Martin Petrásek (*1980), Opava, Czech Republic

My native and working language is Czech, so this site is mostly in Czech language. If you need more information than English alternative pages on my server offers, dont hasitate to contact me directly throught the email, phone or form in my contact page.

Since 1996 I'm actively acting in czech media. I am strongly concerned in popularization of science in which I cooperate with many regional and countrywide magazines and newspapers. From 2000 to 2003 I became a publisher of two regional newspapers called "Opavsko - křížem, krážem" and "Opavský Inzert". My professional path has been terminated by unexpected tragical family affair in September 2003. I graduated in Theoretical Physics at Silesian university at Opava, Czech Republic. Since 2004 I am the PhD. student at the Institute of Physics at Silesian University at Opava. I am interested in relativistic astrophysics, especially in geometry around objects with extremal gravitation like black holes, neutron stars and active galactic nucleuses. My PhD. thesis is pinpointed to the physical processes in space-times with non zero cosmological constant. Within the frame of Public Relations I am interested Marketing Support, in actual trends of PR, in Crisis Comunication and Media Relations. My priority is to be focused on science and research in near future. Since summer 2004 I am interested in development and localization of famous GNU/GPL content management system Mambo (Joomla) under the name "MamboMCZ". This CMS is completly in Czech language only and is completly OpenSource also. All my work is also my hobby. But nevertheless, I have also other hobbies. These are, for example, growing of exotic plants. I am also interseted in self defense and martial arts. I keep black belt in japenese martial art Aikido and partly I am giving some classes in self defense, BJJ and ultimate fighting techniques.
