Mechanical engineers specialize in converting energy into a useful form. Examples are designing automobile engines, generating electrical power, and designing refrigeration systems. Civil engineers are the builders of the engineering world. They design and construct buildings and facilities such as dams, bridges, and tunnels. Other common specialties are bioengineering, chemical, aeronautical, environmental, agricultural, materials, nuclear, petroleum and natural gas, and mining engineering.
Engineering is a very large field.
There are more engineers employed than chemists, geologists, biologists, medical scientists, and mathematicians combined. Over eight percent of engineers of all ages are women, but the percentage of graduating engineers who are women is much higher. Because engineers typically provide services that relate directly to producing a product or service that can be sold, they are usually in high demand in the job market. Engineers can normally find employment directly in the field for which they are trained. Engineering can be a challenging and rewarding career offering both personal satisfaction and material rewards.
