From fluid mechanics backgrounds to modern field theory

Our presentation keeps a historical line of reasoning, since we start from old concepts of fluid mechanics and finish on concepts of modern field theory. We want to show that some facts from the nature phenomena, which have firstly been discovered on the ground of fluid mechanics, were next incorporated into physics and later become the important pattern for whole mathematical physics. Especially, well-known continuum models, which have firstly been found in fluid mechanics, next became the key patterns in theoretical astronomy, electrodynamics, string theory, etc. Technically, it was possible, since in the 18th-century, many researchers, like Newton, Wallis, Euler, Clairaut, Lagrange, have developed fluid mechanics simultaneously with whole physics, therefore fluid mechanics analytical tools, step by step, become the whole physic ones. In other words, fluid mechanics played a leading role in those days and undoubtedly formed the basis for the development of many leading areas of physics.
