Physics provides the fundamental understanding of all things in the natural world, from the smallest subatomic particles to the largest astronomical objects in the universe. Students of physics develop strong problem-solving and analytical skills. The knowledge and skills obtained from the study of physics are a fundamental part of a liberal arts education. Physics is also the most basic science and provides the foundation of understanding on which all the sciences are built. Consequently, physics knowledge and skills are essential for future work in any area of science. Physics is both an experimental and a mathematical science. The application of mathematics to physics has been extremely successful. Thus, physics courses provide a rich source of examples and valuable techniques for those interested in mathematics.
Physics 201-202, University Physics, is the introductory survey course required for physics majors, pre-engineers and chemists. It is also recommended for mathematicians, biologists, pre-medical students and, in general, anyone who has taken high school physics and is taking calculus. Physics 101-102, College Physics, is similar to the above but has broader and less deep coverage, and uses mathematics only at the pre-calculus level. It is recommended for the general student and for science students who will not take calculus.
A physics major prepares the student for (1) graduate study in physics or most engineering disciplines; (2) a technical career in industry, government or the military; (3) a career in many fields in which problem-solving and analytical skills are needed; and (4) a teaching career in secondary school physics or middle school science after completing Teacher Education courses and certification requirements.
The physics major has three levels of courses: 200 level, 300 level, and 400 and 500 level. It is recommended that physics majors take the 200-level courses (Physics 201 and 202) in their freshman year, the 300-level courses in their sophomore year (Physics 303 and 310 in the fall, Physics 304 and 311 in the spring), and the 400- and 500-level courses in their junior and senior years. However, it is also possible to obtain a physics major starting in the sophomore year. Students starting the major in the sophomore year would take Physics 201 and 202 in their sophomore year and then take the 300-level and 400- and 500-level courses in their junior and senior years. The physics course prerequisites and course schedule have been designed to allow starting the physics major in either the freshman or the sophomore year. The 400- and 500-level courses required for the physics major average to five hours per semester during the junior and senior year if the student starts the major in their freshman year. If the physics major is started in the sophomore year, the average physics course load increases by two hours per semester (from five to seven) during the junior and senior years.
The Outstanding Physics Senior Award is given each year to the senior physics major who achieves the highest grade-point average, above 3.500, in all of his or her physics classes.

PHY 480, 481, 482, 483: Research in Magnetism
Credits 1PHY 490: Quantum Mechanics I
Credits 3The probabilistic theory of particles and their interactions has been very successful since its early forms treated quantization of radiation, electron photon interactions and atomic energies (Planck 1901, Einstein 1905 and Bohr 1913). Modern quantum mechanics deal with particles described as wave packets having a range of positions and momenta. This explains both the particle and wave effects observed. These wave packets are solutions of the Schrodinger wave equation and involve both space and time. The formal theory involves finding wave function solutions for harmonic oscillators, the hydrogen atom and other systems. Physical properties of these systems are extracted from these wave functions through the use of mathematical operators. This course is essential for those wishing to pursue graduate study in physics or related areas. Required in the field of concentration. Prerequisites: PHY 304 and PHY 311. Offered each fall.
