result was to place the Standard Edition in a position of unquestioned supremacy over all other existing versions. Newly designed in a uniform format, each new paperback in the Standard Edition opens with a biographical essay on Freud's life and work —along with a note on the individual volume—by Peter Gay, Sterling Professor of History at Yale.

    In addition, the wide range of Leibniz's work--letters, published papers, and fragments on a variety of philosophical, religious, mathematical, and scientific questions over a fifty-year period--heightens the challenge of preparing an edition of his writings in English translation from the French and Latin.

    It challenged the entire edifice of the philosophy and learning of Bacon's time, and left its mark on all subsequent discussions of scientific method. This volume presents a new translation of the text into modern English by Michael Silverthorne, together with an introduction by Lisa Jardine that sets the work in the context of Bacon's scientific and philosophical activities.

    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.

    Fortunately for posterity, some of Luther's loyal followers took note of his informal speeches.The Table Talk of Martin Luther consists of excerpts from the great reformer's conversations with his students and colleagues, in which he comments on life, the church, and the Bible. Collected by Antony Lauterbach and John Aurifaber, Luther's close associates, these absorbing anecdotes reveal the speaker's personality and wisdom. An informative introduction by editor Thomas S. Kepler describes the circumstances under which this book came into existence and the remarkable story of its initial translation into English. This text is based on the acclaimed English translation by the literary critic and essayist William Hazlitt.

    H. Hardy was one of this century's finest mathematical thinkers, renowned among his contemporaries as a 'real mathematician ... the purest of the pure'. He was also, as C. P. Snow recounts in his Foreword, 'unorthodox, eccentric, radical, ready to talk about anything'. This 'apology', written in 1940 as his mathematical powers were declining, offers a brilliant and engaging account of mathematics as very much more than a science; when it was first published, Graham Greene hailed it alongside Henry James's notebooks as 'the best account of what it was like to be a creative artist'. C. P. Snow's Foreword gives sympathetic and witty insights into Hardy's life, with its rich store of anecdotes concerning his collaboration with the brilliant Indian mathematician Ramanujan, his aphorisms and idiosyncrasies, and his passion for cricket. This is a unique account of the fascination of mathematics and of one of its most compelling exponents in modern times.

    Just as all men have not the same writing, so all men have not the same speech sounds, but the mental experiences, which these directly symbolize, are the same for all, as also are those things of which our experiences are the images. This matter has, however, been discussed in my treatise about the soul, for it belongs to an investigation distinct from that which lies before us.As there are in the mind thoughts which do not involve truth or falsity, and also those which must be either true or false, so it is in speech. For truth and falsity imply combination and separation. Nouns and verbs, provided nothing is added, are like thoughts without combination or separation; ‘man’ and ‘white’, as isolated terms, are not yet either true or false. In proof of this, consider the word ‘goat-stag.’ It has significance, but there is no truth or falsity about it, unless ‘is’ or ‘is not’ is added, either in the present or in some other tense.

    Emerson offers timeless meditations on the value of individual greatness, reconnecting readers with the everyday virtues of his “Representative Men”: Plato, in whose writings are contained “the culture of nations”; Emanuel Swedenborg, a “rich discoverer” who strove to unite the scientific and spiritual planes; Michel de Montaigne, “the frankest and honestest of all writers”; William Shakespeare, who “wrote the text of modern life”; Napoleon Bonaparte, who had the “virtues and vices” of common men writ large; and Johann Wolfgang von Goethe, who “in conversation, in calamity…finds new materials.”This Modern Library Paperback Classic reflects the author’s corrections for an 1876 reprinting.

    Their subjects include the components, function, and weight of the atmosphere; capillary attraction; the carbon content in oxygen and living bodies; respiration and its analogy to the burning of a candle; and much more. Numerous illustrations.

    He approaches his subject through a discussion of language, the relationships of truth to experience and an investigation into how knowledge of the structure of language helps our understanding of the structure of the world.This edition includes a new introduction by Thomas Baldwin, Clare College, Cambridge

    No English dictionary before it had devoted so much space to everyday words, been so thorough in its definitions, or illustrated usage by quoting from Shakespeare and other great writers. Johnson's was the dictionary used by Jane Austen and Charles Dickens, Wordsworth and Coleridge, the Brontës and the Brownings, Thomas Hardy and Oscar Wilde. This new edition, edited by David Crystal, will contain a selection from the original, offering memorable passages on subjects ranging from books and critics to dreams and ethics.

    The central concept of his philosophy is found in a careful discrimination between the awareness of objects independent of our perception and the awareness of essences attributed to objects by our mind, or between what Santayana calls the realm of existents and the realm of subsistents. Since we can never be certain that these attributes actually inhere in a substratum of existents, skepticism is established as a form of belief, but animal faith is shown to be a necessary quality of the human mind. Without this faith there could be no rational approach to the necessary problem of understanding and surviving in this world.Santayana derives this practical philosophy from a wide and fascinating variety of sources. He considers critically the positions of such philosophers as Descartes, Euclid, Hume, Kant, Parmenides, Plato, Pythagoras, Schopenhauer, and the Buddhist school as well as the assumptions made by the ordinary man in everyday situations. Such matters as the nature of belief, the rejection of classical idealism, the nature of intuition and memory, symbols and myth, mathematical reality, literary psychology, the discovery of essence, sublimation of animal faith, the implied being of truth, and many others are given detailed analyses in individual chapters.
