TECH & INNOVATIONAn ultra-precise atomic clock is accurate enough to detect the effects of gravity at a microscopic scale. Check this article to learn more.
New study suggests that laser excitation of thorium-229 nucleus could prove that classical quantum physics and nuclear physics can actually be combined. Find out more about it in this article.
Timekeepers may have to consider subtracting a second from our clocks in 2029 because the Earth is spinning faster. Learn more about it in this article.
Experts have set a project to develop a nuclear clock using scandium with accuracy of up to one second in 300 billion years. Find out more about it in this article.
Atomic clocks would be used in a brand-new dark matter detector experiment to look for evidence of it close to the Sun. Read on to know how scientists would do it.
Researchers have used the accuracy of optical clocks to close in on the mysterious components of dark matter, as well as the coupling between parts - particles and fields - postulated by the standard model of physics.
Researchers have accomplished the high-precision measurement of a thorium isotope's nuclear transition - opening the possibilities for more accurate nuclear clocks.
The Metronome—a 62-foot-wide electronic clock with a 15-digit display facing Manhattan's Union square—has changed its display to the remaining time before the "climate change deadline."
A new laser with a linewidth of just 10 mHz has established a new world record for sharpest laser. Theoretically, a laser (a device which emits light through optical amplification) has a fixed color, frequency or wavelength.
Scientists have set a new record in accurate timekeeping, by creating a new atomic clock that won't lose or gain a second in 15 billion years. This timespan is greater than the estimated age of the Universe itself.
