The physics major at Saint Louis University provides a foundation for all the natural sciences and engineering disciplines. Physics has brought many revolutionary ideas such as relativity, quantum mechanics, and the Big Bang Theory, profoundly altering how humankind views the universe.<br><br>Physicists have made many breakthrough discoveries. The invention of the transistor by physicists has made the modern computer possible, while the development of lasers has led to diverse applications ranging from supermarket scanners to laser surgery. Physicists are versatile problem solvers and excel in many technical fields.<br><br>Training in physics leads to a broad-based understanding of natural phenomena, analytical and computer skills, experience with electronics and the operation of sophisticated equipment, an understanding of measurements and their limitations, and the ability to formulate and solve complex technical problems. <br>Graduates with a bachelor's degree in physics enter various careers that depend on the technical skills gained in college. Alumni are employed in product development and quality control in large industries such as RCA, Boeing and Lockheed-Martin. Alumni are computer specialists at Anheuser-Busch and other companies. Some are now involved in the marketing of technical products, while others are in management positions. A few graduates have entered military careers. Students frequently earn double majors, combining physics with mathematics, computer science or chemistry.
