Research and Professional Activities

I have done research in many different areas over the years and remain fairly unspecialized. I am interested in all areas of science but a main theme has been to improve the clarity and conceptual simplicity of our understanding of some areas of physics and theoretical chemistry. Here is a list of topics:

  • Theoretical chemistry: The Born-Oppenheimer separation, Vibration-Rotation coupling,
    Electronic structure theory, Hund's rules, The Thomas-Fermi approximation, the Periodic
  • General relativity: Scalar gauge theory of GR, Curvature, Kaluza-Klein ideas.
  • Classical mechanics: Non-holonomic dynamics, Angular velocity, Rotation of non-rigid
    systems, Separability.
  • Electromagnetic theory: The nature of magnetism, The Darwin Hamiltonian with
    applications to plasmas and superconductivity.
  • Pedagogical and popular accounts of physics.


Please note that this list might not be complete. Follow each article link for additional authors.
