    Research Results to be finished:

    1. Atomic dimensions of surface investigations.

    2. Re-evaluation of strain-stress theory when in front of surfaces.

    3. Adsorption theory of semiconductor as a general theory of general adsorption theory: experimental evidences.

    4. Fermi levels in free particle models.

    5. CP invariance correct in image potential method in electro-magnetism?

    6. Time reversal means zero rest mass in Lorentz invariancy? in density-formulations.

    Some Intuitions:

    We all admit that every theorist is not economic, especially in the management respects. I think that the research necessity in financial part need to have a ‘perfect’ arrangement. The problem is how?

    The rapid changes of statistical viewpoints make every one nervous. A settlement is dispersed needed. Easy way to make every body easier.

    Theorists working in condensed matter branch are themselves theory workers! Special protection must put into act. Otherwise we need to have moved to new department.
