Learning and Teaching Methods
In the lecture, the contents are first explained on a theoretical level on an electronic whiteboard (the slides can be downloaded from the lecturer's web site immediately after the lectures). Then, the algorithms are implemented in the computer algebra system Mathematica to study the practical applicability of the concept. Whenever possible, the students are asked for input during this process, and if a suggested approach fails (e.g. due to numerical instabilities), the causes are discussed and alternatives are presented.
Exercise sheets (which frequently include reproduction of the results of the lecture) are first worked on individually by the students and then discussed in small groups with a tutor.
Media
Presentations on an electronic Whiteboard, demonstrations in Mathematica, C and Python ; exercise sheets. Accompanying web page: http://users.ph.tum.de/srecksie/lehre
Literature
Much of the material in this course is covered in "Computational Physics: Problem Solving with Computers" by Landau, Paez and Bordeianu, WileyVch, ISBN 3527413154 (3rd ed.) The 2nd ed., ISBN 3527406263, can also be used.
Module Exam
Description of exams and course work
There will be a written exam of 90 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using calculation problems and comprehension questions.
For example an assignment in the exam might be:
 Use the trapezoidal rule to calculate the integral of a function and show that the result is exact for linear functions.
 What is the order of magnitude of the error for nonlinear functions (in terms of the step size and derivatives of the function to be integrated)?
 Taking into account the algorithmic error and the roundoff error, what is the optimum number of integration steps?
Participation in the exercise classes is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.
Exam Repetition
The exam may be repeated at the end of the semester.
