Tick, tock US scientists say they have built the world's most precise atomic clocks ... the NIST-F1 caesium fountain clock, for about 400,000 seconds (about five days) to obtain its best performance. But the new ytterbium clocks can …
Atomic clocks are set to become even more precise than they currently are. A new technique can ensure that the "ticking ... In the current study, Ludlow and his colleagues cooled 10,000 ytterbium atoms to 10 Microkelvin, just a hair's …
A pair of atomic clocks based on ytterbium atoms has set a new record for stability. The clocks are like 21 st-century pendulums that could swing back and forth with perfect timing for a period comparable to the age of the universe. The …
According to statistical measurements conducted on the new atomic clock ... The stability of the strontium clock is similar to that of the ytterbium atomic clock unveiled by NIST investigators back in August 2013. All atomic clocks
Scientists claim to have developed a new record-breaking ... The strontium clock's stability - the extent to which each tick matches the duration of every other tick - is about the same as NIST's ytterbium atomic clock. Stability determines in …
US scientists said Thursday they have built the world’s most precise clock, whose ticking rate varies less than two parts in one quintillion, or 10 times better than any other. The clock, made from the element ytterbium ... But the new
Every single GPS satellite is home to a family of atomic ... comes lots of new opportunities for discovery and applications. Here at the University of Western Australia our research group is building an optical lattice clock based …
While we may not need it for punctuality, this new atomic clock will benefit scientific exploration and technological advancements—oh, and put Einstein’s Theory of Relativity to the test. “The ytterbium optical lattice clock has …
Here's a more thorough explanation by the PTB: The new optical ytterbium clock is 100 times more accurate than the previous record PTB "The definition and realisation of the SI unit of time, the second, is currently based on cesium …
The new clock can beat the cesium clock, a type of atomic clock that an international body of experts has used to define the unit of one second. It is about 9.19 billion oscillations. The oscillations per second in the ytterbium clock
