I have been trying to point out that in our lives chance may have an astonishing influence and, if I may offer advice to the young laboratory worker, it would be this - never to neglect an extraordinary appearance or happening.

The quote by Alexander Fleming, "I have been trying to point out that in our lives chance may have an astonishing influence and, if I may offer advice to the young laboratory worker, it would be this - never to neglect an extraordinary appearance or happening," highlights the importance of being open to the unexpected. Fleming emphasizes that chance events, or what might seem like random occurrences, can have a significant impact on discoveries and breakthroughs, particularly in scientific work. His advice to young scientists is to pay attention to unusual or unexplained phenomena, as they can lead to important insights or innovations.

Fleming is referring to his own famous experience of discovering penicillin. In 1928, while working in his laboratory, he noticed that a mold had killed the bacteria in a petri dish. This chance observation led to one of the most important medical breakthroughs in history. Fleming's quote suggests that in science, and in life, unexpected or seemingly trivial moments can sometimes reveal the most significant opportunities for discovery.

The origin of this quote is rooted in Fleming's career as a scientist and his humility about the role that serendipity played in his work. While he was a skilled and dedicated researcher, his discovery of penicillin is often considered an example of how a random event or unexpected occurrence can lead to groundbreaking results. His advice reflects his belief that curiosity and attentiveness to the unusual are key to making such discoveries.

Ultimately, Fleming's quote serves as a reminder of the importance of openness to the unexpected in both scientific research and daily life. By staying attentive to seemingly minor or extraordinary appearances, one may uncover new paths to knowledge and understanding. It encourages young researchers and others to embrace serendipity and trust that even the most random events can have profound effects.
