    This is a wonderful video that introduces Magnetics.  Most of this stuff is normally taught in a Physical Science class.  When you  watch this video, don't forget to THINK!!!

    this guy is a little crazy, but he does a nice job of emphasizing that the concept of "Field" is man-made to help us understand how forces can act over a distance.

Only 6 Black girls in the entire U.S. in 2008 got 5's on Physics C

A few years ago, I scolded an advisee of mine for pulling out of a leadership position (house president).  Her reason was that she thought she had no chance of winning.  Only one other person ran---and got the position by default.  My advisee happened to be Black young woman.  I told her that because of the history of our country and some facets of its current state, persons from certain demographic groups do not have the luxury to give up leadership positions.  A few days ago, I saw a similar situation develop, but this time in an Honors Physics class.  Upon researching some statistics, I found an article on "Who Gets 5's on AP Physics Exam" in the blog http://isteve.blogspot.com by Steve Sailer.  (Disclaimer: I take no position on any view expressed by Sailer or his blog.)
