It is an excellent major to graduate in. Your doors of opportunity become widened and you may land a career anywhere in the engineering industry. You have the capabilities to understand the mechanics behind any type of product, device, or function. You will learn how physics is applied in real life and how your calculations will be considered in making ultimate decisions. You may very well get to use your degree outside the world of engineering and still apply it in teaching. You can teach any relevant field in Mathematics or Science. I know a friend that is a mechanical engineer and is working for a railroad company and another that is a mathematics instructor.
