An Amazing Vintage Video About the World’s First Accurate Atomic Clock

This short video , made at the UK’sNational Physical Laboratory , proudly explain the science behind the world ’s first precise nuclear clock . It was designed by Louis Essen and built at the National Physical Laboratory in 1955 , and the video is worth watching for the voice - over alone .

As the narrator explains : “ The essential parts are not too complicated , and the principle is easily explain . ” He ’s right , of course , but his delivery makes it sound like what follow will require a PhD in physics to sympathise . Do n’t worry , it does n’t ; in fact , the concept behind the clocks that now crop up everywhere fromfancy science labstoinside expensive preampsare really quite straightforward .
