It occurred to me today, after a failed attempt at sketching the exterior surfaces of a barn, that straight lines interest me in only the most academic of settings, those being, for instance, ones in which the initial value of a dynamic system is followed spatially by a series of points - an infinite set placed infinitely close (which is to say that space is infinitely divisible [as can be seen by one of Zeno's paradoxes]) - indicating the rate of growth or decay of said system, but in the absence of curve, a barn drawing becomes (quite tediously) nothing more than an exercise in determining the spatial relationships (e.g. distances, angles of intersection, and so on) of a finite set of straight lines, which is why, upon closer inspection, I'm left wondering whether or not sketching the exterior surfaces of a barn is more of an academic endeavor than I had originally figured it to be and, by that very property, deserving of greater consideration w/r/t its similarity to, let's say, determining the degree measure created when extending the side of a closed figure, and so I find myself now confronted by a paradox (dilemma? quandary?) that I have not the energy to decode and so I'll defer to the reader.
