Gold nanorod makes spinning light when struck off-center by an electron beam
Light, as we usually conceive of it, is defined by the astonishing velocity at which it moves from one point to another. For example, in just one second, light can travel most of the distance between Earth and the moon. This property is what makes light useful for communication, which we expect to h...

Light, as we usually conceive of it, is defined by the astonishing velocity at which it moves from one point to another. For example, in just one second, light can travel most of the distance between Earth and the moon. This property is what makes light useful for communication, which we expect to happen at lightning speed in the modern age.
