The scientific community mourns the passing of physicist François Englert. In 1964, Englert and his collaborator Robert Brout formulated the existence of an elusive subatomic particle. This particle is fundamentally responsible for conferring mass to other particles. Without this mechanism, the universe as we know it would not exist. His theoretical work laid the groundwork for the discovery of the Higgs boson. Englert's contributions remain a cornerstone of modern particle physics. He is remembered for his profound impact on our understanding of the cosmos.
