atom smasher (Large Hadron Collider)

You may already know this, but colliding hadrons is particle (or high-energy) physics, while smashing atoms is nuclear physics. The man on the street likely doesn't know the difference, but physicists know the two kinds of phenomena are orders of magnitude apart in energy. Nuclear physics means a few MeV; particle physics typically starts in the GeV range (where you have enough energy to generate protons) and goes up from there. Roughly speaking you might say particle physics is as far from nuclear physics as nuclear physics is from atomic physics. They're all completely different animals.

  CERN is going to fire-up it's atom smasher (Large Hadron Collider) this week and maybe do a brand new test next week. It could destroy the world as we know it. Some are afraid that it may create some micro black holes which will destroy us. They are filing in court to stop this from happening.

  Meanwhile, Kate McAlpine, 23, a Michigan State University graduate at CERN, has produced the Large Hadron Rap, a video clip that has attracted more than a million views on YouTube. It is awesome- a must see. I really enjoyed it. Here is the URL:
