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
Field (physics) of jet manifolds (covariant classical field theory). In modern physics, the most often studied fields are those that model the four fundamental forces which one day may lead to the Unified Field Theory. A convenient way of classifying a field (classical or quantum) is by the symmetries it possesses. Physical symmetries are usually of two types: Fields are often classified by their behaviour under transformations of spacetime. The terms used in this classification are: Fields may have internal symmetries in addition to spacetime symmetries. In many situations, one needs fields which are a list of space-time scalars: (φ, φ, ...
