Engineering is the use of mathematical, scientific, and practical principles to invent, improve, maintain, and understand processes – like machines, structures, tools, and components. Engineering is an applied discipline, and so it is oriented towards delivering solutions to real-world problems. Given its Mathematical base, Engineers need to be highly numerate, combined with a knack for problem-solving and for dealing with complex, physical systems. Although physical processes are at the heart of Engineering disciplines, increasingly Engineers are considering the human element to the systems they model, particularly through sub-disciplines like ergonomics and sustainable engineering. Attempting to ensure their designs meet genuine aesthetic and commercial needs have brought Engineering into increasing dialogue with Business Studies, the Social Sciences, and the Arts. Engineering is a crucial part of the modern world, with many valuable skills to teach. Although many engineering students continue on with research, or enter professional employment as full-time engineers, others take their mathematical skills into sectors where such skills are in high demand, like Banking.
