Physics is the examination of matter, energy, and the interactions of forces which affect them. Through their explorations of the physical world, students in Trinity's Department of Physics and Astronomy strive to understand the laws affecting all natural phenomena, from subatomic particles to entire galaxies.

The department is primarily focused on undergraduate education, offering a major in physics and minors in both physics and astronomy. We provide students with access to state-of-the-art teaching and laboratory facilities and give them opportunities to work on meaningful research on the cutting edge of science.

Students may explore nanofabrication techniques and laser-based measurements or examine phenomena such as supernovas and quasars as they work on projects alongside our faculty. Those who complete the most intensive undergraduate research become co-authors - sometimes even lead authors - on articles in peer-reviewed journals.

Most graduates of Trinity's physics and astronomy programs pursue advanced degrees with the intention of becoming professional physicists or astronomers. However, some go on to teach or work in industry immediately after graduation.
