Undergraduate nondegree programs: Minor in Physics, Astronomy Graduate degrees: M.S. in Physics, Astronomy; Ph.D. in Physics (including specialization in Astronomy) Web site: http://www.physics.uiowa.edu The Department of Physics and Astronomy provides comprehensive and rigorous instruction in all basic aspects of its subjects. It also provides research facilities and guidance in selected specialties for advanced individual scholarly work. All of the department's courses and advanced laboratories are taught by faculty members. Faculty members also supervise associated laboratories taught by graduate students. Enrollment in courses beyond the elementary level is typically 15 to 20 students; there is ample opportunity for individual work. Special introductory courses are offered for students majoring in physics and astronomy and for others with a special interest in these subjects. Total enrollment in physics and astronomy courses is approximately 1,700 each semester of the academic year and 150 during the summer session. The department has around 80 undergraduate majors, half of whom are honors students, and 60 graduate students. About 70 percent of graduates with bachelor's degrees pursue advanced study. Others find positions in government and industrial laboratories and in secondary school teaching. Some use their training as the basis for careers in other fields. Graduates with an M.S. or Ph.D. in physics or astronomy have opportunities for employment in universities, colleges, and research laboratories in government and industry. Undergraduate Programs
Students who wish to earn a double major in physics and astronomy must choose their course work carefully; see "B.A. or B.S.: Double Major in Physics and Astronomy" below. Bachelor of Arts students majoring in physics who are interested in science teaching and in earning a graduate degree may enroll in a joint degree program offered by the College of Liberal Arts and Sciences and the College of Education; see "Joint B.A./M.A.T. in Science Education" below.

Undergraduate majors who plan to pursue graduate study are advised to go as far as they can beyond the minimum requirements listed above, including further work in mathematics. In planning this work, they should be guided by the College of Liberal Arts and Sciences maximum hours rule: Students earning a B.A. or B.S. may apply a maximum of 50 s.h. earned in one department to the minimum 120 s.h. required for graduation, whether or not the course work is accepted toward requirements for the major; students who earn more than 50 s.h. from one department may use the additional semester hours to satisfy requirements for the major (if the department accepts them), and the grades they earn become part of their grade-point average; but they cannot apply the additional semester hours to the minimum 120 s.h. required for graduation. Students earning a B.S. with a double major in physics and astronomy may count more than 50 s.h. earned in the Department of Physics and Astronomy to the 120 s.h. required for graduation, but they must earn at least 56 s.h. in course work outside the department in order to graduate. Bachelor of Arts: PhysicsThe Bachelor of Arts with a major in physics requires a minimum of 120 s.h., including 48 s.h. of work for the major. It requires fewer physics courses than the B.S. and provides for a wider choice of electives. The program is designed for students who wish to gain knowledge of physics but do not plan a research-oriented career in physics. It is appropriate for those planning careers in medicine, law, science-related administration, business, or technical writing. It also provides a foundation for students interested in secondary school science teaching; see "B.A. or B.S. with Teacher Licensure" below. The physics major for the Bachelor of Arts requires the following courses or their equivalents. The department encourages students to do additional work. Students also must complete the College of Liberal Arts and Sciences General Education Program. Many 100-level physics courses have prerequisites; students should consult their advisors when choosing 100-level courses.
