    An objective, dynamic and physically justified concept of information is elaborated starting from Shannon's concept of entropy and applied to information technology, artificial intelligence (consciousness) and thermodynamics. The justification of an information conservation theorem acquires practical significance in information technology, especially as it moves into the quantum realm (photonics/quantum computing). The unconditional dynamics of information and its objectivity are critically examined and are the foundations of the considerations.We live in the information age, but the concept of information is still not defined objectively and physically. This book defines a dynamic concept of information that results in a conservation of information principle. Just as the principle of conservation of energy is essential to understanding energy, the principle of conservation of information leads to a deeper understanding of information.Information is strongly related to entropy, always in motion, cannot disappear, and is independent of subjects.

    This book discusses Artificial Neural Networks (ANN) and their ability to predict outcomes using deep and shallow learning principles. The author first describes ANN implementation, consisting of at least three layers that must be established together with cells, one of which is input, the other is output, and the third is a hidden (intermediate) layer. For this, the author states, it is necessary to develop an architecture that will not model mathematical rules but only the action and response variables that control the event and the reactions that may occur within it. The book explains the reasons and necessity of each ANN model, considering the similarity to the previous methods and the philosophical - logical rules.
