Scientific research is built upon rigorous experimental design and logical reasoning, yet scientific discoveries do not always follow predetermined paths. Throughout the history of science, many important breakthroughs have arisen from unexpected observations and serendipitous discoveries. Drawing on Ohid Yaqub’s framework for classifying serendipity in research, this article uses classic examples—including cisplatin, rubber vulcanization, nitrous oxide anesthesia, and polytetrafluoroethylene—to illustrate different ways in which unexpected discoveries can occur. It further explores the common mechanisms underlying such discoveries: noticing anomalies, asking questions, connecting seemingly unrelated clues, communicating and collaborating across disciplines, and ultimately validating unexpected findings through experiments. The discovery of conducting polymers further demonstrates that serendipity alone does not lead to scientific breakthroughs; keen observation, sustained curiosity, accumulated knowledge, interdisciplinary exchange, and an open research environment are equally important. Although we cannot deliberately design serendipity, we can cultivate the ability to recognize and pursue the unexpected and create an environment in which unexpected findings are more likely to develop into scientific discoveries.
