MaterialThis course will begin by teaching the basic laws which govern familiar motions of "large" objects like planets, cars, and marbles--"particles," in the physics lingo we will use.We will then move on to learn about a variety of different kinds of waves, like water waves, sound waves, and light waves. Finally, we will venture into the Alice-in-Wonderland world of "quantum physics," which governs the motion of "small" objects like electrons and atoms. In quantum theory, objects simultaneously behave like waves and particles. |

Course componentsThis course has the following instructional components, which are discussed below. The components are designed to complement one another in order to give you many different ways to learn the material.1. Reading. Associated with each lecture is some reading material from the textbook by Hewitt, or, later from a book chapter which I will hand out. You are expected to read this material BEFORE YOU COME TO LECTURE. We will rely primarily on the reading for the exposition of ideas and concepts. 2. Lectures. We will all participate in learning during the lecture time. I will perform lecture demonstrations to illustrate important concepts and phenomena directly--this is something that can't be gotten from a book. I will work examples. And you will work simple, ungraded "in-class exercises" whose purpose is to let both you and me know what you do and don't understand. The lecture will NOT be primarily for exposition of ideas and concepts--that's what the reading is for. Of course, questions about the reading are strongly encouraged. 3. Discovery sessions. (5 during quarter, attendance mandatory) We have developed for this course a series of "discovery sessions," in which you will get a "hands-on" experience with physics. In groups of three, you will use varied apparatus and state-of-the-art computer and video equipment to explore various aspects of motion, waves, and sound. 4. Discussion sections (On weeks with no discovery sessions, attendance mandatory). In discussion sections, the Teaching Assistant Anshuman Maharana will help you with the homework, and with problem-solving. 5. Homework. Each week you will be assigned homework problems. The purpose of the homework is to help you internalize the concepts we are covering, so that you will be able to apply them to understanding new situations and phenomena.

| 2/11 | Midterm | It has been pointed out to me that you did not do the experiment which was referred to in problem 28. I apologize for this. I will give everyone full credit for problem 28, parts b, c, and d. Part a was independent of b, c, and d, and something we discussed in class, so we will grade that part. Since this course is not graded on a curve, people's grades can only be helped by this. | multiple choice
