The Main-Sequence: The star now settles down to a long period of stability while the hydrogen at its centre is converted into helium with the release of an enormous amount of energy. This stage is called the main-sequence stage, a reference to the classical Hertsprung-Russell diagram (see the Figure below). Most stars lie in a well defined band in the diagram, and the only parameter that determines where in the band they lie is the star's mass.
Becoming a Professional Engineer (PE) A Professional Engineer (PE) is an engineer certified by a state board of registration to practice engineering. The PE license is the engineering profession's highest standard of competence, a symbol of achievement and assurance of quality. The College of Engineering believes that professional registration is an important goal for engineering graduates. Passing the FE Exam is the first step toward that goal.
Licensure and Certification. Licensure as a Professional Engineer (PE) is often required; some may be able to work under the supervision of a PE. Key Skills. Good mathematical ability, skills in decision making, problem solving, critical thinking, verbal communication and operations analysis.ecoming an engineer begins with graduating from a bachelor's degree program that is ABET (Accreditation Board for Engineering and Technology) accredited. This will require meeting science and math qualifications.
