when discussing atoms, language could serve as nothing more than a kind of poetry.

Globally scoped data is fundamentally in conflict with the object-oriented philosophy of endowing objects with abilities and then getting things done by sending requests to those objects. Some Ruby programmers work for years and never use a single global variable (except perhaps a few of the built-in ones).

Conveniently, Ruby objects come with their own storage and retrieval mechanisms for values: instance variables.

Composite/Atomic – entities are often grouped together. For example, bundles of product offerings, network elements composed of physical and logical resources.
