Thinking about a Carnival of Mathematics
It’s a new blog to me. The authors are A (computer science) and Z (physics). Subtitle: “critical analysis and interesting ideas.” Self-description of content: “commentary on all manner of topics — politics, society, science, morality, religion, and whatever else comes to mind.” So, the writing’s good. While your looking at the Carnival, and trying the puzzle, you might take an extra peek around.
Puzzle? Yup. Just for fun, he (she? they?) leads off with a combinatorial poser (39 people sitting around a circular table, none in the right place…) (Looks combinatorial, but might bend quicker to algebra).
Reminds me of this old problem, that appears never to have gotten a general solution on this blog. I’ll repost, soon.
