Courses in Physics (Division 444)

Since the Physics Department discourages students from changing midstream from Physics 140 to Physics 125 or from Physics 240 to Physics 126, it is important that students choose the first course of a physics sequence with care. Prospective engineers, physicists and chemists should elect Physics 140/240 rather than Physics 125/126 because concentration programs in these areas require the Physics 140/240 sequence. In the case of some departmental concentration programs (e.g., biology) or in special individual circumstances, students can elect or are encouraged to elect the Physics 125/126 sequence. Some advisors will advise all students who have had calculus to elect Physics 140/240. Physics 140/240 can be elected by all students who have had calculus, but it should be elected only by students who enjoy solving difficult problems and who think that they will be good at it.

105. Origin, and Fate of Life, Stars, Galaxies, and the Universe. (1). (NS).

This course will cover the birth, evolution, and death of astrophysical systems including planets, stars, galaxies, and the universe as a whole. Particular emphasis will be given to the long-term fate of these systems and their corresponding effects on life in the universe. Two lectures per week will be given. Students will read articles from selected books and journals and will be evaluated on both class participation and a final ten-page paper. This course has no prerequisites and will be presented with a minimum of mathematics. Cost:2 WL:3 (Adams)

106. Everyday Physics. (3). (NS). (BS).

This course examines everyday phenomena and current technology in terms of physical concepts and laws. The subjects examined are wide ranging and the discussion focuses on discovering common underlying themes. Examples of topics covered include: lasers, tornadoes, rainbows, computers, and satellites. This class emphasizes concepts rather than mathematical models. Grades are based on homework and exams. Curiosity is the major prerequisite. Cost:2 WL:5 (Sanders, Hegyi, Orr)

115. Living with Physics. Two and one-half years of high school mathematics, including trigonometry. No credit granted to those who have completed or are enrolled in Phys. 125, 140, or 160. (3). (NS). (BS).

Physics 115 is a descriptive introduction to Physics for non-science concentrators who do not have an extensive mathematical background. Students will be exposed to both classical and modern conceptions of the physical world. Critical evaluation of ideas through the use of the scientific method will be stressed. Classical concepts involving easily measurable physical quantities will be related to everyday life through a series of lecture demonstrations, take-home exercises, and experiments. At the same time, modern ideas ranging from the nature and evolution of the universe, to the world of the atom and of elementary particles will be discussed. It is hoped that students who complete the course will be in a better position to evaluate new and existing ideas in all areas of life by applying those methods which are used in the evaluation of physical theories. The final course grade will be based on homework assignments, a midterm exam, and a final exam. Cost:2 WL:4 (Freese)

125. General Physics: Mechanics, Sound, and Heat. Two and one-half years of high school mathematics, including trigonometry. Phys. 125 and 127 are normally elected concurrently. No credit granted to those who have completed or are enrolled in 140 or 160. (4). (NS). (BS). (QR/1).

Physics 125 and 126 constitute a two-term sequence offered primarily for students concentrating in the natural sciences, architecture, pharmacy, or natural resources; and for preprofessional students preparing for medicine, dentistry, or related health sciences. Physics 125 and 126 are an appropriate sequence for any student wanting a quantitative introduction to the basic principles of physics but without the mathematical sophistication of Physics 140 and 240. Strong emphasis is placed on problem solving, and skills in elementary algebra and trigonometry are assumed. While a high school level background in physics is not assumed, it is helpful. Physics 125 and 126 are not available by the Keller plan.

PHYSICS 125 covers classical mechanics (laws of motion, force, energy and power) and mechanical wave motion (including sound waves). The final course grade is based on three one-hour evening examinations, class performance and a final examination. Physics 127 should be taken concurrently. Cost:3 WL:5 (Aronson)

Physics 140, 240, and 242 constitute a three-term sequence which examines concepts in physics fundamental to the physical sciences and engineering. This introductory sequence uses calculus, and, while it is possible to elect Physics 140 and Mathematics 115 concurrently, some students will find it more helpful to have started one of the regular mathematics sequences before electing Physics 140. The introductory sequence is primarily designed to develop a skill: the skill to solve simple problems by means of mathematics. Developing this skill requires daily practice and a sense for the meaning of statements and formulas, as well as awareness of when one understands a statement, proof, or problem solution and when one does not. Thus one learns to know what one knows in a disciplined way.

The topics in Physics 140 include: vectors, motion in one dimension, circular motion, projectile motion, relative velocity and acceleration, Newton's laws, particle dynamics, work and energy, linear momentum, torque, angular momentum of a particle, simple harmonic motion, gravitation, planetary motion, pressure and density of fluids, and Archimedes' principle. Evaluation is based on performance on 3 evening hourly examinations (see Time Schedule for dates and times) and a final examination. Cost:3 WL:5 (Dershem)

Sections 035 and 036 &shyp; Keller Plan. Certain sections of Physics 140 are offered by the Keller Plan, a self-paced program without formal lectures. These sections are marked PSI in the Time Schedule. An information sheet describing the format of Keller Plan offerings is available in the Physics Student Services Office (2061 Randall Lab). Students who want to elect Physics 140 by the Keller Plan should read this information before registering. (Ross)

A number of physics concepts and laws (e.g., related to gravity, motion, energy, atoms, quarks and leptons, phases of matter) will be discussed, a few in depth. All will be examined along with their historical context, the ways by which they are tested, in what sense we believe them, and what impacts they have had on the development of science and society. The student will learn something about where scientists are today in trying to understand the natural world. The grading will depend on approximately three writing assignments (one based on an original historical work of physics, one based on something involving physics to be selected by the student, and one based on the impact of physics on superstition) plus two tests, one oriented towards facts and relationships and one oriented towards concepts. Cost:2 WL:4 (Kane)
