BTW, the book that was briefly mentioned in the article, <i>Fractals, Chaos, and Power Laws: Minutes from an Infinite Paradise</i> by Schroeder (<a href="http:&#x2F;&#x2F;www.amazon.com&#x2F;Fractals-Chaos-Power-Laws-Infinite&#x2F;dp&#x2F;0716721368" rel="nofollow">http:&#x2F;&#x2F;www.amazon.com&#x2F;Fractals-Chaos-Power-Laws-Infinite&#x2F;dp&#x2F;...</a>) is truly excellent, it is written in the form of short pieces collected into chapters investigating a very wide-ranging set of phenomena, ranging from Brownian Motion to self-similarity, Cantor sets and cellular automata. For $10-$15 on Amazon, it&#x27;s a great bargain!
