Time in quantum mechanics
... Why did Heisenberg present the ‘same’ formula (0.4) in two different guises? In classical mechanics the time parameter is sometimes turned into an internal dynamical variable conjugate to (minus) the Hamiltonian of the system. Heisenberg may have had this in mind in connection with the first equatio ...
