Jakob Werner
I’m a mathematician and computer programmer based in Regensburg, Germany. I enjoy fun and easy math questions, mostly within algebraic geometry. I like constructive mathematics, mainly for aesthetical reasons, and try to think and write constructively when possible.
I’m also interested in literature, history, sociology, music, economics and philosophy and I enjoy reading books from these fields.
I try to be friendly towards my fellow creatures, which of course has political implications.
