Scientists have set up a large experiment to count the number of grains of sand on a beach in Cornwall. To do this they have needed to erect over 130 feet of scaffolding. It has taken five years to set it up.
Seriously, they are counting how many grains are moved up & down by the tide, to provide new fundamental information about the process of coastal erosion.
To see a world in a grain of sand,
And a heaven in a wild flower,
Hold infinity in the palm of your hand,
And eternity in an hour.
William Blake - Auguries of Innocence
