Electron path

Scientists at Brown University (Brown University) managed to shoot on the home video camera movement of a single electron (stable elementary particle, one of the main structural units of matter). The movement of electrons determines many electrical phenomena, such as electrical current in metals and vacuum. ( Wikipedia ) When an electron moves in a liquid medium, it pushes atoms and creates free space around itself (a bubble). Scientists have chosen liquid helium as such medium. Then they attacked the current environment with sound waves - as a result, the electron bubbles expanded to about the size of a speck of dust. This speck of dust and managed to take the camera in night vision mode.
