This talk was given at a local TEDx event, produced independently of the TED Conferences.

What would happen at school if instead of learning what we have to learn, we learn what we want to learn? Santiago Aranguri, only 14 years old, tells us all he learned while he was doing an application to look for missing persons. In cooperation with the NGO "Personas Perdidas", he developed a platform to help search for missing people, creating the necessary tools to achieve their prompt identification. He is a math riddle enthusiast and an active participant of national and international Mathematical Olympiads.
