Funny, I signed up for a survey yesterday which pays you an amount of money depending on how much time it takes you to finish it. They send them to your e-mail, and you can decide how often you want to participate (they can send you up to 6 surveys a month). They also have an option where you can decide to send the money you earn to a charity if you'd like, all made very easy, you even get your own cpanel to check your status. This one was Swedish only.

I came across a site last year that collected links to various free stuff you could get. Unfortunately, I forgot it's name, maybe I should try find it again. I came across the link collection from a site for students, there were loads of these free offers everywhere. Before I found the site, I had a hard time to believe that people would willingly give away stuff like this for free.
I think one company were launching a new product, and before the actual release, they wanted people to try it out, by literally giving a limited amount of them away. You'd have to be fast before they run out! Another gave away free candy, but I was too late for that one, doh =p

If you have some spare time every now and then, it's worth taking a look, and perhaps try it out.

Antimatter can't be used as an energy source this way, it's not efficient enough. It costs more energy to produce than we get out from the actual annihilation. It's pointless. Since there's not so much antimatter around, you'd have to create it.

Do you follow all the steps I did?

Devanté: What browser are you using? I got no ads at all, and not a single pop-up. I use Firefox with NoScript, it makes your browsing experience a real pleasure. Try it

Generally speaking,

The left side is your derivative. Does this help or should I give you some hints?
When you've got the derivative, set it equal to 0 to obtain your equation, then solve for t.

Zhylliolom, or maybe someone else could explain what happened here, I'm a bit puzzled :

I noticed the geometric sum after that, but I've never worked with double sums before, ever. But does it basically mean that you take the sum over the sum, as in (k=1 to ∞) first and then (n=1 to ∞) over that previous sum?

If so, I learned something new by reading your post

Well I didn't even have time to install it fully before it crashed. I picked language and *poof*  and my computer rebooted. Didn't get the chance to enjoy it's positive aspects one bit : )
I saw there was an add-on for VST's, that's neat because I use them a lot.

Start on either side and load up as many grenades as you can, it will bounce to the other side right after it hit either of the top monsters (?).

I know who made this game, it's a friend of an ex-classmate, never thought I'd find it here

If I had such a revolutionary algoritm in my hands, and only in my hands, I sure wouldn't keep it for myself, it doesn't matter if I'd give up the million dollars. Go talk to a mathematical doctor about it, maybe you're up to something, but most likely you're not.

If you had been reading up on university math, as you claim, the proof Ricky asked you about would've been easy the traditional way. It was one of the first proofs they introduced when I started my first year at university. Actually, a whole lot has been about proving this and that, you'd surely know that math at university level is a whole different game (it's more fun too! )

Trance, ambient, chillout, new age, metal, pop; in fact pretty much everything except country
Bands/artists I like in particular are Armin, Solarstone, Matt Darey, Pain, Enya, Origen and Röyksopp.
Favourite song would be Solarstone feat. Jes - Like a Waterfall (Solarstone Deeper Sunrise Mix)

I'm into Sudoku as well. Actually, that's the only one I can think of being math related. It's getting pretty big around here, it's in the newspaper and there are particular magazines full with puzzles only.

I have some huge integrated sudoku puzzles which I still need to solve, they take like more than a day to solve each
I've never heard of Addoku though, I will most definitely check it out.
