Higgs boson I Presume?

Today scientists at Cern,the European Laboratory home to the Large Hadron Collider,have announced that they have found the Higgs boson particle.  

Its a momentous day for physics-I think. I'm still not sure what this means.

What is the Higgs boson particle?Where does it come from? Can we use it to build a Tardis?
Thankfully, this guy is able to explain it all.
