Scientists have found a way to see ultrafast molecular interactions inside liquids using an extreme laser technique once ...

The motion of a ball placed in a bowl is an example of simple harmonic motion. When the ball is placed at the centre of the bowl, the net force acting on the ball is zero and thus there is no motion.

The internal model principle is a 30-years-young idea that serves as the basis for a myriad of modern motion control approaches. One such algorithm — harmonic cancellation — is indispensable to ...
