Science helps drive technology, as it addresses questions that demand more sophisticated instruments and provides principles for better instrumentation and technique. Technology is essential to science, because it provides instruments and techniques that enable observations of objects and phenomena that are otherwise unobservable due to factors such as quantity, distance, location, size, and speed. Technology also provides tools for investigations, inquiry, and analysis. Perfectly designed solutions do not exist. All technological solutions have trade-offs, such as safety, cost, efficiency, and appearance.
Engineers often build in back-up systems to provide safety.
Risk is part of living in a highly technological world. Reducing risk often results in new technology. Technological designs have constraints. Technological solutions have intended benefits and unintended consequences. Some consequences can be predicted, others cannot.
