Ah... I remember these !

My Biology/Ecology Bachelor's degree was at Perpignan, France.
The university there is famous for having a continuous Biological Modelling course that starts in Semester 1, and keeps going all 3 years !

These equations were amongst the things we learned around the end of year 1 / beginning of year 2.

It's an interesting idea, to have the Steemit user ecosystem be represented by such equations in relation to how users are affected by available steem, though it is in my opinion a bit too simplistic.

We'd need to measure the amount of available steem and the number of users throughout the history of Steemit and see if it, indeed, does seem to correlate with this kind of rhythmic cycles.

Though the human component means some will be easily disheartened by the slightest drop in available Steem and others will go follow the "Hold The Door" mentality of never letting go, no matter how little they're rewarded, believing it'll only go upwards from there.

In any case, it's an interesting application of a concept which, to be quite honest, I've half-forgotten how to use XS
