Physicists have used a new optical centrifuge to control the rotation of molecules suspended in liquid helium nano-droplets, bringing them a step closer to demystifying the behavior of exotic, ...

Does orbital motion really follow a simple mathematical law? 🛰️ This video shows how to verify Kepler’s Third Law for circular orbits, connecting orbital period and radius through gravitational ...
