Gun Stops Bullets in Mid-Air

Gun Stops Bullets in Mid-Air

Researchers at the University of Texas at Austin have built a “coilgun” that works in reverse, stopping atom-sized and molecule-sized ‘bullets’ in mid-flight. Coilguns have been a standard feature in science fiction books and movies, and decades of military research ...

ATLAS Detector Finally Assembled

ATLAS Detector Finally Assembled

The final piece of the ATLAS particle detector, located in Geneva, Switzerland, has finally been lowered into the underground CERN laboratory collision hall. This marks an important milestone in the construction of the Large Hadron Collider (LHC), which will eventually ...

What is Adiabatic Computation?

The adiabatic computation stresses the deep and mysterious connection between physics and mathematics. Using a principle of quantum mechanics we try to find a shortcut to solutions of mathematical problems. It is not clear why we can use physics to ...

Bending Light the Wrong Way

Bending Light the Wrong Way

A Princeton University research team has recently created an easy-to-produce material that has the rare ability to bend light in the opposite direction from all naturally occurring materials. This new substance belongs to the relatively new class of materials called ...

Heavy Metals

Heavy Metals

A team of physicists recently found that an atomic nucleus can hold many more neutrons than what was previously considered possible. In experiments conducted earlier this year, researchers created and detected one new ultra-heavy isotope of magnesium – magnesium-40 – ...

What is a quantum computer?

What is a quantum computer?

In quantum computation we use quantum physics to compute. The use of physics in computation raises some deep philosophical problems concerning the relation of math to physics. It concerns the definition of the term ‘computer’ as a physical object. We ...

Time Machine Getting Closer to Reality?

Time Machine Getting Closer to Reality?

Possibly the first practical model of a time machine proposed by Professor Amos Ori from the Technion Israel Institute of Technology, may prove to be the first step towards a construction of a mechanism that will allow time travel into ...

Wireless Power Demonstrated

Wireless Power Demonstrated

Researchers from MIT were able to light a 60watt light bulb wirelessly from a distance of about 2 meters. If the MIT scientists have their way, in a few-year’s time we will all be charging our cellular phones, MP3 players ...
