Today the LHC is switched on!

The Large Hadron Collider is to be switched on today. This is the largest and most powerful particle accelerator in existence and has been years in the making. While it has many applications, the most exciting by far is the potential to discover the Higgs boson, the particle which defines the masses of all other particles. There will obviously be a gap between when they switch on the electromagnets and when they run the experiments that we've all been waiting for, but it certainly is an exciting prospect.
What I find really interesting is the way the line between energy and matter has become blurred as we have delved deeper into the nature of each.
The first major step was in Einstein showing that energy and matter were equatable. Next the discovery of light quanta or photons (packets of light energy which have momentum and behave like particles) Then the discovery of wavelike behaviors of particles, which had traditionally been confined to the realm of energy.
The standard model of particles predicts a carrier particle for each of the fundamental forces. If this is the case then it is possible to have very small particles that lack a Higgs boson so have no mass, has a wavelength, but are still essentially what we would call matter. This sounds to me very much like a photon which is definitely energy.
