Paradox is a guided tour of puzzles that have shaped logic, science, economics, mathematics, and philosophy�told in verse and unpacked in prose. Each paradox is introduced as a formally rhymed poem, followed by a concise explanation that makes the underlying idea clear without sacrificing rigor. Along the way, readers encounter liars and barbers, time-travelers and twins, markets that fail because they work too well, infinities that misbehave, and arguments that collapse under their own logic. Some paradoxes are resolved; others are not. All are illuminating.
