comment Evolution in the interpretation of the Dirac equation
I meant "wave equation" to mean "not a field equation". I'll have a look at your references, thanks.

comment Material resistency to lasers beam
So it's not the duty cycle but the peak power. Duty cycle is "time on" over "total time".

comment Mathematica to help for an Hamiltonian problem
Thanks, it is not exactly what I was looking for but it might do the trick. About the tags: these two can be made synonyms.

It doesn't burn.

comment Why doesn't the bike fall if going with a high speed?
@Adrian: you are saying "inertia" because... there is no force... In the case of the rope, the rope is providing a centripetal force.

comment Why doesn't the bike fall if going with a high speed?
just to be a bit provocative: You are standing upright on your bike, you violently lean on one side, just at the beginning what is the direction of the centrifugal force ?

comment Why doesn't the bike fall if going with a high speed?
Then you should thought of reading wikipedia in more details. And this: "you get centrifugal force (as oneat correctly pointed out)" is in no way true: imagine yourself in the inertial frame moving with the bike: no speed, so what ? @Davis answer is short but correct.

comment Why doesn't the bike fall if going with a high speed?
This is a very misleading answer: there is no "centrifugal force", just a centrifugal pseudo-force in a rotating frame. When you look at a bike you generally do not consider a rotating frame, and even if you do, how would you relate the rotational speed of the frame, leading to a centrifugal term to the speed of the bike ?

comment Why do we automatically assume that the velocity vector $\vec{v}$ and location vector $\vec{r}$ are independent?
And think about real cases as in the first part of my answer. You can then easily deduce if v is independent of x or not.

comment Why do we automatically assume that the velocity vector $\vec{v}$ and location vector $\vec{r}$ are independent?
Just forget about all these things about the link between v and x. I think there is a big confusion about all this in your question. Start from the basics and try to understand the second part of my answer.

Solution to a three-body problem exist when the three bodies are aligned as in your example.
