Even “e” and “pi” would have been noncomputable at one point in time.

But the noncomputable numbers make me wonder if our notion of mathematics is too general/powerful.



We call a real number computable if there is an algorithm that can compute it to arbitrarily high precision. So e and pi have always been computable.


I think in this case it's Reals that are too general. What is the virtue of these uncomputable numbers? If we can't compute/express them then what can we do with them?


Was pi ever really uncomputable? You can draw a really big circle and measure it in multiple ways.

And when e was defined as a symbol, it was with a computation, (1 + 1/n)^n
