Prof Lawler defines 'dimension' on p 11 of 20. However, I don't understand or can't imagine the difference in dimension between the verbs for 2D and 3D above. For example:
[4.] A scrawl is written on a thin parchment or papyrus; so the 'height' of the writing material seems trivial. So should a scrawl be 1D?
[5.] How is a cap 2D? Similarly, how is a chap 2D? Humans (including chaps) can jump, and so can move along the z-, beyond the x- and y-axes.
[8.] How is a stump 3D, but a wall (in 4) 2D?
