Classical unified field theories accepted by physicists. Classical unified field theories Since the 19th century, some physicists, notably Albert Einstein, have attempted to develop a single theoretical framework that can account for all the fundamental forces of nature – a unified field theory. Classical unified field theories are attempts to create a unified field theory based on classical physics. In particular, unification of gravitation and electromagnetism was actively pursued by several physicists and mathematicians in the years between the two World Wars. This work spurred the purely mathematical development of differential geometry. This article describes various attempts at formulating a classical (non-quantum), relativistic unified
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".
