Thanks for the link ! But it says:
Quote:
...Edward Aloysius Murphy, Jr. (January 11, 1918 – July 17, 1990[1]) was an American aerospace engineer[ who worked on safety-critical systems. He is best known for his namesake Murphy's law, which is said to state, "Anything that can go wrong will go wrong."...
It seems that this has subsequently become confused. What is "said to state" (to my mind) is now the general definition of Sod's Law.
Sorry to correct a very esteemed contributor, but this is a simplification of a very complex issue. Murphy's Law is, as summarised "If it can go wrong, it will ..."
Sod's corollary states "When it goes wrong, it will be when the adverse effects are maximised"
These things should not be confused!
