Now, physicists at the US National Institute of Standards and Technology (NIST) and the University of Delaware have developed the most accurate and precise atomic clock yet, using a 'web' of light to ...
Time appeared to skip a beat last week when some of the world’s most accurate clocks were affected by a wind-induced power ...
The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...
Considering that 90% of American adults own mobile phones, the practice of interrupting strangers to inquire about the time has almost completely disappeared. Since these devices are so prolific in ...
Picture a clock ticking so steadily that it doesn’t lose a second, even after running for 1 billion years. Scientists are now closer than ever to realizing that level of timekeeping precision, new ...
Craig has worked in automotive media for nearly 20 years, producing content for publications ranging from Autoline and AutoGuide to Roadshow by CNET and EV Pulse. Aside from writing, he’s also ...
NIST traced the problem to its Boulder, Colorado campus, where a prolonged utility power outage disrupted operations. The ...
An extremely cold gas of strontium atoms is trapped in a web of light known as an optical lattice. The atoms are held in an ultrahigh-vacuum environment, which means there is almost no air or other ...
At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...
The field of optical atomic clocks, in combination with ultracold atoms, has transformed precision timekeeping and metrology. By utilising laser-cooled atoms confined in optical lattices, researchers ...
NIST/JILA Fellow Jun Ye works on JILA's strontium clock. Ye has been instrumental in making the clock 50 percent more accurate than it was a year ago. Physicists have measured and controlled seemingly ...
