Possibly the best five minute explanation I've seen in recent years.
In view of the typical attention span for people at large to tolerate an explanation of the practical everyday mechanics of how USG works, this is an excellent treatment. Extra kudos that it explains in the kind of quick drive thru style that fits with the prevalent pop culture method of how to view the world AND done with simple terms that are probably within the vocabulary and capacity for lay people young and old to comprehend.
Upon visiting the linked websites , the mentioned references to the Princeton study are either not there or there but not apparent. Would be nice to know why the study was done; was it a typical - official - commissioned study and if yes who or what was the impetus behind commisioning it and are there sample citations that were, for instance, the basis for this 5 minute video?
