Scientists at the National Institute of Standards and Technology have created what they say is the most accurate clock in the world.
The time achieves this by using the element ytterbium, something that provides stability, which scientists say can have other uses. Unlike using pendulum clocks, clock uses ytterbium atoms approximately 10,000 rare, chilled to a temperature below zero and embedded in optical laser.
Laser optical signal is sent to a precise frequency, moving electrons in cesium atoms. Such is basically a version of tiktaku clock, with a movement of 518 trillion times per second. This causes stability, with the largest number of atoms, being responsible for a steady rate.
