Scientific discovery refers to the process of uncovering new knowledge about the natural world through observation, experimentation, and analysis. This can involve identifying new phenomena, developing theories, or creating technologies that enhance our understanding of various subjects, such as biology, physics, or chemistry. Throughout history, many significant scientific discoveries have transformed our lives. For example, the discovery of penicillin by Alexander Fleming in 1928 revolutionized medicine by introducing antibiotics, which have saved countless lives. Such discoveries often build on previous knowledge, leading to further advancements and a deeper understanding of complex systems.
