内容简介

Two decades in the making, 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 nonscientists alike to participate in what promises to be a major intellectual revolution.

    在图书馆找到了这本书,一千多页。但不难发现其核心思想(在书中反复被强调):宇宙的一切过程都遵循非常简单的运算,而且这个运算很可能就是某种元胞自动机。总之,一切的奥秘也许就起源于类似的简单规则。作者使用了很强的语气,例如“我强烈认为”,“我强烈怀疑”。可惜除了一些令人印象深刻的例子外,并没有给出强有力的证据。因为专业原因,主要关注元胞自动机在流体力学中应用,而书中对这一部分只是给出非常简单的定性的例子,并未讨论如何(为什么无法)给出定量的精确描述。然而,一些大胆的观念和对传统科学方法(尤其数学)批判的态度还是很有启发性01-25

    不懂 真的没懂 turing machine那部分简直天书12-21

    最开始介绍了诸如Celluar automata,mobile automata, Turing machine, register machine等自动化系统,通过大量举例想说明几个重要点:简单可以产生复杂,离散下的现象在连续情况下依旧存在。后面还重新定义了随机,甚至Mathematica中的Random方法就是通过Rule30产生。剩下的部分就是用Cellular automata去类比数学系统、物理系统中的现象,以此来说明它们之间等价的可能性。最后讨论了介绍的自动系统之间的等价性,以及计算的等价性。前面还好,还能跟上,从中间开始就崩溃了,太笨了。Wolfram通过大量实验来介绍他所谓的New Kind of Science,貌似不太入很多人的法眼啊。12-31
