Presets
The binding energy per nucleon measures how tightly a nucleus is held together, peaking at iron-56. Light nuclei release energy by fusing toward that peak — the power source of stars; heavy nuclei release energy by splitting toward it — the basis of fission reactors and bombs. Iron is the ash where both paths end.

Governing equation
Reading this result: Iron-56 sits at the very peak — the most tightly bound nucleus, where neither fusion nor fission can extract any more energy.
