Physics Colloquium, November 8, 2005Unification of fundamental interactionsHans-Peter NillesUniversity of BonnSymmetries have played a crucial role in the development of the standard model of particle physics. Moreover, they are believed to provide the key ingredients for a unified description of all fundamental interactions. Observational and theoretical arguments lead us to the consideration of grand unified gauge symmetry and supersymmetry. We review the arguments that favour the investigation of these mathematical structures and explain possible consequences for particle physics and cosmology.
