Who is an Engineer??????????

An engineer is a professional practitioner of engineering, concerned with applying scientific knowledge, mathematics and ingenuity to design and develop solutions for technological systems 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 whose focus is most often research, and artists who create with a focus on aesthetics
