Murphy's is a popular term often associated with the adage "Murphy's Law," which states that "anything that can go wrong, will go wrong." This concept highlights the unpredictability of life and the tendency for things to not go as planned. It is frequently referenced in various contexts, including engineering, project management, and everyday situations. The origin of Murphy's Law is attributed to Edward A. Murphy Jr., an American aerospace engineer, in the late 1940s. The phrase has since become a cultural reference, illustrating the humorous side of misfortune and the importance of preparation and contingency planning in both personal and professional settings.
