[A]nother interpretation holds that Relativity requires only thatTheories be Lorentz invarient. - Tim Maudlin

[T]he most general question we can ask about matter is what sort of thing it is. ...[W]e might hold that matter is made of point-like particles, or of fields, or of one-dimensional strings, or of some combination of these, or of something else altogether. Given any of these ...there are further, more specific questions ...We will be concerned with the most general questions, rather than the more specific ones.

The sparks which fly when quantum theory collides with Relativity ignite conceptual brushfires of particular interest... problems about causation, time, and holism. Unfortunately much of the work... presupposes a considerable amount of familiarity with the physics. This is particularly sad since the physics is not, in most cases, very complicated.

The central problem facing attempts to understand a quantum theory is how it manages to model empirical phenomena in a principled way. This is often referred to as "the measurement problem"...
