Wow. This is a great article.<p>When I took art classes in college, I was eternally frustrated. Every instructor would parrot a variant of, "here's what you should do to be a good artist, but remember: art can't really be taught because it's all subjective." And that drove me nuts. It was as if everyone teaching art just admitted that they didn't know how to teach art, but they were still more than happy to take my tuition money. As an artist who loves science, that just wasn't enough for me.<p>After reading this article, a bunch of critical and much-needed things effortlessly dropped into place. Thanks!
