You're sitting in physics class, working on a traditional problem involving forces and acceleration, when you start to wonder where these terms even came from. Were they just dreamed up to bring ...

Researchers have detected the smallest force ever measured -- approximately 42 yoctonewtons -- using a unique optical trapping system that provides ultracold atoms. A yoctonewton is one septillionth ...

Researchers with the Lawrence Berkeley National Laboratory and the University of California Berkeley have measured what is believed to be the smallest force yet recorded – 42 yoctonewtons, or a ...

MANY English mathematicians are in the habit not only of using the word “force” in a certain technical sense—briefly, as cause of change of motion—but of regarding all other senses as loose and ...

I'm at the DAMOP conference right now, listening to talks on the latest and greatest in atomic, molecular, and optical physics. Since I'm here, I thought I'd offer a few little snapshots of cool stuff ...

What is believed to be the smallest force ever measured has been detected by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley. Using ...
