Astronomy Club news

On Thursday 22nd September members of the Kirkintilloch High Astronomy Club participated in a global experiment to measure the meridional (pole to pole) circumference of Earth.  The experiment was first carried out in Greece by Eratosthenes over 2000 years ago. Armed with a metre stick, measuring tape and chalk the group measured the length of shadows cast at local noon. Then demonstrating their skills in mathematics, group members worked together to calculate the circumference of Earth to be 38812 km, 1196 km less than the stated value of 40008 km. However, that’s not so bad considering the requirements were a sunny day and the ability to measure the length of shadows! Further information about the experiment and details about how to participate next year can be found here http://eratosthenes.ea.gr/
