My username is just... my name, I'm used to register as Sidus (my youtube account) or SalvoSoftware, but here, i decided to write Salvo, as my friends call me, just for a change biggrin

What about you?

My username is an altered version of my first name, which is Antti. The 2 at the end is there just because "Antza" is usually taken.

Mine is my first name as well, but I guess you could've guessed that yourself :P

Nice name. smile

I thought about making something clever or space-related for my SE username, but then I threw my hands in the air and went with this. It's my default handle when I am internetting. tongue

VoeKoeVaKa means "-1/12" in a language I invented. I love this number because as Euler prooved, 1+2+3+4+5+6+7+...=-1/12.

For most people, this result is false, because adding numbers that get bigger and bigger can't lead to a finite negative result. But I don't see things like it. For me, the series does not converge to this number, but the sum is equal to this result, because it have its properties, and I think that the properties makes the object, instead of the object makes the properties.

This is the most simple proof I found for this result :

We call :

O=1+3+5+7+9+... the sum of odd numbers
E=2+4+6+8+10+... the sum of even numbers
so O-E=1-2+3-4+5-6+7-...

Let's assume f(x)=1-2x+3x2-4x3+5x4-...
=Σ( (-1)n(n+1)xn , n∈⟦0,∞⟦)

Let's g(x) be a primitive of f(x)
g(x)=x-x2+x3-x4+x5-...
=Σ( (-1)n+1xn , n∈⟦1,∞⟦)

Let's assume h(x)=1-g(x), we can found an analytic form of h(x) :
h(x)=1-x+x2-x3+x4-x5+...
=1-x.1+x.x-x.x2+x.x3-x.x4+...
=1-x.(1-x+x2-x3+x4-...
=1-x.h(x)
⇒ h(x).(1+x)=1
⇒ h(x)=1/(1+x)

⇒ g(x)=1-1/(1+x)

⇒ h(x)=(1+x)-2 by differenciating.

By assuming x=1, we get :
f(1)=O-E=1-2+3-4+5-6+7-...=(1+1)-2

Now take :
E=2+4+6+8+10+...
=2.(1+2+3+4+5+...
=2.(1+3+5+...+2+4+6+...
=2(O+E)

So let's solve the system :
O-E=¼
E=2(O+E)

⇒-E=2O
⇒3O=¼

⇒O=⅟12
⇒E=-⅙

O+E=1+2+3+4+5+6+7+...=⅟12-⅙=-⅟12

A similar proof can be done using the Riemann zeta function, but I will not detail it : ζ(s)=Σ( n-s , n∈⟦1,∞⟦), and we can have an analytic continuation of ζ(s) with the equation ζ(1-s)=2.(2π)-s.cos(πs/2)ζ(s)Γ(s) which gives ζ(-1)=-⅟12.

To conclude, I can say that this series summation operator is different than the common one, and infinity can be interpreted differently.

Well as you can see my own nickname comes from the very famous batman antagonist and especially the Dark Knight (potrayed by Heath Ledger) one of my favorite movies biggrin !!

I'm bad at making up usernames so I decided to make this; I roll with it. Nearly all of my accounts everywhere are either this username or variations of it.

Yeah, it doesn't really "equal" this, anymore than the series 1-2+3-4+... "equals" 1/4. It's a result of using an extended/generalized definition of 'sum', specifically the Abel Summation, which was developed to handle divergent series such as this. smile

Nah, it's more of a play on anonymity.

My username was made by one of those random name generators in some game I used to play, and now it's my name pretty much everywhere on the Internet.

In late 2005 I sat down at my friend's computer and opened Starcraft. I wanted to make a new profile, but of course I couldn't just pick any old name. So I sat there and stared at the screen for about half an hour thinking of names, and eventually I came up with "Harbinger Dawn". I thought it was the most amazing name ever and my friend thought it was really cool too. I've been using it for everything ever since.

My forum avatar is the S of Sidus, I used it here because i can use it for any name starting with S biggrin

Sidus came to my mind when I registered on YouTube, of course Salvo was already used, and SalvoSoftware too, so I came up with Sidus, that simply mean "Star" in Latin, and when Sidus is already used, I add Brist so it become SidusBrist that sounds good and means "bright star" smile
