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 counselors 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.

**108. Controversial Scientific Discoveries and Claims.
*** Algebra. (3). (NS). *

The course title is Controversial Scientific Claims and Discoveries, or "Incredible Science." The course will deal with several claimed discoveries which are of fundamental importance (if correct), are greeted with incredulity by the scientific community, stimulate considerable activity, and are subjected to exhaustive investigation which leads to verification or falsification. The science involved will all permit discussion without the use of mathematics beyond the high school level. Some recent examples of this genre are Cold Fusion, the so-called Fifth Force (which calls into question Galileo's assertion that all bodies fall at the same rate), Gravity Waves, Magnetic Monopoles (unaccompanied North magnetic poles), Fractional Charges (free particles whose charge is not a multiple of the electron's charge), and Polywater (a new form of water). Not-so-new examples include the discovery of electromagnetism, N-rays, observation of meteorites, and Mesmerism. We will study the science involved, the process by which the claim is resolved, and ethical issues (concerning both the presentation of the claim and appropriate forms of rebuttal). The form of the class will be a seminar with two meetings of 1-1/2 hours; the second half of each meeting will be devoted entirely to discussion and presentations by students. We will require a short paper from each student concerning each case studied, and a longer paper on a particular topic. There will also be a mid-term exam. Readings will be chosen both from the original scientific literature and secondary sources, including the popular press. (Sanders)

**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 Physics
125, 140, or 160. (3). (NS). *

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 xof 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 (Axelrod)

**125. General Physics: Mechanics, Sound, and Heat. *** Two

No credit granted to those who have completed or are enrolled
in 140 or 160. (3). (NS). *

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 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 hourly examinations (see * Time Schedule * for dates
and times) and a final examination.

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
