Abstract
A solid sphere can be decomposed into 5 sets
such that by translation and rotation these 5 sets can be rearranged
to form two solid sphere of the same radius as the original sphere.
I will explain this mind boggeling result, and along the way show how
mathematicians explore the strange world of the infinite.
