“In general, entropy refers to the notion that

everything in the universe eventually moves from a state

of order, certainty, and fewer organizational possibilities

(from the atomic perspective) to one of disorder,

randomness, and greater organizational possibilities.

Entropy is the measurement of that change. To facilitate

the conceptualization of entropy in this book, we will

associate the term with order (in the case of low entropy)

and disorder (in the case of high entropy), conceding

to the scientific community that this is a practical

oversimplification of a highly complex concept.

As discussed earlier, a common example of entropy is

that of ice melting into water: from a cold to an ambient

temperature, from solid to free form, from order to

disorder: displaying throughout this transformation

an increase in entropy.”
