The Banach-Tarski Paradox:<br>

The Banach-Tarski Paradox is an interesting consequence of the
"controversial" axiom-of-choice.  It states the it is possible to
"cut" the solid ball in 3-dimensional space into finitely many
pieces and reassemble them to make 2 solid balls each of the same
volume as the first.  In this talk we will investigate this pardox
and give a sketch of the proof.  This talk will accessible to
anyone.
