Chemical engineering is unique in that it requires a thorough understanding of chemistry as well as physics and mathematics. Chemical engineers use these scientific principles to design and operate plants which produce materials that undergo chemical changes.
Civil Engineering is the oldest branch of the engineering profession. It is concerned with the design and construction of shelters and infrastructure and environmental systems that improve quality of life.
Mechanical engineering is one of the broadest of all engineering discipines. Although its primary purpose could be summarized as "creating and improving machines to benefit mankind," this fundamental task engages the mechanical engineer in a vast array of fascinating specialty areas.
