Classical unified field theories describe the properties of the electromagnetic field as a purely geometric phenomenon. Einstein tried to form a generalized theory of gravitation that would unify the gravitational and electromagnetic forces (and perhaps others), guided by a belief in a single origin for the entire set of physical laws. These attempts initially concentrated on additional geometric notions such as vierbeins and "distant parallelism", but eventually centered around treating both the metric tensor and the affine connection as fundamental fields. (Because they are not independent, the metric-affine theory was somewhat complicated.) In general relativity, these fields are symmetric (in the matrix sense), but
Unified Fire Authority contract cities in addition to the Unincorporated Salt Lake County. These cities wanted to play a more active role in the fire administration. In 2004, the department ceased operation as a County government entity and became the Unified Fire Authority. The Unified Fire Authority is the sponsoring agency of Urban Search and Rescue Utah Task Force 1, one of the 28 FEMA Urban Search and Rescue Task Forces in the United States. Managed daily by full-time staff of Unified Fire under the direction of the Federal Emergency Management Agency - Urban Search & Rescue, Response Directorate/Operations Division. Adopted Budget 2017
