Portable can mean very different things, depending on whom you talk to. (Image: Christian Lisdat) With a new, “portable” atomic clock, scientists are measuring not what time it is but changes to time itself. What do I mean? Researchers …
But those ushering in the new year with gusto ... That’s right, the final minute of 2016 will be 61 seconds long. The reason is because the Earth’s slowing rotation has caused the insanely accurate atomic clocks used by international …
Their work forges new connections between atomic physics and the sudden expansion of the early ... inhospitable area had mismatched quantum properties, …
The NIST has launched a new hyper-accurate atomic clock for the U.S. time standard called NIST-F2. The clock uses a ‘fountain’ of cesium atoms to determine the exact length of a second. The U.S. Department of Commerce’s National …
A team of researchers at the University of Tokyo has developed a new type of optical atomic clock that boasts a 100 quadrillionth of a second accuracy (one quadrillion has 15 zeros). The optical lattice clock is the brain child of …
Scientists have created an atomic clock so precise ... ago researchers at NIST created a clock so sensitive that it could detect the difference in time between two elevations just a foot from each other. But the new clock is even better.
Traders that operate at warp speed are turning to a hyper-accurate "atomic clock" to track their activity and comply with European regulations that will come into force next year. New York Stock Exchange owner Intercontinental Exchange …
The superb precision of an atomic clock is derived from its stability ... We use this laser as a stable optical source in a ytterbium optical lattice clock to resolve an ultranarrow 1 Hz linewidth for the 518 THz clock transition. With the stable …
Let’s count the ways: mind-wandering, lecture-dozing, discovering new cat videos on YouTube — and ... With something called an optical lattice clock, reports BBC News: still an atomic clock, but one that subjects strontium atoms …
For the first time, they took an optical atomic clock out of the lab ... For its first test run, the authors took their new portable clock to the Laboratoire Souterrain de Modane, which is in a lab buried deep in the French Alps. Using an …
