gimbles and precession

Post 1

Sea Change

Does the earth's precession mean that we are spiralling inward towards the sun, or that in a mere 30 centuries, March 15th will be an autumn day in the Northern Hemisphere?

Can a gimbal be made of electromagnetic force? A map pin would be likely iron, and it seems to me that you could float it with an electromagnet. A magnet would be more convenient than flat lemonade, for some applications.

Would such a 'virtual' gimbal be less succeptible to earthquake (keeping a TGV train stably on track), materials stress due to a sudden jink (of a fighter plane, so the pilot can always know where she and her ordnance is)?
