1. It contains all others, and transcend them.

e obviously.

<div class="math"> \frac{d}{dx}(e^x)=e^x </div>

You don't get that anywhere else.

>>5037514
Derivative of 0 is 0?

73.
It's the 21st prime number, its mirror, 37, is the 12th and 12's mirror, 21, is 7 x 3.
also, 73 in binary is a palyndrome. 1001001.

Euler's Identity, -1.

it's just fucking sexy.

I've always had a thing for ∞.
It's like 8 but seems more surreal.

0.
I could stick my dick in that.

>>5037518

0 is not really a number kiddo

>>5037505

1 is the loneliest number

pleb choice: pi
pretentious choice: 0, e, negative numbers
right choice: 17

>>5037569
let the man dream, it's only a placeholder.

>>5037505
I like 7, it's the largest single-digit prime.

>>5037514
that's not a characteristic of the number but of the exponential function, i.e. is the same for 2^x, 5^x, n^x etc.

You dumbass.

>>5037580

Size is not everything.

Closest thing to tits anyone on this board has ever gotten.

>>5037558
Infinity is not a number; it's a concept.
It represents an unbounded limit

11

>>5037582
sorry but the derivative of a^x is equal to: (a^x)(ln(a))

>>5037582

How's that high school education treating you?

>>5037673

i always liked e

i have nothing but scorn for pi, and the golden ratio.

the square root of -1 sucks too.

e is the number to rule them all

2

2 is a pretty cool guy.
2+2 = 2*2 = 2^2 = 2 (tetrated with itself) = 2 (pentated) etc. etc.

5037711 is the most superior number.

>>5037711

how did you do that?

ARE YOU ONE OF THEM TOO??? GET BACK IN THAT OTHER THREAD!!!

0 and 1 mofo

>>5037726

0 is still not a number

>>5037726

of course 0 is a number. it is an integer, the one between -1 and 1.

>>5037758

It's a placeholder.

>>5037754
Define number.

>>5037763

Okay a number must fulfill:

<div class="math"> \frac{1}{n}=[defined value] </div>

On 0:
Excerpt from the wolfram definition: The word "number" is a general term which refers to a member of a (possibly ordered) set.
>>http://www.wolframalpha.com/input/?i=Number&a=*C.Number-_*MathWorld-

0 is a member of the set of integers, therefore it is a number. It may have no value, but it still qualifies as a number.

>>5037763
>>5037761

i suppose by some arbitrary definition you can believe that zero is not a number.

but it is a number that you have to have to count from -3 to +3. it is the number of things you have when you do not have any.

zero is a number. pluto may or may not be a planet, but zero is as much a number as any.

>People saying 0 isn't a number

>>5037773

>it is the number of things you have when you do not have any.

It's a placeholder that represents that of not having any of something.

You can't count to zero.

>>5037786

i'm glad you don't work at mission control.

>>5037786
For something to be a placeholder there must be a necessity of something else to be there for it to be a placeholder for. 0 is a number, because theres not some mythical figure that can be there in place of it.

>>5037786
Count - v - name or recite the numbers in ascending order

>You can't count to zero because zero is not a number therefore zero isn't a number.

>>5037792
If 0 is not a number what is between -1 and 1

>>5037780
^this

Does /sci/ even into Peano?

Don't know, OP. But I like 7.

>>5037711
wait...what?!

>>5037811
The slow board effect.

>>5037673
well, brah

>>5037593
Never taken projective geometry, eh?

3 is the first uneven prime.

Get on my level.

ctrl + f 42

One anon at least is on the right track

Here's a list of my favorite numbers, in no particular order.

>1
It's overrated, overused and given undue significance by many in a society of competition which rejects intellectual collaboration. But it's still the basic concept from which grew all of mathamatics in its complexity and (sometimes) splendor.

>2,4,8
The first powers of 2 are the whole numbers which appear most naturally in all the equations governing dynamics of systems in our homely three spacial dimensions.

