Re: Several biggest errors of particle physicists.
Splitting the topic around here would be reasonable.

Re: Several biggest errors of particle physicists.
I don't understand why they keep on working with vectors, they are no good when things become complicated. Possibly because particles have a velocity (A speed and a direction) at every point at which they're measured? Velocity being a vector quantity. Vectors see heavy usage in particle physics in ...

Re: Several biggest errors of particle physicists.
Something has triggered the software to come up with this. Indeed it could be nothing, but what if a particle starts to fly in an unexpected direction or way, for which the software isn't designed to calculate, than the result would be ... ? Either a best approximation of "normal" behaviour, and/or...

Re: Several biggest errors of particle physicists.
Perhaps not in the vacuum of the beam pipe but once the collisions happen there is a lot of Bremsstrahlung, and there are Bose quasi-particles (phonons, magnons, plasmons) I don't think the particle densities exist for phonons etc to exist and propagate within the collision debris Indeed the standa...

What really happens at the LHC
Brian Cox talks about what happens at the LHC
Not finished watching it yet, but it's a nice explanation of the experiment so far.
Couldn't see a link to it anywhere else on the forum, so thought people might want to take a look.

Re: Let's go hump hunting!
UK grid is 50Hz, +- 1% (By law, in practice it's closer)
50.50Hz is right on the upper bound of that range.

Re: Protons
I'd expect most of the D2/T2 to have been removed before the gas was bottled, as these have uses elsewhere. Eitherway, any stray D/T would probably be "left behind" as you said Danny. They won't follow the same curvature in a magnetic field either, so would impact against the sides of the beam tubes...

Sounds like you're still trying to get onto #lhc on efnet.

Re: Where is a good "IP For Dummies" description?
Courtesy of one of the guys in #lhc today, we have a nice animation showing the process of aligning the beams for collisions at an IP

Re: Disco Legend Zeke enters the room.
Thanks for the welcome. No problem :) In truth it is not Math free, but its a math of probability, slot machine pulls. In spite of its simplicity, it can explain stuff like single photon slit experiments without treating our poor photon as a wave. Sounds similar to existing quantum mechanics. Apolo...

Re: Disco Legend Zeke enters the room.
Understandable but math free -> Cannot be calculated -> Cannot be proved/disproved -> Has no value. If your model has mathematically well defined experimental properties, brilliant :) Time to start seeing if it's a potential contender, alongside string theory, supersymmetry , extensions to the stand...

Re: Proton vs Graphite
Perhaps this will help. Yes, the dump will have involved 3.5TeV of energy. A 3.5TeV collision is one where the energy involved is 3.5TeV and the total momentum is zero (or very close to zero). As the dump into the graphite has non-zero momentum, it isn't a 3.5TeV collision in the particle physics se...

Re: Accelerator magnet models
Looks nice from the picture on the website. Can't run it on here (No VectorPlot in Mathematica 6), but I look forward to having a proper look on Mathematica 7 when I'm next in the labs
