The following broad base definitions of  science and technology can be outline below


SCIENCE (from Latin scientia, meaning “knowledge”) is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.[1]

SCIENCE refers to the body of reliable knowledge itself, of the type that can be logically and rationally explained.

——-Aristotle 17th century



SCIENCE can be describe in a broad sense denoting reliable knowledge about a topic, in the same way it is still used in modern terms such as library science or political science

—–Galileo Galilei  17th century


SCIENCE more often refers to a way of pursuing knowledge, not only the knowledge itself. It is “often treated as synonymous with ‘natural and physical science’, and thus restricted to those branches of study that relate to the phenomena of the material universe and their laws, sometimes with implied exclusion of pure mathematics.

——–Johannes Keple 1764-1795


According to Webster’s New Collegiate Dictionary, the definition of science is “knowledge attained through study or practice,” or “knowledge covering general truths of the operation of general laws, esp. as obtained and tested through scientific method [and] concerned with the physical world.”

Technology is the making, modification, usage, and knowledge of tools, machines, techniques, crafts, systems, methods of organization, in order to solve a problem, improve a preexisting solution to a problem, achieve a goal or perform a specific function.

———-wikipeadia 1984



The use of tools, machines, materials, technigues and sources of power to make work easier and more productive. The cambrige Encyclopedia, David Crystal (Ed.), cambridge university press.


The fundamental application of scientific knowledge to the practical arts, resulting in improve













Technology is an overworked term. It once meant knowing how to do things—the practical arts or the study of the practical arts. But it has also come to mean innovations such as pencils, television, aspirin, microscopes, etc., that people use for specific purposes, and it refers to human activities such as agriculture or manufacturing and even to processes such as animal breeding or voting or war that change certain aspects of the world. Further, technology sometimes refers to the industrial and military institutions dedicated to producing and using inventions and know-how. In any of these senses, technology has economic, social, ethical, and aesthetic ramifications that depend on where it is used and on people’s attitudes toward its use.

Sorting out these issues is likely to occur over many years as students engage in design and technology activities. First, they must use different tools to do different things in science and to solve practical problems. Through design and technology projects, students can engage in problem-solving related to a wide range of real-world contexts. By undertaking design projects, students can encounter technology issues even though they cannot define technology. They should have their attention called to the use of tools and instruments in science and the use of practical knowledge to solve problems before the underlying concepts are understood.

On the whole, technology has been a powerful force in the development of civilization, all the more so as its link with science has been forged. Technology—like language, ritual, values, commerce, and the arts—is an intrinsic part of a cultural system and it both shapes and reflects the system’s values. In today’s world, technology is a complex social enterprise that includes not only research, design, and crafts but also finance, manufacturing, management, labor, marketing, and maintenance.

In the broadest sense, technology extends our abilities to change the world: to cut, shape, or put together materials; to move things from one place to another; to reach farther with our hands, voices, and senses. We use technology to try to change the world to suit us better. The changes may relate to survival needs such as food, shelter, or defense, or they may relate to human aspirations such as knowledge, art, or control. But the results of changing the world are often complicated and unpredictable. They can include unexpected benefits, unexpected costs, and unexpected risks—any of which may fall on different social groups at different times. Anticipating the effects of technology is therefore as important as advancing its capabilities.
