Electrons moving around in a molecule might not seem like the plot of an interesting movie. But a group of scientists will receive the 2023 Nobel Prize in physics for research that essentially follows the movement of electrons using ultrafast laser pulses, like capturing frames in a video camera.
However, electrons, which partly make up atoms and form the glue that bonds atoms in molecules together, don’t move around on the same time scale people do. They’re much faster. So, the tools that physicists like me use to capture their motion have to be really fast – attosecond-scale fast.
