Excellent vintage film about the first accurate atomic clock

This short film was produced by the film unit of the UK's National Physical Laboratory (NPL) in the 1950s, and explains the principles behind the first accurate atomic clock, which was designed by Louis Essen and built at the National Physical Laboratory in 1955. The NPL's YouTube channel has other videos of interest to science geeks.
