Prime Obsession: Bernhard Riemann and the Greatest Unsolved Problem in Mathematics, by John Derbyshire
Very engaging account of the history of the Riemann Hypothesis, which is central to prime numbers especially but if proven is known to imply a great number of other results. Got into enough actual mathematics to be a great read for me.
The Equation That Couldn't Be Solved: How Mathematical Genius Discovered the Language of Symmetry, by Mario Livio
Recounts a lot of the history of the development of group theory and its application to proving that general quintic equations do not have algebraic solutions. Much lighter on the math and heavier on the human interest which was okay with me as there are some pretty colorful characters involved.
Fermat's Enigma: The Epic Quest to Solve the World's Greatest Mathematical Problem, by Simon Singh
Covers the history surrounding Fermat's Last Theorem. I read it quite a while ago so I'm hazy on the details but it was written after the theorem was proven and I think devotes two chapters to the story of the proof. This is the story of the proof, not an explanation as such a thing would be way beyond the realm of popular literature.
This is then foiled when pirates spend $10-20 on a pair of tinted glasses that filter out red light.
Except that it's a green laser. If they can find a pair of sunglasses that filters out the right frequency of green light without filtering out the rest of the light they'll still need to see and operate, then that could be a countermeasure. At the least it would force them to change their mode of operations somewhat.
For what it's worth, the review appears to be a verbatim copy of the first review on amazon.com, by one "Gary Sorkin, Pacific Book Review".
Pacific Book Review, in its profile on amazon.com, describes itself as follows: "We review books for well known authors and emerging authors, and enabling many first time authors to reach the publishers with a recognizable review. We help you get the exposure you need to market your book effectively. We review both published and unpublished books. The only wish we have is for your success as an author."
It appears that they are a buzz generator.
My wife and I have had success with making our own flashcards, each with a different character or compound word.
Or, maybe the poll designers were just bad at math.
