[time-nuts] First "accurate" atomic clock video

[Michael Costolo]

I've always been fascinated with science history.  If you all haven't seen
this already, here is a video from 1955 about the first "accurate" cesium
atomic clock designed by Louis Essen and made in the UK's National Physical
Laboratory.  Interesting that the one made after the prototype was 17 feet
long.
