Humankind has long striven to improve its living conditions through the development of tools, instruments, and transportation and communications systems, all with the goal of making our lives easier, more productive and—why not—more fun, too! Thanks to human curiosity and technological research, many significant inventions have been made throughout history that in turn made a difference in our daily lives.

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.
Cars & Other Vehicles
Automobile, byname auto, also called motorcar or car, a usually four-wheeled vehicle designed primarily for passenger transportation and commonly propelled by an internal-combustion engine using a volatile fuel.
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, though analog computers continued to be used for aircraft and spaceflight simulation. Later there was a similar transition from mainframe computers—large machines that were typically shared by multiple people within one organization—to personal computers, which were much more manageable in size and usability. 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.
Industry, a group of productive enterprises or organizations that produce or supply goods, services, or sources of income. In economics, industries are customarily classified as primary, secondary, and tertiary; secondary industries are further classified as heavy and light.
Invention, the act of bringing ideas or objects together in a novel way to create something that did not exist before.
The Web & Communication
Telecommunication, science and practice of transmitting information by electromagnetic means. Modern telecommunication centres on the problems involved in transmitting large volumes of information over long distances without damaging loss due to noise and interference. The basic components of a modern digital telecommunications system must be capable of transmitting voice, data, radio, and television signals. Digital transmission is employed in order to achieve high reliability and because the cost of digital switching systems is much lower than the cost of analog systems. In order to use digital transmission, however, the analog signals that make up most voice, radio, and television communication must be subjected to a process of analog-to-digital conversion.
