Anyone notice that most of these "How it" whatever websites,
Discovery channel shows, and such, get the physical aspect of
manufacture down (duh, they are filming it), but they always seem
to pull something out of their butts when trying to explain the
science behind how something works? I think this is caused by
having professional writers only having a limited knowledge of
what it is that they are writing about, and winging it when an
item of confusion comes along. Peer review of the final script
obviously is not in the cards.
