Well today I'm going to talk about the Large Hadrons Collider that is a particle accelerator built by CERN (European Organization for Nuclear Research), because I think that is an interesting thing.
It is situated at 175m under France and Switzerland and it’s 27km long. To understand what is a particle accelerator you have to know that matter is made by atoms and these are composed by electrons and have a nucleus with protons and neutrons. Now I can start telling you how it works: The investigators take the ions (that are atoms which have lost the electrons and have positive charge) of heavy metals as lead and they put it in a little accelerator, when the particle gets the velocity needed they put it in LHC. Then they take another particle and do the same. When the two particles are in LHC they crash and scientist propose is to see the elements which are made the protons that are the quarks which anybody have seen it yet. How they accelerate the particles? Inside LHC there are superconducting magnets. In addition when two particles crash there is a lot of energy so the LHC is covered by liquid helium that is at -272,2°C.
The scientist want to know which is the origin of the matter, the "God's particle".
Actually, LHC isn't working because on December 2008 they had an outflow of the liquid helium and they are repairing this.
I talk to you about this because I think that it's interesting to know that there is people that is working to discover the element which all of us are made of.

that is an interesting topic, we are learning that in science for our wolrd now at the moment, and its really interestin, but hard to understand.
i will look into this project more on the internet to understand a little better
see you on monday uri!!
I think that it´s incredible how we have progressed these years...
Who would think that we could discover how to build and use this mysterious technology!
C ya monday!
We did that in the last term in ciencies del mon contemporani... I think that I had bad note..

wow Oriol I can't understand you writing about the LHC! We've been through this in Contemporarily Science with Anna Sastre many times and I really hate it!haha
see you:)
it is a really intereasting topic to ponder at weel the thigs collided gives you sometimes an antimatter which is the mirror or the opposite of matter. When antimatter comes with matter it annihilates and gives out the purest form of energy
