'''Applied physics''' is the application of physics to solve scientific or engineering problems. It is usually considered a bridge or a connection between physics and engineering. "Applied" is distinguished from "pure" by a subtle combination of factors, such as the motivation and attitude of researchers and the nature of the relationship to the technology or science that may be affected by the work. Applied physics is rooted in the fundamental truths and basic concepts of the physical sciences but is concerned with the utilization of scientific principles in practical devices and systems and with the application of physics in other areas of science and high technology.<ref>{{cite web |title=General Information on Applied Physics |url=https://www.stanford.edu/dept/app-physics/general/ |publisher=Stanford Department of Applied Physics |archive-url=https://web.archive.org/web/20070307121331/http://www.stanford.edu/dept/app-physics/general/ |archive-date=7 March 2007}}</ref>
