Organizers (add @mpim-bonn.mpg.de to the usernames):

Andrea Bianchi - bianchi
Thomas Blom - blom

Andrea is leaving soon, so Thomas is looking for a new coorganier. Contact him if you are interested!

Past organizers:

Kaif Hilman - kaif

New mathematical schedule:

12.45-13.00: Short presentation of problems.
13.00-13.05: Democratic choice of a problem.
13.05-14.30: Questions from the audience and general discussion of the problem.

Food schedule: Ice-cream will be available at the end of the seminar at 14:30 in the tearoom. The organizers expect to raise about 0.50 Euro per serving of ice-cream. Optionally, people may also choose to gather for lunch at 12:15 at the MPIM tearoom before the seminar.
