Schematic of a single photon with zero angular momentum (green) splitting into two photons (red) with either zero or opposite angular momenta (sketched through the spatially varying color), which adds ...

In this educational film, scientist pilot Owen Garot discusses the principles of conservation laws demonstrated during the Skylab missions in the 1970s. He explains conservation of angular momentum ...

Introduction You might have seen figure skaters spinning around quickly and then tucking their arms to spin faster—or opening them to spin more slowly. This happens, thanks to a physics concept known ...

When a magnetic material like nickel is zapped with an incredibly short laser pulse, it loses its magnetism almost instantly within femtoseconds, or a millionth of a billionth of a second. But physics ...

Optical vortex plays an important role in a variety of fields, such as particle tweezing, quantum communication, astrophysics, and microscopy. Especially, the application of optical vortex has been ...

Photons can have half-integer values of angular momentum when they are confined to fewer than three dimensions. That is the conclusion of physicists in Ireland, who have revived an experiment first ...
