Introduction to String Theory Chapter 0 ETH Zurich, HS13 Prof. N. Beisert, Dr. J. Br odel 22.12.2013 0 Overview String theory is an attempt to quantise gravity and unite it with the other fundamental forces of nature. It combines many interesting topics of (quantum) eld theory in two and higher dimensions.

String Theory I - TU Wien

hep.itp.tuwien.ac.at

String unification apparently works in a rather different way: Here the fundamental object is a thread or a loop in space-time which, during time evolution, sweeps out a surface that is called world sheet (in analogy to the world line of a point particle). The dynamics is described by an ... String Theory I ...
