There is quite a bit more to condsider, even just In the examples you provided. E.g. the abstraction of numeracy. http://www.edwardtufte.com/tufte/books_vdqi

E.g. the abstraction of numeracy. http://www.edwardtufte.com/tufte/books_vdqi http://www.edwardtufte.com/tufte/books_vdqi Also, Physics: The arch. A triangular truss. A lever. Also, Architecture: Lines, planes, volumes. These are some very basic (perhaps 'unremarkable') everyday uses of geometry. I don't think at all the fact that they are rudimentary is a problem. Because they are so pervasive, it is all the more important to have mastery of the subject. IMHO.
