So yesterday was the announcement of a massive breakthrough: CERN have discovered a new particle thought to be a Higgs boson. This is a milestone discovery future generations will have in their textbooks. Maybe it is a good time to remind the excellent animation Jorge Cham published a few months ago, explaining in simple words what the Higgs boson is. (it is also a good time to have a look at the photos taken soon before the launch of the Large Hadron Collider)
