Heisenberg’s uncertainty principle states that we cannot determine the position and momentum of a particle at a time. I think I have an idea to prove it wrong ( although I believe I must be wrong here) :
Taking two electrons,, $e_1$ and $e_2$ in motion, we can determine the precise position of $e_1$ and the precise momentum of $e_2$.
Since we know that the momentum of both electrons is mathematically related to each other, we could conclude that the precise momentum that we measured of $e_2$ is the same as that of $e_1$. Hence the position and momentum of $e_1$ is determined at the same time.
