Introduction to the course

What is physics? Why do we study it? How do we do it? These are some of the questions that we hope to answer in this class.

An introductory Physics course usually covers Mechanics, Thermal Physics, Electricity and Magnetism, Optics, and Modern Physics. Typically it takes two years to go through these subjects. We, on the other hand, will have only one year to cover all this material. A great challenge before us is to master the material in a short period of time, and do it well.

Another challenge is that this class consists of students with intention of pursuing rather different majors - mathematics, physics, and life sciences. The preparations and backgrounds are also very different. To address this challenge, we will focus on the most fundamental aspects of physics, emphasizing concepts and general approaches.

Organization

This course is being offered to freshmen classes of Mathematical and Physical Sciences and Life Sciences in SJTU College. Both classes will have formal lectures together on Tuesday (two lectures). On Thursdays, however, the two classes will have their own recitation sessions, which consist of one session on problem solving and another one on discussion emphasizing conceptual development.

Physics is an experimental science. Accompanied laboratory sessions are usually offered simultaneously as part of this course. Unfortunately the accompanied laboratory sessions of this course will be offered only in the Spring semester. Nevertheless, the importance of the experimental aspects of this course should NOT be lost.

Two-question surveys

At the end of each lecture on Tuesday, each student is required to fill in a survey. You should report one thing you have learned in the two lectures given that day that you feel is particularly interesting/intriguing to you, and one thing that you didn’t fully understand, or need further clarification. You will need to write down the date and your name on the survey and turn it in at the end of the class. The survey should take no more than a couple of minutes to complete.

Conceptual development

This class seeks to help you build a conceptual framework of physics. This will be attempted through activities in and outside the class. The lectures are meant to demonstrate explicitly how physical concepts are developed, what they mean, and how they can be applied in real world. The follow-up problem solving and discussion sessions, especially the latter, will provide an opportunity to internalize these concepts.

Reading

Reading materials that will be covered in class beforehand, and those that will not be taught at all, is an important part of this class. The purpose of the reading before the lecture is to get familiar with the material to be covered, and to bring some questions to which you can try to get an answer from the lecture. The benefit of reading the material after the lecture is to provide you with an opportunity to reflect and understand the physics discussed in the lecture. Below you will find a detailed list of what we will be covering each week, and the corresponding reading materials. You will need to read the assigned materials on time.

Problem solving and homework sets

Solving problems is an integrated part of learning. It is an effective tool to help you grasp physical concepts and build analytical skills. In addition to problem solving class that we will be offering, we will also have a homework problem set each week. The homework is due on Tuesday before the lecture. Each problem set is worth 2 points toward your grade.

Discussion

Learning and understanding is a complex process. It is common that you feel that you understand certain material but discover the opposite after you discuss with others. Indeed discussing is an effective tool for learning. It helps you identify what you don’t understand, and how things can be viewed or approached from different angles.

In addition to the weekly discussion sessions, both instructors and two teaching assistants will have office hours. These office hours will also provide you space, time, and a partner for discussing.

Self-education

A central goal of this course is to motivate and train students to study physics independently, and more broadly, to gain the ability of pursuing a life-long self-education. Reading, listening to lectures, solving homework problems, discussing with your instructors, teaching assistants, and fellow students, and most importantly, reflecting on the meaning of physics, are all tools for this pursuit.
