The "Weigh the World" challenge is an initiative undertaken by Counting Thoughts in collaboration with the Glasgow Science Centre and
DJB Microtech, with the support of the
John Muir Trust and the
Astronomer Royal for Scotland.
The challenge involved determining the mass of the Earth on June 21st, 2005, at Schiehallion,
in Scotland, using a method inspired by the technique first successfully used there in 1774.
