combine harvester Agriculture & Agricultural Technology
Agriculture, the active production of useful plants or animals in ecosystems that have been created by people. Agriculture has often been conceptualized narrowly, in terms of specific combinations of activities and organisms—wet-rice production in Asia, wheat farming in Europe, cattle ranching in the Americas, and the like—but a more holistic perspective holds that humans are environmental engineers who disrupt terrestrial habitats in specific ways.

How is machine learning used in chemical synthesis? Computers
Have computers replaced dogs as man's best friend? They've certainly become an indispensable part of daily life for most people in our modern society. The first modern computers used analog systems, which were especially useful for solving problems and simulating dynamic systems in real time. By the 1960s, digital computers had largely replaced their analog counterparts. Later there was a similar transition from mainframe computers to personal computers. The advent of personal computers brought computers into the individual consumer's home for the first time. Rapid developments in computer and Internet technology powered an ever-expanding selection of handheld digital devices such as the Palm Pilot, BlackBerry, iPhone, and iPod. Computer chips were increasingly embedded in consumer devices of all sorts, including cars, cameras, kitchen appliances, toys, watches, and much more, reinforcing the interconnected nature of the world in which we now live.

Engineering, the application of science to the optimum conversion of the resources of nature to the uses of humankind. The field has been defined by the Engineers Council for Professional Development, in the United States, as the creative application of “scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behaviour under specific operating conditions; all as respects an intended function, economics of operation and safety to life and property.” The term engineering is sometimes more loosely defined, especially in Great Britain, as the manufacture or assembly of engines, machine tools, and machine parts.
