Very cool

Excellent graphics, great learning aid, and the explosions are fun!

Why put nonsense games on your phone for your kids, when you can put this app & Star Chart on it & add some inadvertent education when they get their screen time?

With modern tech offering so many options to consume your time (and money) with nothing to show for it but the passage of time, its really satisfying when your elementary-age kid comes up to you & asks for your phone to play Nuclear or Star Chart, especially when other electronic gaming options are around for them. (on Moms phone, even)

Future enhancements to think about:
• have the decay "explosions" reflect some relative, approximate amount of binding energy released. (Currently all decays look pretty much the same.)
• I dont know how this works, but presently you can add electrons to an isotope until the cows come home (or until it decays.)
• I think it would be interesting to see some indication of effort needed to add each additional partial. (Ideally, the user would have to >exert< a relative amount of energy appropriate & proportionate to the addition, but I have no idea how this could be implemented.). For an indication of energy consumed to add a particulate, Id suggest some spectrum/thermometer bar indicator deftly harmonized into the display.
