From the 12th to the 14th of September this year the 15th Emile Argand Conference on Alpine Geological Studies is being held in Ljubljana and on the final day of the conference I am down to give the keynote address.

Louis de Freycinet elected not to use the method of coincidences when making pendulum observations on hos circumnavigation in the Uranie. There are, however, all sorts of difficulties in discovering what he actually did do.
The experiment described by George Airy in his 1857 paper entitled “Account of pendulum experiments undertaken in the Harton colliery, for the purpose of determining the mean density of the Earth” produced an estimate of the mean density of the Earth that was 20% in error. Why was this?
After his failure to measure the mean density of the Earth in the Dolcoath mine in Cornwall in 1826, George Airy waited 30 years before making another attempt. For this he went to the Harton Pit near South Shields and used innovations such as electrical signalling. But was he any more successful?
