No doubt you've heard that the Large Hadron Collider (LHC) went on line this week in Switzerland. Scientists are hoping that the giant particle accelerator will allow them to smash protons into each other at such high energies that they will gain deeper insight into the composition and origin of the universe. You may not understand exactly what it's all about, but Kate McAlpine is here to help you with the physics of the LHC with this smash tutorial:
Actually you may not understand any more after watching the video than you did before, but you probably enjoyed the experience of not really learning anything. There's some background on McAlpine and the video here.
