My real name is Karl Hahn. When I created the account, I didn't know users could have blanks in their user-names. I've learned a whole lot about the mechanics of Wikipedia since then.
Interests: mathematics, chemistry, mathematical physics, astronomical algorithms, classical music, computer software, information theory, telecommunications.
