Navier-Stokes equations

Mathematically, the motion of a fluid is described by the so-called Navier-Stokes equations. In the spirit of Newtonian mechanics, these equations should determine the future motion of the fluid out of its initial state.

Old mathematical challenges

The aim of this article is to highlight some previous challenges that were also a stimulus to finding proof for some interesting results. With this pretext, we present three moments in the history of mathematics that were important for the development of new lines of research.

The Hodge conjecture

The Hodge conjecture, proposed in 1950, is one of the seven millennium problems, and is framed within differential geometry and algebraic geometry.

Absolute truth exists

Each domain of knowledge has its own language, content and method. They give it character, and whenever a field of knowledge advances, it is thanks to one of them. Language is very important for science, but is not necessarily a priority. Old language can lead
