3D Printed Model of Nuclear Chart
You can see a partial 3D-Dimensional model of the nuclear chart on the right, where the height of the towers represents the mass excess per nucleon. You can find out more about this in a paper published in the IOP Physics Education - Nuclear cartography: patterns in binding energy and subatomic structure.
