A new clock is capable of telling the time using nothing more than a single cesium atom.
Scientists developed the device based on several principles including Einstein's Theory of Relativity and the Broglie's matter-wave hypothesis which suggests that matter can behave like waves. To tell the time, it was necessary to measure the regular oscillations in a single particle of matter, a feat that was achieved using time dilation.
"We have demonstrated that you can make a clock from a single massive particle," said researcher Justin Brown. The newly developed clock doesn't keep time as well as more conventional modern atomic clocks but it can nonetheless keep time with a degree of accuracy similar to the first atomic clocks 60 years ago.
"A clock based on just a single atom -- the simplest clock yet -- has now been devised, researchers say."
