The Higgs boson explains why all particles have mass. The cosmological constant explains why the expansion of the Universe is speeding up. Yet both explanations suffer from a problem that theoretical physicists call “naturalness”. In this talk I will describe the Higgs boson and the cosmological constant and explain why both these phenomena are so very puzzling. Resolving these puzzles is one of the major open problems in theoretical physics.
