I accidentally stumbled on this interesting thread. Quite a few good input already. Count's work on the charts are well done.
I Ching trains the mind to function intuitively (key component for devination/prediction). Abstract thinking and fussy logic serve as the base. The first step towards that is to learn drawing the trigrams. This exercise is often omitted these days but is most important in developing a healthy foundation for future studies. By learning to draw the trigrams and arrange them in Bagua diagrams (landscaping and mapping), one would learn the delicately balance between spatial-temporal relations (physics) and the mind (metaphysics).
Without imagination, even if you have all the technologies necessary, you can not colonize Mars. But in order to do that, you first need to draw the plans. This is no difference in studying the I Ching.
