Newton's law give no hint, and have no clue as to why the direction of a gyroscope's angular momentum vector desires to remain unchanged with respect to the rest of the universe in the first place. Or what type of field, if any, that angular momentum field is coupling with in order to maintain its orientation to the universe > > This desire even counteracts the force of gravity. As long as the angular momentum vector's magnitude (not it's direction) remains unchanged, the free end of a gyroscope will not fall in a gravitational field. Instead it will precess at the at a constant z coordinate value and maintain a constant gravitational potential. Why the free end of the gyroscope desires to precess instead of desiring to fall to a lower gravitational potential, is a complete mystery to modern mechanics. from where i'm standing the sun rotates around the earth and the moon. -- The Starmaker -- To question the unquestionable, ask the unaskable, to think the unthinkable, mention the unmentionable, say the unsayable, and challenge the unchallengeable.
