Purpose of the course
This is an advanced course on classical mechanics. The purpose of this course is to introduce the formal structure of mechanics such as variational methods, phase space flows and the techniques needed for further developments beyond classical few-body physics.
Many students are expected to know most of this material. They can skip the drudgery of sitting through a course by opting to take a drop test on August 27. Register for the drop test by sending me an email before August 20.
Pre-requisites for this course are two-fold. First, I will assume good working ability to solve for the motion or equilbrium of few body systems. Second, I will assume the ability to solve second order differential equations with constant coefficients. Both these abilities will be assumed at the undergraduate (B.Sc.) level. I will also assume a basic ability to use computers.
You will have to learn to use Mathematica. Here is a quick tutorial introduction to Mathematica: download it and try it out. In order to do this you will need an account on the servers in the computer center.
Performance evaluation will be based on assignments and tests. Tests will be given in the middle and end of the semesters (on 17 September and 29 November), and regularly throughout the course.
