I am vastly amused by today's xkcd cartoon, showing the electromagnetic spectrum in great detail, plus "other waves."

This may have something to do with the amount of time I've spent editing and proofreading lessons on the subject since February.

I've seen many versions of such diagrams in my time, but that one is better than all of the rest.
