In this sense, I like the W. Brian Arthur's definition in his "The nature of technology":
"From all this it follows that science not only uses technology, it builds itself from technology. (...) Science builds itself from the instruments, methods, experiments, and conceptual constructions it uses. Science, after all, is a method: a method for understanding, for probing, for explaining. A method composed of many submethods. Stripped to its core structure, science is a form of technology."
