What is Technology?It is the innovation, change, or modification of the natural environment in order to satisfy perceived human wants and needs. (Standards for Technological Literacy, ITEA, 2000)The goal of technology is to make modifications in the world to meet human needs. (National Science Education Standards, NRC, 1996)

What is Technology ? (Continued)

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. (Benchmarks for Science Literacy, AAAS, 1993)Technology is the process by which humans modify nature to meet their needs and wants. (Technically Speaking: Why All Americans Need to Know More About Technology, NAE/NRC,2002)

Updated Definition of Technology

• Technology is the modification of the natural world to meet to human wants and needs. It helps us to improve our health; to grow and processed food and fiber better; to harness and use energy more efficiently; to communicate more effectively; to process data faster and accurately; to move people and things easier; to make products to enhance our lives; and to build structures that provide shelter and comfort.

What is Engineering?“Design under constraint. Engineers design solutions to problems. However there are a set of constraints that we have to satisfy -- size, weight, reliability, safety, economic factors, environmental impact, manufacturability, and a whole list of “--bilities” (Wulf)the profession in which a knowledge of the mathematical and natural sciences gained by study, experience, and practices are applied with judgments to develop ways to utilize economically the materials and forces of nature for the benefit of mankind. (Accreditation Board for Engineering and Technology (ABET, 2002)
