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 ...

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 ...

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.

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 ...

This force will cause the cart to accelerate—in this case, to the left, or the opposite way it was heading, which is why it slows down during impact and even reverses direction. But what is the ...

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 ...

Scientists have carried out studies both into the advantages of different rider techniques in reducing injury risk to horses, and into the benefits of a method of equine rehabilitation. By using ...

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, ...
