  As part of condensed-matter physics, the field of Anderson localization
concerns the study of conductance of electrons in a random medium. We summarize
and explain the results obtained in "A new numerical approach to Anderson
(de)localization" from a physics perspective. Further, we discover a
relationship with the so-called Thouless criterion - a dimensionless scaling
parameter often used as the sole indicator whether or not the system exhibits
Anderson localization.
