Technology is the creation of new products and processes intended to improve our working efficiency, our chances for survival, our comfort level, and our quality of life. The goal of science is to develop widely accepted knowledge or ideas, which are intangible; by contrast, technology is concerned primarily with the development of substantial things.

In many cases, technology develops from known scientific laws and theories. Scientists invented the laser, for example, by applying knowledge about the internal structure of atoms. Applied scientific knowledge about chemistry and electronics has given us nylon, pesticides, washing powder, intelligent computers, mobile phones, digital cameras, pollution control devices, and countless other products. Applications of theories in nuclear physics led to nuclear bombs and nuclear power plants.
