Math Jam

[pier4r]

I don't know if you participate in one, it was my first one (after years of being in Berlin. Damn me!) and was nice.

The problem is that the Berlin group has a wrong pointer on the official site, so many - I think - are discouraged that no one replies. A better hint is to search "Berlin math jam" on facebook.

In the best case one brings puzzles to solve. In the worst case one has puzzles from the organization.
