Engineers apply the principles of science and mathematics to develop economical solutions to technical problems. Their work is the link between scientific discoveries and the commercial applications that meet societal and consumer needs. They also use their imagination and analytical skills to invent, design, and build things that matter. They are team players with independent minds who turn ideas into reality. Many become licensed professional engineers in order to better protect the health, safety, and welfare of the public.  By dreaming up creative and practical solutions, engineers are changing the world all the time.

Engineering has been called the “invisible” or “stealth” profession. Everything around us and that we use every day has been engineered in some way, yet we may not see the engineers behind the scenes or know much about engineering. Engineering is not part of our grade school education. Many engineers whose work affects the public become licensed. The engineering field is as varied as engineers themselves. Engineers can design and build superstructures or delicate medical instruments. Engineers are exploring for energy and for new worlds in space. They are designing the environmental controls for an art museum or directing global sales of today’s hottest cars and computers. The engineering is commonly divided into four major disciplines, civil, mechanical, electrical and chemical engineering. In every discipline, there are more minor or specialized engineering fields that have been used in modern world. However, it is easier for the author to categorize the major achievements and their big impact of engineering to the world with concern of different major of engineering.


Engineering has existed since ancient times as humans devised fundamental inventions such as the pulley, lever, and wheel. Each of these inventions is consistent with the modern definition of engineering, exploiting basic mechanical principles to develop useful tools and objects. First and foremost, the question is who invented the wheel? There are too many claims on the invention of wheel, some people will say the Mesopotamians were the right inventor, and some people claim Egyptian invented it first and it also could be other ancient civilization. The truth is, no one can prove evidently on it, but the benefit of the wheel is huge until now. More people advanced, more advance the technology and engineering were. Look at the 7 Ancient Wonders; some people would like to appreciate from the art and culture point of view, but as an engineer, the author look at them as the symbolic and iconic of tremendous engineering achievement on that time. Some of the engineering mechanisms in them are still mysterious pieces of work until now. For example, the earliest civil engineer known by name is Imhotep. As one of the officials of the Pharaoh, Djosèr, he probably designed and supervised the construction of the Pyramid of Djoser (the Step Pyramid) at Saqqara in Egypt around 2630-2611 BC. He may also have been responsible for the first known use of columns in architecture.

Chemical engineers apply the principles of chemistry to solve problems involving the production or use of chemicals and other products. They design equipment and processes for large-scale chemical manufacturing, plan and test methods of manufacturing products and treating by products, and supervise production. Chemical engineers also work in a variety of manufacturing industries other than chemical manufacturing, such as those producing energy, electronics, food, clothing, and paper. In addition, they work in healthcare, biotechnology, and business services. Chemical engineers apply principles of physics, mathematics, and mechanical and electrical engineering, as well as chemistry. Some may...
