 Great column, but AFAICT it was never written by Martin Gardner.  IIRC
 most of the Amateur Scientist columns I read were written by C.L. Strong.

Ummm, C. L. Stong - no 'r'.  I absolutely loved that column as long as
C. L. wrote it.  Somewhere, I have a CD containing most or all of them.
  BTW, I made the same mistake of thinking Gardner did some of the
Amateur Scientist columns too, but evidently he did not.  While I'm
confessing, I thought for the longest time that Mr. Stong did those
marvelous drawings that graced his columns, but I learned later that I
was wrong about that too.  I don't know which was better, the text or
the drawings, but they were both marvelous.  I still think it would be
fun to build one of his "short pendulum" seismographs some day.
