Brief thoughts

Brief thoughts Evolution of the Universe cannot be described as simply as theories about the Big Bang initially described. In a presentation the lecturer presented the evolution of the Universe as chain of accelerating or slowing expansions. The exponential and logarithmic expansions of the Universe are very reminiscent of the quantitative and qualitative changes. The question arises, what does the Universe feed on if an evolutionary process is going on in the Universe?

Thoughts while reading a book In my first approach, the system definition is as follows: - The system has elements which can be separated from each other. - The system has a structure i.e. there are a lot of links between components of the system. - The structure of the system - that is, the network of links between its components – is quite complex. - The system is open in a physical sense i.e. the system has a special behavior with his environment. - Behavior of a system is consistent i.e. a given input of environment triggers the same or at least similar output off the system.
