The first thing he did when he got home was to review what he had learned in class.
He summarized everything he learned mentally into a few rules that would guide his way. He even wrote them down in a notebook so that he could visit them later.
The first rule is that formation is a language. It is the language of nature and a means to speak with the world.
To him, this language is similar to the programming language of his previous world. They are extra similar in that both formation and programming languages are written languages.
The main difference is that formation is written with the world. Only in this way can communication be done with the world to make materials perform in a desired manner.
The second rule is that a formation can be as simple as a simple rule. At its simplest form, a formation is called a rune. This rune is the physical manifestation of a rule.
