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 primary Primary For All Candidates." Several variations of this measure have been filed to date: 2014 Initiative Petitions 38 and 51. The campaign did not collect the 87,213 signatures required to get Petition 54 onto the ballot. (The "Open Primary" proposal that used plurality voting did collect enough signatures, but was defeated.) Frohnmayer later joined the campaign for STAR voting, an alternate voting method which would replace blanket/unified primaries with a single election that uses a score ballot and automatic runoff, though still promoting the unified primary under the name "Equal Top Two". Unified primary A unified primary is a proposed
