What is nuclear fusion and what doe sit generate energy? Where does the energy from the sun come from? This video answers both questions as it reviews how hydrogen fuses to form helium and generate lots of energy.
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.
What hold a nucleus together? Why does it not just fall apart. In this video I discuss the Strong Nuclear Force, in simple terms that holds the atom together. This concept is essential to explain radioactive decay, fission and fusion.
