Both science and technology are used interchangeably. They are strongly linked to one another, but are fundamentally different. Science is the theoretical base that enables technology to take flight. Technology becomes the practical applications of science. Consider Webster's definition of technology: "Technology includes all tools, machines, utensils, weapons, instruments, housing, clothing, communicating and transporting devices and the skills by which we produce and use them." Such an understanding displays how science is fundamentally different from technology as it gives birth to it.
The practicality that defines technology is what makes it fundamentally different from science. The idea of "tools, machines" or "utensils" helps to bring out the applicability of technology with which science is not necessarily concerned. Science is defined as "is the reasoned investigation or study of phenomena, aimed at discovering enduring principles among elements of the phenomenal world by employing formal techniques such as the scientific method." This investigatory and theoretical aspect that is highlighted in "enduring principle" discovery and "formal techniques such as the scientific method" differentiates science from technology. There is a "real world" application element that defines technology which is not as present in the scientific reasoning process.
Technology is a form of "applied science." It is viewed as “the practical applications of science.” American engineer Vannevar Bush suggested that one of the basic elements of the relationship between science and technology is how the former gives birth to the latter: "New products, new industries, and more jobs require continuous additions to knowledge of the laws of nature ... This essential new knowledge can be obtained only through basic scientific research." The fruit of scientific labor is technology. It is in this light where science and technology are fundamentally different. The realm of technology is geared towards real world application and execution. It takes science out of the laboratory and places it in the real world context. This differentiation is critical to understanding the premises of both.
