Fleeting Nobel Prize in Physics/Introduction by Professor Chen Song-Xian from the Department of Applied Physics and Chemistry

How fast can time fly? If you think a few milliseconds will be enough to measure changes as quick as the blink of an eye, then what science has achieved today will definitely leave you mind-blowing. Imagine that you get up in a sunny morning with a very good mood, and you really want to have a camera to capture the good moment. This camera, if how sunlight slips through your fingers can even be photoed, will need to take 10^8 snapshots per second. How about sunlight slips through atoms in solids? Well, sounds crazy, but 10^18 snapshots per second is the answer. This super camera will need shutters of resolutions in attoseconds or 10^-18 seconds.


The Nobel Prize in Physics 2023 was awarded jointly to Pierre Agostini, Ferenc Krausz and Anne L’Huillier "for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter"

This method or technology allows scientists to capture electron dynamics and motions from one atom to another, and it is still a progressing technology! With this "super camera", electrons can be examined in more detail, advancing our understanding of fundamental physics.
