| Abstract: | Using the invariance of space-time transformation of Hamiltonian, laws ofconservation of momentum, angular momentum and energy are deduced. It is explained that those three conservation laws are the embodies of space-time symmetry. Therefore, the physicalorigin and nature of these three conservation laws are clarified. |
