Engineering is the application of math and science to create something of value from our natural resources. If we look carefully we would find that everything is engineering i.e. from transistors to cell phones, from cycles to rockets, from fans to microwaves, from roads to dams, from computer chips to artificial limbs and the list is unending. Theodore Von Karman, an aerospace engineer, put it nicely when he said, Scientists discover the world that exists; engineers create the world that never was. It is a branch of science, which deals with innovation. It helps in progress of new methods of solutions and analysis for open-ended, complex and unique problems.
Engineering is the application of mathematics, as well as scientific, economic, social, and practical knowledge in order to invent, innovate, design, build, maintain, research, and improve structures, machines, tools, systems, components, materials, processes, solutions, and organizations.
The discipline of engineering is extremely broad and encompasses a range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied science, technology and types of application.
