Entropy as Information

In our discussion, entropy is a measure of the number of rearrangements of an object’s internal constituents, which have no effect on its appearance. So, entropy is the amount of information that can be stored in a system, without showing it as a different system. The storage is represented by capacity that a system internal may be arranged or configured. In a normal system, more mass would have the more entropy, because entropy is an extensive variable. For a black hole, this is different (See the holographic principle.)

Since we can fully describe a black hole by its mass, charge, and spin, all its internal rearrangements go unnoticed. Black holes have maximal internal disorder and we can say that a black hole has maximal entropy.

How do we use this in Tao Philosophy?
