what is the most useless number?

probably pi. Every useful use of pi is 2pi.

That quest will probably fail, either due to semantics of "useless" or due to

I like the tau meme because it makes it much easier to identify pop-sci idiots like you.

>>7811771
I'm thinking they are all equally useless.
But if I had to pick one I'd say 1.
Cause we can always use 0.9999... instead.

>>7811771
I'm thinking all we need are zeroes and ones.
I don't care about the rest as long as we can use binary.

>>7811771
There is no useless number. I'll prove it:

Suppose there were a useless number. Let N be the least useless number. Then N is useful because it is the greatest number such that all n < N are useful (which is a pretty useful property). Contradiction.

Therefore no number is useless.

[math]\displaystyle -\frac{1}{12}[/math]

>>7813697
>(which is a pretty useful property)
This has yet to be shown.

>>7813707
N is useful because it is the least example of a useless number, which is useful in demonstrating a useless number. But then N is useful, contradiction.

[math]\displaystyle 1 \approx 2 [/math]

>>7813717
There is no use in demonstrating the existence of a useless number, by definition. Your "proof" does not work.

>>7813721
Suppose that one wanted to come up with a list of all useful numbers. This would be a useful list.

N is useful in constructing this list.

i is pretty useful; it isn't even real.

0 isn't even a real number

You are confusing digit significance for numbers.

nobody noticed because you didn't use >>

has there EVER been any use of a number 820047519743129000023284899902127174 prior to posting this?

>>7813850
Would you rather your post be numbered as MMMMMMMDCCCXMMMDCCCL

>>7814939

>>7813697
Not bad.

You cannot post the most useless number in this thread, cause if you did, this number would have been useful for this context.

That would be [math]\mathrm i[/math], because its only use in physics is simplifying the study of signals, and simplifying something is not useful.

>>7813850
I'm pretty certain that 0 ∈ R

>>7815175
I'd like to see you try doing quantum physics without it.

how aboot

[eqn]\alpha\left|\begin{bmatrix}
[0\,1]\\ [1\,0]

\end{bmatrix}\right>[/eqn]

nobody needs imaginary numbers. they're stupid.

>>7813697
The proof should go as follows.

First, 1 is a useful number as it is the multiplicative identity. Now any number [math]n[/math] is the unique number such that [math](n+1)-n=1[/math], i.e. transforms the number [math]n+1[/math] into a useful number. Therefore [math]n[/math] is itself useful.

>>7815221
it's even more stupid not using them. also we are better off using them.

also there is nothing "magical" about imaginary numbers. they are tools just like other variables are.

>>7811771
>what is the most useless number?

Any number other than 1,2,3,4...

Let's say you get a flat tire, a lug wrench would be a useful thing to have.

0 lug wrenches means you never bought one

-1,-2... lug wrenches means you had 1,2...in your trunk but either you lost them or somebody stole them

Any rational or real number like 273/44 or 2^1.2 means you have a bunch of wrenches but they're shattered and bits fell off and you lost the bits

Complex wrenches wouldn't be useful because even if you had one part of it would be in another dimension and you wouldn't be able to loosen the lug nuts since you only have like, half a wrench

>>7815229
Induction sucks.

>>7815245
I wasn't proving any numbers are important.

>>7815251
I don't think you know what induction is.

>>7815237

what's stupid about imaginary numbers is that when your dimensions run out of letters in the alphabet, nobody knows what the fuck they're supposed to do.

it's like wondering what happens when you plug more than 26 drives into a windows computer.

>>7815263
>I don't think you know what induction is.

it's what makes optimus prime work

>>7813697
But you haven't shown that there is a least useless number.

>>7815288
Literally just start numbering them. e1, e2, ...

>>7815406
that's literally what you learn in any linear algebra course. don't get what his problem is

>>7815406
>>7815412

why label something when you can simply write it into an ordered list?

you're doing math, not playing battleships ffs.

>>7815437
Yeah, I have no idea why anyone ever uses numbers, anon. They're so inefficient.

>>7815321
The natural numbers are well-ordered, so if there is a useless number, there is a least useless number.

>>7815545
Every set can be well-ordered, anon. We don't have to restrict ourselves to the naturals.
