Pascual JordanDied 31 Jul 1980 at age 77 (born 18 Oct 1902).Ernst Pascual Jordan was a German physicist who in the late 1920s co-founded (with Max Born and later Werner Heisenberg) quantum mechanics using matrix methods, showing how light could be interpreted as composed of discrete quanta of energy. Later, (with Wolfgang Pauli and Eugene Wigner), while it was still in its early stages of development, he contributed to the quantum mechancs of electron-photon interactions, now called quantum electrodynamics. He also originated (concurrently with Robert Dicke) a theory of cosmology that proposed to make the universal constants of nature, (such as the universal gravitational constant G), variable over time.[Image: Heisenberg (L) with Jordan (R)] |
