To be honest I won’t know what a large hadron looked like, let alone be filled with the desire to collide them into one another, yet today our understanding of the universe will advance a tiny step forward by doing just that. BBC reports the switch on and has a whole day of programmes devoted to the LHC. In depth information on it can be found here and here. Silly information on the LHC can be found here.
I can report that at the present time of writing, reality (whatever that is), has not changed. I only hope the boffins have plugged the device into a really hot cup of tea.
