The ratio of random and natural in physical discoveries

The article deals with the issue of the ratio of random to natural in the process of scientific discoveries. In the curricula of professional training of bachelors and specialists, except for the students of humanitarian profiles, physics is included as a mandatory discipline, in this regard, the results presented in the article will be interesting to students as cognitive, and teachers as educational and methodological. Specific examples from the history of the discovery of physical laws and phenomena show that random and natural when these laws are discovered are closely related, which is typical of different fields of natural science. Discoveries considered as random are almost always naturally justified, and in natural discoveries, it is impossible to completely exclude the factor of the random. The dialectical method of estimating the ratio of random to natural provides organic penetration of elements of random in natural-historical patterns of science development.
