Tamás Vicsek, physicist and member of HAS, gave a lively and thought-provoking lecture concerning the questions of order and chaos, challenging the frontiers of physics. These topics are relevant as they pose questions we encounter in our everyday life. Order or chaos may be characteristic of atoms or microscopic organisms, but are also terms related to things from our desk to our thoughts, and to the forms of collective human behavior. The most interesting phenomena may be observed on the border of chaos and order. This is where fractals, and other forms of intricate geometry, are born.
