... If we consider a system consisting of several free particles, with H = pi2/2mi, we find in the same way that the transformation qi´ = aiqi + bi(t) is a symmetry of the Hamiltonian. That means that the position-value of each individual particle can be linearly transformed in its own independent wa ...
