What do you mean by fundamental here? For studying astronomy at an university? Then yes, agreed, but I am wondering about the very basic understanding of the principles at all, are you implying that kids today don't learn this anymore? You know, what our solar system is, what the earth is, and it's, well, shape..

This particular cycle was not taught in the Astronomy PhD courses where I attended. Your comment near the top of this thread appears to claim that it's a part of 'basic astronomy'. That is not correct. The precession of the equinoxes is basic astronomy.

(Ha. Firefox's spellcheck doesn't have "precession" in it.)