One of these:
B.A. or B.S. with Teacher LicensureThe physics major (Bachelor of Arts or Bachelor of Science) provides a foundation for students who are interested in teaching secondary school science. The University's Science Education Program offers a Bachelor of Science program that also provides a foundation for teaching, allowing students to choose an emphasis in biology, chemistry, earth science, or physics; see Science Education in the Catalog. Students who wish to teach must complete a bachelor's degree and the College of Education's Teacher Education Program (TEP). See Teaching and Learning (College of Education) in the Catalog for more information about the TEP. Interested students should contact the College of Education's Office of Education Services. Joint B.A./M.A.T. in Science EducationStudents interested in pursuing a graduate degree in teaching may apply to the joint Bachelor of Arts/Master of Arts in Teaching program offered by the College of Liberal Arts and Sciences and the College of Education. Designed for undergraduates in biology, chemistry, and physics, the joint program enables students to earn a B.A. and an M.A.T. in five years by beginning to earn graduate credit during their fourth year of undergraduate study and by counting up to 18 s.h. of qualifying credit toward both degrees. For more information, see "B.A./M.A.T. in Science Education" in the Teaching and Learning (College of Education) section of the Catalog. Interested students should consult an advisor. Bachelor of Science: Applied PhysicsThe Bachelor of Science with a major in applied physics requires a minimum of 120 s.h., including 60-83 s.h. of work for the major. It is intended primarily for students interested in a broad program of study in physics combined with a significant concentration of courses in an applied field that has immediate application to industry. The degree provides a foundation for a wide range of employment opportunities in high-technology industries, including research and development, product design and testing, sales, and quality control. It also is designed to include exposure to physics sufficient to allow the student to continue with graduate studies in either physics or astronomy. The program offers four areas of concentration: optics, solid-state electronics, computer science, and medical physics. A student also may design a customized concentration area in close consultation with his or her advisor and with departmental approval. An essential component of each concentration is successful completion of a one-semester industrial internship or practicum experience in a research laboratory (an applied physics thesis is required for the latter option). This requirement may result in the need for a ninth semester to fulfill all requirements. Because of this, the Four-Year Graduation Plan is not available for the major in applied physics. Well-prepared students will be able to complete the degree in four years. Students should work closely with their advisors on a graduation plan. The major in applied physics requires the following courses. Students are encouraged to take additional course work. Advisors can suggest electives that will enrich programs and help students prepare for graduate work. Students also must complete the College of Liberal Arts and Sciences General Education Program. Many 100-level physics courses have prerequisites; students should consult their advisors when choosing 100-level courses.

Graduate study in physics and astronomy is highly individualized. The department does not offer a Ph.D. in astronomy, but students may pursue a Ph.D. in physics with a specialization and dissertation in astronomy or astrophysics. Each entering graduate student is assigned a faculty advisor, who assists in preparing a plan of study and in guiding the student's progress. All graduate students who intend to pursue a Ph.D. in physics must pass the qualifying exam (see "Doctor of Philosophy: Physics"). In addition to offering graduate degree programs, the Department of Physics and Astronomy participates in an interdisciplinary doctoral program, the Program in Applied Mathematical and Computational Sciences (Graduate College). Master of Science: PhysicsThe Master of Science program in physics requires a minimum of 30 s.h. of graduate credit. It is offered with thesis or critical essay. The M.S. with thesis requires a thesis based on an original experimental or theoretical investigation by the student. The M.S. with critical essay requires a critical essay on the literature of a particular area of physics. The M.S. may be a terminal degree or a step toward a Ph.D. In either case, the final examination is oral, conducted by a committee of three faculty members. Each student's plan of study should provide for as much advanced work as his or her aptitude and previous preparation permit. All master's degree students in physics must earn the required 30 s.h. of graduate credit in courses numbered 170 or above, with at least 15 s.h. at the 200 level. They must maintain a g.p.a. of at least 3.00. Students who choose the thesis option must write a thesis based on an original experimental or theoretical investigation that they have