Hamilton's principle and canonical equations of motion

One of the many derivations of the canonical equations of motion is by Hamilton's principle: the canonical equations of motion result by exploring the independent variations of the generalised coordinates delta q and the corresponding generalised moments delta q. In this article the author underlines an objection to this procedure and point out an alternative way forward.
