Lecture course Theoretical Biophysics summer term 2017

This course is MVBP2 in the modul handbook and is addressed to master students in physics with a background in statistical physics. Motivated bachelor or PhD-students are also encouraged to attend. There are two lectures each week, each for 90 minutes, plus weekly homework and exercises. Together you can earn 6 credit points from this course. This lecture can be used for the oral master examination if combined with e.g. the lecture on statistical physics or the lecture on simulation methods, or with two short specialized lectures (like non-linear or stochastic dynamics). The lecture takes place Tue and Thu 9.15 - 10.45 in room 106 at Philosophenweg 12 and is given by Ulrich Schwarz. The exercises take place on Wed 16.15 - 17.45 in room 105 at Philosophenweg 12. Earlier exposure to biology and biophysics (e.g. the experimental biophysics course in the winter term, bachelor courses on biophysics, biology courses) is helpful, but not required.
