 Aim: Aim:
-  * Main scientific goal +  * Introduce self-organized pattern formation (Turing patterns) 
-  * Didactive aim+  * Show the potential of qualitative/theoretical modeling
  
 Description: Description:
-  Step by step description of module + 
-  * Written such that other tutors can teach the same stuff+  Activator-Inhibitor models 
 +  * Theoretical introduction on Turing patterns (1951) 
 +  * Self-organized organizer 
 +  * large system size = periodic pattern 
 +  * change inhibitor diffusion and observe changing pattern wavelength 
 +  * half-wavelength system size and no flux bc. = spontaneous symmetry break of homogeneous init.cond. with max and min at opposite boundaries 
 +  * Fish coat pattern: Miyazawa et al. 
 +  * Trigger discussion: 
 +    * Parameters and variables do no longer correspond to molecules anymore 
 +    * What is the explanatory power of ‘blending model’? 
 +    * Bottom-up, top-down, middle-out
