Could clock made from a single atom finally answer the question: What is time?

Could clock made from a single atom finally answer the question: What is time?

Clock made from a single atom could lead to precise measurement of time.

A researcher from the University of California-Berkeley has made a clock from a single atom. Holger Müller, an associate professor of physics at Berkeley, has found a way to tell time by counting the oscillations of a matter wave. A matter wave’s frequency is 10 billion times higher than that of visible light.

“A rock is a clock, so to speak,” Müller said in a statement.
