Darrin W.S. Belousek, Ohio Northern University

Abstract

This paper considers an unpublished manuscript written by Albert Einstein in 1927 that contains an unsuccessful attempt to provide a deterministic hidden-variable completion of quantum mechanics. After laying out the formal scheme of the manuscript and developing its interpretation, its background, context and significance are discussed, particularly in regard to the impact of the failure of the scheme on Einstein's ensuing thoughts concerning the possibility for a complete quantum mechanics.
