Paris, May 29, 1832. On the eve of a duel, Évariste Galois, barely in his twenties, put pen to paper for the last time on a manuscript filled with equations and theorems. That manuscript, which he had written over the previous four years, marked the beginning of an extraordinary scientific adventure that radically changed the way we view the world, providing us with the ideal language to unveil the fundamental laws of the Universe. Genius and rebellious, Galois is the quintessential romantic hero.
