Geometry, trigonometry whatever. The fine points of
your "non-Euclidean" are of some interest though. I
take it up on more detail in geometry-pre-college:

Joe Clinton showed me the spherical trig books that
used to get air time pre the big push to gateway
everyone through Calc (moooo!). Fast Food Nation

Yeah, a presumptuous class thing. As we're learning in
South Africa, it makes perfect sense to get young boys
on the water, sailing, before they get recruited into
landlubber gangs, and a lot of distracting politics
(Lara did an excellent story about this awhile back on
CBS -- she's chief foreign correspondent and an RSA

Navigation arts make a big come back in my scenario. We
don't *let* it "die on the vine" they way they did in
the dark ages 1900s (but then they didn't have the GIS/
GPS tech we now take for granted, poor slobs).

I'm glad you too feel secure in your model. Nice isn't
