This book brings together all the work in a new field of physics, the chaos theory, an extension of classical mechanics. The author shows how computers have been able to help researchers, by mapping the whole plane of solutions of non-linear equations.

'What is a self, and how can a self come out of inaminate matter?' This book examines this riddle. Linking together the music of J S Bach, the graphic art of Escher and the mathematical theorems of Godel, as well as ideas drawn from logic, biology, psychology, physics and linguistics, it reveals the mysteries of human thought processes.

Winner of the Nobel Prize for Physics in 1965, Richard Feynman was one of the world's greatest theoretical physicists, but he was also a man who fell, often jumped, into adventure. This work presents the taped conversations that Feynman's had with his friend Ralph Leighton over a period of years.

Was there a beginning of time?, Could time run backwards? and Is the universe infinite are just some of the questions considered in this book for the non-scientific layman. The author begins by reviewing the great theories of the cosmos from Newton to Einstein and then delves into the secrets which lie at the heart of space and time.

String theory proclaims that all of the wondrous happenings in the universe are reflections of one grand physical principle and manifestations of one single entity: microscopically tiny vibrating loops of energy. This text relates the scientific story and the human struggle behind this theory.
