But what did Wittgenstein really say?

    At the subatomic level, one particle seems to know what the others are doing, and according to Heisenberg's "uncertainty principle", there is a limit on how accurately nature can be observed. And yet the theory is amazingly accurate and widely applied, explaining all of chemistry and most of physics. "Introducing Quantum Theory" takes us on a step-by-step tour with the key figures, including Planck, Einstein, Bohr, Heisenberg and Schrodinger. Each contributed at least one crucial concept to the theory. The puzzle of the wave-particle duality is here, along with descriptions of the two questions raised against Bohr's "Copenhagen Interpretation" - the famous "dead and alive cat" and the EPR paradox. Both remain unresolved.

    Various competing schools of sociology have attempted to fit observations of social phenomena into different conceptual systems. Introducing Sociology traces the origins of these systems from Enlightenment thought and the pioneering work of Auguste Comte to subsequent developments in Karl Marx, Herbert Spencer, Emile Durkheim and Max Weber. The rapid expansion of sociology in 20th-century America and Britain, the post-World War II dominance of Talcott Parsons, the Chicago School and the rise of Structuralism are brilliantly outlined in a clear, graphic form. The book also examines the array of concepts and methods of research that have been applied to the study of society by the key analysts. This book is essential reading for students of the subject and for anyone interested in understanding the functioning of society.

    But can machines really think? Is the mind just a complicated computer program? Introducing Artificial Intelligence focuses on the issues behind one of science's most difficult problems.

    Now genetics is exploding, and before long we will have the complete code, written in three thousand million letters of DNA, of what makes a human being.

    Born in Vienna in 1882, Melanie Klein became a pioneer in child psychoanalysis and developed several ground-breaking concepts about the nature and crucial importance of the early stages of infantile development. Although she was a devoted Freudian, many of her ideas were seen within the psychoanalytic movement as highly controversial, and this led to heated conflicts, particularly with Freud's daughter, Anna. Introducing Melanie Klein brilliantly explains Klein's ideas, and shows the importance of her startling discoveries which raised such opposition at the time and are only now being recognized for their explanatory power. Her concepts of the depressive position and the paranoid-schizoid position are now in common usage and her work has to be taken seriously by psychoanalysts the world over. She is also now important in many academic fields within the human sciences.

    His style and assaults on sociology, feminism and Marxism have exposed him to accusations of being the pimp of postmodernism.

    It's about the broken, wrinkled, wiggly world - the uneven shapes of nature, unlike the idealized forms of Euclidean geometry. We see fractals everywhere; indeed we are fractal! Fractal Geometry is an extension of classical geometry. Using computers, it can make precise models of physical structures - from ferns to galaxies. Fractal geometry is a new language. Once you speak it, you can describe the shape of cloud as precisely as an architect can describe a house.

    This text on Lacan is one of a number of titles that is being relaunched with an updated cover.

    What really happens at the most fundamental levels of nature?Introducing Particle Physics explores the very frontiers of our knowledge, even showing how particle physicists are now using theory and experiment to probe our very concept of what is real.From the earliest history of the atomic theory through to supersymmetry, micro-black holes, dark matter, the Higgs boson, and the possibly mythical graviton, practising physicist and CERN contributor Tom Whyntie gives us a mind-expanding tour of cutting-edge science.Featuring brilliant illustrations from Oliver Pugh, Introducing Particle Physics is a unique tour through the most astonishing and challenging science being undertaken today.

    This work traces his understanding of the cognitive realities involved in the use of language and the technical apparatus needed to represent it.

    This updated edition of Introducing Jung brilliantly explains the theories that underpin Jung’s work, delves into the controversies that led him to break away from Freud and describes his near psychotic breakdown, from which he emerged with radical new insights into the nature of the unconscious mind – and which were published for the first time in 2009 in The Red Book. Step by step, Maggie Hyde demonstrates how it was entirely logical for him to explore the psychology of religion, alchemy, astrology, the I Ching and other phenomena rejected by science in his investigation of his patients’ dreams, fantasies and psychic disturbances.

    Superbly illustrated by Borin Van Loon, the book illuminates this process through a rich legacy of stories and explains the practices of meditation, Taoism and Zen. It goes on to describe the role of Buddhism in modern Asia and its growing influence on Western thought.

    He's put it all in: the origins of Marxist philosophy, history, economics; of capital, labor, the class struggle, socialism. And there's a biography of "Charlie" Marx besides.Like the companion volumes in the series, Marx for Beginners is accurate, understandable, and very, very funny.

    His plays pack theatres and provide Hollywood with block-buster scripts; his works inspire mountains of scholarship and criticism every year. He has given us many of the very words we speak, and even some of the thoughts we think. Nick Groom and Piero explore how Shakespeare became so famous and influential, and why he is still widely considered the greatest writer ever. They investigate how the Bard has been worshiped at different times and in different places, used and abused to cultural and political ends, and the roots of intense controversies which have surrounded his work. Much more than a biography or a guide to his plays and sonnets, Introducing Shakespeare is a tour through the world of Will and concludes that even after centuries, Shakespeare remains the battlefield on which our very comprehension of humanity is being fought out.
