engineering. In the U.S., this function is performed by DARPA. In contrast, technology development is a policy in which engineering, the application of science, is supported rather than basic science. The emphasis is usually given to projects that increase important strategic or commercial engineering knowledge. The most extreme success story is undoubtedly the Manhattan Project that developed nuclear weapons. Another remarkable success story was the "X-vehicle" studies that gave the US a lasting lead in aerospace technologies. These exemplify two disparate approaches: The Manhattan Project was huge, and spent freely on the most risky alternative approaches. The project members believed that failure would result in their enslavement or destruction by Nazi Germany. Each X-project built an aircraft whose only purpose was to develop a particular technology. The plan was to build a few cheap aircraft of each type, fly a test series, often to the destruction of an aircraft, and never design an aircraft for a practical mission. The only mission was technology development. A number of high-profile technology developments have failed. The US Space Shuttle failed to meet its cost or flight schedule goals. Most observers explain the project as over constrained: the cost goals too aggressive, the technology and mission too underpowered and undefined. The Japanese fifth generation computer systems project met every technological goal, but failed to produce commercially important artificial intelligence. Many observers believe that the Japanese tried to force engineering beyond available science by brute investment. Half the amount spent on basic research rather might have produced ten times the result. Utilitarian versus monumental science policy Utilitarian policies prioritize scientific projects that significantly reduce suffering for larger numbers of people. This approach would mainly consider the numbers of people that can be helped by a research policy. Research is more likely to be supported when it costs less and has greater benefits. Utilitarian research often pursues incremental improvements rather than dramatic advancements in knowledge, or break-through solutions, which are more commercially viable. In contrast, monumental science is a policy in which science is supported for the sake of a greater understanding of the universe, rather than for specific short-term practical goals. This designation covers both large projects, often with large facilities, and smaller research that does not have obvious practical applications and are often overlooked. While these projects may not always have obvious practical outcomes, they provide education of future scientists, and advancement of scientific
