There are numerous symmetries around us and sensation of beauty is linked to symmetries. Zakoni očuvanja u fizici posljedica su  simetrija prostora i vremena.  There are also symmetries in abstarct space of mathematics one of such simmetries  called gauge symmetriy is underlying principle used in physics to find out the laws govering the world of the elementary particles.  In short, one could say that equautions which  we used to describe the  process in nature should be writen ina  away to be free of any convenction introduced by human beings.
