New World of Physics is Emerging

How many of you know what LHC (Large Hadron Collider) is? I also don't know what the hack it is, in fact I never realize there is such term exists in this high tech era until I found out this special google logo today.


Initially I am not sure what was that mean, but it caught my eyes. I know there must be something big going on otherwise Google won't use it to embed into its logo. So, I tried to
put my mouse over the logo and I got this tooltip: "Large Hadron Collider (LHC)".



That term caught my attention as I never see such phrase before. What is it all about? I think this is a good question to ask Google. So I googled it and I got this piece of information from http://public.web.cern.ch/public/en/LHC/LHC-en.html which I will attach at the bottom of my writing.

I chose a more untechnical article to be attached here as I am not really good in science of physics. I feared of Physics subject in my school year as I couldn't cope with it. But after I left the school, I just realized that our daily life activities can't be seperated from the theory of physics. Every movement of us, any action we took the physics thoery will apply. Furthermore with the influence of my buddy, Chun who is really interested and good in this knowledge, so my interest towards this field is increasing.

I think this LHC will be a very interesting topic to be paid attention to for those physics lovers. I hope my physics-lover buddy will read about it then explain to me what is it all about, well maybe not in detail but at least roughly so that I can know the concept of LHC. Don't scold me for my laziness, I am not. Just now I read through some of the writing about LHC, but I can't understand because for me, they are too technical and out of my understanding.

Here are the piece of more untechnical information that I meant just now. From there at least I knew LHC is a huge practical experiment going on right now which may change human's understanding towards the theory of particle physics. It is a very important happening for mankind that's why it worths to be paid attention to.

Our understanding of the Universe is about to change...

The Large Hadron Collider (LHC) is a gigantic scientific instrument near Geneva, where it spans the border between Switzerland and France about 100 m underground. It is a particle accelerator used by physicists to study the smallest known particles – the fundamental building blocks of all things. It will revolutionise our understanding, from the minuscule world deep within atoms to the vastness of the Universe.

Two beams of subatomic particles called 'hadrons' – either protons or lead ions – will travel in opposite directions inside the circular accelerator, gaining energy with every lap. Physicists will use the LHC to recreate the conditions just after the Big Bang, by colliding the two beams head-on at very high energy. Teams of physicists from around the world will analyse the particles created in the collisions using special detectors in a number of experiments dedicated to the LHC.

There are many theories as to what will result from these collisions, but what's for sure is that a brave new world of physics will emerge from the new accelerator, as knowledge in particle physics goes on to describe the workings of the Universe. For decades, the Standard Model of particle physics has served physicists well as a means of understanding the fundamental laws of Nature, but it does not tell the whole story. Only experimental data using the higher energies reached by the LHC can push knowledge forward, challenging those who seek confirmation of established knowledge, and those who dare to dream beyond the paradigm.
