Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether in a physics class, in the lab, or in popular science writing, is left thinking something like, "Now, that is really weird." For some, this translates to weird and wonderful. For others it is more like weird and disturbing. /news/2025-07-electron-magnetic-moment-state-values.html Quantum Â鶹ÒùÔºics Wed, 09 Jul 2025 09:20:39 EDT news671271633 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 around a point.
