This is the 2D counterpart to the 3D binding-energy curve simulator. It evaluates the same Bethe–Weizsäcker semi-empirical mass formula independently here, but instead of an orbiting 3D scene it gives you a flat, click-driven B/A-vs-A curve seeded with real notable isotopes (from hydrogen-1 to uranium-238) and a genuine fusion/fission energy-release calculator that reads actual B/A values off the curve for each reaction to compute the real MeV released — the same arithmetic used to explain why fusing light nuclei or splitting heavy ones both release energy, and why iron-56 and nickel-62 sit at the top of the curve where neither is possible.
