Murphy and Friends

(144 entries, updated July, 2020)

You might guess that a collection of 'laws' might focus on quotes from famous legal documents or court decisions, or even on humorous or outdated codes from US or international law. Nope. This is the 'Science' section - a collection of observed, imagined, or empirical laws of nature, social science and technology. More specifically, it is on observations of how these things don't always go the way we want them to.

The archetypal example is, of course, the original Murphy's Law, credited to Edward Murphy, that "if anything can go wrong, it will." Murphy was part of an Air Force team doing rocket-sled experiments in the late 1940's - the kind of experiment that requires lots of preparation, and has lots of steps - multiplying the chances for error.

Over the last half-century, Murphy's Law has spawned a wide range of correllaries and 'stepchildren'. This is a collection of those offspring, gleaned from an equally wide range of sources, including online discussion(usenet) groups during the early days of the internet, several 'authoritative' books on the subject, discussions while eating lunch on the stoop of Charlie's Fish Shack, and observations made during the Beatyville Wooly-Worm festival. Enjoy.
