Quantum Explained | Quantum & Astrophysics on Instagram: "This experiment demonstrates the conservation of angular momentum, one of the most fundamental laws in physics. In a closed system, when no external torque acts, the total angular momentum remains constant. By changing the shape or distribution of mass, we can see changes in rotational speed — but the overall angular momentum stays the same. This principle explains how figure skaters spin faster when they pull their arms in, or how planet

Particles are not fundamental elements of reality 🤯⚛️
