I think you're conflating issues. When you're in a field, it's your job to question everything the other experts in the field claim, especially when the claims are dramatic or unexpected. When you're not in a field and want to know something about it, then it's perfectly OK to use experts analysis as a baseline for further study.

It's not OK to dismiss all the experts in that field as crackpots just because you don't understand what they're saying. For instance, if Feynman showed up and told me that there are charm quarks, then I'd be unjustified in dismissing him.

This is interesting, because this is exactly the sort of thing that Tim Berners Lee sought to avoid when he envisioned the semantic web.

These papers and abstracts should be properly hyperlinked to other papers (or even a google search) to properly define what many of these terms mean. A lot of the jargon seems specific to either accelerator science, or even just the LHC.

I am a physicist who has worked on accelerator applications, and could only barely understand that abstract. It's very poorly written, and makes a far too extensive use of very specific jargon/acronyms to be comprehensible to even a physicist that happens to not be affiliated with the LHC.

Even an undergraduate should know better than to write an abstract like that. The general incomprehensibility, the use of extremely specific and unnecessary information ("Â±147 m and Â±220 m from IP5") would be perfectly sufficient justification for a failing grade.

I'm truly ashamed of my colleagues for writing this.

Okay, why not...
• pp: proton - proton
• cross-section: particle interaction rates are measured using "cross section". Imagine a billiard ball colliding with another a billiard ball. The cross section is just it's area seen from one side: pi r^2. But quantum particles are not hard solid spheres and can pass through each other, resulting in cross sections much smaller. The unit here is the "barn" = 10^-28 m^2. The total p p cross section is about a milli-barn. Higgs is about a pico-barn. Z bosons are about a nano-barn.
• luminosity: inverse of a cross section. This is how we measure the amount of data. It is the "intensity" of the beam. (luminosity)*(cross section) = number of (expected) collisions. The LHC is expected to collect about 1 inverse femtobarn in the first year of operation, and 300 total.
• elastic scattering: p p -> p p. Used to measure luminosity. (TOTEM's primary function)
• diffractive scattering: p p -> p p + X. This has been proposed as a high precision but low rate way to detect the X=Higgs. In this scenario, TOTEM sees the final p p and X ends up inside the CMS detector. (TOTEM's other primary function)
• pseudorapidity: a measure of angle: \eta = -ln \tan \theta/2. At \eta=\infinity, \theta=0 and at \eta=0, \theta=90 degrees. Pseudorapidity has nicer properties under Lorentz Transformations [wikipedia.org] than angle.
• Roman Pot: a particle detector device which is lowered into the beam line to detect particles traveling very close to the beam. It detects protons scattered by very small angles.

There's a reason a Ph.D. takes 4-6 years. Gotta learn all this.

P.S. TOTEM is one of the minor experiments. Now go read about CMS and ATLAS. :)

For those of you who still don't know what gaffer tape is, you may substitute "duct tape" to sufficiently understand the parent poster's humor.

However, gaffer tape is far superior to duct tape in many aspects. It's made from cloth, rather than plastic, and doesn't tend to destroy whatever surface it happens to be applied to.

Til in the hearts of the detectors, theyre made to collide
And all that energy packed in such a tiny bit of room
Becomes mass, particles created from the vacuum
And then

LHCb sees where the antimatters gone
ALICE looks at collisions of lead ions
CMS and ATLAS are two of a kind
Theyre looking for whatever new particles they can find.
The LHC accelerates the protons and the lead
And the things that it discovers will rock you in the head.

Come on, let's drop some particle physics in the club!

I had thought that NIM (Nuclear Instrumentation & Methods, owned by Elsevier) was the only game in town, but it's good to see that there's another journal for this sort of stuff.

(five minutes of browsing later) The Symmetry mag article has a link to the SLAC "blue book", which looks substantially more approachable.

Plus, given how slow my download is going, JINST is being slashdotted. ;)

If anyone ever needs a reason to wallop copyright, let this quote from the article [symmetrymagazine.org] be that reason;

Most copies of The Blue Book had vanished from the SLAC Library, and the librarians wanted to make it available electronically. But they ran into a snag: No one could figure out who owned the copyright, so there was no one to give permission to put it on the Web.
"It's an orphan work," SLAC archivist Jean Deken told me Friday. The original publisher was bought by another, which was bought by another, and so on. Finally, with the help of an expert from Stanford Law School, librarian Abraham Wheeler tracked down the current owner of the copyright-which said that since it could not find any documentation on the book, it could not grant permission to reproduce it.

What about the poor deserving lawyers? Where is the DRM? The commercial propaganda about "IP"? The hundred page license? The attempts by assorted hangers on to profit at other people's expense?

I think the lawyers should form a class action lawsuit for loss of income. It's just not right that somebody should be able to do something without numerous lawyers attached.

Where's the stuff about how they'll turn the world into a black hole? Hopefully that won't happen. It would suck. Like a vacuum cleaner. But with gravity instead of vacuum. :-(

Help to save the world from being destroyed by a black hole! The specs to the LHC (Large Hole Creator) are available. Create a detailed proof showing that the LHC will create a planet-destroying black hole when it is switched on. Send the proof, with your $75 entry fee, directly to me. The person submitting the first valid proof will be awarded a prize of$50 Million, to be awarded on Sept 12th.

Isn't it funny that the entire LHC spec is 1.600 pages, while the OOXML documentation, as submitted by Microsoft, is a full 6.000 pages.
Does this reflect a difference in complexity, or is it a sign of something else?

I was going to mod this up but can't decide if its funny, informative or what...

Regardless it doesn't reflect well on the OOXML spec - wonder how many of those pages could be culled by a good editing session and removing all the redundant repeated information?

• #### Re: (Score:2)

Try reading the ISO SQL spec. It might be shorter than OOXML (to be honest, I don't remember), but I am quite sure that it's longer than the 1600 pages mentioned here, when the relevant appendices are included.

MS is known for bloat and the LHC ain't as complex as people think.

The specification for Office Open XML has 6000 pages. And is missing some important stuff.
