Much of that I was familiar with - the very end did throw me a curve ball: "Planck’s law doesn’t just stop at the maximum, so nuclear explosions also produce even shorter wavelength radiation, namely gamma rays. This is solely the radiation a nuclear explosion produces because it is hot, as opposed to the radiation it produces because it is nuclear, such as neutron radiation." I have heard that in different ways but I guess I didn't grok it until reading that last sentence in particular. I always love unexpected insights.
