Welcome on my personal Wikipedia page!

From 2000 until 2008 I studied Physics at the Humboldt-Universität zu Berlin and finally got my diploma. Since 2005 I have an account at Wikipedia, beginning in 2006 I started contributing to this project. One thing I like is the possibility to directly import LaTeX commands (for formulae):

$j^{\mu }=\sum _{i=1}^{N}{\frac {\delta {\mathcal {L}}}{\delta (\partial _{\mu }\phi _{i})}}\varphi _{i}\quad ,\quad \varphi _{i}:=\left.{\frac {\partial \phi _{i}}{\partial \alpha }}\right|_{\alpha =0}$

(BTW: This Noether current fulfills the Continuity equation :-)

For further details look at my page in german.
