Are these "artsy"? I sure don't think so. They aren't really "hard" sciences. Hm.
"Artsy" was a poor choice of term on my part, that's why I put it in quotes.
"Soft" and "hard", "artsy", "the arts", none of the terms seem to be truly descriptive.
I once worked closely with an electrical engineer as an electronics tech and I must say some of his circuit designs and problem solutions were so perfect I would have to describe them as art. To the point I got really excited, thinking to myself "Holy snot, look at the way the man thinks. His creations are pure beauty in form and function."
So, anyway.