conducted. Students may earn a maximum of 6 s.h. in 029:220 Individual Critical Study or 029:281 Research: Physics. Up to one-third of the graduate program may be taken in related scientific fields other than physics and mathematics (e.g., chemistry, astronomy, geology, engineering). Students who choose the critical essay option must conduct an independent study of the literature on a chosen topic and write a critical essay on that topic. Students may earn a maximum of 4 s.h. in 029:220 Individual Critical Study or 029:281 Research: Physics. Up to one-third of the graduate program may be taken in related scientific fields other than physics and mathematics (e.g., chemistry, astronomy, geology, engineering). Master of Science: AstronomyThe Master of Science program in astronomy requires a minimum of 30 s.h. of graduate credit. It is offered either with or without thesis. The M.S. may be a terminal degree or a step toward a Ph.D. in physics with specialization and a dissertation in astronomy or astrophysics. In either case the final examination is oral, conducted by a committee of three faculty members. Students in the thesis program earn the required 30 s.h. in courses numbered 170 or above, with at least 15 s.h. at the 200 level. They must maintain a g.p.a. of at least 3.00. The 30 s.h. must include at least 6 s.h. chosen from 029:233 Theoretical Astrophysics II, 029:234 Stellar Structure and Evolution, and 029:235 Special Topics in Astrophysics. Students may earn a maximum of 6 s.h. in 029:220 Individual Critical Study and 029:282 Research: Astronomy. Seminars do not count for credit toward the 30 s.h. requirement. Up to one-third of the course work may be in graduate courses in related fields, such as meteorology, geology, and electrical engineering; selection of such courses is encouraged. Students in the nonthesis program earn 18 s.h. of the required 30 s.h. in the core graduate courses 029:205 Classical Mechanics, 029:213 Classical Electrodynamics I, 029:214 Classical Electrodynamics II, 029:233 Theoretical Astrophysics II, 029:234 Stellar Structure and Evolution, and 029:235 Special Topics in Astrophysics. Students must maintain a g.p.a. of at least 3.00 in the core graduate courses. They may earn a maximum of 4 s.h. in 029:220 Individual Critical Study and 029:282 Research: Astronomy. Seminars do not count toward the required 30 s.h. Up to one-third of the course work may be in graduate courses in related fields, such as meteorology, geology, and electrical engineering; selection of such courses is encouraged. Doctor of Philosophy: PhysicsThe Doctor of Philosophy program in physics requires a minimum of 72 s.h. of graduate credit. Graduate students who wish to pursue a Ph.D. in physics must pass a qualifying examination in all principal areas of physics at the level of advanced undergraduate work. The examination, which may be repeated only once, is given each year before the beginning of the spring semester. Students must pass the qualifying examination before the beginning of their fourth semester of graduate work at The University of Iowa. All Ph.D. students must take comprehensive examinations; participate in advanced seminars; do original research in experimental physics, theoretical physics, or astrophysics; and prepare and defend a written dissertation based on this work. The program of study for the Ph.D. with a major in physics includes thorough course work in both classical and quantum physics for all students, whether their specialized research is to be in an experimental or a theoretical area. Students must take at least 24 s.h. of 200-level courses in the department, excluding 029:220 Individual Critical Study, 029:281 Research: Physics, 029:282 Research: Astronomy, and seminars. The following courses are required.
Advanced mathematics, such as complex variables and tensor analysis, is used freely in these courses. An introduction is given in 029:171 Mathematical Methods of Physics I and 029:172 Mathematical Methods of Physics II. The selection of less advanced course work depends on the adequacy of a student's preparation for graduate work; students' choice of more advanced and specialized courses depends on the direction in which their interests develop. After a student has chosen a research specialty, he or she must submit a formal thesis proposal and defend the proposal in an oral comprehensive exam. The appropriate thesis advisor then becomes the candidate's general advisor and the chair of the comprehensive and final examination committee. The comprehensive exam must be taken before the beginning of the fourth year of graduate study. Ph.D. candidates are not recommended for the degree until they have written the dissertation in proper form for formal publication and have submitted it for publication, with the approval of the research advisor, to a widely distributed, refereed scientific journal. AdmissionApplicants must meet the admission requirements of the Graduate College; see the Manual of Rules and Regulations of the Graduate College or the Graduate College section of the Catalog. Financial SupportStudents qualified for graduate study are encouraged to apply for fellowships and assistantships. Contact