Murphy's Law is a popular adage that states, "Anything that can go wrong, will go wrong." It suggests that if something has the potential to fail, it is likely to do so at the worst possible moment. This concept is often used to explain unexpected problems in various situations, from everyday tasks to complex projects. The law is named after Edward A. Murphy Jr., an American aerospace engineer, who coined the phrase in the late 1940s. It reflects a pessimistic view of life, emphasizing the importance of planning and preparation to mitigate potential failures.
