DESCRIPTION:How many colours do we need for a map? In other words\, if we 
 are colouring in the countries on a map\, and we want neighbouring countri
 es to have different colours\, how many colours are enough? Map-makers had
  suspected for a long time that any map could be coloured using just four 
 colours\, but was this right?
