you could look it up
i didn’t swipe this
when i drew this
… but of course the *idea* has been around for centuries.
i did *learn* a lot from _the_fundamental_concepts_of_geometry_
(bruce e. meserve). it’s a cheap dover reprint
and a masterpiece of clear exposition.
*everybody* oughta have one of these…
just like a bible, a shakespeare, and a dictionary. i’ll bet
the matching algebra book is good too… but i’ve got
*lots* of good algebra books.
