Why do I like physics? 
Because I'm a human being
and it's in my blood, it's in my DNA.
You might as well ask me why do I like to eat?
Why do I like to make love? 
It's the same thing
It's something that's essential for humanity, for our species.
We eat so we survive today, we make babies so we survive the next generation
and we make science because science will help future generations to survive.
Obviously it's music, right! I got the LHC
running now, ATLAS you're my home!
It's music because what we do here is either solos or duets
there's been all kinds in science and history
At CERN, we have big beautiful orchestras
and it's essential that these orchestras, which are our collaborations, all work together
and that everyone pulls their role for the
music to flow
So what I can't prove is this, but I have a pretty good idea it's true.
We live on one beautiful small blue dot
which is one planet in a solar system
which is one solar system in a hundred billion stars in our galaxy
and there are a hundred billion of these galaxies
I have a doubt in my mind that
we are ever really going to be able to completely understand our entire universe
on the other hand, what I do know is I love working at a place like CERN
where people have dedicated their lives to try to find that answer
