Classical unified field theories a survey of classical relativistic field theories of gravitation that have been motivated by theoretical concerns other than unification, see Classical theories of gravitation. For a survey of current work toward creating a quantum theory of gravitation, see quantum gravity. The early attempts at creating a unified field theory began with the Riemannian geometry of general relativity, and attempted to incorporate electromagnetic fields into a more general geometry, since ordinary Riemannian geometry seemed incapable of expressing the properties of the electromagnetic field. Einstein was not alone in his attempts to unify electromagnetism and gravity; a large number of mathematicians and
Unified Theory (band) only. "Unified Theory" went on to sell over 16,000 albums by 2002. "California" and "Wither" were both released as singles. However, with the exception of Seattle, most major market radio stations avoided playing "California." Critically, the album received generally positive reviews. Reviewing for Allmusic, Greg Prato stated that "Unified Theory's self-titled debut shows that Shinn has brought a more modern rock sound to the proceedings, mixing Jeff Buckley and Radiohead with Smith and Thorn's retro rock stylings" and that the "12-track debut is a refreshing break from the norm." Lina Lecaro, of the "Los Angeles Times", describes the album as
