The study of physics, generally regarded as the most fundamental of the sciences, is an important part of a liberal education. Introductory courses in physics and astronomy are designed to give students a broad background in the fundamentals of the discipline, an introduction to the logic and philosophy of science, and insight into the understanding and applications of contemporary physics and astrophysics. Advanced courses provide greater depth and sophistication as the student's background in physics and mathematics develops. Laboratory investigation, designed to accommodate the student's particular needs, provides direct experience of the central role experimental research plays in the advancement of science.
A major program can be structured to meet the individual needs of students planning graduate study in physics or engineering, as well as those considering a variety of careers in business, teaching, government, law, or medicine. The requirement for a major is nine courses in physics or astronomy, including the following seven (usually taken in the order given): Physics 108, 222, 211, 231, 301, 308, and 458 (senior thesis). The additional two courses must include one of the following: Physics s30, s45, or any physics or astronomy course numbered 232 or higher. Physics 107 may count toward the major requirement if it is taken in sequence with Physics 108. Students planning graduate study in physics or engineering are encouraged to take at least six additional courses numbered 300 or higher. In exceptional cases, a student who otherwise meets the nine-course requirement may petition the Department to take a comprehensive examination in lieu of the thesis project.
A student interested in using physics as a basis for an engineering career should inquire about the Bates "three-two plans" with Dartmouth, Rensselaer, Columbia, Washington, or Case. Ask for a descriptive brochure. By careful planning at registration time, similar combination curricula may sometimes be worked out with other engineering institutions.
General Education. The following sets are available: Astronomy 101-102, 101-104, 102-104; Physics 101-102, 103-104, 107-108. The quantitative requirement may be satisfied through one of the following: any course in astronomy or physics, or any unit numbered s30 or higher. The following units may serve as options for the third course: Physics s23, s30, or s33. A student may request the Department to approve a two-course set not currently designated, but must do so before registering for the set.
101. An Introduction to the Large Scale. Although Immanuel Kant proposed the existence of galaxies more than two hundred years ago, most of what we know about the galaxies has been learned in recent decades. Driving this sudden explosion of knowledge are the new technologies of radio, infrared, X-ray, and gamma-ray astronomy. This course explores the methods of contemporary astronomical research as they have been applied to the modern discovery of the galaxies. Laboratory exercises introduce techniques of astronomy. Facilities include the Stephens Observatory 0.3-meter telescope, the planetarium, and portable telescopes. Enrollment is limited to 16 per section. [Mr. Wollman].

104. The Evolution of Cosmology. As long as there have been natural scientists, there have been efforts to comprehend the size, shape, and internal motions of the universe as a whole. The application of Einstein's general theory of relativity to these questions has yielded new and unexpected possibilities. This course traces the essential developments in our perception of the universe, with special attention to contemporary models. Enrollment is limited to 16 per section. Mr. Notte. W

There is more emphasis on conceptualization than on computation, but geometry and elementary algebra are used. Enrollment is limited to 16 per section. Staff. F
102. Revolutions in Physics: Light and Matter. A study of the conceptual revolutions begun by Young in 1802 and Einstein in 1905 concerning light; and by Thomson, Bohr, and deBroglie from 1897 to 1923 concerning atoms. The culmination of these revolutions in the quantum theory and its Copenhagen interpretation is examined for insight into the Heisenberg uncertainty principle and the wave-particle duality of radiation and matter. Laboratory work and the mathematical level are similar to that of Physics 101. Enrollment is limited to 16 per section. Staff. W
103. Musical Acoustics. An introduction to sound and the acoustics of musical instruments through the study of mechanical vibrations. Concepts such as waves, resonance, standing waves, and Fourier synthesis and analysis are developed and applied to discussion of hearing, scales and harmony, musical instruments, the human voice, and auditorium acoustics. No background in physics or mathematics beyond algebra is assumed. Demonstrations and laboratory exercises are integrated with class work. This course is essentially the same as Physics s24.

s23. Einstein: The Man and His Ideas. An introduction to the life of Albert Einstein and to his Special Theory of Relativity. The unit begins with a study of Einstein's life, through biographies and his own writings. Next, his Special Theory of Relativity is developed, and its seemingly bizarre predictions about time, length, and mass are discussed.

Finally, some of the philosophical implications of the theory are discussed, as well as some of its applications to nuclear weapons and modern theories of the universe. Permission of the instructor is required. [Mr. Semon].
s25. Alternative Introduction to Physics. The study of physics is a creative and satisfying intellectual adventure shared by a relatively small number of people, most of whom are men. The instructors believe that by taking advantage of the Short Term schedule flexibility, "we can make this experience attractive to a more diverse group." Physics s25 is an alternative to Physics 107; it emphasizes student-directed laboratory exploration, classroom discussion, and collaboration. As a complementary activity, visiting middle-school students participate in laboratory investigations designed by the course participants. Ongoing group discussion of unit activities and procedures is aimed at creating a more inclusive and welcoming atmosphere. Students who are interested in physics but discouraged by perceptions of the field are especially encouraged to enroll. Recommended background: Mathematics 105 or high-school calculus.
