From Wikipedia, the free encyclopedia
Hi everybody.
I started editing Wikipedia in September 2003, and registered a few days later. As you can see from my list of contributions, I am mainly interested in mathematics, but also in the history and politics of Germany and Austria and other European countries, as well as in the United States and Israel.
What does my name mean? Why the hell is it 4? Well, nobody knows, actually...
If you want to leave me a message, please use my talk page.
