Speaking as a mathematician, no. We have the Navier-Stokes equations, which we are fairly certain are a good model and which work well in practice/numerically.

Speaking as a mathematician, no. We have the Navier-Stokes equations, which we are fairly certain are a good model and which work well in practice/numerically. So an engineer might agree with your view. However, mathematically these equations are difficult, we have very few explicit solutions and the question of whether solutions to these equations are well-behaved in all circumstances is a famous open problem. Indeed, it is one of the Millenium problems and solving it will make you very famous. Also, your "I'll let the article speak for itself" is rude and naive.
