Engineering involves designing, developing and testing of products. This is accomplished by using science, mathematics, physics and technology. There are numerous types of engineering jobs available and they fall into varying categories. Aerospace engineers develop spacecraft, missiles and aircraft that can be used for travel as well as for the transport of goods from one place to another. They will often specialize in one type of vehicle like passenger planes, rockets or helicopters. They can also become involved with deep-diving vessels that are utilized for research in the ocean. Or they can develop and maintain high-speed trains that float above the tracks. This discipline includes aeronautical specialization, which is focused on aircraft, and astronautical specialization which is focused on spacecraft. Chemical engineers design, construct and operate machines that carry out chemical reactions to be able to solve practical problems in addition to to make useful products. They apply their knowledge of chemistry to the other disciplines like math, physics and economics. They assist in the introduction of polymers, dyes, fertilizers, plastics and drugs etc. Civil engineers focus on the design, construction and the maintenance of public works. This includes areas like transportation, government buildings, airports, water treatment and train stations. They are employed by private companies or municipalities. Electrical engineers have many job options although most of them design products that are powered by electricity or products which produce electricity. These individuals will start by finding out the objective of the product. They will calculate the wiring and circuitry and build a prototype on which to run tests. They will also investigate the reasons for breakdowns in certain products. Metallurgical engineers are normally employed in the steel and iron industry. They will be involved in the processing of raw materials or in the manufacture of machinery or other products that are made of metal. Physical metallurgy focuses on the physical structures and properties of alloys and metals. Extractive metallurgy focuses on separating ore from metal. In conclusion, as a society we need more young people to study maths and science to ensure that we develop the many engineers we need in all areas of industry. The world would have been a very poor place without engineers, imagine a world without roads or bridges; without cars or aeroplanes; without ships or skyscrapers. Almost every piece of modern and not so modern technology relies on engineering skills to not only create the products to begin with, but also to develop and improve them further.
