Bret Underwood, Ph.D., Chair

Physics is the scientific study of the material universe at its most fundamental level: the mathematical description of space and time and the behavior of matter from the elementary particles to the universe as a whole. A physicist might study the inner workings of atoms and nuclei, the size and age of the universe, the behavior of high-temperature superconductors or the life cycles of stars.

Physicists use high-energy accelerators to search for quarks; they design new laser systems for applications in medicine and communications; they heat hydrogen gases to temperatures higher than the sun’s core in the attempt to develop nuclear fusion as an energy resource. From astrophysics to nuclear physics to optics and crystal structure, physics encompasses some of the most fundamental and exciting ideas ever considered.

Physics Major

The physics major offers a challenging program emphasizing a low student-faculty ratio and the opportunity to engage in independent research projects. There are two introductory course sequences, college physics and general physics; the general physics sequence incorporates calculus and is required for all majors and the minor.

Restrictions in Major and Minor

Restrictions for major in physics (B.A. degree), major in physics (B.S. degree), major in applied physics (B.S. degree), and the minor in physics: an average grade of C (2.00) is required for the three-course introductory sequence (Physics 153, 154, and 223) for them to be counted for a major or minor.

Also available is a major in applied physics, which includes a substantial selection of courses from engineering to provide a challenging and highly versatile degree. Applied physics can lead to research or advanced study in such areas as robotics—with application in space exploration or joint and limb prosthetics; growth of single-crystal metals, which would be thousands of times stronger than the best steels now available; mechanics of material failure, such as metal fatigue and fracture; turbulence in fluid flow; photovoltaic cell research for solar energy development; or applications of fluid flow and thermodynamics to the study of planetary atmospheres and ocean currents. While many applied physics graduates pursue professional careers in industry immediately after graduation from PLU, the program also provides excellent preparation for graduate study in nearly all fields of engineering.

Minor in Engineering & Industry
28 semester hours

The curriculum of the Engineering & Industry Minor consists of engineering courses, courses in business, economics, and ethics with a special emphasis on industry and/or an internship. Students choosing the minor will learn the basics of engineering design and team problem solving, will gain familiarity with industry, and will obtain valuable skills ensuring their success in the workplace or in graduate studies.

An Advisory Board comprised of engineering and science professionals associated with PLU will advise students in the Engineering Internship process for students who choose that option, will evaluate the quality of internships, and will consult with the program leaders on curriculum.

The Engineering & Industry Minor is ideal for all students who would benefit from in-depth exposure to engineering and industry. Typically students in Natural Sciences, Business, Economics or any students who have completed the introductory calculus-based physics sequence (PHYS 153/163, 154/164) would be a good fit for the minor. BS in Applied Physics students are NOT ALLOWED to add this minor, as it essentially is the minor aligned with the Applied Physics major.

  • ENGR 131
  • PHYS 153/163, 154/164 (calculus-based introductory physics plus laboratory)
  • 8 additional semester hours chosen from:
    • ENGR 240, 333, 334, 355
  • Plus: 8 additional semester hours chosen from:
    • ENGR 495 (credits vary depending on internship type and schedule)
    • Courses in business, economics, ethics, and history that introduce students to aspects of industry:
      • BUSA 201, 310, or 358
      • ECON 101 or 313
      • HIST 248, 254, 346, or 370
      • PHIL 125, 223, 225, 226, 248, or 327

All courses counted toward the minor must be completed with grades of C or higher.
