Even the simplest dynamical systems described by differential equations sets are pain in the neck to solve. In practice to find a solution they use one of the iteration methods which implies the solution is never exact.
Another problem is that the universe is too imperfect for the perfect mathematical models we could build. Because of this, physicists will always have their jobs, even after all mathematical problems are solved
