This is nothing less than a mathematical field guide to inanimate nature.

Science has taught us that what we see and touch is not what is really there.

Entropy is not about speeds or positions of particles, the way temperature and pressure and volume are, but about our lack of information.

Numbers instill a feeling for the lie of the land, and furnish grist for the mathematical mill that is the physicist's principal tool.

The smell of subjectivity clings to the mechanical definition of complexity as stubbornly as it sticks to the definition of information.
