基礎研究
Scientific research can be labeled as either basic or applied research. Basic research is the search for knowledge and applied research is the search for solutions to practical problems using this knowledge. Although some scientific research is applied research into specific problems, a great deal of our understanding comes from the curiosity-driven undertaking of basic research. This leads to options for technological advances that were not planned or sometimes even imaginable. This point was made by Michael Faraday when allegedly in response to the question "what is the of basic research?" he responded: "Sir, what is the use of a new-born child?". For example, research into the effects of red light on the human eye's rod cells did not seem to have any practical purpose; eventually, the discovery that our night vision is not troubled by red light would lead search and rescue teams (among others) to adopt red light in the cockpits of jets and helicopters. Finally, even basic research can take unexpected turns, and there is some sense in which the scientific method is built to harness luck.
