My God, how I love this list. I start a thread with an intertaining quote - a sort of computer related pun. It moves to logic states and then on to a fascinating discussion of biology and the "cost of sex"! Well, Wirt's mention of celluar automata reminded me that Stephen Wolfram just published a book he's been working on for twenty years. It's causing quite a stir and I hope to purchase it this weekend. The title is, "A New Kind of Science". As you may recall, Wolfram developed the widely used program(s) called Mathematica. He says of the book, "But for me what has always been most important is the actual process of discovery. For I know of nothing as profoundly exciting as to glimpse for the first time some new and basic truth. And now that I have finished building the intellectual structure that I describe in this book it is my hope that those who read these words can share in the excitement I have had in making the discoveries that were involved." The publisher summarizes the book as follows,"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- -Stephen 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 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. Written with exceptional clarity, and illustrated by nearly a thousand original pictures, this seminal book allows scientists and nonscientists alike to participate in what promises to be a major intellectual revolution."
