When light loses symmetry, it can hold particles
The outbreak of COVID-19 has changed our lifestyle, and even the environment around us, such as the reduction of carbon dioxide and nitrogen dioxide emissions and the alleviation of water pollution. A more obvious change is that the production of waste related to pandemic prevention has increased significantly. For example, the main component of disposable masks we use every day is plastic fiber....
Three, two, one: astronomers predict SpaceX space junk will hit the Moon
Optical tweezers use light to immobilize microscopic particles as small as a single atom in 3D space. The basic principle behind optical tweezers is the momentum transfer between light and the object being held. Analogous to the water pushing on a dam that blocks the stream, light pushes onto and attracts objects that make the light bend. This so-called optical force can be designed to point to a...
