In which case does the Hamiltonian $H$ commutes with the momentum $P$?
Can anybody help me? With an example? (No particular or strange Hamiltonians and no particular momenta are involved).
How can I prove that $[H, P] = 0$?
What is stagnation point in fluid mechanics. At the open end of the pitot tube the velocity of the fluid becomes zero.But that should result...
