Then quickly passing Piet Hein&#8217;s board game Hex.<\/p>\n<p>Why we&#8217;re introduced to Tarzan and Jane in the midst of an otherwise interesting subject, &#8220;Walking with quadropeds&#8221; &#8211; the patterns of the gaits of four legged animals, I have no idea.<\/p>\n<p>Chapters 7, 8, and 9 touches upon time travel, which &#8211; as I recall it &#8211; is much more physics and sci-fi than mathematics. Luckily though chapter 10 serves a nice gem &#8211; Cone with a Twist &#8211; the sphericon.<\/p>\n<p>Chapter 11 touches upon the shape of a drop, and in chapter 12 we&#8217;re back to probability and fallacies in The Interrogator&#8217;s Fallacy, where we now use Bayes&#8217; theorem and Mathews&#8217;s formula. There&#8217;s an error in the formula printed on page 173 at the top though, it should be:<br \/>\nP(A|C) = P(C|A) * P (A)\/ P(C)<\/p>\n<p>Then we get to the title chapter: Cows in the Maze.
