Three things affect the trajectory of a curve ball: Coriolis effect, gravity and precession AKA spin drift.
Earth's precession
"sh aka" has no meaning in Hebrew.
precession
Precession, which in this case refers to a movement of Earth's axis. A full "turn" takes about 26,000 years.
An ayanamsha is a degree of precession in Vedic astrology.
Precession refers to a gradual change in the direction of Earth's axis of rotation.
There is no Larmor precession without magnetic field
Precession of the equinox.
The abbreviation is spelled AKA, meaning 'also known as' (i.e. an alias or pseudonym).
The Earth is a spinning top (gyro) with a different moment of inertia about the spin axis than the other two axis. Therefore, it acts like a spinning top with both precession and nutation. Precession of the polar axis (relative to a 'fixed' distant star) forms a cone. The precession period (~26,000years) is the time it takes for the cone to be traced. Nutation occurs normal to the precession cone and has a much faster period (~18.6yrs).
