Status of the three-body problem

Although there is no solution for the general three body problem there are many related results, especially for the restricted case. Here is a study of LE's in restricted 3BP. And here is a ...

Euler's Master's Thesis

As Franz says, it is impossible to know for definite which view the young Euler supported. However, Newton had already disposed of the Cartesian vortex theory in the Principia which was published ...

restricted three body problem equations of motion using particle distances and one angle variable

The equations of motion cannot be written as $$ \ddot{r}_{ij} = f_{ij}(r_{12},\ldots, r_{n-1,n}, \dot{r}_{12},\ldots, \dot{r}_{n-1,n}) $$ Consider $n$ equally massive particles arranged equidistantly ...
