Description
Revisit the nuclear energy binding curve, noting that most elements lighter than iron can release energy by fusing together. This is an even more energetic reaction than fission, and it is what powers the sun. Follow the development of fusion weapons and the so-far-unrealized dream of fusion reactors.
