Unified field theory of (the not mathematically well-defined) quantum electrodynamics. One can extend this system to include the weak and strong nuclear forces to get the Einstein–Yang–Mills–Dirac System. The French physicist Marie-Antoinette Tonnelat published a paper in the early 1940s on the standard commutation relations for the quantized spin-2 field. She continued this work in collaboration with Erwin Schrödinger after World War II. In the 1960s Mendel Sachs proposed a generally covariant field theory that did not require recourse to renormalisation or perturbation theory. In 1965, Tonnelat published a book on the state of research on unified field theories. In 1963 American physicist
Unified Theory (band) to tour in support of their album. However, the tour was soon cancelled after Blind Melon parted ways with Warren. The band were to perform a number of shows with Thorn and Smith's former band mate Shinn, though a lack of preparation time resulted in the band cancelling the tour. Unified Theory released their second album "Cinematic" on iTunes in December 2006. The band did not reunite to perform any shows to promote the album. Unified Theory reunited for one show on August 4, 2010 at the King King in Hollywood. Chris Shinn's other band Everything is Energy opened the
