Lagrangian quantum mechanics
TīmeklisOne of the attractive aspects of Lagrangian mechanics is that it can solve systems much easier and quicker than would be by doing the way of Newtonian mechanics. In Newtonian mechanics for example, one must explicitly account for constraints. However, constraints can be bypassed in Lagrangian mechanics. Tīmeklisus quantum mechanics, and thus the digital age. Indeed it has pointed us beyond that as well. The scheme is Lagrangian and Hamiltonian mechanics. Its original …
