[FRIAM] Newborn Heart Rate

Sat Oct 2 22:14:46 EDT 2021

Brilliant, Eric.  I think I have strong attraction to Platonism.  I had a
thought a few years ago that every right triangle in the plane has the
Pythagorean property regardless of humans or their awareness.  Then I
wondered where a perfect right triangle exists in nature.  My answer to
myself was {(0, 0), (1,0), (0, 1)}.  But that's a "mathematical
confabulation" according to Nick I suppose.

People who haven't studied limits carefully, say elementary calculus
students, think they're mysterious when they aren't.  As you know lim(f(x))
as x goes to 0 just means some number, if it exists, which f(x) approaches
arbitrarily closely as x gets arbitrarily close to zero.  f(0) may or may
not exist.  If Zeno had understood that I don't think he would have felt
there was a paradox.

But I don't know that obviously.
