Which is an awesome book. One of the most interesting things I read in it is the infinite sum:

1 + 1/2 + 1/3+ 1/4 + 1/5 + 1/6...

Will eventually surpass ANY number! 10, 100, 1000, 50,000, two hundred thousand million billion etc

Weird but pretty amazing!Tom2011-07-15 14:07:04

If you infinitely add 1 to a number it will reach those numbers too!

Heres another one?

1+2+3+4...rice on a chessboard.

Oh wait that should be double each time lol.Ethan2011-07-15 16:21:15

A more interesting infinite sum of numbers is this:
4/1 - 4/3 + 4/5 - 4/7 + 4/9 - 4/11 + 4/13 ...
The further the series is taken, the closer the sum is equal to pi.

Nice rojo!

Another one is 1/2 + 1/3 + 1/5 + 1/7 + 1/11 ... 1/p where P is prime will diverge to infinity

Prime numbers are amazing, very useful in cryptography as well, apparently it took a while for people to work out it was infinitely random as well.Tom2011-07-15 20:29:14
