Entropy chapter's concept guide is now UP.

The entire concept of entropy, at the end of chapter 14, is the target for physicists trying to understand

1. atmospheric physics like hurricanes,
2. quantum physics applied to communication and cryptography systems
3. black holes and other exotic astrophysical objects
4. many other phenomena

So this chapter is a good one to make a high priority target, intellectually speaking. That is, your wisdom will be very omnivorous if you can get a hold of the concept of entropy.

The concept guide is now available for chapter 14, the entropy chapter. So, have at it!!
