Dirac's Last Words In Dirac's last paper at the Loyola University symposium, 1984, he upheld one central equation, Heisenberg's equation of motion: ih du/dt = uH - Hu. However, he surmised that all the terms needed to be redefined. The operators should not be simple matrices as they are in QM, and they should not be dependent on simple coordinates. Moreover, the Hamiltonian should NOT be modeled after classical physics. I have the means to pursue this program. Feynman based his path integral approach on a paper of Dirac's on the Lagrangian in QM. This last paper, however, should be regarded as the Vedanta (end, or conclusion, of the Vedas) of Dirac's work. |
