Nice one...that brings me right back to high school physics and one of the few things I got! And, I even remember a friend of mine who was brilliant in physics back then (and still is--he's been an astrophysicist at Harvard for 35 years) who said at the time that the inverse square law speaks for a designer's presence. He said "Why should it be exact whole numbers?" Why isn't it 1.769274 or somesuch?"
Made me think...
