He was an essential figure in the development of philosophy, especially the Western tradition, and he founded the Academy in Athens, the first institution of higher learning in the Western world. Plato's dialogues have been used to teach a range of subjects, including philosophy, logic, ethics, rhetoric, religion and mathematics. His lasting themes include Platonic love, the theory of forms, the five regimes, innate knowledge, among others. His theory of forms launched a unique perspective on abstract objects, and led to a school of thought called Platonism. This collection contains the following works by Plato: Early Works • Apology • Charmides, or Temperance • Crito • Euthyphro • Gorgias • Hippias, Lesser • Hippias, Greater • Ion • Laches • Lysis • Protagoras Transitional Works • Cratylus • Euthydemus • Meno • Parmenides • Phaedo • Phaedrus • Symposium • The Republic Middle Works • Theaetetus Late Works • Critias • Laws • Philebus • Sophist • Statesman • Timaeus Works of Disputed Authorship • Alcibiades I & II • Eryxias • Menexenus • Theages

    -from Chapter One First published in 1944 and long a favorite of Tesla fans, this is a definitive biography of the man without whom modern civilization would not exist. Nikola Tesla, pioneer of electrical engineering, was a close friend of Pulitzer Prize-winning author O'Neill, and here, O'Neill captures the man as a scientist and as a public figure, exploring: . how Tesla's father inspired his life in engineering . why Tesla clung to his theories of electricity in the face of opposition . how the shy but newly popular Tesla navigated the social life of New York in the gay 1890s . Tesla's friendship with Mark Twain . the story of Tesla's lost Nobel Prize . Tesla's dabblings in the paranormal . and much more. JOHN JOSEPH O'NEILL (b. 1889) also wrote Engineering the New Age and You and the Universe: What Science Reveals.

    Topics range from ruminations on why Charles Dickens was among the best of writers and the worst of men to the haunting science fiction of J.G. Ballard; from the enduring legacies of Thomas Jefferson and George Orwell to the persistent agonies of anti-Semitism and jihad. Hitchens even looks at the recent financial crisis and argues for the enduring relevance of Karl Marx. The book forms a bridge between the two parallel enterprises of culture and politics. It reveals how politics justifies itself by culture, and how the latter prompts the former. In this fashion, Arguably burnishes Christopher Hitchens' credentials as (to quote Christopher Buckley) our "greatest living essayist in the English language."

    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.

    Michael Guillen, known to millions as the science editor of ABC's Good Morning America, tells the fascinating stories behind five mathematical equations. As a regular contributor to daytime's most popular morning news show and an instructor at Harvard University, Dr. Michael Guillen has earned the respect of millions as a clear and entertaining guide to the exhilarating world of science and mathematics. Now Dr. Guillen unravels the equations that have led to the inventions and events that characterize the modern world, one of which -- Albert Einstein's famous energy equation, E=mc2 -- enabled the creation of the nuclear bomb. Also revealed are the mathematical foundations for the moon landing, airplane travel, the electric generator -- and even life itself. Praised by Publishers Weekly as "a wholly accessible, beautifully written exploration of the potent mathematical imagination," and named a Best Nonfiction Book of 1995, the stories behind The Five Equations That Changed the World, as told by Dr. Guillen, are not only chronicles of science, but also gripping dramas of jealousy, fame, war, and discovery. Dr. Michael Guillen is Instructor of Physics and Mathematics in the Core Curriculum Program at Harvard University.

    Includes a poster of Theodore Gray's iconic photographic periodic table of the elements! Based on seven years of research and photography by Theodore Gray and Nick Mann, The Elements presents the most complete and visually arresting representation available to the naked eye of every atom in the universe. Organized sequentially by atomic number, every element is represented by a big beautiful photograph that most closely represents it in its purest form. Several additional photographs show each element in slightly altered forms or as used in various practical ways. Also included are fascinating stories of the elements, as well as data on the properties of each, including atomic number, atomic symbol, atomic weight, density, atomic radius, as well as scales for electron filling order, state of matter, and an atomic emission spectrum. This of solid science and stunning artistic photographs is the perfect gift book for every sentient creature in the universe.

    We often overlook the historical link between mathematics and technological advances, says Stewart—but this connection is integral to any complete understanding of human history.Equations are modeled on the patterns we find in the world around us, says Stewart, and it is through equations that we are able to make sense of, and in turn influence, our world. Stewart locates the origins of each equation he presents—from Pythagoras's Theorem to Newton's Law of Gravity to Einstein's Theory of Relativity—within a particular historical moment, elucidating the development of mathematical and philosophical thought necessary for each equation's discovery. None of these equations emerged in a vacuum, Stewart shows; each drew, in some way, on past equations and the thinking of the day. In turn, all of these equations paved the way for major developments in mathematics, science, philosophy, and technology. Without logarithms (invented in the early 17th century by John Napier and improved by Henry Briggs), scientists would not have been able to calculate the movement of the planets, and mathematicians would not have been able to develop fractal geometry. The Wave Equation is one of the most important equations in physics, and is crucial for engineers studying the vibrations in vehicles and the response of buildings to earthquakes. And the equation at the heart of Information Theory, devised by Claude Shannon, is the basis of digital communication today.An approachable and informative guide to the equations upon which nearly every aspect of scientific and mathematical understanding depends, In Pursuit of the Unknown is also a reminder that equations have profoundly influenced our thinking and continue to make possible many of the advances that we take for granted.

    And yet for many years it was equally baffling for scientists themselves. Manjit Kumar gives a dramatic and superbly-written history of this fundamental scientific revolution, and the divisive debate at its heart.For 60 years most physicists believed that quantum theory denied the very existence of reality itself. Yet Kumar shows how the golden age of physics ignited the greatest intellectual debate of the twentieth century.Quantum sets the science in the context of the great upheavals of the modern age. In 1925 the quantum pioneers nearly all hailed from upper-middle-class academic families; most were German; and their average age was 24. But it was their irrational, romantic spirit, formed in reaction to the mechanised slaughter of the First World War that inspired their will to test science to its limits.The essential read for anyone fascinated by this complex and thrilling story and by the band of young men at its heart.

    However, according to Hofstadter, the formal system that underlies all mental activity transcends the system that supports it. If life can grow out of the formal chemical substrate of the cell, if consciousness can emerge out of a formal system of firing neurons, then so too will computers attain human intelligence. Gödel, Escher, Bach is a wonderful exploration of fascinating ideas at the heart of cognitive science: meaning, reduction, recursion, and much more.

    It has been inspired by the scientific ferment that swept through Britain at the end of the 18th century, and which Holmes now radically redefines as 'the revolution of Romantic Science'.

    By the soldier, writer and founder of the world Scouting movement. Recounts Baden-Powell's experiences in espionage during his military career, and talks about 'the sport of spying'. Details some of his adventures scouting out military emplacements in foreign countries, establishing a cover and collecting information. Also details the different types of spies. Baden-Powell shows that spying is a craft that can be learned, but also requires a certain intelligence and ability to swiftly improvise and adapt to situations in the field. The book acts as a great introduction to the field-craft of being a spy. Illustrated with the author's own sketches.
