What is an Engineer?
An engineer uses science, technology and math to solve problems. We can see engineering everywhere in the world around us, improving the ways we work, travel, communicate, stay healthy, and entertain.
Today, the field of engineering offers more career choices than any other discipline! In the past, there were four major engineering branches: mechanical, chemical, civil and electrical. Today, the number of available engineering degrees are vast. There are now six major branches of engineering: mechanical, chemical, civil, electrical, management, and geotechnical, and under each branch there are hundreds of different subcategories.
