Physics
and Astronomy
The word physics originates from the Greek word for nature. Physicists
attempt to understand the basic principles that govern the behavior
of the natural world in which we live. The courses in physics and
astronomy are designed to serve both students interested in science
as an important part of a general education and those desiring intensive
training in physical science. Students may major in physics as preparation
for further professional training in physics, astronomy, or engineering,
or as excellent background for careers in other fields such as medicine,
law, biology, geology, and secondary-school science teaching. Physics
and Astronomy students at Oberlin have opportunities to work closely
with faculty members on research projects during academic terms,
winter terms, and summers.
Advanced Placement. Students who earn sufficiently high scores
on advanced placement examinations in physics will be given credit
for all or part of Physics 103 and 104 or Physics 110 and 111 according
to the following schedule:
Physics B examination: Students earning a score of 4 will receive
four hours of credit for Physics 103; students earning a score of
5 will receive eight hours of credit for Physics 103 and 104.
Physics C examination (Mechanics): Students earning a score of 4
or 5 will receive four hours of credit for Physics 110.
Physics C examination (Electricity and Magnetism): Students earning
a score of 5 will receive four hours of credit for Physics 111.
Students earning any credit through these examinations will receive
full QP credit.
High-school students who might wish to major in physics should take
the calculus-based Physics C courses and examinations, if possible.
Students who have received advanced placement in either physics
or mathematics and who are considering physics as a possible major
should consult the chair of the Physics and Astronomy Department
upon arrival in Oberlin regarding course selection and major requirements.
Although Physics 103 and 104 are not the normal prerequisites for
Physics 112 and upper-level courses, the Department is prepared
to arrange a transition to these courses for those who have earned
credit through the Physics B examination, have good backgrounds
in mathematics, and are interested in majoring in physics.
Entry-Level Course Sequence Suggestions. Students considering
a major in physics who qualify for Mathematics 134, 231 or 234 as
freshmen should take those courses and Physics 110, 111. Those without
advanced standing in mathematics should take Mathematics 133, 134
as freshmen and Physics 110, 111 as sophomores; such students may
take the full graduate study preparation program with the exception
of Physics 410 and Physics 411, and be prepared for graduate work
in physics.
Physics 110, 111, and 112 provide training useful to students of
any of the physical sciences or mathematics. Students majoring in
the life and earth sciences are also encouraged to take these courses
if they have the necessary mathematical background.
Physics 103, 104 are primarily for students majoring in the life
and earth sciences. With the permission of the Department an exceptional
student who has taken all or part of Physics 103, 104 may use it
as background for further work in physics.
Physics 50-70 are designed for College and Conservatory students
whose primary interests may not lie in the natural sciences but
who wish to have a first hand acquaintance with the techniques and
results of physical science.
Major Work. At present the Department offers only a major in
physics. Concentrations in astronomy and materials science are presently
under consideration but are not yet available. Students who wish
to become professional astronomers should consult Mr. Stinebring
to arrange a program of courses (within the framework of a physics
major) that will permit admission to graduate study in astronomy.
A physics major is required to pass Physics 110, 111, 112, 314,
414, and at least three courses chosen from Physics 310, 311, 312,
410, 411, and 412. Prerequisites for these courses include Mathematics
133, 134, 231, and 234. This minimum program is appropriate for
students using physics as preparation for careers in fields such
as medicine, law, business, or secondary-school teaching. (Such
students will also find courses in chemistry, biology, and computer
science to be valuable.) Students who wish to pursue physics as
a career in research or in college or university teaching should
take the graduate study preparation program, which consists of all
the courses listed above (i.e., it includes all six of Physics 310,
311, 312, 410, 411, and 412). A graduate of this program could pursue
undelayed full-time graduate study in physics or could enter certain
positions in industrial or governmental laboratories.
Computer
applications are important in all branches of physics and astronomy.
We urge all majors to consult their advisors about obtaining the
appropriate background.
Minor. The minor in physics consists of Physics 110, 111,
112, and two courses numbered between 200 and 450. At least three
of these courses must be taken at Oberlin.
Honors.
The honors program is open to outstanding senior-year major students
at the invitation of the Department. Students in this program will
normally be expected to complete the graduate study preparation
program of courses described above and must carry out a special
project in experimental or theoretical physics or astrophysics under
the direction of a member of the department. Honors students write
a thesis based on their work and take comprehensive examinations.
The physics major requirement of Physics 414 may be waived upon
request for an honors student whose project is in experimental physics.
Other Programs. Students with special interests are encouraged
to include physics and astronomy courses in an individual major,
or to plan a double major. Those interested in careers in engineering
may take a physics major, or they may consider the Combined Liberal
Arts and Engineering Program described under "Engineering" in this
catalog.
Winter Term. Physics and astronomy faculty will consider sponsoring
student-initiated experimental or theoretical (reading) projects
in areas of physics or astronomy. Staff members have special interests
in the areas shown below.
Mr. FitzGerald: physics of sports, investigation of fullerene materials.
Ms. Ijiri: materials science (particularly magnetic materials). Ms.
Keller: optics, physics education. Mr. Richards: acoustics, general
experimental physics projects. Mr. Scofield: experimental solid state
physics, solar energy (particularly photovoltaics), energy use in
buildings. Mr. Stinebring: radio astronomy, pulsars, cosmology, instrumentation,
image processing. Mr. Styer: relativity for non-scientists, mini-research
projects in theoretical physics.
Astronomy
Students who wish to become professional astronomers should consult
Mr. Stinebring to arrange a program of courses (within the framework
of a physics major) that will permit admission to graduate study
in astronomy.
Courses for a general audience. College and Conservatory students
whose primary interests may not lie in the natural sciences but
who wish to have a first-hand acquaintance with the techniques and
results of astronomy should consider ASTR 100.
100. Introductory Astronomy 3 hours
3NS, QPh
First Semester. The universe is a big and beautiful place. It is
remarkable how much we have been able to learn about the universe
from the photons that fall upon our telescopes and from the power
of the scientific process. This course, designed primarily for students
with little scientific background, is an introduction to what we
know about astronomy and how we know it. We will study the light,
the tools of astronomy, stars, galaxies, and cosmology. Emphasis
will be placed on the scientific discovery process. We will also
cover sky basics such as seasons, moon phases, eclipses, constellations,
using in-class presentations, the Taylor Planetarium, and the observatory.
There will be required participation in five planetarium sessions
(half an hour per biweekly session) and four observatory sessions
during the semester. Enrollment Limit: 120.

Courses with Physics and Astronomy prerequisites
152. Dark Matter and the Fate of the Universe 2
hours
2NS
Second Semester. First Module. Matter in the universe makes its
presence known through gravitational effects, particularly on the
dynamics of galaxies and clusters of galaxies. The amount of gravitating
matter in the universe is 30 to 100 times the amount of matter visible
through telescopes, leading to what has been called the dark matter
or missing mass problem. We will explore this forefront problem
using Newtonian dynamics. We will also investigate how the density
of matter and the probable existence of cosmic anti-gravity affect
the eventual fate of the universe. Emphasis will be placed on the
observational underpinnings of cosmology. Prerequisite: PHYS 110
(or PHYS 103 with consent of instructor). Enrollment Limit: 20.

detail. By applying principles from classical mechanics, thermodynamics,
and introductory quantum mechanics, the underlying structure and
life history of stars can be explored. We will draw on basic physical
principles, introducing needed specialized topics, in order to understand
how mass and composition determine a star's energy output, lifetime,
temperature, and eventual fate. Supernova explosions, white dwarfs
and neutron stars will be discussed briefly. Prerequisite: PHYS
