Yesterday my husband thought he saw a cockroach in the kitchen. He sprayed everything down and cleaned thoroughly.
Today I’m putting a cockroach in the bathroom.
Hermann WeylBorn 9 Nov 1885; died 8 Dec 1955 at age 70. Hermann Klaus Hugo Weyl was a German-American mathematician whose widely varied contributions in mathematics linked pure mathematics and theoretical physics. He made significant contributions to quantum mechanics and the theory of relativity. He attempted to incorporate electromagnetism into the geometric formalism of general relativity. Weyl published Die Idee der Riemannschen Fläche (1913) which united analysis, geometry and topology. He produced the first guage theory in which the Maxwell electromagnetic field and the gravitational field appear as geometrical properties of space-time. He evolved (1923-38) the concept of continuous groups using matrix representations. Applying group theory to quantum mechanics he set up the modern subject.« |
