Just google it! You know the name, so it's pretty simple from here.
Why do they take a paper and write notations are movest they have I played.

You don't calculate with "algebraic" notation, you just represent the grid of the board with letters and numbers (like algebra) and then note which piece goes to which square. Here is the Ruy Lopez...
English Descriptive:
1. P-K4 P-K4
2. Kt-KB3 Kt-QB3
3. B-Kt5 P-QR3
Algebraic
1. e4 e5
2. Nf3 Nc6
3. Bb5 a6
What man?
Its a secret... You will need a really good chess coach to learn how to write and read chess algebraic notation 
And what were those posts about?
Well, he's asking a legitimate question about algebraic notation. Until my first tournament game I wasn't completely sure how it's done either.
Here is how they did annotation before descriptive notation:

I'll sometimes pull out a pen and paper and take down the moves while playing casual games OTB with friends just because it bothers them and gets in their head. Only works with certain people but it's fun to watch them get uncomfortable and lose focus. It's like you see in films where the person is super concerned with what their shrink writes down. I don't know why anyone would care, but, maybe it makes them feel like I'm a better player than I actually am.
Why do GMs in world tournaments have to record their moves by writing it down? The games will be observed and recorded all over the world.
It's required. Fide Laws:
8.1 In the course of play each player is required to record his own moves and those of his opponent in the correct manner, move after move, as clearly and legibily as possible, in the algebraic notation (See Appendix C), on the scoresheet prescribed for the competition.

Same reason pro golfers have to keep their own scorecard.

This answer fails to really address the question. The question was implying why is it still necessary in 2014, when their games are recorded and monitered.
Kaynight's answer of tradition is correct.
The reason it's required is for the TD to resolve disputes. I'd think it would be much faster and accurate to look at original scoresheets than to rely on a third party's notes, which may contain a mistake.

A lot of sports use instant replay. Why not use a computer-saved video of each game to resolve disputes or save the score?
"it would be much faster and accurate to look at original score-sheets..." 
Please tell me. Once I have gone for a tournament and I saw that some people brought some papers and started to write algebriac notations please tell me how do they calculate with these algebraic notation please....
