It does not matter where you live, you must have seen one of the container boxes on a truck flying through the highway. If you ever visit a major port, you will see hundreds, if not thousands, of these container boxes stacking on top each other sitting on a huge ship that is moving slowly on the ocean. (I still don't know why did such ship can float in the ocean).
From the dock, dock workers, transportation, just in time development, to commerce between countries, this box was part of them.
Little did I know these boxes that I see everyday is so important until I read The Box by Marc Levinson.
