HR (Hertzsprung Russell) Diagram - how stars are classified based on magnitude & temperature

In this video I review the HR (or Hertzsprung Russell) Diagram.
Quickly reviewing the concepts of brightness and colour of a star, I show you how we can classify stars and how that leads to better understanding of the nature of stars.
