The reason the Large Hadron Collider was built was... to... investigate the fundamental constituents of matter... - Suzie Sheehy

That's only one particle accelerator. There are actually over 26,000 of them in the world.

There are foods which are naturally radioactive, but most of us would like to think we've never eaten food that actually been in a particle accelerator. ...That sounds a bit crazy. ...In the UK we don't eat many things that have in a particle accelerator but things like herbs and spices, and some other things occasionally go through a process called cold pasteurization, electronic pasteurization, which uses electrons from a to treat the food. ...It is legal in the UK and in the EU, and it's fully authorized... [T]here's a number of foods... which have been irradiated, or could have been irradiated, and that goes... from bananas, sometimes... to slow down the ripening process... so they have a longer shelf life... [A]s you increase the amount of radiation that these things are treated with... from some grains, seafood to kill bacteria, herbs and spices are a more common one, and then even sometimes higher doses on things like poultry, to kill .

[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...
