A huge breakthrough decades in the making was made just a few months ago, and already scientists are realizing its potential: A measurement of the gap between the quantum energy states of a thorium ...

Nuclear clocks would measure time based on changes inside an atom's nucleus, which would make them less sensitive to external disturbances and potentially more accurate than atomic clocks. These ...

Nuclear effect The deformed shape of the ytterbium-173 nucleus (right) makes it possible to excite the clock transition with a relatively low-power laser. The same transition is forbidden (left) if ...

Chinese scientists have engineered a clock so accurate it could lead to a redefinition of the second and an ultraprecise global time standard. The new optical clock is so accurate that it loses or ...

Just about every electronic device has some silicon semiconductors inside these days—from transistors to diodes to integrated circuits. [Charles] is trying to build a “No-Silicon digital clock” that ...

[Kelton] from Build Some Stuff decided to create a clock that not only had kinetic elements, but a healthy dose of Rube Goldberg inspiration. The result is a work in progress, but one that looks ...

The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate. In 2003, engineers from Germany and ...

(TNS) — In 2003, engineers from Germany and Switzerland began building a bridge across the Rhine River simultaneously from both sides. Months into construction, they found that the two sides did not ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. NASA plans to establish a Coordinated Lunar Time (LTC) in order to support future moon and space exploration, the agency ...

WASHINGTON — NASA wants to come up with an out-of-this-world way to keep track of time, putting the moon on its own souped-up clock. It's not quite a time zone like those on Earth, but an entire frame ...

A powerful laser shines into a jet of gas, creating a bright plasma and generating ultraviolet light. The light leaves a visible white line as it interacts with leftover gas in the vacuum chamber.
