I was reading this question - Why is the nucleus of an Iron atom so stable?
There are two good answers. One explains in words, in a way that might be satisfying to those who have been wondering and come upon the question. The other shows the math in enough detail that one can work the numbers and grind it out. That too would be of interest to some who come upon the question.
It doesn't matter which kind of answer the OP sought; the value of a SE site like this is answering questions of visitors who come along after and find it's already been asked. Some visitors will seek qualitative word answers, just wanting to know the essential point and are perhaps not themselves physicsts, while other visitors will be hungry for the serious math .
Just fantasizing... Could both of these good answers get the hallowed green checkmark? Or different colored checkmarks, say blue for the best mathematically detailed answer and orange for the best qualitative words only question? Would that make sense for more than just a few questions?
