Stephen Wolfram's book A NEW KIND OF SCIENCE is now available online.
"The online version of the book is intended to supplement the printed book with features that can be achieved only online: visual and textual browsing, navigation through the book's nearly 15,000 index entries, and full-text searching. Each page of the original book has been enhanced with links to related technical notes, downloadable programs, and other elements.
"Wolfram uses his approach to tackle a remarkable array of fundamental problems in science, from the origins of apparent randomness in physical systems, to the development of complexity in biology, the ultimate scope and limitations of mathematics, the possibility of a truly fundamental theory of physics, the interplay between free will and determinism, and the character of intelligence in the universe."
