Einstein and Michele Besso calculated Mercury's anomalous perihelion motion with the provisional gravitational theory, creating a detailed test that the Entwurf equations failed to reproduce correctly.
The Entwurf collaboration introduced provisional field equations intended to connect the spacetime metric with matter, giving Einstein a concrete but still incomplete relativistic theory of gravitation.
Einstein's developing theory treated the metric field as physically determined by matter and energy, moving the gravitational problem toward the geometry-source relationship later embodied in his final equations.
Einstein and Marcel Grossmann published the Entwurf theory, an intermediate gravitational framework that used tensor methods but did not yet possess the full general covariance of general relativity.
Einstein developed the hole argument as a reason to distrust unrestricted general covariance, a position he later abandoned when completing general relativity in 1915.
Receives the Nobel Prize in Chemistry for work on the linkage of atoms in molecules, especially inorganic compounds.
