- the slow, conical motion of the earth's axis of rotation, caused by the gravitational attraction of the sun and moon, and, to a smaller extent, of the planets, on the equatorial bulge of the earth.
- precession of the equinoxes.

The new study also found evidence of phase precession outside of spatial tasks, lending some weight to the idea it may be a more general process in learning throughout the brain.
The researchers say more studies are needed to flesh out the role of phase precession in the brain, and how or if it contributes to learning is still uncertain.
Notably, the rate of that precession diverged slightly from the standard model expectation, physicists report April 7 in a virtual seminar, and in a paper published in Physical Review Letters.Muon magnetism could hint at a breakdown of physics’ standard model|Emily Conover|April 7, 2021|Science News
A radiofrequency pulse not only knocks protons down, but synchronizes their spins with each other, matching their precession frequencies into a coordinated group choreography.
After the pulse, the precession frequencies gradually become unsynchronized again as the protons return to their upright orientation, spinning off at different rates like dancers embarking on their solos.
This is due to what is known as "precession;" a slow movement of the axis upon which the earth rotates.The Astronomy of the Bible|E. Walter Maunder
Does the precession of the equinoxes have any effect upon the seasons or upon the climate of different parts of the earth?
Will the precession ever bring back the right ascensions and declinations to be again what they now are?
This slow movement forward of the goal-post is called precession—the precession of the equinoxes.Pioneers of Science|Oliver Lodge
Instruct the computer to discontinue precession operations that have been initiated.Where I Wasn't Going|Walt Richmond
