I have a 12 24in monitor setup at work when I'm on shift. The guy next to me has 6 24in + 4 40 inch monitors. Its very nice:) Although the heat they kick out is insane. We do actually need it as well so this card is of interest to us
To prove it, heres a web cam, my station is the big one at the end. That said I imagine we are a fairly unique case, I dont think many people need to monitor and control the triggering and data acquisition of a large particle physics experiment. But just pointing out there is a use case for the card:P
When I first saw that link, my first response was "My Car!!!", as I was sitting in the control room on shift at the time. Second thought was "this is going to be an awkward e-log entry":)
See its this exact type smart arse reply that degenerates slashdot so. Explain what is incorrect rather than making anonymous side remarks. I'm only talking about colliders which annhilate their particles, eg LHC, Tevatron, LEP, CLIC, ILC which are type of particle colliders associated with particle physics. Sure you you have cyclotrons but I dont really consider them particle physics and not really in the scope of colliders like this article was talking about.
My appologies, it came out wrong. I meant before somebody says to me "but the LHC is proton-proton, you suck". It was a slight tongue in cheek reference to the usual level of slashdot responses by people who know nothing about which they are talking about:)
And just to add to this. All particle colliders are mater-antimatter colliders, it just doesnt work otherwise (charge conservation) Thats right, every single particle collider where you are annihilating the particle is matter-antimatter.
Now before somebody says, but the LHC is proton-proton, you suck, the LHC is actually a quark-anti quark or gluon-gluon collider. Protons are not just 3 quarks, due to the strong interaction there is also a sea of gluons and quark-anti quark pairs which carry the momentum of the proton. At the energies of the LHC, this sea becomes important.
The article is terrible and horribly confused. Reads like something from the Sun (a gutter British newspaper for non Brits).
come on people, at least read the summary, I know this is slashdot but still:) They used a golf ball and sent it 600 yards. I bet it's pretty easy for the kid to get some more.
Nah its possible. I started WoW in the last week of June and I'm level 57 currently. And its very possible to level without running instances so you wont know how to fight bosses.
That said, I've had a much better experience than the OP and its very easy to read guides on ten ton hammer, wowwiki etc that fill in the knowledge you need.
Well when you find the Higgs, you want to measure its properties and see if you really have a Higgs and not some random new particle. And then if it is the Higgs, you want to see which Higgs it is. All this takes time and lots and lots of data.
And unless we are very unlucky, there should hopefully be lots of other werid and wonderful things to find. I'm personally not interested in the Higgs at all but much more exotic things. But for the media, its easier to say "we are looking for X" rather than we are looking for "X, Y, Z oh and dont forget about B but to be honest, we dont know what happens at these energies and would like to find out"
I'm with you, the game is good but god damn its buggy as hell. I've lucked out in that its playable for me but its still a little ropey. Graphical artifacts occasionally on the far right (a dial appears there flickering), occasional crashes to desktop (relatively rare although molerats seem to cause it frequently) and alt-tabing means instant hang. I've noticed that if it starts crashing, it will become much more frequent untill a reboot.
Again this is on a fairly standard high end build (at the time) that has no problems with any other games (8800 GTX + Q6600 + vista).
So Bethesda, its a great game but I'm not buying any DLC untill the main game is a lot more bug free.
Exactly, you're spot on, a lot of this style work is done by students of some description under supervision from a more experienced physicist. The student is told by her supervisor, go find out which jet algoritm is the best using these and these criteria. She looks at it, finds a minor issue and solves it.
These undergradutes are members of the collaboration working under supervision of experienced physicists so they have full access to everything. Anyway consulting the technical design reports will give you some hardware info on CMS but its not really presented in a way accessable to a non physicist.
its not really a design flaw. Basically its a minor bug in the algorithms (if I'm reading it right, the article is very confused to say the least) which allow physicists to reconstruct the energies of hadronised partons. Now we can do it a bit better and make slightly better measurements. This software we know isnt optimal, it requires a great deal of knowledge to write and to be honest a major part of the effort in the earily days of an experiment is improving the reconstruction software with fixes such as this. And there will be many more such improvements. Bugs here do not pose any danger because the software is run *after* the event has occured so it cant effect the event, just our understand of what actually happened.
