Berlin in the present day

When reconnaissance pilots brought back precious surveillance photos during World War II (WWII) they could not have imagined that they would one day be comparable with the cityscape seen from satellite 50 years into the future, and available around the world at the touch of a button. Google has made this possible with new functionality for Google Earth - historical WWII imagery - giving people a unique opportunity to see the effect of past events using today's mapping technology.  Read More

NIST postdoctoral researcher James Chin-wen Chou with the world's most precise clock that ...

Physicists at the National Institute of Standards and Technology (NIST) have built an enhanced version of an experimental atomic clock based on a single aluminum atom that would neither gain nor lose one second in about 3.7 billion years. That makes it the world’s most precise clock, more than twice as precise as the previous pacesetter based on a mercury atom.  Read More

Roman numerals surround the docked device, the screen of which displays analog clock hands...

Everywhere you look these days, someone is putting an iPod dock into something to try and convince you to play your favorite audio device through their product. SI Products has launched a few interesting variations on the dock theme at this year's CES trade show in Las Vegas including a voice-controlled alarm clock, a "Roman Clock" and a news and weather information center.  Read More

The Bulbdial Clock - an electronic take on an ancient timepiece.

The Bulbdial Clock is an electronic take on our oldest way of telling time - the sundial. Instead of relying on shadows cast by the sun, this timepiece features three layers of colored LEDs that rotate around the clock face, casting shadows to represent the hour, minutes and seconds.  Read More

Talking alarm clock shows kids when it's OK to get out of bed

We’ve seen alarm clocks that make you work, think and even run in the wee hours, but here's one that actually aims to ease early morning frustration. Teach Me Time! is a talking alarm clock that's not only designed to teach children to tell the time - it can also be programmed to give them a "green light" when it's OK to get out of bed – giving parents some much needed shut-eye.  Read More

Michael Bennet-Levy discusses the Steuart’s Patent vacuum tank regulator

The second in our series of interviews with Michael Bennet-Levy looks at the Steuart’s Patent vacuum tank regulator – a clock produced in 1923 that its makers, J & D Meek, claimed was accurate to “better than a second a year.” If true this would have made it the most accurate timekeeper in the world prior to the invention of Caesium clocks in the mid 1950s. The essence of the Steuart regulator is that the electric motor drives the clock and the pendulum governs and corrects the speed of the motor. Neither is connected. Ideal for telescopes (because it doesn't tick), the clock was used as a stand-in for Big Ben during WWII and in the opinion of the Scientific American it marked “the most important development in clock-making which has taken place in modern times.”  Read More

The iPX3 Instant Messaging Clock 
 (Pic: Innovatoys)

When communicating via the typed word, sometimes a text or regular instant message just won’t do the trick. Here to take personal communication to a quirky new level is the iXP3 Instant Messaging Clock, which, through a simple Internet connection, changes from a mild-mannered clock to a personal messaging device that projects messages in the air.  Read More

The Sony ICF-CL75iP - great looks and functionality

Alarm clocks (uncool), digital photo frames (ho-hum), and iPod/iPhone docks (seen ‘em all). Three pretty bland objects, right? But give them to Sony and what you get back is one smooth-looking piece of equipment. The Sony ICF-CL75iP has beautifully melded three boring CE products to deliver an item that would easily grace any horizontal surface at home or at the office.  Read More

The Qlocktwo offers stunning good looks and a thoroughly pleasant time-keeping experience ...

What's so great about numbers anyway? And why is it that the circular form seems so sought after? After all, the Qlocktwo from proves beyond reasonable doubt that it's cool to be square and words are what matter most. The familiar rounded clock face is abandoned in favor of a stylish and elegant, cornered design where illuminated letters spell out the time at set intervals. It's time-signal receiver ensures this quartz-driven timepiece is always accurate and its interchangeable faces offer numerous color coordination options.  Read More

About 1 million ytterbium atoms illuminated by a blue laser in an experimental atomic cloc...

Technically, no clock can be more accurate than cesium standards such as NIST-F1 – the cesium fountain atomic clock that serves as the United States' primary time and frequency standard. But researchers have managed to develop an experimental atomic clock based on ytterbium atoms that boasts precision comparable to that of NIST-F1. The humble second was chosen as the International System of Units' (SI) base unit of time since it is based on the properties of the cesium atom (one second is the duration of 9,192,631,770 cycles of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom).  Read More
