Zeit und Ort

Monday 14.00 - 16.15 and 16.15 - 17.00
N020 (kleiner Physikalische Hörsaal)

We will explore the physics of biological systems, including their origin, evolution, pattern formation, embryogenesis, biochemical networks, chemotaxis, gene regulation, high throughput methods, neural networks, game theory and econophysics of money. The lecture will include a short introduction in modeling of chemical networks with MatLab and reaction-diffusion systems with Comsol. It is a 3 hour lecture, 1 hour seminar, 6 Credit Points, Only the lecture results in 4 credit points). The lecture is for Master students, open to other discilines and background on Cellular Biophysics, Molecular Biophysics and Theoretical Biophysics is helpful and recommended. Lecture is within the Biophysics Program of the Physics Master
