Self-organizing architectures showed to be able to deal with this complexity by making global system features emerge without central control or the need of excessive computational power. Up to now research has been mainly focusing on identifying self-* techniques t

Supersymmetry and Supergravity,ogical next step in the historical road towards unification in fundamental physics. String theory is the best-understood model of quantum gravity (or indeed the true theory underlying quantum gravity) and its stable versions all rely on SUSY (in 2d and in 10d). The only presently controlled roads fr

String Theory: Interactions and Superstring,rst, we want to understand at least in principle how scattering amplitudes and loop effects are calculated. Second, we need to introduce fermions and get rid of the tachyon. The main textbook sources continue to be.

Concluding Remarks and Some Alternative Perspectives,ould and maybe should have been covered but had to be left out for reasons of space or, more precisely, because they will most likely not fit in the time frame of a one-semester course. Moreover, part of the comments and ideas collected in this section lead away from the specific ‘string landscape p

Summary,eory with a number of issues: too many (and too random) parameters, especially in the Yukawa sector; no dark matter candidate; no mechanism for producing the baryon asymmetry of the universe; no obvious inflaton candidate. Moreover, and this was our central theme, one faces a hierarchy problem conce
