It would've stumped Einstein: the missing-pen-by-the-phone theorem

From the Christian Science Monitor:

NEW YORK – Yeah, yeah, this is the 100th anniversary of Einstein's "Miracle Year" - the year he figured out everything from relativity to atoms to e=mc2. So how come Mr. Genius never bothered to explain the deepest physics mystery of all: Where does the pen by the phone go?"

Ms. Skenazy questions a group of physicists -- and a professional organzier -- to help her solve the mystery!
