IAS Fellow's Public Lecture - Principles of conservative evolution or the boundaries of our freedom

15th November 2018, 17:30 to 18:30, Sir James Knott Hall, Trevelyan College, Professor Boris Snopok (Institute of Semiconductor Physics, National Academy of Sciences of Ukraine)


Can a "complex system" be of any kind, or are the processes of its "vital activity" coordinated in space and time? Is it possible to change one thing in it, without losing or changing everything else? In some form or another, these questions are actively discussed in almost every field of human activity. The answer to them allows us to understand where we are going and what path we are following. It is the analysis of this evolution that allows us to understand what we are actually dealing with. The integrity of the system determines its individuality - a combination of processes that the system "selects" from the range of possible ones is unique, but not arbitrary; only certain relations between the possible processes allow the system to develop as a single whole. In this lecture, Professor Snopok considers one of the most general models of the evolution of complex systems having simple analytic form, expressed in a stretched exponential function. This function describes a huge variety of processes in the world around us. Using simple physical models as an example, it will be highlighted that a “causative factor” (causa efficiens) specific for a complex system is a result of the dynamic coherence of intrasystem processes. Finally, this will answer the question: Is it necessary to "hurry to live" in a uniform "crowd" or does the possibility of a "second chance" in the environment of “experienced rivals” open the way to a "long life" .... at least for point-like particles?

This lecture is free and open to all.
