World First: Physicists Use Laser ‘Tweezers’ to Grab, Merge Individual Atoms
While we vaguely understand how atoms unite to form molecules, we’ve never been able to directly witness exactly how this happens… until now.
The breakthrough could pave the way for humans to build at the atomic level.
Physicists from the University of Otago recently managed to ‘grab’ two isolated atoms with a pair of laser ‘tweezers,’ hold them still and then push them together.
Previously, scientists could only calculate and theorize how these atomic hook-ups took place, based on observations of groups of atoms cooled down to an extreme degree, but crowd observations didn’t yield
