TED-Ed: Can you solve the troll’s paradox riddle? - Dan Finkel

In this video, you and your brother explore the realm of Paradoxica, encountering a troll that captures creatures. The troll challenges you with a paradoxical logic puzzle: say something true to free the creatures or something false to free your brother. Using coercive logic, you craft a statement that forces the troll to release both your brother and the creatures. This solution, inspired by Raymond Smullyan, demonstrates the power of logical reasoning. The creatures celebrate their freedom and promise to lead you to treasure.