Also just to make clear that the LHC and CMS are very different things. The LHC is the accelerator and its what makes the particles go very fast. CMS is a detector, it just sits there and records what happens in the collision. CMS is built and designed by a completely different set of people to the LHC. CMS doesnt need the LHC to function and the LHC doesnt need CMS to function but they are a bit pointless without the other.
yeah its just an algorithm bug (having just checked this out), its no biggy at all. Its good that its fixed but CMS (and other particle detectors) are very impressive peices of kit which are very difficult to understand. It takes hundreds of scientists years to fully understand such a detector, continously making small improvements such as this. Its good and it clearly shows she has the smarts to do a PhD but its not exactly the earthshattering stuff the article makes out.
Its not actually amazingly impressive, its made to sound a lot more impressive than it actually is. One the meeting in question was "CMS week", one of several weeks a year we get all our collaborators together at CERN not CERNs annual meeting. She's basically improved our jet algorithm (as far as I can tell, the article is woefully lacking in details), a decent job for an undergraduate and will certainly help her walk into a PhD place as a shes clearly good enough but she's certainly not the only undergradute to have made a contribution such as this.
I'm with you. I take out 100 euros and 200 CHF a week and its much easier to stick to a budget than doing it by cards. I probably spend less this way, if somebody says lets head out for meal, I can just look at my wallet and see if I can afford it. Although maybe I do spend more because on friday nights it can be, hey I've got 150 CHFs left, lets hit Pickwicks in Geneve and taxi back home to France:)
The Higgs would just be the icing on the cake of an already highly successful Tevatron physics program which is coming to its end. The Tevatron was built to find and measure the properties of the top quark which it did. It also produced valuable Bs mixing measurements sheding light on mater-antimatter asymetry. It has produced many fantastic results (sadly) confirming the correctness of the Standard Model (at this energy scale) and has set stringent limits on many beyond the Standard Model theorys like extra dimensions and SUSY.
they are and they arent. Fermilab is a big contributor to the LHC (although some of the contributions did go bang, hmmmm) and will play a big role in its future. Lots of scientists are on both an LHC experiment and a Tevatron experiment (although they tend to be senior, PHD students and postdocs who do most of the work tend to be on only one). It would be actually hard for the labs to work together more than they actually are. But there is also definately a little bit of a (friendlyish) race on to be the first ones to see it. In the sense, we'll help you as much as we can but we also want to beat you, its a little odd to explain.
Anyway theres pretty reasonable indirect evidence for the Higgs, lets just say to make all our measurements consistant, it would be nice if a fundamental scalar existed around 115 GeV. And it would be even nicer if it generated all the masses in the Standard Module while it was at it. There is certainly enough to have a reasonable Bayesian prior.
Imperial College used to have this policy cira 1999. However there then was a major push by the then new rector for entrepreneurial spirit and using our degrees to come up with new practical commercial ideas. To his credit, he saw the policy that Imperial would own all the ideas as counter productive to his aims and gave us ownership of anything we came up with.
Just a small point: positrons!=anti protons, so this isnt beating fermilab just yet:)
Positrons are pretty easy to make as they are a fundamental object and are readily produced by photons. In fact as a high energy photon hits matter, it will pair convert into an electron-positron pair. So to make a positron you just need a big laser:)
Anti-protons are very difficult because you need to produce 2 anti up quarks and one anti down in a pound state. Thats as tricky as it sounds. In practice you just bash a stream of protons into a target and hope for the best. Hence the rather low efficiency.
You produce anti-matter in anti-matter-matter pairs. Ergo your idea can not work.
I spent a while thinking if you could exploit the W boson which produces anti-matter - matter pairs of different flavour but I couldnt think of a way. Regardless any way which somebody could come up with would give such a small theoretical energy gain that you would almost certainly lose it through efficiency loses.
If that somebody has accepted and benfitted from societies gifts to him, I think the society has every right to ask him to contribute towards bestowing simliar gifts on the generation.
As an example, if we stopped funding fundemental physics research into at the time very abstract things such quantum mechanics as a society 100 years ago because people didnt want to pay, we wouldnt have transistors or lasers. Without those, the modern world would be a bit different. I think if we take advantage of things our forbearers paid for us to have, then we should again contribute similarly at a level appropriate to our means so that future generations can have things we cant even dream of now.
CERN always shuts down in winter. Power demand is at its peak in winter in France so its too expensive to run the accelerator complex. The winter shutdown has nothing to with the LHC.
I completely see your point. I really do. And I really think arXiv fills a valuable role in making non peer reviewed research available for this very reason. Its just that for every Darwin, Einstein or other scientist that fundamentally changes the foundations of science, there are thousands, if not more, of crazies. Seriously go to the poster session of particle physics the APS meeting and you'll see what I mean.
