Technology can be viewed as an activity that forms or changes culture.[11] Additionally, technology is the application of math, science, and the arts for the benefit of life as it is known. A modern example is the rise of communication technology, which has lessened barriers to human interaction and, as a result, has helped spawn new subcultures; the rise of cyberculture has, at its basis, the development of the Internet and the computer.[12] Not all technology enhances culture in a creative way; technology can also help facilitate political oppression and war via tools such as guns.

Order No. DE93012225 DOE-HDBK-1017 2-93 MATERIAL SCIENCE ABSTRACT The Material Science Handbook was developed to assist nuclear facility operating contractors in providing operators maintenance personnel and the technical staff with the necessary fundamentals training to ensure a basic understanding of the structure and properties of metals. The handbook includes information on the structure and properties of metals stress mechanisms in metals failure modes and the characteristics of metals that are commonly used in DOE nuclear facilities. This information will provide personnel with a foundation for understanding the properties of facility materials and the way these properties can impose limitations on the operation of equipment and systems.
