Imagine you want to study what happens when an object accelerates. Oh, this is way before any of that internet stuff—also, no computers or electronics. In fact, let's say it's the year 1780. What do ...

According to Theodor Hänsch, director at the Max Planck Institute for Quantum Optics (MPQ) in Germany and one of the winners of the 2005 Nobel Prize in Physics, a laser frequency comb can now be used ...

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.

Matter has the mind-boggling ability to behave like waves as well as particles but it has taken physicists some time to exploit this effect. In recent years, however, various groups around the world ...

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 ...

Based on a silicon MEMS (micro-electro-mechanical system) variable-capacitance sensing element, the Type 8315A high-sensitivity, low-noise, single-axis accelerometers from Kistler North America ...

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 ...

You're going at the speed limit down a two-lane road when a car barrels out of a driveway on your right. You slam on the brakes, and within a fraction of a second of the impact an airbag inflates, ...
