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 ...
A new experiment confirms that angular momentum conservation holds even when a single photon is split into two.
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 ...
