The next thing we want to do with those particles is to give them some energy. That's the basics of how an accelerator works. I've got a machine here called a which does that...

So the final thing that you probably shouldn't do with a particle accelerator is: You probably shouldn't destroy the Earth with it. ...People seem to think that when we design new massive particle accelerators that are going to have particles that are huge energies that we've never created before in the lab, that somehow... we just built it for the lulls, and then we're going to destroy the earth with it, and that we haven't quite thought it through, and that we're not quite sure what we're doing... If you're at all concerned, please go to HasTheLargeHadronColliderDestroyedTheWorldYet.com and... you can tell me what you find there.

[T]his is called the Standard Model Lagrangian, that curly <math>\mathcal{L}</math> at the start is for Lagrangian... and there's lots of different components of that. Now if I write it out in full, I get what is the most egotistical physics teacher in the entire world. So if I wrote it out in full... really you don't need to read it, I promise, all of the different terms in that equation describe an interaction between different types of particles and force carriers...
