Working back..to the start

“The inverse problem here is, given an observed connectivity matrix, to work back to the dynamics that generated it.” (Robert Gregson); love the phrase, though maybe would have started with “The solution here is..” but I’m just being picky. It reminds me of a recent meeting when explaning why the structure of a database and the formation of content on the front of a website are structured differently! Also reminds me that  the word ‘obstruct’ as in ‘Do not obstruct the door’ includes an abbreviated version of the word structure.
