How does laser cooling work?

The video explores the concept of laser cooling, a counterintuitive process where lasers are used to slow down atoms and molecules by transferring momentum through photon absorption. This technique allows scientists to achieve temperatures close to absolute zero, enabling the observation of quantum behaviors in macroscale objects. Applications include improving the accuracy of atomic clocks in satellites, which are crucial for GPS functionality. The video also touches on the fun and practical uses of lasers, such as laser hair removal.
