Courses, Learning and Teaching Methods and Literature

Courses and Schedule

Learning and Teaching Methods

Lecture: presentation

Tutorial: The tutorial is held in small groups. In the tutorial the weekly exercises are presented by the students and the tutor. They also provide room for discussions and additional explanations to the lectures.

The courses of the module are offered during the winter semester only. Students taking the repeat exam after the summer semester may visit the courses to PH0012 Theoretical Physics 4B (Thermodynamics and Elements of Statistical Mechanics) to recapitulate the contents at least in parts.

Module Exam

Description of exams and course work

There will be an oral exam of about 40 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested at least to the given cognition level using comprehension questions and sample calculations.

For example an assignment in the exam might be:

  • Determination of the chemical potential of a perfect gas in the canonical ensemble
  • Presentation of properties of the Ising model

After successful participation in the tutorials a certificate ("Übungsschein") is issued as mid-term. Successful participation is active participation in the tutorials and at least 50% of exercise points.

There will be a bonus (one intermediate stepping of "0,3" to the better grade) on passed module exams (4,3 is not upgraded to 4,0) if a certificate ("Übungsschein") is present before the oral exam.

Exam Repetition

The exam may be repeated at the end of the semester. There is a possibility to take the exam in the following semester.

Current exam dates

Currently TUMonline lists the following exam dates. In addition to the general information above please refer to the current information given during the course.
