I was studying theoretical physics at the Charles university in Prague. I am interested in quantum gravity and cosmology. Other my activity is playing the piano. I regularly give concerts. My favourite authors are S. Rachmaninoff, A. Scriabin and J. S. Bach. You could find more informations at www.classicalprague.cz or hraniprohrani.cz. View all posts by johnynew
