回答: btw, morden gyroscope uses laser to replace the moving part. 由 steven 于 2005-5-08, 13:17:03:
to be curious about the toy. From this magic toy I learned a bit about the classical mechanics. The laser is really beyond my ability to learn. I guess there must be something about angular deflection that a laser beam can detect. Technology especially the precision technology is the king of money. Thanks a lot for letting me know what is inside of a modern gyroscope.
