Edwin Taylor and John A. Wheeler-one of this century's most distinguished physicists - have completely reorganised this popular and well known book to make it accessible to an even wider audience. New topics, imaginative problems, and exceptionally clever illustrations, combined with a compelling narrative and intellectual authority make this a classic text. It is an ideal text for undergraduate .

The author, one of the pioneers of string theory, has produced an accessible guide for the general reader to some of the most formidable modern concepts of mathematics and physics. These include string theory itself, hyperspace, non-Euclidean geometry, Kaluza-Klein theory and supergravity.

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.

Tells the story of one of the greatest scientific discoveries in history. This work looks at the elements 'e', 'm' and 'c'; and honours the scientists whose landmark discoveries paved the way for Einstein. It plots the course of the equation (E=mc2) through the 20th-century, showing how our lives have been revolutionized by its applications.

Unravelling the latest amazing breakthroughs in theoretical physics, Stephen Hawking guides the reader through the evolution of Einsteinian physics to a universe of ten dimensions and a so-called theory of everything.
