The book “Basics of Mathematical Modeling” by Nikolai Bogolyubov is a fascinating and deep immersion into the world of mathematical models that play a key role in understanding and describing complex processes occurring in nature and society. This work will be a real discovery for students, graduate students, as well as practicing specialists in mathematics, physics, economics and engineering, seeking to expand their knowledge and skills in the field of modeling. In the book, Bogolyubov shares his knowledge and experience, offering readers not just theoretical foundations, but practical examples that will help them better understand how to apply mathematical models in various fields. The author emphasizes that mathematical modeling is not just a set of formulas and equations, but a whole process that includes the analysis, synthesis and interpretation of data. Readers will be able to learn how to formulate tasks, build models, and how to interpret the results obtained in the course of modeling. The book will be of interest to a wide range of readers, including senior students, graduate students, teachers and practitioners . It is suitable for those who are interested in mathematics, physics, engineering, economics and other sciences, where the use of mathematical models to solve real problems is required. If you want to learn how to build models that will help you better understand complex systems, or just want to deepen your knowledge in this area, then “Basics of mathematical modeling” is exactly what you need. The topics raised in the book cover a wide range of issues, ranging from the basic concepts of mathematical modeling to more complex concepts such as dynamic systems, optimization, and numerical methods. Bogolyubov emphasizes the importance of an interdisciplinary approach, emphasizing that successful modeling requires knowledge not only in mathematics, but also in other sciences. This makes the book especially valuable for those who want to develop their skills in research and practice. Nikolai Nikolayevich Bogolyubov's style is distinguished by clarity and accessibility. He knows how to explain complex things in simple language, which makes his books easy to understand, even if you do not have deep knowledge in mathematics. In addition, the author uses many examples from real life, which helps readers to see the practical application of the theory. Other well-known works can also be found in his work, such as Mathematical Physics and Probability Theory, which are also noteworthy and can complement your knowledge. If you are looking for books on mathematical modeling, then you should pay attention to such names as "Mathematical modeling in economics" or "
