[playing with the identity problem ...]
You have two spheres of identical dimension, mass,
colour, surface, sound, fragrance, etc. etc.
One is solid throughout, with a uniform mass distribution,
while the other has a hollow center.
Is it possible to determine (in a non destructive
manner!)which is which? How?
