I'm not the worst offender, though. A lot of the explanations you hear
about physics have as much merit as the Friday afternoon stock market
guy 'explaining' what happened on Wall Street that week. The idea that
an electret mic is a variety of capacitance mic is one example... snip


OK, I'll bite: What's wrong with explaining electrets as
permanently polarized capacitance mics? Are you saying
that this is *not* the basic concept, or that it just
doesn't go deep enough to do justice?

Like the various "electricity as a flowing liquid"
analogies, sometimes a flawed analogy can nevertheless help
get a basic concept across... as long as it's clear that it
is an analogy and not an equivalence.
