Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...

In a new study, physicists at the University of Colorado Boulder have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions—a ...

Bringing protons up to speed with strong laser pulses -- this still young concept promises many advantages over conventional accelerators. For instance, it seems possible to build much more compact ...

Addressing the increasing demand to accurately measure acceleration in smaller navigation systems and other devices, researchers have developed an accelerometer a mere millimeter thick that uses laser ...

Accelerometers are essential sensors used in a wide range of applications including shock and vibration testing, car safety systems, and today's hand-held consumer devices. Generally, they sense the ...

Physicists have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions - a feat that many scientists didn't think was possible.
