And vice versa - because time moves from past to future, we become older. So we can't help but judging about the flow of time from a position which is rooted in time. None of the basic principles and laws of classical or quantum physics indicate any basis for the common belief that time flows only in one direction - the physical laws work equally well in both temporal directions. Now' is dependent on an observer's point of view in much the same way that 'here' is. But the majority of scientists and philosophers continue to describe phenomena in terms of the direction of time of commonsense experience, as if all causal influences exist and act only in that strongly linear direction.
Fractals are similar structures - they demonstrate their similarity at different scale levels.
Life events do not exactly repeat themselves, they are similar. When we speak about time reversibility, we apply the approach of fractals - while saying that history repeats itself, we emphasise similarities in the events occurring at different levels of time dimension of social complexity. The fractal approach helps us to map the scenarios of the living systems. These scenarios reveal chaotic attractors of systems' behaviour. As far as the structure of chaotic attractor is fractal, when we see what changes are likely to manifest at one level of its structure, the approach of fractals helps us to construct a picture or a map of what is likely to occur at another level.
