Twilight Zone, 'Time Enough At Last'

German boffins' clock drops 10 seconds in a billion-and-a-half years

Optical clocks are already so accurate that you can expect them to be out by a second every 15 billion years, but they suffer from frequent downtime. Now a group of boffins from The National Metrology Institute of Germany (PTB, which stands for Physikalisch-Technische Bundesanstalt) reckon they've got that problem licked, by …

Got a big day planned in 15 billion years? You need this clock

The world's most accurate clock has been invented, and is ideal for anyone who doesn't want to be a second late over billions and billions of years. Boffins have improved the accuracy of the best optical atomic clock by a factor of three, so that it will not lose a second in 15 billion years – which is greater than the age of …

At the third beep, the Atomic Clock will be 60 ... imprecisely

Feature The atomic clock celebrates its 60th birthday this year. John Watkinson looks at the story of this enabling technology that lies behind GPS and DAB and discusses its roots in quantum mechanics and relativity. Readers are warned that they might need to lie down for a while after reading this article. The story probably begins …

Time is on their side: NIST's new atomic clock accurate for 300 MEEELLION years

Vid Some people are nuts about knowing the correct time, but the boffins at the US National Institute of Standards and Technology (NIST) have taken such habits further than anyone else with a new atomic clock that's accurate to 10 trillionths of a second per day. The clock, snappily dubbed NIST-F2, uses the frequency of a …

The Cesium 133 atomic wristwatch

Atomic clocks come to your wrist

Smartwatches? Who'd bother now that personal atomic clocks are on the agenda? The timepiece in question is called the Cesium 133 and has been announced by high-end Hawaiian watch outfit Bathys Hawaii. The watch is said to contain “a single chip” wherein resides “a laser, a heater, a sealed cavity of cesium gas, a microwave …

Brit horologist hammers out ‘first’ ATOMIC-POWERED watch

Pic Could this be the chronometrist’s ultimate timepiece, the peak of horological haute couture? British bespoke movement maker Hoptroff today claimed to have produced the world’s first personal chronometer with an on board atomic clock. The result, says Hoptroff, is a accuracy of 1.5 seconds every 3.15 x 1010 seconds - that’s …

Nuke clock incapable of losing time chimes with boffins

The force that binds neutrons to an atom's nucleus could be used to create clocks that are 100 times more accurate than today's best atomic clocks, say physicists at the University of New South Wales (UNSW). The nuclear clock outlined in a paper accepted for publication in Physics Letters Review would neither lose nor gain 1/ …

Boffins quarrel over ridding world of leap seconds

The measurement and regulation of time could start to change this week if an ITU meeting in Geneva, Switzerland, gives the nod. International Telecommunication Union members are discussing whether Co-ordinated Universal Time (UTC) should be set using a system that does not factor in the Earth's imperfect spin – which …

Atomic time boffins build better second-watcher

US researchers recently named the atomic clock at the UK's National Physical Laboratory (NPL) in London the most accurate atomic timepiece on the planet. Experts from the University of Pennsylvania found that NPL-CSF2 loses just one nanosecond every two months. It's a badge of honour for NPL, the birthplace of the first …

Amazing 'pulse of darkness' ray tech birthed in US gov labs

US government boffins say they have invented a fiendishly cunning new kind of laser running on quantum dots which, rather than producing pulses of light, actually emits pulses of intense darkness. Unsurprisingly but mildly sinisterly, the new invention has been dubbed the "dark pulse laser". It works using extremely clever …

Quantum superclock will be accurate past end of life on Earth

US government boffins say they have built a clock so precise that it will still be accurate to within one second when life on Earth has ceased. The "quantum logic clock" will neither gain nor lose a second over the next 3.7 billion years, according to its makers at the US National Institute of Standards and Technology (NIST). …

DARPA wants microscopic atom clocks on chips

Pentagon boffinry chiefs have announced that they'd like a very small, super-accurate atomic clock, so small that one day you might build it on a chip. Apparently, they would like to mount these nano superclocks inside the heads of their planned spy legion of brainchipped cyborg zombie insects. The Chip-Scale Atomic Clock ( …
