Fireside Chat ’Above and Below: the Cornish pendulum experiments to weigh the world’

September 10, 2022 @ 5:00 pm - 6:00 pm BST

Presented by Carolyn Kennett.

Going down a Cornish mine with Carolyn Kennett.

In 1826 and 1828 attempts were made by a group of eminent scientists including George Biddlell Airy and William Whewell to measure the density of the Earth. They would travel to the far southwest of England to Cornwall and down the deepest mine in the country at Dolcoath to undertake the experiment. Both attempts were beset by challenges including the unfortunate smashing of one of the precision pendulums. From 2021 to 2022 a group of enthusiasts are going to re-create the experiments within a Cornish mine, led by Carolyn Kennett (FRAS). This fireside chat will explore both the past and modern versions of the experiment as we descend into the bowels of the earth to try and weigh the world.
