This essay by Copernicus (1473-1543), revolutionized the way we look at the earth's placement in the universe, and paved the way for many great scientists, including Galileo and Isaac Newton, whose theories stemmed from this model. Featuring a biography of Copernicus and an accessible, enlightening introduction, both written by the renowned physicist Stephen Hawking, On the Revolution of Heavenly Spheres provides a fascinating look at the theories which shaped our modern understanding of astronomy and physics.

    This volume contains two of his most important works: The Epitome of Copernican Astronomy (books 4 and 5 of which are translated here) is a textbook of Copernican science, remarkable for the prominence given to physical astronomy and for the extension to the Jovian system of the laws recently discovered to regulate the motions of the Planets. Harmonies of the World (book 5 of which is translated here) expounds an elaborate system of celestial harmonies depending on the varying velocities of the planets.

    Heath's translation of the thirteen books of Euclid's Elements. In keeping with Green Lion's design commitment, diagrams have been placed on every spread for convenient reference while working through the proofs; running heads on every page indicate both Euclid's book number and proposition numbers for that page; and adequate space for notes is allowed between propositions and around diagrams. The all-new index has built into it a glossary of Euclid's Greek terms.Heath's translation has stood the test of time, and, as one done by a renowned scholar of ancient mathematics, it can be relied upon not to have inadvertantly introduced modern concepts or nomenclature. We have excised the voluminous historical and scholarly commentary that swells the Dover edition to three volumes and impedes classroom use of the original text. The single volume is not only more convenient, but less expensive as well.

    Remarkable for his range of thought and his mastery of treatment, Archimedes addressed such topics as the famous problems of the ratio of the areas of a cylinder and an inscribed sphere; the measurement of a circle; the properties of conoids, spheroids, and spirals; and the quadrature of the parabola. This edition offers an informative introduction with many valuable insights into the ancient mathematician's life and thought as well as the views of his contemporaries. Modern mathematicians, physicists, science historians, and logicians will find this volume a source of timeless fascination.

    His public advocacy of the Copernican over the Aristotelian system of the universe flew directly in the face of biblical authority and ecclesiastical tradition. Condemned and placed under house arrest by the Inquisition, Galileo nonetheless devoted his last years to the completion of his Dialogues Concerning Two New Sciences, which deals with motion and the resistance of solids. The Two New Sciences, which Galileo called his most important work, may be regarded as the summary statement of a life devoted to scientific experimentation and free inquiry untrammeled by tradition and authority.

    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.

    Now, in the first translation into English since 1930, Aristotle's thought is presented accurately, with a lucid introduction and extensive notes to explain the general structure of each section of the book, and shed light on particular problems. It simplifies and expands the style of the original, making for easier reading and better comprehension.

    His fame was such that many Greek medical writings became attributed to him. What they have in common is not dogma but, rather, constructive debate between one another. They also share a concern with meticulous observation and an insistence on physical, not supernatural, causation of illness. The writers were the pioneers of rational medicine; their ideas, dominant for centuries, still reveal to us the ideal of ethical practice, as well as the origins not just of Western medicine but of scientific method.This excellent selection of Hippocratic treatises shows the range of writing and thought. Some are technical works on embryology, surgery or anatomy; others are addressed to a lay audience; all are informed with the spirit of inquiry. G.E.R. Lloyd's authoritative introduction puts them into their contemporary context and assesses their later influence.

    In what is by far his most famous and influential work, Plutarch reveals the character and personality of his subjects and how they led ultimately to tragedy or victory. Richly anecdotal and full of detail, Volume I contains profiles and comparisons of Romulus and Theseus, Numa and Lycurgus, Fabius and Pericles, and many more powerful figures of ancient Greece and Rome. The present translation, originally published in 1683 in conjunction with a life of Plutarch by John Dryden, was revised in1864 by the poet and scholar Arthur Hugh Clough, whose notes and preface are also included in this edition.

    Their dialogue covers many questions, such as: is knowledge purely subjective, composed of the ever-changing flow of impressions we receive from the outside world? Is it better thought of as 'true belief'? Or is it, as many modern philosophers argue, 'justified true belief', in which the belief is supported by argument or evidence? With skill and eloquence, Socrates guides the debate, drawing out the implications of these theories and subjecting them to merciless and mesmerising criticism. One of the founding works of epistemology, this profound discussion of the problem of knowledge continues to intrigue and inspire.

    Due to its age, it may contain imperfections such as marks, notations, marginalia and flawed pages. Because we believe this work is culturally important, we have made it available as part of our commitment for protecting, preserving, and promoting the world's literature in affordable, high quality, modern editions that are true to the original work.

    Having just completed his masterpiece, The General Theory of Relativity—which provided a brand-new theory of gravity and promised a new perspective on the cosmos as a whole—he set out at once to share his excitement with as wide a public as possible in this popular and accessible book.Here published for the first time as a Penguin Classic, this edition of Relativity features a new introduction by bestselling science author Nigel Calder.

    In his introductory essay, John Cooper explains the presentation of these works, discusses questions concerning the chronology of their composition, comments on the dialogue form in which Plato wrote, and offers guidance on approaching the reading and study of Plato's works.Also included are concise introductions by Cooper and Hutchinson to each translation, meticulous annotation designed to serve both scholar and general reader, and a comprehensive index. This handsome volume offers fine paper and a high-quality Smyth-sewn cloth binding in a sturdy, elegant edition.
