An engineer is a professional practitioner of engineering, concerned with applying scientific knowledge, mathematics and ingenuity to develop solutions for technical problems. Engineers design materials, structures, machines and systems while considering the limitations imposed by practicality, safety and cost.The word engineer is derived from the Latin root ingenium, meaning "cleverness".
Engineers are grounded in applied sciences and are distinguished from scientists who perform research and artists who create with a focus on aesthetics.The work of engineers forms the link between scientific discoveries and the applications that meet the needs of society.
