Chemistry depends on heat. Atoms or molecules bounce around randomly, collide, and form other molecules. At higher temperatures, atoms collide more and the rate at which atoms become molecules ...

For the first time, researchers have observed "quantum superchemistry" in the lab. Long theorized but never before seen, quantum superchemistry is a phenomenon in which atoms or molecules in the same ...

In a Caltech lab, a computer screen showed thousands of tiny points of light—each one a single atom, held in place by laser ...

Time doesn't come from your phone. It doesn't come from your watch either. It comes from atoms oscillating in a vacuum — billions of times a second — inside a system that never stops checking itself.

BOULDER • Every second in a small laboratory room in Boulder, a green light flashes. Within the webs of yellow wire and shelves of computer systems, this green light represents the passage of time.

The most accurate atomic clocks in the world are based on the output of cesium atoms. These ultra-precise fountain clocks measure the frequency and time interval of seconds by using a fountain-like ...

In a telecommunications network, every network element with synchronous intermachine links requires proper synchronization to minimize transport errors. A good example of synchronization is a network ...

Among the elements, cesium, located in the lower left corner of the periodic table, and fluorine, in the upper right corner, are among the largest electropositive and smallest electronegative elements ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. During the question-and-answer period afterwards, somebody asked a ...
