The shape of the modern world is all due to the advancement in science and technology, and the engineering field of science and technology is the major contributory factor towards achieving the scientific marvels of today.
The challenge of discovery, improvements and modifications to various machines, equipment etc., gives tremendous satisfaction and thrill to engineers. Engineering is no longer limited to the old-fashioned division of civil, mechanical and electrical engineering, but offers many other fields to specialize in.
Engineers work with structures, tools, machines, metals, chemicals etc. and use their alertness of mind and creativity to innovate and create new things or bring modifications to already existing machines.
Engineering is not so much one career, as an expertise, which opens doors into a vast range of jobs. Engineers probably have a wider choice of environment in which to work, and a greater variety of jobs, than is possible in any other profession.
This is because there is vast scope for engineers in advanced areas such as automobiles, thermal engineering, ultrasonic, vacuum technology, polymer technology, communication and computers, and many more areas. Interestingly, women who have gone into engineering are also doing well.
The purpose of engineering is to design and manufacture the hardware of life. Engineers have a hand in the creation of anything in use anywhere. They design, manufacture, repair, modify, and construct efficient and economical hardware of life. From simple bicycles to aeroplanes and rockets, from highways to dams, all of these are built by engineers.
