I found the answer: In this link https://github.com/fding/nbody (Newtonian mechanics and a four-order symplectic Candy-Rozmus integration), there is c++ code and phyton. I've modify the c++, so now I calc the inital positions and speeds with cspice and pass then to Newton candy with other...

Hello, I've made a SPK file for asteroid 7482 (1994 PC1) with Horizon. I wan't to change the initial velocity with cspice, because I want to know where it will be in a future time at the speed changed. (now I'm using Newtons calc but is slow an error increases with time). This is for calculating...

Solving 1D Dirac equation there are 2 matrixs, and from those we get the space probability and current. If that current reflects the spin state, could happen than the EM fields from the matter acting as potentials, drives the spin to up or down, and when it reaches the north os south pole in...

After computind dirac 1D equation time dependent for a free particle particle I get 2 matrixs. From both,them I extract: 1) the probability matrix P =ps1 * ps1 + psi2 *psi2 2) the current matrix J = np.conj(psi1)*psi2+np.conj(psi2)*psi1 I think that current is related to electricity, and...
