Caesium atomic clock In this clock atoms of vapourised caesium oscillate between two energy levels as they pass back and forth between magnets at each end of the resonator long cylinder lower left Counting these oscillations is the basis of the standard second where one second is about million oscillations The development of the first caesium atomic clock by Louis Essen and Jack Parry in led to the replacement of the astronomical second with the atomic second as the standard unit of time Photographed at the National Physical Laboratory Teddington UK
This giclée print delivers a vivid image with maximum color accuracy and exceptional resolution. The standard for museums and galleries around the world, giclée is a printing process where millions of ink droplets are “sprayed” onto high-quality paper. With the great degree of detail and smooth transitions of color gradients, giclée prints appear much more realistic than other reproduction prints. The high-quality paper (235 gsm) is acid free with a smooth surface.
