What are Kaprekar numbers? What is the connection between the Golden Ratio and a sunflower? How many grains of sand would fill the universe? lucky numbers, perfect numbers, the Syracuse algorithm....these and many other questions and facts are covered in this fascinating book. Its the sort of book you pick up to look up a single item and two hours later you are still deep in its pages, moving from one number to another, it is mesmerising.

A nice book for those who like to play with numbers. I have an older version someplace in my library, but I checked this one out from the library. Starting with Number 1, and going up to Graham's number (3???3 etc.), intersting and "curious" ideas about each number are presented. The smallest number about which nothing is discussed is 58. This is a fun read and one can go back and forth looking at Fibonacci and Mersenne numbers, squares and primes, and lots of other stuff.
