### Polytopia: Over half of the polyhedra have been adopted

In case you haven't adopted your own polyhedron yet, hurry up! We are happy to announce that more than half of the polyhedra on polytopia.eu are already gone. On the website, you can find every polyhedron with up to nine vertices and we invite you to choose your favorite, give it a name, and realize it in one way or another.

"A mathematician is a machine for turning coffee into theorems". This is how Paul Erdős quotes Alfréd Rényi. (Yes, that's a bit complicated, this is why people assign this quote directly to Erdős.) In this spirit, we try to turn as much coffee into theorems, as possible. 50,000 cups of coffee is sufficient proof that at least the intake of the machines is working.
