    Lassen's work, completed two years prior to Appleton and five years prior to Hartree, included a more thorough treatment of collisional plasma; but, published only in German, it has not been widely read in the English speaking world of radio physics. Hartree saw how the differential analyzer could be applied to his work on the electron fields of atoms, and he traveled to MIT in the summer of 1932 to see the machine. He again traveled to MIT in 1933, and this time he used the machine to work on the self-consistent field equations for Mercury.

    RelativisticNonlinearWhistlerWavesinColdMagnetizedPlasmas

    Appleton-Hartree dispersion equation. This equation was originally derived from Lorentz classical equations of motion of electrons in an electromagnetic field. A vast body of literature exists on whistlers and related phe- nomena in at least three areas: space plasmas, laboratory plasmas, and solid state physics. Since it is impossible to referto allthis important work, we shall ... Electromagnetism is perfectly time-symmetric - every possible process has to be possible in the opposite time direction as well. If we invert the process, we have an electron that emits a photon out of nowhere. Clearly that doesn't work in the electron rest frame, and if something does not work in one frame, it cannot work in any frame.
