Description
(Original Caption) Dr. Harold Lyons(right), Chief of the Microwave Standards section, Bureau of Standards, explains some of the principles of the Atomic Clock to Dr. Edward Condon(left), Director of the Bureau of Standards, and Secretary of Commerce, Charles Sawyer(center), at it's unveiling at the National Bureau of Standards. The clock, more accurate than the stars, employs a brand new standard of frequency of atoms - in this case atoms of the ammonia molecule. It will revolutionize scientific and industrial procedures dependent on precise timing.
