Regions containing different states in a simple field or substance

  1. Sep 20, 2014 #1
    I am writing a book, and since I am a science layman, just wanted to check to see if you find the following paragraph I wrote to be correct from a physics standpoint. The idea here is that "a single, simple substance or field can contain regions which are in different states." I would greatly appreciate any suggested corrections! Or if you can think of some better examples of this, please let me know.

    "A single, simple substance or field can contain regions which are in different states. For instance, a magnetic recording can be stored on a continuous length of steel wire (this technology is known as wire recording). An example from theoretical physics is when a wave propagates through a field. That wave is believed to consist of variations in the strength of the field. In other words, different regions of the field are existing in different states. Particle-antiparticle pairs and vacuum field fluctuations are another example from theoretical physics of different regions of a field existing in different states. Regions holding different states can interact with each other, such as when particle-antiparticle pairs cancel out, or coherent light produces interference patterns. The number of possible states and how the regions which hold those states interact depends upon the nature of the substance or field."
