Murphy's Law

You probably have heard of Murphy's Law and it's likely that you have used the phrase or at least have encountered a situation where this adage (short statement expressing a general truth) or epigram (a brief saying or remark expressing an idea in a clever and amusing way) was used or should have been used.

"Anything that can go wrong will go wrong."

The origin of the phrase is totally unknown and it's likely that people were saying this is something close to it long before anyone attached a name to it. So the question here is whether there actually was a Murphy and if so why the name became attached to the adage?

According to one version, the origin stems from an attempt to use new measurement devices developed by Edward Murphy, an American aerospace engineer who worked on safety-critical systems. The phrase was coined in adverse reaction to something Murphy said when his devices failed to perform.

According to the book, A History of Murphy's Law by Nick Spark, this common bit of philosophy does have a military origin. But the "facts" still seem to be a bit hazy.

Murphy worked at Wright-Patterson Air Force Base on high-speed rocket sled experiments and that's supposed to be where and when the coining of Murphy's law happened.

Reportedly, Murphy was not happy with the commonplace interpretation of his law which he saw as more serious. Murphy regarded his law as an important principle of defensive design - one should always assume worst-case scenarios.

Though Murphy may have been serious, the law that carries his name has been used in many less-than-serious situations.
