Something about me
Travelling is my biggest hobby: I lived in eight countries for longer periods and have visited 84 of them so far. My aim: To get into the "1oo Countries Club"

Next to Sport und Gastronomy, Mathematics is another hobby of mine. In the seventies I found a new formula to calculate e:


 * $$e = \lim_{n\to\infty} \quad {\rm }\frac{n^n}{(n-1)^{(n-1)}} - \frac{(n-1)^{(n-1)}}{(n-2)^{(n-2)}} \quad {\rm for}\quad\left|n\right|>2.$$

(Unfortunately, this formula was published only once in the Internet, in Wikipedia...)
