Peter Zimmerman, late of King’s College London, sends along a challenge that I am calling “wonk school.”

Peter proposes a series of take-home exams to see how well various readers do analyzing overhead images. And, as an inducement, he is offering to buy a pint of (good) beer for the best answer to the exam at a tavern of my choosing in Dupont Circle.

This is a take-home examination; There is an honor code. Send answers to: peter.zimmerman [at]

The full text of the assignment is in the comment section.
