For nearly 36 years I’ve watched Dave twirl on dramatically in speech and beyond. Sometimes I chime in as though there were something to add. I’ve updated this post because of the YouTube video embedded below the image, Dave, A Sprial. The video is entitled I Wish I’d Had a Science Teacher Like This. Dave is the math teacher I wish I’d had. Fortunately, he’s the friend I do have, the gentle poet who spirals on gracefully.
