This is the second course in the cosmology series. In this course, we would focus on the important events in the history of the universe. Assuming the universe to be homogenous and isotropic, we would study the following: 1. the relationship between temperature T, time t, the scale factor a, and the redshift z, 2. the relativistic and non-relativistic species present in the universe at a temperature T, or a time t, 3. the number and number density of species as a function of temperature (or time), 4. the energy and energy density of species as a function of temperature, 5. the entropy and entropy density of species as a function of temperature, 6. pressure of species as a function of temperature, 7. the formation of nuclei from protons and neutrons, 8. the formation of atoms from nuclei, 9. the comic microwave background, 10. the cosmic neutrino background, 11. the Boltzmann equation with and without the collision term, 12. the Saha equilibrium, 13. the recombination, and 14. the dark matter.
