When you sit at your desk in the office or at home, you probably have several things sitting on your desktop surface that, to our eyes, appear to be standing still. However, researchers at MIT say if ...

Objects that obey the rules of quantum mechanics behave very differently from those in the familiar world around us. That difference leads to an obvious question: is it possible to get an everyday ...

Redefinition of the kilogram will not make the kilogram more precise, but it will make it more stable. A physical object can lose or gain atoms over time, or be destroyed, but constants remain the ...

Quantum mechanics usually applies to very small objects: atoms, electrons and the like. But physicists have now brought the equivalent of a 10-kilogram object to the edge of the quantum realm.

The LIGO gravitational wave observatory in the United States is so sensitive to vibrations it can detect the tiny ripples in space-time called gravitational waves. These waves are caused by colliding ...

Scientists are hoping to redefine the kilogram by counting the number of atoms in the roundest objects ever made. The kilogram is the only base, or SI, unit still defined by a physical object, a bar ...
