Giant chalkboard billboard in NYC has mystery equation begging to be solved... can you do it?

"Every significant event in the course of human history can be tied to a number…. ".. 'cuz we use this thing called dates, see, but that's neither here nor there and probably not the point Dow wants to make with their little poetical math-mystery.

The tumblr-site Giantchalkboard shows the progress of the equation which is being unveiled bit by bit on the corner of Broome and Crosby in SoHo. Here's a closeup of the start of the equation. People are invited to guess through twitter - @giantchalkboard - and the website about where this long equation is going.

"On the 5th day the answer will be revealed. This mathematical poem is the teaser to a new campaign from Dow."

@ADoholick just reminded me about the Google ads of yesteryear, which I badlanded in Two hard nuts to crack, or three as there were so many "puzzle campaigns" back then speaking directly to geeks that Texturl wrote a post asking is it time to pwn l33t ads?

If Dow's Giant Chalk billboard is done to attract skilled thinkers for a job at Dow remains to be seen. If it is, it will have a one-way ticket to Badland.
