Today’s ad from the ThinkGeek folks offers a Batman t-shirt:

A complex play on the periodic table of the elements.

The figure on the shirt has the table’s entry for sodium (Na, atomic number 11) 16 times, or as ThinkGeek geekily has it, Sodium * 16, representing two repetitions of an 8-note instrumental figure in the theme song from the television show:

This is followed by an entry for Batmantium, with the Batman logo from the movies —

(which can be seen as a black bat on a gold background, or as gold teeth on a black background, but in the ThinkGeek version is only a bat ), representing the Batmaaaan! in the theme song.

The table entry has the atomic number 27 (normally assigned to Co, cobalt) and the atomic weight 19.39. This is a little comics joke: as the Wikipedia entry for Detective Comics tells us, the series is

best known for introducing the iconic superhero Batman in Detective Comics #27 (cover dated May 1939)

#27, 1939, get it?

      This is explained quite clearly in the posting.

        I imagine what is not clear — I had the same question — is how the tiles are arranged that the Batmantium tile appears in the 27th position; huge coincidence! But upon magnifying the image, I see that the tile itself gives #27 and atomic weight 19.39; that’s the joke, no coincidence involved. The entire tile is fictional, not just the element name.
