This work abandons the conventional distinctions between history and science. Diamond focuses on what ancient people were endowed with in the way of land, animals and plants, and on the confrontations between less and more advanced people to see how this led to today's inequalities.

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.

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.

Why do memories fade? Why do we lose our tempers? Why do fools fall in love? This work explores the nature and history of the human mind. It looks at the computations and evolutions, and then considers how the mind lets us see, think, feel, interact, and pursue higher callings like art, religion and philosophy.
