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...)
