Brilliant programme about gravity

You've got a few weeks yet to watch Jim Al-Khalili's brilliant BBC4 programme about gravity. I enjoyed the road trip to try to measure the strength of gravity on Snowdon and on the Dartmoor Tors. I was also pleased that a professor refers to mass as the"stuff you are made of". It's not just me then. http://www.bbc.co.uk/iplayer/episode/b08kgv7f/gravity-and-me-the-force-that-shapes-our-lives
