Web “widgets” are small application programs designed to be run inside Web pages. The NIST time widget, created by engineer Andrew Novick, can be used on any Web page. “The widget code tells your browser to go out and grab NIST time content and post it to your page,” Novick explains, “It synchronizes with NIST’s atomic clock in Boulder, Colo., every 10 minutes, thereby guaranteeing its accuracy.”
The widget checks the viewer’s computer to determine which time zone it should display as the default. To add the NIST time widget to your Web page or blog go to www.time.gov/widget/ and copy the code. The code requires Adobe Flash Player to run. A non-Flash version (using HTML5) is under development that will enable the widget to be viewed on additional mobile devices. Also, smaller configurations in multiple shapes, sizes and formats will be available in the months ahead.
NIST’s Boulder Laboratories is the home of the most accurate clock in the world, the NIST F-1 Cesium Fountain clock. It uses transitions in Cesium 133 atoms to measure time to an accuracy of about 1 second in 100 million years.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
