It has been a week of large numbers: a particle that weighs a trillion trillionth (that's one over ten to the twenty-fourth) of a grain of sand; a computer that analyses a billion chess positions a second. It is very difficult to have even a grasp of what such huge numbers mean. Once you get past a million or so, another couple of zeroes seems, to most of us, neither here nor there. So here's a quick guide to a billion:

A billion is 1,000,000,000.

There are a billion seconds in 32 years.

There are a billion people in India.

There are a billion letters of the alphabet in the average small bookshop.

There are a billion musical notes in 20 copies of the complete works of Mozart.

Competition:

How good are you at estimating large numbers? Try these:

A: The number of minutes Mozart lived.

B: The number of different possible lottery tickets.

C: The population of France.

D: Spots drawn by Disney's animators for 101 Dalmations.

E: Cars made in Japan in 1991.

F: Bottles of champagne drunk in the UK last year.
