comment Do Lagrangian points actually maintain a fixed distance?
So, in the three body problem, the orbits more closely resemble circles than ellipses? And if so, is the speed relatively constant so that the difference in distance between the third and second body is negligible?

comment Expression for the (relativistic) mass of the photon
It seems that in my book there has been a misprint, as the mass got rendered as $h\nu c^{-3}$ instead of $h\nu c^{-2}$. In that case I see how they deduced that.
