The smallest of the world clock consists of one atom of Bashny.Net

Monohydric clock created physicist Holger Mueller of the University of California at Berkeley and colleagues. Scientists interested in the division of time into simple components. The concept is based on hours of amazing de Broglie's hypothesis, which states that particles of matter can behave like waves, that is, will vary according to the pattern. This principle can be used to measure time.

However, one atom will fluctuate too quickly that it can be easily fixed. Therefore, the researchers divided the cesium atom in two halves and one half was forced to move back and forth. Thus, the first half was affected by the movement of the second, and because scientists know exactly how the atom is broken, they can use the data to calculate the original vibrations of the atom, and in fact created the clock.

Of course, this watch, though amazing, but completely impractical. They are not as accurate as a modern nuclear clock, and a billion times smaller. However, an impressive achievement - perhaps in the future there will be quantum clock with negative particles that are there, no. Or watch from antimatter. Of course, wearing these on your wrist, you can not but agree that it is an interesting look at the time.
