| 词条 | Book:Observational cosmology - 30h course/Preface |
| 释义 | Like any standard science textbook or peer-reviewed article, none of the text, figures and formulae in this Wikipedia book should be believed without scepticism. Check the internal, mathematical and physical self-consistency of the material, check its consistency with the references in each chapter, check its consistency with recent open access summaries of observations and theory that you can find at http://arXiv.org. Feel free to participate in Wikipedia talk pages and to edit the article content yourself once you understand the material and the editorial principles sufficiently. |
