This long-awaited work from one of the world's most respected scientists presents a series of dramatic discoveries never before made public. Starting from a collection of simple computer experiments—illustrated in the book by striking computer graphics—Wolfram shows how their unexpected results force a whole new way of looking at the operation of our universe. Wolfram uses his approach to tackle a remarkable array of fundamental problems in science: from the origin of the Second Law of thermodynamics, to the development of complexity in biology, the computational limitations of mathematics, the possibility of a truly fundamental theory of physics, and the interplay between free will and determinism. Written with exceptional clarity, and illustrated by more than a thousand original pictures, this seminal book allows scientists and non-scientists alike to participate in what promises to be a major intellectual revolution. About the Author: Stephen Wolfram was born in London and educated at Eton, Oxford and Caltech. He received his PhD in theoretical physics in 1979 at the age of 20, and in the early 1980s made a series of discoveries which launched the field of complex systems research. Starting in 1986 he created Mathematica, the primary software system now used for technical computing worldwide, and the tool which made A New Kind of Science possible. Wolfram is the founder and CEO of Wolfram Research, Inc.—the world's leading technical software company.
