If you liked the book "Freakonomics: a rogue economist explores the hidden side of everything" (which I loved), there is a good chance you will like this one too. The author may have screwed-up giving it the title he did and by adding "and Other Mathematical Diversions", as it may put off or scare off a lot of people who would find it enjoyable. One would be hard pressed to find a mathematical equation anywhere in the book.
Take for instance the first chapter, "Clock of Ages", on the astronomical clock located in the Strasbourg Cathedral, in the city of Strasbourg, Alsace. Though the current version of the clock dates from 1843, not only was it designed to be Y2K compliant, it is also Y10K functional, designed to directly display the current year up to 9999 and the only revision needed to make it correct for subsequent years would be to paint the number "1" to the left of the display. It will continue to display such events as the correct date for Easter even in the year 19999 (Easter falls on April 3rd in 11842). Though solely a mechanical device, the gears of the clock were designed to be accurate to an error of less than one second per century. There is a gear in the clock that turns only once every 2,500 years and the celestial sphere out in front of the clock will complete one full precessional cycle after the passage of 25,806 years.
After his discussion of the beauty of the design of this clock, the author then takes up a philosophical discussion of time, asking if anyone will still care what date Easter will be in 11842, or even if we will still be counting in years of the Common Era.
The second chapter, "Follow the Money", demonstrates how through even an entirely random process, wealth tends to become concentrated in the hands of a few people, even in a fair system.
The remaining chapters are similarly varied and all are interesting.
A great book with a wide variety of interesting subjects and an engaging, erudite writing style.
