There are four lecture hours/week. A typical lecture starts by a short discussion and review of previously covered material. Students are engaged in the discussions via suitable questions. We then proceed to discuss new material. When a new concept is introduced, the students are asked to perform a short related calculation or answer a related question that tests their understanding. We then solve representative exercises. Active student participation is encouraged with questions.A concise summary of the lecture material, along with illustrative figures is contained in Powerpoint presentations.In the tutorial hour we discuss problems and applications, go over the solutions of assignments and answer student questions.The students are given 6-8 home assignments that they have to complete in a course of 7-10 days each. Student collaboration is permitted, but the preparation of individual reports is very strongly encouraged. Halliday, Resnick, Walker. Physics (translated in Greek).Young, Freedman.
