What is light? How does a laser work? What is a black hole? What are the fundamental building blocks of the universe? Physics majors and Astrophysics majors study these and related questions to understand the physical world around us, from the very small to the very large. A physics student practices the experimental methods used to learn about this world and explores the mathematical techniques and theories developed to explain these physical phenomena. A Physics major or Astrophysics major serves as preparation for further work in physics, astrophysics, applied physics, other sciences, engineering, medical research, science teaching and writing, and other careers involving critical thinking, problem-solving, and insight into the fundamental principles of nature.
