Any real Navigators left?
This is probably not Tech Log but it's the most likely place to get a sensible answer. Can anyone explain to me the Earth's 26,000 year precession. As I understand it the Earth 'wobbles' with the poles describing a circle. 26,000 years for a full cycle. What I want to know is where are we now, in the cycle, and what is the magnitude of the wobble.
