Quantum mechanics

The Wikipedia article on Quantum mechanics has been edited 8,126 times since it was created in 2001, by 4,012 distinct accounts and IP addresses. That averages about 326 recorded changes a year, or several every day, which puts it among the more actively maintained pages on the encyclopedia.

Within the revisions retrieved for this report, the ten busiest contributors account for about 55% of the changes, with the rest spread across a long tail of occasional editors. That is a fairly typical mix of regular maintainers and passing corrections. In the same window, about 7% of the retrieved revisions came from bot accounts, which handle routine work such as link repair and reference formatting, and only about 2% came from unregistered IP editors, which often indicates the page is protected against anonymous editing.

Within the retrieved window, 2020 carries the most recorded activity, with 125 changes. 10 of those revisions fall in the last 90 days. The most recent recorded edit was 47 days ago.

Readership has been broadly stable across the last two years of pageview data. The clearest peak in that record falls in April 2026. Traffic spikes and editing spikes often line up, but the revision record alone cannot tell you which one caused the other, or whether an outside event drove both.

This report is built from the 500 most recent revisions retrieved from Wikipedia, about 6% of the 8,126 recorded edits. Figures drawn from that window describe the window only, and the report cannot establish why a change was made or whether it was correct.
