2002-Present Laboratory Coordinator and Adjunct Professor at Linfield College

I oversee the instruction of the General Physics Laboratory courses, which I designed and for which I have written the manual. I also designed and now teach the Advanced Physics Laboratory courses. These courses emphasize research methods and writing skills. Classical Mechanics, Physical Optics, Quantum Mechanics, and General Relativity are the courses that I have been teaching recently.

I have become interested in Chinese culture and language. This inspired me to audit Chinese classes for several years. In January 2002, 2004, and 2006 I co-taught the travel courses,
"Physics and Technology of China",
"Information Technology in China", and
"China's Approach to Environmental Problems" with Dr. Tianbao Xie of Linfield's physics department.

1988 - 2002 Associate Professor at Linfield College

Teaching General Physics has been a large part of my assignment here. I have been active in designing and writing the instructions for new experiments to be used in the laboratory part of this course. The instructions are now ready for binding in the form of a laboratory manual. Another major part of my assignment has been teaching Concepts of Physics. This course does not have a laboratory part, but I make use of many demonstrations. Other courses that I have taught regularly include Modern Physics, Electricity and Magnetism, Statics and Dynamics, Circuits, and Engineering Orientation.

In the summer of 1992 I worked for two months at the Los Alamos Meson Physics Facility on the LSND neutrino scattering experiment. A student of mine, Colin Starr, and I wrote a technical note, and he has written his senior thesis on this work.

I spent the summer of 1989 doing research at the Linfield Research Institute. Studies in Surface Physics are the primary concern here. Scientists at the institute have developed the Thermionic Projection Microscope used for measuring the work functions of separate crystal planes. Electrons emitted from the planes are collected on a phosphor screen, and a video camera is used to produce a digitized image of the intensity pattern. Numerical calculations yield the work function associated with each plane. My work involved perfecting the instrument, analyzing the electron trajectories, and measuring the work functions of tungsten.

During my first semester here I assisted Dr. Densley Palmer, who was director of counseling, in teaching a course called Study Skills. The purpose of this course is to help students admitted on probation to get a good start in college.

1987-l988 Visiting Assistant Professor at Lewis & Clark College

This was a temporary position in which I replaced a professor who was on sabbatical. During this year I taught Invitation to Physics, which was a survey for non-science majors; Modern Physics, in which Kenneth Krane's book was used; General Physics II, in which University Physics by Sears, Zemansky and Young was used; and Electronic Instrumentation from Digital and Microprocessor Electronics for Scientific Application by Dennis Barnaal. I also taught junior and senior laboratory courses in which students work individually on projects. One student was constructing a dye laser pulsed by a nitrogen laser. Several other students were determining the acceleration of gravity precisely by means of an air-suspension gyroscope whose precession period was determined by reflecting a laser beam off the gyroscope into a photocell interfaced with a Commodore 64 computer. Another student was determining the speed of sound in metal rods by several methods. I was also in charge of arranging the Friday afternoon seminar.

1985-1987 Associate Professor at University of Southern Colorado

This was a temporary assignment in which I replaced a professor who was on leave. I taught the following courses: Principles of Physics I and II, Principles of Physics Laboratory, General Physics III (Modern Physics), Physics of Sound, Solar Energy, Lasers, and Relativity.

1978-1985 Professor at Colorado Mountain College

Colorado Mountain College is a junior college that offers a two-year transfer program in engineering, science and mathematics. I was in charge of the physics portion, which consists of Introductory Physics and three quarters of General Physics. The textbook was Fundamentals of Physics by D. Halliday and R. Resnick. Much of my effort was directed toward developing the laboratory parts of these courses where I introduced experiments using the computer for analyzing data and studying planetary motion and electric field configurations. I emphasized electronics with the use of the oscilloscope and introductory studies of transistors and associated circuits. In addition to physics, I taught the following courses on a regular basis:


I served three years on the Peer Evaluation Committee and one year on the Professional Standards Committee.

My position and the physics offerings at Colorado Mountain College were terminated because of low enrollments in physics. The total enrollment at the campus was about 600, so it was common to have only 6 students in a General Physics course.

1977-78 Assistant Professor at University of Southern Colorado

This was a temporary assignment in which I replaced a professor who was on leave. I taught General Physics for which the book Fundamentals of Physics, by D. Halliday and R. Resnick, was used. I also taught the laboratory sections for General Physics and for Principles of Physics. I served as Advisor to the Society of Physics Students.

1975-1977 Assistant Professor at Eastern Oregon State College

This was a temporary assignment in which I replaced professors who were on leave. At Eastern Oregon State College, all science courses intended for non-science majors are presented as three-week modules. I taught the following: Cosmology, Radioactivity, Kinematics, Dynamics, Optics and Light, Electricity and Magnetism, and Relativity. I also taught a course called Engineering Orientation.

I taught Physics I, including laboratory. The book for this course was Fundamentals of Physics, by D. Halliday and R. Resnick.

The upper division courses that I taught were Modern Physics for which I used the book Quantum Physics, by R. Eisberg and R. Resnick, and Theoretical Physics for which I used the books Classical Mechanics, by V. Barger and M. Olsson, and The Electromagnetic Field, by A. Shadowitz.

1975 - Summer Instructor at Michigan State University

I taught the second half of the course Theoretical Mechanics for which I used the book Classical Mechanics, by H. Goldstein.

1973-1975 Research Associate and Laboratory Instructor at Lakehead University

I worked on an experimental research project with Dr. John Hart. We investigated the charging effect of particles of solid carbon dioxide striking a metal surface.

I also had charge of the laboratory and discussion classes for two General Physics courses with a total of 160 students. My work involved assembling the apparatus, teaching six laboratory classes each week, and instructing at problem solving sessions.

I also supervised ten graduate and undergraduate students who assisted me in the laboratory and in the grading of reports and homework assignments.

1972-1973 Assistant Professor at Northern Michigan University

This was a temporary assignment in which I replaced a professor who was on leave. I taught the following courses: General Physics, an introductory course for pre-medical and biology students; Contemporary Physics, a non-mathematical course in modern physics for beginning physics majors and interested liberal art students; and Electromagnetic Theory, the standard undergraduate course for physics majors.

1966-1972 Research Assistant under Knoller Fellowship in Physics at Wayne State University.

I did the research for my Ph.D. in Theoretical High Energy Physics. This involved the computer calculation of cross section for three particle processes such as PP→PP, and comparison with experimental data.

1965-1966 Graduate Teaching Assistant in mathematics at Wayne State University.

1964-1965 Instructor at the University of Pittsburgh at Bradford

I taught Calculus, General Physics, and Physics and Chemistry for Elementary Education majors.

1961-1964 Graduate Assistant at the University of Pittsburgh.

I did the research for my M.S. degree. This involved building a spark chamber, including the vacuum system and associated electronics, and analyzing the photographs. In addition, I worked with the 15 MeV cyclotron. I also had experience in instructing General Physics laboratories and grading homework assignments and examinations.