the Department of Physics and Astronomy chair. Research, FacilitiesThe department has an excellent library and a number of well-equipped laboratories and observatories, as well as a student computer cluster for which students can obtain accounts. Faculty, students, and staff access national supercomputers via the Internet. The central machine shop is fully equipped and staffed by skilled instrument makers and machinists, and there are electronics and machine shops for use by advanced students and research staff. Experimental research is conducted in astronomy (optical, radio, and X-ray), atomic and molecular physics, condensed matter physics, elementary particle physics, laser physics, medical physics, plasma physics, and space physics. Extensive facilities are available for construction of specialized research equipment and for data processing and analysis. State-of-the-art semiconductor materials and devices are grown in two molecular beam epitaxy machines. Ultrafast laser techniques are developed and used to probe electron transport, energy relaxation, recombination, and spin dynamics in the novel nanostructures grown in these machines. Experiments also are conducted on laser-induced coherent phenomena and coherent control of charge carriers in semiconductor nanostructures. The experimental condensed matter program is closely coordinated with the condensed matter theory group. Plasma physics is an active area of experimental and theoretical research. Laboratory experiments studying plasma processes of importance in various space and astrophysical plasmas are performed in a Q machine, including experiments on waves and instabilities in dusty plasmas. Additional laboratory and microgravity experiments with dusty plasmas include studies of Coulomb crystals, shocks, and complex fluids. Glow discharges for plasma processing applications are studied using laser diagnostics and numerical simulations. Wave propagation and plasma particle dynamics also are studied in collisionless plasmas through laboratory experiments. Laser techniques are developed for measuring plasma flow and following particle orbits. Plasma theory efforts include analytical and numerical investigations of magnetic reconnection and turbulence in space and astrophysical plasmas; collaboration with laboratory and space plasma experimental groups in strongly coupled dusty plasmas, waves, and instabilities; and free electron lasers and hydrodynamic turbulence. State-of-the-art laser systems are available for high-resolution spectroscopic measurement and ultrafast studies of molecular structure, for collisional relaxation and nonlinear optical effects in atomic and molecular systems, and for plasma diagnostics. Experimental research in elementary particle physics is carried out at Fermi National Accelerator Laboratory, Stanford Linear Accelerator Center, CERN in Switzerland, and other international laboratories. The present generation of high-energy experiments has been designed to probe both the strong nuclear force and the weak interactions. The department is well-equipped for research and instruction in observational astronomy. The primary optical instrument is a fully automated 15-inch telescope at a dark-sky site in Arizona. The telescope is equipped with CCD cameras and a variety of filters. There are 3-meter and 4.5-meter radio telescopes on the roof of Van Allen Hall, which are used for instruction and student research projects. Research programs in galactic and extragalactic radio astronomy are carried out using the facilities of the National Radio Astronomy Observatory, including the Very Large Array and the Very Long Baseline Array, one element of which is 10 miles north of campus. Current long-term research activities include studies of the center of the Milky Way galaxy; investigations of extragalactic radio sources; the formation of powerful winds in young, luminous stars; radio-wave scattering in the interstellar and interplanetary media; and interacting binary stars. A research program in X-ray astronomy has been established, and there is a laboratory for instrument development. Research topics in X-ray astronomy concentrate on observations of X-ray emission from black holes and supernova remnants, using existing spacecraft. Active theoretical research is carried on in astrophysics; atomic, molecular, and optical physics; condensed matter physics; elementary particle physics; laser physics; mathematical physics; nuclear physics; plasma physics; and space physics. An active mathematical physics seminar fosters the exchange of ideas between mathematics and physics. The primary emphasis of Iowa's program in experimental and theoretical space physics is on studies of cosmic and heliospheric physics, magnetospheric physics, and magnetosphere-ionosphere interactions. Facilities are available for designing and constructing spaceflight instruments. Investigators in the department have flown instruments for studying plasmas, energetic charged particles, auroral images, plasma waves, and radio emissions on a wide variety of terrestrial and planetary spacecraft, including Pioneer 10 and 11, Dynamics Explorer, Voyager 1 and 2, Galileo, Polar, Cassini, and Mars Express.
