=== Unified field theory ===
{{Main|Classical unified field theories}}
Encouraged by his success with general relativity, Einstein sought an even more ambitious geometrical theory that would treat gravitation and electromagnetism as aspects of a single entity. In 1950, he described his [[unified field theory]] in a ''[[Scientific American]]'' article titled "On the Generalized Theory of Gravitation".<ref>Einstein (1950).</ref> His attempt to find the most fundamental laws of nature won him praise but not success: a particularly conspicuous blemish of his model was that it did not accommodate the [[strong nuclear force|strong]] and [[weak nuclear force]]s, neither of which was well understood until many years after his death. Although most researchers now believe that Einstein's approach to unifying physics was mistaken, his goal of a [[theory of everything]] is one to which his successors still aspire.<ref>{{Cite journal |last=Goenner |first=Hubert F.
