Unified Theory (band) Thorn and Shinn then regrouped with Smith and began recording material. It was during recording that Smith invited friend, and former Pearl Jam drummer, Dave Krusen to record with them, with Krusen eventually joining the lineup permanently, forming Luma in mid-1998. The following year, they released a four-song self-titled EP through their website, and toured the Pacific Northwest from July 29–August 18, the same year. By the end of the year, Luma changed their name to Unified Theory, named after Albert Einstein's final hypothesis unified field theory. By 2000, Unified Theory signed with Universal Records subsidiary 3.33 Music Group while
Gauge theory of certain topological invariants (the Seiberg–Witten invariants). These contributions to mathematics from gauge theory have led to a renewed interest in this area. The importance of gauge theories in physics is exemplified in the tremendous success of the mathematical formalism in providing a unified framework to describe the quantum field theories of electromagnetism, the weak force and the strong force. This theory, known as the Standard Model, accurately describes experimental predictions regarding three of the four fundamental forces of nature, and is a gauge theory with the gauge group SU(3) × SU(2) × U(1). Modern theories like string theory, as
