The book is really interesting. When observing the Universe, we are faced with a dilemma: is there anything beyond matter that lies at the beginning of all creation? Professor Stanisław Zięba proposes that information is something more superior to matter. The author tries to explain the key role of information in the functioning of living organisms by referring to the theory of evolution to which he refers with respect but also with cautious criticism. I have a very positive opinion on the book "The informational dimension of the universe, life and man". This is a clear step in getting to know the universe. Prof. dr hab. Marek Majdan
