What is Engineering?
Engineering is a career in which the knowledge of mathematical and natural sciences is applied with judgement to develop ways to utilize economically the materials and forces of nature for the advantage of society. Mechanical engineering is one of the known engineering discipline we are seeing today. In fact, this discipline is the widest and oldest branch of engineering. This engineering field requires an understanding of core concepts including mechanics, thermodynamics, materials science, structural analysis, and electricity. This discipline work on power-producing machines such as turbines, electric generators, internal combustion. Mechanical engineers also work on power-using machines such as elevators, escalators, air-conditioning equipment and so on. They also work through analysis, design, and synthesis as those are some of the key functions in this field. Other major engineering field that exists today is electrical engineering. Electrical engineers work through research, design, develop, test, and oversee the development electronic systems and manufacture the electrical and electronic devices. Technologies developed by electrical engineers have benefit our lives in many ways and make our world a better place to live. For instance, they created the cell phones, lasers, GPS, portable music players, and of course, satellite TV. Electrical engineers also contribute to other fields as well. In medical field, they develop new pacemakers for ailing hearts, ultrasonic diagnostic devices for detection of tumors and NMR machines. In the aerospace field, they provide secure and reliable communication to expeditions in remote and dangerous locations and to astronauts in space. They contributed in countless ways and make our lives more effective, efficient, productive, and increases our standard of living.
