I guess this is the same idea I presented a couple of days ago in this post (which incidentally was also inspired by an Overcoming Bias blogpost):
Overcoming Bias: The Simple Math of Everything
I called it a concept hierarchy of science; and mathematics is nothing else than concepts in relation. (the uninterpreted equations are only meaningless symbols). So, the equation plus the mapping to the relevant concepts in the science would constitute a “core idea” – maybe the Overcoming Bias community has the momentum to start a concept hierarchy?
