why is the derivative of e^x e^x rather why does e = 2.71.. & not 92.7? what pins it down (depends on choices of axioms?) is the irrational value an artifact of base 10? or it pops out of various geometric series? oh yeah then, just what's the expansion that makes it obvious
this is a self-referential situation where sth is "reproducing" and each "offspring" immediately starts contributing to the process. the bigger it is, the faster it grows. (dollars, rabbits, viruses) there is only ONE "nature" just as 'you' can only be the ONE 'you'.
