Engineers solve problems. They use chemistry, physics, and maths to determine the best way to create new things or improve a product. Engineers aim to design something that can solve economic, environmental, or social problems.

There are many different kinds of engineering. They often overlap with each other. The most prominent branches are civil, chemical, electrical, mechanical, and materials engineering. Civil engineering is one of the oldest fields of engineering. It is concerned with the safe design and construction of structures. Chemical engineers deal with the large-scale production of chemicals for industrial use. The duties of a chemical engineer overlap many fields. Electrical engineering focuses on electric power and all the systems and machines connected. Mechanical engineering encompasses the design, construction, and use of devices. Materials engineers develop new materials that result in products that make life easier, safer or more fun.
