For example, science might study the flow of electrons in electrical conductors by using already-existing tools and knowledge. This new-found knowledge may then be used by engineers to create new tools and machines such as semiconductors, computers, and other forms of advanced technology. In this sense, scientists and engineers may both be considered technologists; the three fields are often considered as one for the purposes of research and reference. Engineering is the goal-oriented process of designing and making tools and systems to exploit natural phenomena for practical human means, often using results and techniques from science. Examples Of 'technology' In A Sentence Science is systematic knowledge of the physical or material world gained through observation and experimentation. Technologies are not usually exclusively products of science, because they have to satisfy requirements such as utility, usability, and safety. Philosophical debates have arisen over the use
