Re: vector products



I wrote

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.

to which Jack Uretsky responded:

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.

Just to clarify...I have no problem discussing gyroscope precession without
invoking psuedovectors or any algebra at all (just N3 and ideas about
rotation). [Hmmm...does that mean I am using GA without realizing it?]

In any event, my request is for someone to show the difference between, say,
defining torque as r/\F vs. rxF. Would the presentation or treatment be any
different? How so?
