I think a lot of the discord here comes from different understandings of 'gyroscope'.

To me a gyroscope is a symmetrical solid object rotating fast enough to exhibit rigidity in space.

The...

+1

It is about frames of reference. Choose inertial or choose rotating, but not both at the same time.

For me the inertial frame and conservation of angular momentum is simplest in giving an...
