In the modern world, the importance of physics is extremely great. Everything that distinguishes modern society from the society of past centuries, has emerged as a result of the application of physical discoveries in practice. So, research in the field of electromagnetism led to the appearance of telephones and later mobile phones, the discovery in thermodynamics allowed to create a car, the development of electronics led to the emergence of computers. The development of photonics can provide an opportunity to create fundamentally new photon computers and other photonic technology that will replace the existing electronic equipment. The development of gas dynamics led to the appearance of aircraft and helicopters.
