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. (thanks, obadiahlemon)

Hurray, a science documentary that doesn’t talk down to the viewer or try to sex up the subject. Oh, it’s from 60 years ago, I guess that explains it :(

This kind of video reminds me why I became science geek back when I was a kid. Thanks, Xeni. :D
