Public Lecture im Rahmen des 5th Vienna Central European Seminar on Particle Physics and Quantum Field Theory Mitschnitt einer Veranstaltung am Freitag, dem 28. November 2008 im Hörsaal für Materialphysik der Universität Wien Moderation: Helmuth Hüffel Michael Creutz ist Professor für Hochenergiephysik am Brookhaven National Laboratory in Brookhaven, New York. Lattice gauge theory provides a mathematical formalism for first principles calculations of the interactions of quarks and gluons, the basic constituents of particles feeling the nuclear force. In this approach the paths of quarks through space-time are approximated by discrete hops on a lattice. The lattice itself is a mathematical trick, and at the end of the calculation the underlying spacing is extrapolated to zero. However, with the lattice in place the system can be studied via computer simulations. In this talk I review the history that drove particle theorists to this technique and become major supercomputer users.
