As a girl I didn't grasp the genius of the Periodic Table until I read a science fiction story about it. It concerned an Earth exploration group that had landed on once-inhabited planet but could make no sense of the language or culture of the long-dead creatures. Then a young woman with the exploration team recognizes the Periodic Table, which becomes a Rosetta Stone for them. The point was that the table was not merely our convenience but a universal truth. I wish I could remember the name or author of the story, but it was many years ago.
That story is "Omnilingual" by H. Beam Piper. Excellent story, excellent author.
