FactChecker replied to the thread Undergrad Is infinity a necessary concept?.There are many uses of "unbounded" N, where f(N)=x will be exact at some unknown large N. That is very different from a convergence that... -

Like.
Perhaps I am missing something, but I am not sure that every occurrence of infinity can be replaced by "without bound". For example... -

Another reason I find infinity fundamental is that, if we want to work with Hilbert spaces of functions, infinity seems unavoidable. A...

Haha.
Chuck Norris did it twice. He failed at his third attempt earlier this year. R.I.P. -
FactChecker replied to the thread Undergrad Is infinity a necessary concept?.If your theory of reality is limited by computer processor speed, you need to think hard about what is real. If that is true, how was...

Informative.
Somewhat off topic to the thread, but just to close the loop on this: in our cosmological models the *observable* universe is finite due... -

I don't understand why is infinity a problem. Sure, it is not intuitive and sometimes it complicates things. But to negate the infinity...

Finitism seems more of an intellectual exercise than an attempt to progress mathematics.

FactChecker replied to the thread Undergrad Is infinity a necessary concept?.No. I think it is part of the "Big Bang" expansion theory. But I will not say more, because I do not know more. I'll leave it to others.

Wow.
Well, we've had about a dozen accounts per year hacked lately where a spammer guesses your password and posts malicious spam under... -
FactChecker replied to the thread Undergrad Is infinity a necessary concept?.I don't. People who know infinitely more than me say it is. But it might be debatable.
