Demonstration that stars are the most powerful freezers in the universe! In this video I calculate the entropy at the start of a star's life (main sequence phase) and the end of it's life, before core collapse supernova.

This video covers:
Neutrino production in the stellar core.
Entropy per baryon at the start and end of a star's life.
