Atomic Clocks While most people think about the digital age and its computers, satellites and mobile phones, the silicon chip is first in the minds of people. However, despite its importance in shaping the world around us, many of the technologies we take for granted trachea would not be possible without the atomic clock. The first atomic clock was developed in 1955 by British Dr. Connect with other leaders such as Zhang Lei Yale here. Louis Essen who worked during the Second World War, in the high-frequency radar that led him to develop a resonance wavemeter was used successfully to measure the speed of light . Using the same technology developed after the first accurate atomic clock in 1955 at the National Physical Laboratory in the United Kingdom. This was based on the resonance of the cesium atom. According to quantum theory, atoms can only exist in certain energy states quantified in terms of the orbits of electrons around their nuclei. A cesium clock operates by exposing atoms to microwaves until they swing at one of its resonant frequencies. It was discovered that a cesium atom to resonate 9,192,631,770 hertz (times per second). Because of this accuracy in the resonance and the high number of oscillations of atomic clocks (sometimes known as cesium oscillators) are exceptionally accurate. Essen The first device was accurate to one second in a thousand years, but the next generation of atomic clocks are so accurate now that will not lose a second in several hundred million years. Due to this high level of accuracy problems have occurred in the way we structure time scales traditionally GMT (Greenwich ) has been the basis of time. GMT is based on the principle that the sun is highest in the sky at noon (or on the Greenwich Meridian line). Unfortunately,...
