Have you ever noticed when moving furniture that heavy objects are easier to move if you rotate them at the same time as you push? Many people intuitively do this right. An international research team ...

Researchers studied the physics of a finger snap and determined how friction plays a critical role. Using an intermediate amount of friction, not too high and not too low, a snap of the finger ...
