Improve a random level 4 vital article in Physical sciences

Vital articles is a list of subjects for which Wikipedia should have corresponding high-quality articles. It serves as a centralized watchlist to track the status of Wikipedia's most essential articles. This is one of eleven Level 4 sub-lists of ten thousand articles and is currently under construction.

Articles in the Vital list have their assessments labelled as:

  • Featured articles
  • Former featured articles
  • A-class articles
  • Good articles
  • Delisted good articles
  • Failed good article nominees
  • B-class articles
  • C-class articles
  • Start-class articles
  • Stub-class articles
  • List-class articles
  • Unassessed articles

The progress bar is auto-updated via category count, and the symbols and article counts are updated daily by User:cewbot. Please read the FAQ before modifying the article list.

This list is tailored to the English-language Wikipedia. There is also a list of ten thousand articles considered vital to Wikipedias of all languages.

For more information on this list and the process for adding articles please see the Frequently Asked Questions (FAQ) page.
