These routes organize the existing ASD corpus by the question you want to answer. They do not create a new theory layer or change a result’s status. The order is an editorial reading suggestion, not a claim that each preceding page proves the next one.

## Start with your purpose

The [Introduction Path](/en/overview/learning-paths/introduction) begins with measurement and follows physical objects into fields, localized structures and detection. Its checkpoint is whether you can separate definitions, constitutive inputs and unresolved conclusions.

The [Researcher Path](/en/overview/learning-paths/researcher) begins with a pinned source and proceeds to a registered observable, an open task and a reproducible handoff. Its output is a reviewable research record, not a claim that an open problem has been solved.

The [Mathematical Path](/en/overview/learning-paths/mathematical) traces assumptions, intermediate equations, approximations and limits. It requires more mathematical preparation and returns to the original equation registry rather than introducing replacement formulas.

## Use the source as the authority

Each step contains a purpose, reading links, a checkpoint question and a concrete next action. Open the linked article to verify its definitions, version and current review conditions. If you cannot yet answer a checkpoint, leave it unchecked or move to a more suitable route. Reading progress is a local checklist, not a test score or a scientific endorsement.

Use the [Theory Map](/en/overview/theory-map) to inspect relationships, the [Terminology Database](/en/research/glossary) to clarify a term and the [Research Timeline](/en/research/timeline) to inspect recorded changes.
