Advent Calendar 2012 December 21st

How could the LHC cause the end of the world?! Well… it can’t. It poses no threat at all to the fabric of the cosmos.

   Obviously in this universe the world didn’t end but in the multiverse everything did Multi CERNs cause catastrophes in many worlds?

     I suppose so! Let us observe a minute’s silence for the destruction of some of the multiverses. (I’ll observe my minute’s silence in another universe, thank you very much!)

   On Stochastic cooling: Why the name? “Stochastic” to me means something random or unpredictable, but the idea of the actual method as you describe it has nothing indeterminate or random in it. Or does it refer to the cooling of the stochastic deviation from zero radial velocity of the particle?

     Yes, the name is a little odd! The term stochastic in this context refers to the fluctuations in the beam that the method tries to correct, so it should probably be renamed “cooling of stochastic processes”. The name may be due to physics at CERN being an international effort. We have what we call “CERNglish” which is roughly American English, with some other words added and some strange turns of phrase. I wouldn’t be surprised if the same thing happened with the name “stochastic cooling”.

     Sorry if I’m picking nits, but thinking a bit more I realized that the name is more than a little tautological – anything I can think of that can be cooled must be of a thermodynamically indeterminate nature…

     Anyway – Do you have any more examples of “CERNglish”? I am sure there is a lot of terminology that has stuck although being less than perfect.
