Contribution

It provides a non-technical overview of key developments in noncommutative geometry related to fundamental interactions, emphasizing German contributions and recent progress.

Findings

Noncommutative geometry offers new insights into fundamental interactions.

Connections between noncommutative field theory and string theory are acknowledged.

German contributions have significantly advanced the field.

Abstract

This is the full text of a survey talk for nonspecialists, delivered at the 66th Annual Meeting of the German Physical Society in Leipzig, March 2002. We have not taken pains to suppress the colloquial style. References are given only insofar as they help to underline the points made; this is not a full-blooded survey. The connection between noncommutative field theory and string theory is mentioned, but deemphasized. Contributions to noncommutative geometry made in Germany are emphasized.
