I fully agree that tracing each concept to its originating source has great value.
From a presentational point of view, I wonder if it would pollute the plain/clean presentation of the formulas. Perhaps very small footnote-like citations could work, but it has to be unobtrusive.
The hardest part, however, will be coming up with the authoritative source for each concept. As it's outside my field of expertise, we would have to rely on the community to fill in these details incrementally.
