Louis de Broglie generalizes wave-particle duality by suggesting that particles of matter are also wavelike. Wolfgang Pauli enunciates the exclusion principle. Werner Heisenberg, Max Born, and Pascual Jordan develop matrix mechanics, the first version of quantum mechanics, and make an initial step toward quantum field theory. 1923 1923 1925 1925