>e, <span class="math"> \pi [/spoiler], <span class="math"> \phi [/spoiler]
For obvious reasons, these are the most important and awe-inspiring real numbers, appearing naturally in every surprising corner of mathematics and physics.

>i
A beautiful reduction of methods from higher algebra to a formalism that every young mathematician can intuit and enjoy, with seemly endless applicability.

Phi, the golden ratio.

23.
If you say anything else, you're wrong.

Tau is a great number because fuck 2π.

1 is the loneliest number that you'll ever know.

2 can be as bad as one. It's the loneliest number since the number 1.

>>5038003
This.
It's even in the Mandelbrot set, for fuck's sake.

27

its also following me everywhere

>>5037580
I don't like judging numbers for their "digit characteristics", remember the decimal system is not the only one. 7 has 3 digits in binary, and 2 in ternary. "largest single digit prime" is not too accurate.

Phi, is clearly the best. e is cool too.

not to be too mainstream, but e and pi are both nice and combine in lots of pretty ways. like
<div class="math">\int_{-\infty }^{\infty } e^{-t^2}dt=\sqrt{x}</div>

>>5038308
x = pi

>>5038308
fuck that should be sqrt(pi) on the right

>>5038158
liking numbers in the first place is pretty retarded I must admit so why go off on a tangent?

>>5038308

$Log(-1) = i\pi$

$e^{i\pi} = -1$

>>5037514
what about 10^x?

>>5038354

55 57

yes we're fucking aspies suck my dick

When I was a kid, I thought 7 was the coolest number to draw. It's kind of slanty and raked, with the sharp turn at the top corner.

Thinking about it just now, 8 reminds me of a woman's breasts and hips in the ideal proportion.

Hmm. What was the question, again?

>>5037514
Also

<span class="math">\frac{\pi (x)}{x} ~ \frac{1}{\log_e (x)}[/spoiler]

>>5038419
There should be a "~" between those. i.e. the percentage of prime numbers under x is approximately 1 / log_e x.

>>5037505

Pi

>>5037700
I FUCKING LOVE YOU
although I use that logic to reach the conclusion that 4 is the best number

>>5040235
see >>5038063

I know its not a number but damn is a capital gamma cool. The function Γ(n) is cool too

>>5037804
I was gonna say that but that is not a number

All Integers are numbers
All Natural Numbers are numbers
0 is an element of the set of Non-Negative Integers as well as the Natural Numbers.

0 is a number.

Now stfu.

>>5040558

Not only is 0 a number, but it is the number in which we use to prove the existence of all numbers by induction.

>>5040636
>proving the existence of numbers instead of taking them as an axiom

Pleb, go learn some set theory.

The idea that there are distinct numbers is the worst lie in history.

Either .9999....... or 1

I can't decide.

>>5040951
you are the pleb

>>5040974
http://en.wikipedia.org/wiki/Zermelo%E2%80%93Fraenkel_set_theory#7._Axiom_of_infinity

7 of course

because single digit, prime and (1/7) has the longest

and it is the largest principal quantum number

7th heaven, 7th density, all that is (and is not)

>>5040636
>induction
lel
He thinks there is place for induction in math. Go be sloppy in your shitty sciences.

>decimal numbers
you people disgust me

8
it is the only natural number that is perfectly symmetrical both vertically and horizontally
symmetry is perfection
and perfection is obviously the best

>>5040985
Go take a discrete or mathematical proofs class, pleb.

2
Smallest prime number, etc

>>5037577
>>>/v/

01011010

>>5041027

>only natural number that is perfectly aymmetrical both vertically and horizontally

What about 88,888,8888,...? Hurf.

For that matter, the same applies for 0 depending on the font, making 80, 800, 808, etc. also valid.

12 is the Master number obviously.

>>5037505

1 is the loneliest number

9 is the best number

i like 43.
