Serendipity refers to the occurrence of unexpected and fortunate discoveries. It often happens when someone is searching for something else entirely but stumbles upon a valuable or pleasant surprise. This concept is commonly associated with scientific discoveries, where researchers find new insights while investigating unrelated questions. The term originated from the Persian fairy tale "The Three Princes of Serendip," where the princes made discoveries by chance. In everyday life, serendipity can manifest in various ways, such as meeting a new friend in an unexpected place or finding a great deal while shopping.
