Science includes various Branches, One of them is engineering, and likewise other Branches of science, engineering science is broad subject area which is often disordered down into various sub-disciplines. As other branches of science having wide scope, engineering science also have huge scope. These disciplines bear on themselves with differing areas of engineering science work all disciplines. Although initially an engineer will usually be trained in a specific discipline, throughout an engineer's career the engineer may become multi-disciplined, having worked in several of the outlined areas. Basically engineering science part in to four chief branches. All four branches are really large. There is wide scope in all four branches. Know more about all four branches in details as fallows.
• Civil engineering - Branch of science which deals with the dams or bridges construction is called as Civil engineering .This engineering is the branch of engineering concerned with the blueprint and construction of such public works as dams or bridges. Civil engineering is a professional engineering science discipline that deals with the blueprint, building and maintenance of the physical and naturally built environment, including works such as bridges, roadstead, canals, dams and buildings.
• Mechanical engineering - Mechanical engineering is the branch of engineering that deals with the blueprint and construction and operation of machinery. This branch mainly deals with the machinery. Mechanical Engineering science is an engineering discipline that was highly-developed from the application of principles from physics and materials science. This branch completely derived from physical science and material science.
•Chemical engineering - Chemical engineering is the branch of engineering science that is deals with the blueprint and construction and operation of the plants and machinery used in industrial chemical processes. this branch of engineering that is deals with the blueprint and construction and operation of the plants and machinery used in industrial chemical. This branch mainly focused on various chemical processes.
• Electrical engineering - Electrical engineering science is the branch of engineering that deals with the engineering science of electricity, especially the blueprint and application of circuitry and equipment for power generation and distribution, machine control, and communications. this branch deals with the various designs, construction and uses of electric system. Apart from these four branches, engineering science have various other branches, other branches includes naval engineering and mining engineering.
Modern fields sometimes included as major branches include industrial, aerospace, architectural, and nuclear engineering. New specialties sometimes combine with the traditional fields and form fresh branches. A fresh or rising area of application program will commonly be defined temporarily as a permutation or subset of existing disciplines; there is often gray area as to when a given sub-field becomes large and/or prominent enough to warrant categorization as a fresh "branch." One key indicator of such growth is when major universities start establishing departments and programs in the fresh field. For each of these fields there exists considerable overlap, especially in the areas of the application of sciences to their disciplines such as physics, chemistry and math’s. Methodology for Engineering Engineers apply the sciences of physics and mathematics to find desirable solutions to problems or to make improvements to the condition quo. More than ever, engineers are now needed to have knowledge of relevant sciences for their blueprint projects; as a result, they keep on learning fresh material throughout their career. If multiple choices exist, engineers weigh different blueprint choices on their merits and choose the solution that best matches the requirements. The all-important and singular task of the engineer is to identify, empathies, and interpret the constraints on a blueprint in order to produce a successful result. It is usually not enough to build a technically successful product; it must also meet further requirements. Constraints may include available resources, physical, imaginative or technical limitations, flexibility for future modifications and additions, and other factors, such as requirements for cost, safety, marketability, predictability, and serviceability. By understanding the constraints, engineers derive specifications for the limits within which a viable object or system may be produced and operated.
