🌀 Coriolis on a Turntable: Rotating vs Inertial Frame and the Inertial Circle Lab

Slide a frictionless puck across a spinning turntable and watch it curve on the disc while it travels straight in the room. Compare the rotating and inertial frames, the paraboloid-dish inertial circle of radius u/2 omega, a deflection-against-spin experiment, and a real-Earth Coriolis calculator by latitude.
