Editing Murphy's law (section)

== Variations (corollaries) of the law ==
From its initial public announcement, Murphy's law quickly spread to various technical cultures connected to [[aerospace engineering]].<ref>{{cite web |url=http://www.catb.org/jargon/html/M/Murphys-Law.html |title=Murphy's Law |work=[[Jargon File]] |access-date=2012-04-19 |archive-url=https://web.archive.org/web/20120214092035/http://catb.org/jargon/html/M/Murphys-Law.html |archive-date=2012-02-14 |url-status=dead }}</ref> Before long, variations of the law applied to different topics and subjects had passed into the public imagination, changing over time. Arthur Bloch compiled a number of books of corollaries to Murphy's law and variations thereof, the first being ''Murphy's Law, and Other Reasons Why Things Go WRONG'', which received several follow-ups and reprints.<ref name=":0" />

[[Yhprum's law]] is an optimistic reversal of Murphy's law, stating that "anything that can go right will go right". Its name directly references this, being "Murphy" in reverse.

Management consultant [[Peter Drucker]] formulated "Drucker's law" in dealing with complexity of management: "If one thing goes wrong, everything else will, and at the same time."<ref>Drucker, Peter F. ''Management, Tasks, Responsibilities, and Practices'', p. 681</ref>

"Mrs. Murphy's law" is a corollary of Murphy's law, which states that "Anything that can go wrong will go wrong while Mr. Murphy is out of town."<ref>{{citation |title=Murphy's Law 2000 |page=4 |author=Arthur Bloch |year=1998}}</ref><ref>{{citation |title=Mysteries of life and the universe |page=171 |author=William H.

The term is sometimes used to describe concise, ironic, humorous [[rules of thumb]] that often do not share a relation to the original law or Edward Murphy himself, but still posit him as a relevant expert in the law's subject. Examples of these "Murphy's laws" include those for [[military tactics]], [[technology]], [[Romance (love)|romance]], [[social relation]]s, [[research]], and [[business]].<ref>{{Cite web |title=Cheap Thoughts |url=https://www.angelo.edu/faculty/kboudrea/cheap/cheap3_murphy.htm |access-date=2023-08-03 |website=www.angelo.edu |archive-date=2023-08-03 |archive-url=https://web.archive.org/web/20230803191705/https://www.angelo.edu/faculty/kboudrea/cheap/cheap3_murphy.htm |url-status=dead }}</ref><ref>{{Cite web |title=Murphy's laws |url=https://www.cs.cmu.edu/~fgandon/miscellaneous/murphy/ |access-date=2023-08-03 |website=www.cs.cmu.edu}}</ref><ref>{{Cite web |title=Murphy's Laws of Combat Operations |url=https://meyerweb.com/other/humor/mcom.html |access-date=2023-08-03 |website=meyerweb.com}}</ref>
