DESCRIPTION:Speaker: Przemyslaw Prusinkiewicz\nAbstract: In the landmark 19
 52 paper\, “The chemical basis of morphogenesis”\, Alan Turing proposed 
 reactions between diffusing substances as a general model for biological p
 attern formation. In the development of his model\, Turing abstracted from
  the growth of the tissues under consideration. Contrary to this assumptio
 n\, however\, feedback between patterning and growth is essential for nume
 rous morphogenetic processes in nature. This feedback can be formulated in
  geometric terms. Biochemical and biomechanical factors are then viewed as
  a lower level of abstraction\, from which the geometric properties of the
  patterning processes emerge. The geometric viewpoint highlights similarit
 ies between diverse morphogenetic processes in plants\, including the form
 ation of phyllotactic patterns (the arrangement of plant organs)\, the dev
 elopment of leaves\, and the development of inflorescences (flower cluster
 s). The presentation will be illustrated using interactive computational m
 odels and simulations that expose the conceptual beauty and simplicity of 
 several algorithms of plant development.
