"Muh finite numbers in the known universe". This garbage is what happens when a physicist tries to reason in mathematics.

I'm Goldbach and can confirm this.
I originally wrote it as a joke to see if Euler would catch the technicality that invalidated my conjecture.
It got out of hand as Euler took it seriously and started to get famous.

How ? What is there to tell you 2 /\1000 - 1 isn't prime ?

>What is there to tell you 2 /\1000 - 1 isn't prime ?

Do you mean
>2[triangle]1000 - 1
or
>(2 to the power of 1000) - 1
?

We know 2^1000 - 1 isn't prime because we checked, and it isn't.

Wildberger believes that 2[triangle]1000 - 1 can't be prime because according to him, *it isn't a number* - he thinks that numbers only exist if you write them down, and so any number bigger than about 10^10^10^10 doesn't exist because the Universe isn't big enough to contain it fully written out.

>> No.9902368

>>9902356
But isn't 2[triangle]1000 -1 a way to write the number down ?

It's like saying 10 is the biggest number because you can't use your fingers to count higher than 10.

>> No.9902436

>>9902368
His point is that these numbers are exceptions. You can write down certain gigantic numbers like 10^10^10^10^10... easily, but the vast majority of the numbers between 0 and said numbers you will never be able to express.

No, it's not that. It's that Wildberger doesn't think a number really "counts" unless you could literally construct it the hard way, by starting at 0 and adding 1 until you get there. ("could" being a bit ... logically fuzzy in that sentence. Ultrafinitism isn't really defined in any mathematically rigorous way.)

>> No.9903329

>>9902449
Can't you come up with a new numerical system in which it becomes possible to write the number down ?

For example, suppose every chinese character in existence were to stand for a number. Since there are 50 000 characters, you'd be able to write any number from 0 to 50 000 in one symbol, and with n symbols you can write a number up to 50 000^n, I'm not bother doing the math but it's probably enough to represent 10^10^10^10 in our Universe.

You could probably represent a number as an arrangement of symbols in 3d space and save space that way.

>> No.9903375

>>9903329
But the question is not one of representing numbers in some fashion but working with them. It doesn't matter how we write down "large" numbers, we'll never factor them for instance.

To consider them to be the one and the same is the only reasonable perspective.
