``Lorentz Force Law'' by wmccutchen on 2008-09-08 01:00:14
The recent entry for the Lorentz Force Law illustrates why physics teaching is failing: no examples illustrating the rule for calculation, no unit of measurement for the force (Newtons?), no explanation of why opposite charges go opposite directions, no practical applications, just an opaque formula that is unintelligible to a beginner.  That's not enough, and it just makes the beginner think that learning physics is impossible and irrelevant.  Reminds me of Luke 11:11.  When students need bread, it is cruel to give them a rock to chew instead.
