Scientists really don't understand time... but they do have some theories about what it might (and might not) be.

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it encompasses both the intrinsic spin of particles and their orbital motion ...

Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

Three scientists who experimentally probed the blurry realm of the electron have been awarded the 2023 Nobel Prize in physics. Pierre Agostini, Ferenc Krausz and Anne L’Huillier were honored for ...

Physicists have used a machine-learning method to identify surprising new twists on the non-reciprocal forces governing a many-body system. The work is one of the relatively few instances of using AI ...

Nobel laureates demonstrate quantum tunnelling in macroscopic systems, impacting quantum computing and highlighting the importance of basic research.
