 1. Fundamentals of the radiation field: Maxwell’s Equations, vector and scalar potentials, Lorenz Gauge, the electromagnetic stress-energy tensor, covariant formulation of classical electromagnetism.  2. Units  3. fundamentals of radiative transfer  4. continuum processes – radiation from accelerated charges, retarded potentials, radiation reaction, bremsstrahlung emission  5. continuum processes – the Lorentz force, cyclotron and synchrotron radiation  6. continuum processes – Thomson scattering, Compton & inverse Compton scattering (SZ effect as an application)  7. line radiation -- atomic and molecular structure, matrix elements and Einstein coefficients, electric dipole radiation, magnetic dipole and electric quadrupole radiation, selection rules, transition probabilities, thermal equilibrium (Boltzmann equation), statistical equilibrium (applications to HI, CO)  8. ionization equilibrium and the Saha equation
