The spin wobble period of the earth, the 25,800 year period known as the Great Year or Platonic Year, provides a precise measurement of the torque forces operating on the earth.

Celestial Mechanic wrote the precession dialogues (http://www.bautforum.com/astronomy/35528-precession-due-equtorial-bulge-2.html#post635506) which explain the science of the torque of the earth.

I'm posting this to enquire further regarding the exact science of the torque of the earth. More than 99% of the precession is understood as resulting from lunisolar torque. I would be interested in scientific comment on the remaining factors causing precession and its rate of change.

Any puns on torque of the earth would be welcome, such as from Mahler (http://en.wikipedia.org/wiki/Das_Lied_von_der_Erde) or the talk of the town (http://www.newyorker.com/talk), all torque and no binary. :lol:
