@mcc (the question was “why does a golf ball roll into the hole and then pop out again?”)

@mcc I don’t even need quantum effects for this. I was in a classical mechanics colloquium given in the math department once and got there when the speaker showed that the answer just pops out magically if you take the reference frame to be the point of contact of a sphere rolling inside a cylinder and analyze the system based on the Coriolis torque.
