Re: vector products

Many years ago I posted to this list a discussion of gyroscope precession
that invoked neither pseudovectors nor GA, but just elementary notions of
force and change of momentum.

It seems we can introduce the terminology of wedge products at least when we
deal with torque in physics I, no? I think that at that point the bivector
idea actually fits better than the psuedovector idea.

I'd like someone with more knowledge of GA to explain how one might go about
discussing torque in a freshmen physics class. That would help me.

Not before?

I'd like to see how to present GA to high school students, and then to
college freshmen, and _then_ to students who have had linear algebra.

All the papers about GA I've downloaded from the web have professional
physicists as their audience, not lower-division students.
