Re: My 3 body simulations in 4 dimensions

I edited the moon simulation, and here are some pictures from the newer moon simulation

Re: My 3 body simulations in 4 dimensions

I think it would be cool if it was possible to have a similar simulation on the GSim of this site.

My 3 body simulations in 4 dimensions

I created 2 3 body simulations in excel, in which the forces depend on charges instead of mass, and with the force law Y2(r)/r with Y2(r) being a Bessel function of the second kind.

Re: Rung Kutta 4 in more than 1 dimension of space

Nevermind, it seems I had the correct formula and the inaccuracies must have been from careless mistakes.

Re: Rung Kutta 4 in more than 1 dimension of space

I tried changing the time step to 0.3 Polynomial.png and found that with the polynomial method the x value doesn't even complete 1 cycle before rushing towards negative infinity Rung Kutta.png However for the Rung Kutta 4 method the amplitude is nearly the same as it was at the beginning implying th...

Rung Kutta 4 in more than 1 dimension of space

I understand that for one dimension of space a Rung Kutta 4 Formula for approximating the equations of motion given some force that depends only on the location of an object is k1xn=vn k2xn=vn+h*k1vn/2 k3xn=vn+h*k2vn/2 k4xn=vn+h*k3vn xn+1=xn+h/6(k1xn+2*k2xn+2*k3xn+k4xn) k1vn=f(xn)=acceleration k2vn=...

Two Body Problem for different Force Laws

I understand that the two body problem is solvable, for any two bodies using the inverse square law, and it is also solvable for the reciprocal law. I understand that the three body problem is not in general solvable, although there are some special cases of the three body problem that are solvable....

Determining, which electrically charged fluids will sink on an electrically charged sphere?

There is an electrically charged sphere with a significant electrical charge, and in which the mass and radius are such that the gravitational acceleration from the sphere is negligible. Also any tidal forces on the sphere are negligible and the sphere is in a near inertial if not an inertial refere...
