Like many of us, there are some elements of mathematics that Ms. Vos Savant doesn't understand. Unfortunately, instead of investigating these subjects or asking questions of experts, the author concludes that there must be something wrong with the mathematics. Although this book purports to be about Wiles's proof of Fermat's Last Theorem, it is really a description of all the things that are "wrong" in mathematics, including some comments on Wiles's work. This can make for some entertaining reading, like her argument against the imaginary number i, but it can also be quite annoying, like her incredibly disrespectful comment (under the heading "a possible fatal flaw [in Wiles's proof]") that Wiles ought to check and make sure that his "proof" doesn't also rule out solutions to the equation with exponent 2, since we know that there are solutions in this case. A big plus for this book is the evidence it provides for the relative unimportance of I.Q.
