this theory fascinates me because i think it applies both to materials and to people. maybe it applies to the markets as well.
in engineery classes it was called the 'angle of repose'. water for example seeks to be flat, if you pile up sand eventually it will run down the sides and only form a cone with a predictable base to height ratio, if you add water to sand it will pile up at a different angle because of resistance, technically you could configure velcro at almost any angle you want.
when i worked in construction it was called angle of the dangle instead, but the same theory (no offense to ironworkers, but you ain't the brightest bulbs in the socket). when i misspent time on the street the saying was 'you can only stack sh*t so high'.
so this is a universal concept that applies to things and folks, and maybe the markets. i am going to work on this some after i retire and maybe die famous.
