In the plot, the mathematical problem to be solved by the protagonist is one of the "Millennium problems"-N-S equation. This article doesn't talk about movies, just this math problem. )
The full name of N-S equation is "Naville-Stokes equation". The original form was put forward by Naville in 1827. After development, the final form was put forward by Stokes in 1845.
This equation describes the motion mode of viscous incompressible fluid, which is of great significance in physics.
This equation can be used to describe the flow of tap water in pipes, flight dynamics, and even large-scale galaxy motion in astronomy.
But the N-S equation is an extremely complicated partial differential equation.
If you don't know what a partial differential equation is, please think about it. The solution of the unary equation is a fixed value. But the solution of partial differential equation is indefinite equation, which can be multivariate indefinite equation or even transcendental equation.
It is very difficult to solve the N-S equation. At present, only some parameters and initial conditions can be simplified to get the solution under special conditions. Or in some cases, the approximate value is solved by computer.
At present, no one can give the general solution of the N-S equation, and no one even knows whether there is a general solution.
In 2000, the Clay Institute of Mathematics in the United States listed seven Millennium problems, each of which was solved first, and a prize of one million dollars was provided. N-S equation was one of them.
Using different mathematical tools, we can get different forms of N-S equations. The mathematical form described by partial differential equation is:
How's it going?
Are you stupid after reading it?
It seems that this million is still hard to earn!
I don't know readers, is there an easier way than making this million?
If so, remember to bring Bian Xiao! If not, remember to pay attention to us-Abe Smith!
