EXAMINE. CHALLENGE. EXTEND.

Continue the research.

Independent derivations, mathematical criticism, numerical reproduction and experimental design are welcome. Leave a contribution others can check.

Start with a question that can be located

A formula correction, an independent calculation or a question about an instrument response is a useful starting point. A complete paper or prior agreement with ASD is not required. Identify a source page, equation or task and explain what you checked and why the result merits discussion.

Read the relevant source, complete a bounded check, preserve its steps, then discuss it by email: jyliubj@gmail.com.

The four approaches below can all produce reviewable material. You send your own draft. Adoption, attribution and public citation are determined through human discussion and review. Receipt does not imply acceptance, and emails do not automatically enter the manuscript or public knowledge base.

REPRODUCE

Recalculate

Check inputs, steps and limits to reproduce a result.

CRITIQUE

Critique

Identify a specific mathematical issue, hidden assumption or experimental constraint.

EXTEND

Extend

Develop equations, solutions and numerical methods for open problems.

EXPERIMENT

Design a test

Build measurable signals, error budgets and discriminating designs.
