The video we have for you demonstrates a quantum stroboscope of an electron done by a group of researchers. It shows cyclically moving objects appear to be slow-moving or even stationary.

The researchers were able to record snapshots of an electron's motions near the particle's natural timescale, which is less than a femtosecond - one billionth of one millionth of a second. Their experiment combined ultrashort light pulses with steady laser light to bring out an electron from an atom in a very controlled way.

With this technique, it could help researchers to delve more into electron-atom interactions in greater details and begin using electrons to observe the poorly-understood state of atoms following ionization.

Enjoy the video below!
