# Unification, Geometry and Ambivalence: Hilbert, Weyl and the Göttingen Community

Chapter

## Abstract

In 1918 the mathematician Hermann Weyl (1885–1955) extended the general theory of relativity that Albert Einstein (1879–1955) had set forth in the years 1915–1916. At one level, Weyl’s theory made it possible to unify the two field phenomena known at this time, namely those described by electromagnetic and gravitational fields. But more was at stake. At the beginning of the paper in which Weyl worked out the mathematical foundations of the theory, he observed that:

According to this theory

everything real, that is in the world, is a manifestation of the world metric; the physical concepts are no different from the geometrical ones. The only difference that exists between geometry and physics is, that geometry establishes in general what is contained in the nature of the metrical concepts, whereas it is the task for physics to determine the law and explore its consequences, according to which the real world is characterized among all the geometrically possible four-dimensional metric spaces.
