Аннотация. Изучение окружающего мира непосредственно сводит к необходимости ведения тех или иных прогнозов, которые сводятся уже к важности установления для них основных законов мироздания, которые можно наблюдать в ходе изучения тех или иных явлений. При этом часто использование физических законов, возможные для описания с использованием не только обычных уравнений, но и дифференциальных уравнений, первого и вторых порядков, в том числе и большого количества уравнений в частных производных, довольно часто используемых при этом исследовании и понимании.

Ключевые слова: дифференциальные уравнений в частных производных, обыкновенные дифференциальные уравнения, математическое моделирование, аналогия, закономерности.

Annotation. The study of the surrounding world directly reduces to the need to make certain forecasts, which are already reduced to the importance of establishing for them the basic laws of the universe, which can be observed during the study of certain phenomena. At the same time, there is often the use of physical laws that are possible to describe using not only ordinary equations, but also differential equations of the first and second orders, including a large number of partial differential equations, quite often used in this study and understanding.

Keywords: partial differential equations, ordinary differential equations, mathematical modeling, analogy, regularities.

Coming to the study of the laws of the world in physical science, certain laws were most often distinguished, the initial ones among which are the mechanical laws created by Newton and developed mathematically from his side, along with other scientists, among whom the figure of Leibniz stands out vividly. For an example of this statement, we can give the differential forms of the basic equations of motion (1), which in turn are reduced to certain values in the formulas of acceleration (2), force (3), work (4), power (5) and others.
