I see a little different relationship between the three. Engineering uses discoveries in Science to produce Technology.

Hello pvhramani,

The three are inter-dependent.

Scientists use Technology

Engineers use Technology

Technologists develop better Science

Engineers use that better Science

And so it goes.........

For each of the above, an understanding of a wide area of knowledge is needed.

Kind Regard.....

Accumulation from the internet ( The world book)

To claim something is SCIENTIFIC it should be undeniable. For example: To state simply, deniability means that it should be possible to set up an experiment that can possibly refute the scientific claim. For example, taking Newton's example, it should be possible to set up and experiment that can possibly prove that action and reaction are not always equal. One such simple 'experiment' would be putting your pen on the tabletop. If action-reaction were not equal-opposite, the pen would fall through the table. But is does not happen.

Technology on the other hand, is a product of engineering and science, the study of the natural world. Where science has two parts: (1) a body of knowledge that has been accumulated over time and (2) a process-scientific inquiry-that generates knowledge about the natural world. Engineering, too, consists of a body of knowledge-in this case knowledge of the design and creation of human-made products-and a process for solving problems. Science aims to understand the "why" and "how" of nature, engineering seeks to shape the natural world to meet human needs and wants. Engineering, therefore, could be called "design under constraint," with science-the laws of nature-being one of a number of limiting factors engineers must take into account. Other constraints include cost, reliability, safety, environmental impact, ease of use, available human and material resources, manufacturability, government regulations, laws, and even politics. In short, technology necessarily involves science and engineering.
