Engineering

Engineering is the application of science to build structures, devices, materials, etc. It is arguably the largest feild, with carpenters, masons, construction wokers, architects and programmers all being engineers.

Mechanical Engineering
Engineering built primarily upon the use of simple machine to reduce force. EX: Water Wheel. This is one on the earliest forms of engineering, with Materials Engineering being the first. Mechanical engineering is by no means ancient, as it is still one of the most important fields to this day. All of our vehicular transports along with all moving parts in any machine rely on mechanical engineering.

Materials Engineering
The first form of engineering ever developed (Clay to make bricks, etc.). Formed as early as the ancient civilizations first buildings. Some "Devices" such as pyramids are still left today. As the field progressed, more advancements were made, such a smelting and the creation of alloys. Brass was one of the early new materials and more recently steel and vulcanized rubber were created. The space program led to a plethora of new materials such as heat absorbing tiles and better fabrics.

Electrical Engineering
Engineering involving solid state circuitry and electronics. One of the more recent forms of engineering developed with its first real use by Thomas Edison. The electrical field took off in the 20th century when household electronics became common. While electrical engineering was still a succesful field, it did not really become recognised until the advent of computer technology. When microchips came into the field, the sub-field of software engineering was also born. Software engineering involves programing comands in semi-conductive silicon via a developement environment and computer. It uses the basic binary system to form incredibly complex programs.
