Readers will painlessly learn about concepts such as first-order and second-order logic, the Banach-Tarski paradox
, the Von Neumann universe, G|delAEs incompleteness theorem, and the Cantor-Bernstein theorem.
The Banach-Tarski paradox
, string theory, Klein bottles, and universes where time runs in reverse are some subjects explored.
Far more mind-blowing is a mathematical result known as the Banach-Tarski paradox
after two Polish mathematicians, Stefan Banach and Alfred Tarski.

Pawiikowski (1991), The Hahn-Banach theorem implies the Banach-Tarski paradox
However, even by the time he came to the US, Tarski was already established as a master in such matters as the Banach-Tarski Paradox
(in which a sphere of any size can be cut up into a finite number of pieces and re-assembled into a sphere of any other size) and his advances in logic and set theory.
