Ramsey and his colleagues began by putting very slow neutrons in a weak magnetic field, causing them to precess like tops. These spinning neutrons were directed through a strong electric field which would cause a dipole to change its precession frequency. However, the physicists recorded no change in the spinning of the neutron...
...launched into a 500-mile-high polar orbit. It will carry a virtually perfect gyroscope-one that is almost completely free from friction, gravitational pull or magnetic fields. If the general relativity theory is correct, according to calculations made by Stanford University Physicist Leonard Schiff, the gyroscope should precess-change the direction of its axis of rotation-about 1/500th of a degree each year that it is in orbit. This gradual and almost imperceptible change would be caused by the continuous passage of the gyroscope through Einsteinian space, which is "warped" by the earth's gravitational field...
