Partial coverage

This report displays 500 retrieved recent revisions — about 6% of the reported 8,122 edits. It cannot establish why a change was made, whether it is correct, or what happened outside this window.

Retrieved for this report: Aug 22, 2026, 1:33 PM UTC. Totals and pageviews are source-provided; the activity signal and section list are derived from the retrieved window.

What this edit history shows

The Wikipedia article on Quantum mechanics has been edited 8,122 times since it was created in 2001, by 4,011 distinct accounts and IP addresses. That averages about 328 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 8% 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 129 changes. 29 of those revisions fall in the last 90 days. The most recent recorded edit was 17 days ago.

Readership is cooling: the last three months of pageviews run about 31% below the preceding period. 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 8,122 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. For older revisions, talk-page discussion and full context, follow the source history on Wikipedia.

RobertGsuggest the opening sentence could state that its interpretation is problematic, rather than referring to "its unusual characteristics" as if the new reader already knows all about them; and "unusual" feels vague without explanation of what "usual" would mean -- I suggest using Feynman's words from the ref instead

SrlefflerWe are missing a disambiguation hatnote to the book with the same name. If there is more than one ambiguous article we could create a dab page, but I only found the one so far.
