# Physics

Physics concerns itself with the laws governing energy and the structure of matter. The study of Physics will develop effective problem-solving skills, which can be applied advantageously to many other disciplines, especially those where quantitative methods are important. Undergraduate training emphasizes the basics and is usually very general. Specialization mostly takes place in graduate studies. A significant fraction of the Physics Bachelors at UNO - about one-third - go on to graduate school with the goal of becoming research scientists or professors. However, we are mindful that a majority of the majors will be seeking employment directly after graduating from college. For that reason, our curriculum is flexible and provides students with a number of options to better prepare them for a job.

### Other Information

All coursework taken for the Physics major or minor must be completed with a grade of “C-” or better.

Physics majors must also take the two assessment tests (Major Field Test and Local test) and complete the exit interview.

Apart from PHYS 1154, PHYS 1164 and PHYS 1950, no 1000-level courses may count toward the major requirements in physics. However, they do count as electives for various other college degrees.

Physics majors should strive to take as many of the courses in modern physics (PHYS 4210, PHYS 4220, PHYS 4230) and electronics (PHYS 3500) as their program will permit.

The senior project must be approved and the department chair notified at least eight months prior to graduation as a Physics major and the student must register for either PHYS 4950 or PHYS 4960.

Upper division courses (3000-level or higher) will assume that students have at least some experience with, and ability to use, computers for solving physics problems.

Physics is also offered as a concentration in the Division of Continuing Studies. More information can be found at: http://www.unomaha.edu/dcs/bgs.php.
