Researchers flip the motion of electrons on ultrafast time scales without slowing them down

To change the direction of motion of a massive object, such as a car, it has to be slowed down and brought to a complete standstill first. Even the tiniest charge carriers in the universe, the electrons, follow this rule. ...
