Re: Interesting

"There was a TV programme a couple of years ago where they synchronised two portable atomic clocks, then took one up to the top of Snowdon and back"

i remember that tv show, was Jim Al-Khalili on beeb 4.

lots of different students took time devices to different places, up mountains, further north, south etc, was interesting.

not the beeb but think this might be it.
