Gerardus ‘t Hooft’s Nobel Prize was for ‘elucidating the quantum structures of electro-weak interactions’. In this film he meets cosmologist, Benoit Famaey, and theorists Vincenzo Calo and Kristen Koopmans. He tells them that the world of science is littered with wrong ideas, but as young scientists they must not be frightened to publish theirs wherever they may lead.
