Surprising as it may sound, 107 years after the introduction of general relativity, the meanings of basic concepts are still being worked out. More than a century after Albert Einstein unveiled ...

In this video, we explain the conservation of angular momentum in AP Physics 1, showing why angular momentum remains constant and how it applies to rotating systems. You’ll see clear examples that ...

A new publication from Opto-Electronic Advances, 10.29026/oes.2024.240001 discusses robust detection technology of orbital angular momentum of partially coherent vortex light fields in complex ...

An international research team have observed “orbital pumping,” a new phenomenon in which orbital currents are generated from the precession of magnetization in magnetic materials. Microwave-induced ...

The first laboratory realization of the longstanding but never-before confirmed theory of the puzzling formation of planets, stars and supermassive black holes by swirling surrounding matter has been ...

The inner solar system spins much more slowly than the laws of modern physics predict, and a new study may help to explain why. A thin disk of gas and dust — known as an accretion disk — spirals ...
