Title: Innumeracy: Mathematical Illiteracy and its Consequences
Author: [John Allen Paulos][2], mathematician and well-known skeptic (in the good, modern sense of the word).
Short description: Paulos explains for the general public (and he does it fairly well) why it should understand a little more mathematics and know how to do Fermi calculations and educated probabilistic guesses. The dangers coming from pseudosciences are also highlighted, something very needed nowadays in my opinion.
Math level: +. Some chapters are not that easy to read without a mathematical background, more because of the great number of calculations and logic steps involved in the explanations than because of the math level of those per se.
Price: 9.89$ at [Amazon][3].
