You can be in two places at once

A device that exists in two different states at the same time, and coincidentally proves that Albert Einstein was right when he thought he was wrong, has been named as the scientific breakthrough of the year. The machine, consisting of a sliver of wafer-thin metal, is the first man-made device to be governed by the mysterious quantum forces that operate at the level of atoms and sub-atomic particles.

Normal, everyday objects obey the laws of conventional Newtonian physics, named after Sir Isaac Newton, but these rules break down on the sub-atomic scale and a whole new branch of theoretical physics had to be invented to explain what happens on this sub-microscopic level.

Einstein was the first to embrace quantum physics but later rejected it on the grounds that it made everything unpredictable – "God does not play dice with the universe," he famously stated.
