Re: Inertial vs gravitational mass

[Bernard Cleyet <anngeorg@PACBELL.NET>]

I heard a squeak.

Balance (equal arm); one mass (weight) is lead the other aluminum.  Stays
"balanced" when the elevator accelerates.

Also in the elevator is (was) a spring scale "accelerometer".   I suppose
two of them with different materials for the "weights" would also show
equivalence of different matter.  I proposed to the building honchos at
UCSC that I install a bathroom scale in the Nat. Sciences II elevator
along with the two above.  They OK'd it, but I never got around to doing
it.  This did add to my "kooky" reputation.
