Techno aids words; Time-passing, body measurements, Testosterone ... WARs--thence normalized -vs- then-Population, etc. Hint: WW-II was a piker compared with the Mongol hordes. And like that, Old-time tortures illustrated: Drump's immanent-Cruelty is merely the lo-IQ-version, as in similar brutes-with long-faces (yan correlation in the blender).
It's bloody n! It's got Scale & Relativity you can only try-for [there are no algorithms for That feat].

Tune-in for ~20 min and ya won't need to switch to transistorized guitars ..as palate cleanser or mind-gag.
One line ... "data can only tell you so much.." So Pedagogy has advanced --- this as good an exhibition as I've seen in decades, kinda Edward Tufte writ Large in 4-D and skipping all aspects of the Corporate-speak which has morphed on down to daily-affairs-in-small-places {and related atrocities)

(Whatever happened to our use of 'nomographs'??)
John Scott Campbell was a wizard of such useful examples: One: you could just memorize a brief formula; drive car at at (say) 55 mph--put in neutral--note time to hit 45; fill in 'kilopounds' IIRC for mass; the wind coefficient is the implicit McGuffin:
Result is HP needed at Vel=V, here 50 mph; [use (V+5 mph) time --> drop (V-5 mph)]. Be surprised at how little 'HP' is needed at 50 mph; then try 100. Cheap thrills. (Yeah: worked on Black Shadows too; try sitting up then prone). J.S.C was a multiplied mini-Feynman: only magnified beyond some physics specialty-Boutique. But I digress.

HP= [1.21 M ● V]/T ... using the ∆-mph V+5 --> V-5
