Findings

Einstein's 1916 equations included an extra trace term.

He used the condition √-g=1 in his derivation.

The paper traces the evolution of Einstein's field equations.

Abstract

I discuss Albert Einstein's 1916 General Theory of Relativity. I show that in Einstein's 1916 review paper, "the Foundation of the General Theory of Relativity", he derived his November 25, 1915 field equations with an additional term on the right hand side involving the trace of the energy-momentum tensor (he posed the condition square root -g=1) using the equations he presented on November 4, 1915.
