@. What does the ball suspended in
the National Academy Of Sciences
prove?-P. D.
A. The suspended ball to which you
refer is Foucault pendulum. The ac-

ton, freely swinging pendulum tends
constantly to move in the same plane.
The experiment proves that the earth
rotates eastward, and the rate of devia-
ton Of the pendulum proves that the
relative motion Of the earth with re-
spect to the stars Is due entirely to its
rotation and not to the motion OF the
stars around it.
