Classical unified field theories a survey of classical relativistic field theories of gravitation that have been motivated by theoretical concerns other than unification, see Classical theories of gravitation. For a survey of current work toward creating a quantum theory of gravitation, see quantum gravity. The early attempts at creating a unified field theory began with the Riemannian geometry of general relativity, and attempted to incorporate electromagnetic fields into a more general geometry, since ordinary Riemannian geometry seemed incapable of expressing the properties of the electromagnetic field. Einstein was not alone in his attempts to unify electromagnetism and gravity; a large number of mathematicians and
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".
