Summary

1. Ideal fluid equations. Sound.
2. Bernoulli equation. Steady spherical flows: Bondi accretion and solar wind.
3. Instabilities: Jeans, thermal, Rayleigh-Taylor, Kelvin-Helmholtz
4. Turbulence and convection. Mixing length theory. Disk accretion.
5. Shock waves. Sedov-Taylor-von Neumann solution. Supernovae explosions.
6. Particle acceleration at shock waves.
7. Cosmological expansion. Dark matter and dark energy.
8. Early universe: inflation, quantum fluctuations, baryogenesis
9. Thermal history of the Universe: cosmological nucleosynthesis, decoupling of the matter and radiation, cosmic microwave background.
10. Evolution of cosmological perturbations and origin of galaxies.
