Learning Objectives

1. Understand the fundamental forces of gravity, electromagnetism, and the nuclear force, and their interplay on large and small size scales.

2. Visualize the fission process.
   1. Comprehend how the fusion process acts to divide unstable (radioactive) nuclei.
   2. Connect the difference in mass between the initial reactants and the final products to the energy emitted.
   3. Evaluate the importance of fusion within the Sun by considering the amount of available radioactive materials in the core.

3. Visualize the fusion process.
   1. Relate the temperature and pressure within the solar core to the probability that two protons can join (fuse).
   2. Connect the mass lost in the fusion process to the emission of energetic gamma rays.
   3. Quantify the amount of hydrogen which must undergo fusion every second in order to power the luminosity of the Sun.
