Engineering is the regulation, art and career of obtaining and applying technical, scientific and mathematical knowledge to apply and design resources, configuration, machines, strategies, systems, and processes that securely realize a preferred purpose or innovations. Generally, engineering is the practical application of science, commerce or industry. Engineering is also somewhat different from science in that it must take into account the requirements and availability including costs, safety, presentation and limitations on assets.

It is regarded that the first engineer was ‘Imhotep’ builder of the famous Step Pyramid Saqqarah, Egypt in 2550 BC. Through out history the Wonders of the ancient, medieval and the modern world are exclusive engineering achievements. The speculation of engineering has existed since ancient times as human beings created fundamental inventions such as the pulley, lever, and wheel etc. Each of these inventions and discoveries are reliable with the modern description of engineering and utilizing basic mechanical principles to develop useful tools and objects.

Engineering, as similar to science is a broad study which is often classified into several branches. The main branches of engineering are Aerospace engineering, Chemical engineering, Civil engineering, Electrical engineering and Mechanical engineering. With the rapid development of science and technology many new fields are gaining importance and new branches are emerging, such as Computer Engineering, Software Engineering, Nanotechnology, Molecular engineering, etc.

With the growing popularity and increasing demand for this particular field of study and to fulfill the requirements of engineering students, engineering books and engineering handbook are largely available at the libraries and bookstores all over the world. These books provide all essential information and knowledge on different branches of engineering.
