No.1 Book of Numbers

Why is 7 a lucky number and 13 unlucky? Why does a jury traditionally have `12 good men and true', and why are there 24 hours in the day? This fascinating book explores the world of numbers from pin numbers to book titles, and from the sixfold shape of snowflakes to the way our roads, houses and telephone numbers are designated in fact and fiction.

De ce este 7 un numar norocos si 13 ghinionist? De ce un juri are in mod traditional „12 barbati buni si adevarati” si de ce exista 24 de ore pe zi?
