Who said this? ... "Biology obviously requires zero math, since
Biology"
Well, you obviously know more history than me, but the point is that
L.v.B's General Systems Theory was all maths and differential
equations, analog stuff not digital, and he WAS a biologist and he DID
work with maths.
And looking at L.v.B's equations, interesting that they are "... Not
Real Systems Theory ...", considering they are pretty much exactly the
same multi-dimensional, differential-equation-base, state-variable
formulation I learned in school, in a course called Systems Theory.
Unbelievably the arguments people make around here.
