I recall about the same time as this "Invention" was announced that
someone else at NASA "Invented" a three footed spherometer. Although I
believe their great claim was in determining the radius of the feet by
measuring a series of certified master surfaces. I would have just
measured the spacing between the the feet and let Gauss and Pythagoras
give me the radius.
