These lecture notes are the original material of Professor Charles Ladd, who taught the class every year from 1960 until 2001, refining the notes each year. Starting in the spring of 2003, the class was taught every other year by Professor Andrew Whittle and Dr. Lucy Jen. They have added their own materials and methods to teaching the class, but these lecture notes remain the foundation of the teaching materials.
In the table below, the topics column lists the subject of each lecture session, and the lecture notes link to that session’s handout.
