History of Engineering

Engineering has existed since ancient times when humans made inventions such as the pulley, lever, and wheel. Each of these inventions is important for the modern engineering, using basic mechanical principles to develop useful tools and objects.

The term engineering dates back to 1325, when an engineer (one who operates an engine) originally referred to Уa constructor of military engines.Ф The word УengineФ is of even older Latin origin, ingenium, meaning Уinvention.Ф Later, as the design of civilian structures such as bridges and buildings developed, the term civil engineering distinguished between the construction of such non-military projects and the older discipline of military engineering.

The first electrical engineer is William Gilbert, who was the author of the term "electricity".

Mechanical engineer Thomas Savery built the first steam engine in 1698. The development of this device gave rise to the industrial revolution and allowed the beginnings of mass production.

Electrical Engineering began with the experiments of Alessandro Volta in the 1800s, the experiments of Michael Faraday, George Ohm and others and the invention of the electric motor in 1872. The work of James Maxwell and Heinrich Hertz in the late 19th century gave rise to the field of Electronics. The later inventions of the vacuum tube and the transistor further accelerated the development of Electronics.

The inventions of Thomas Savery and the Scottish engineer James Watt gave rise to modern Mechanical Engineering. The development of specialized machines and their maintenance tools during the industrial revolution led to the rapid growth of Mechanical Engineering in Britain and abroad.

Chemical Engineering, like Mechanical Engineering, developed in the nineteenth century during the Industrial Revolution. The role of the chemical engineer was the design of chemical plants and processes.

In 1990, with the rise of computer technology, computer engineer Alan Emtage built the first search engine.
