The basic genetic code of all cities without distinction, much the same as the double-helix of DNA made up of combinations of 4 elements is typical of all that lives on the Earth, is a concentration process. Gravity, all the attractive forces, attractiveness, catchment and commuting, but also human desire and human interest are just different names for the same fundamental process inscribed in the innermost nature of our world (Clegg 2012, Hudeček 2010, Hudeček et al. 2011). And, on the other hand, the opposite of concentration - "thinning" in the sphere of the universe of expansion and cooling, in the places of prevailing gravity and curvature of space-time, as a result of the course of time the common duration in hours, days, years or even millennia. Two opposites, but at the same time eternal companions are the cause of all diversity as well as, on the other hand, the cause of the interesting similarity in the reality of the existing structures Chardin 2003, Veverka 2013).EnglishopenAccessPlanning in post-communist city: by flexible planning to natural growth and developmentconferenceObject2751-2761
