New LHC Physics Phase Begins!

cern-first-physicsWell, here we go. It has been a little over 20 years since I’ve been actively working in this field and have been hearing about the promise of this machine, the Large Hadron Collider (LHC), and now it is really here, working, and colliding protons at an energy much higher than any previous experiment, promising us to a glimpse of new aspects of how the universe works. It is not guaranteed, of course, but there’s a great deal of hope, and so much of what we know strongly suggests that there’s going to be some exciting things to learn. See the list of related posts below for several bits of background on the LHC, or go to CERN’s website.

LHC Update

04collide_600Dennis Overbye wrote a nice summary article in the New York Times about the current status of the delays to the Large Hadron Colllider’s (LHC’s) re-opening. (Photo left by Valerio Mezzanotti for NYT) The issue is very frustrating, overall, even though one knows that delays like this can happen (and ought to be expected to happen) if you’ve built the largest and most complicated machine ever. I (and many colleagues) have in some sense waited for the LHC almost my entire professional career, and last Summer/Fall it seemed so close to finally starting to give us physics, only to have the failure happen, and set it all back. That’s life, of course. These things happen. I’ve a great deal of faith in the […] Click to continue reading this post →

lhc_and_mont_blancJester at Resonaances reports on a talk by Jörg Wenninger about the progress at the Large Hadron Collider (LHC).

There’s information about the repairs, more thoughts about the accident last year, and somewhat frightening news about issues of quality control on some of the manufacturing of crucial parts that may haunt the entire project for some time to come. […] Click to continue reading this post →

Yvette on LHC Poetry

By | | , , ,

yvette cendesAha! Regular commenter Yvette Cendes (over at The Chocolate Fish) has thrown down the gauntlet! She thinks that we can come up with more, and better, poetry about the LHC. The successful LHC song of Kate McAlpine (deserving of thunderous applause for raising awareness) should clearly be considered just the beginning. So she starts off the challenge to you all with some work of her own, which I shamelessly reproduce below. (Go over to her blog to submit your new writing – or do it both here and there. Up to you.) (My money’s on our regular commenter Elliot producing a marvellous LHC haiku or something like that.)

Yvette calls it an LHC Poetry Slam. Hmmm. I submit that it should be an LHC Poetry Event, or LHC Poetry Collision, or…. anyway, here’s her poem, and wow – true to form, it is good! […] Click to continue reading this post →

Tales From The Industry XXII – Live LHC Chats

Just the other day, while coordinating some work being done on my house, I was thinking that it is time I learned Spanish. Most of the people working in the construction industry here in Los Angeles have Spanish as their first language, and besides the usefulness it would give in communicating difficult ideas about a piece of work to be carried out, I really don’t like the feeling that I’m disconnected from them. I’d like to be able at least to, in Spanish, offer a cup of coffee, or a glass of iced water, and have a little small talk – treat them like fellow human beings as opposed to “the help” as is done so much in this city, to my disgust. I interact a lot with the Spanish-speaking parts of the city through my use of public transport, places I go to grab tasty food from time to time, and so on, but there is still a sense that there is an entire alternative Los Angeles out there that I am only barely touching upon by not knowing the language.

Then yesterday this whole Spanish language issue came up again in a big way. There was a phone call to the department from Univision, the Spanish-language TV network. Probably most of you are wondering what that is. You know those several channels that you never watch and when you flick by them, all clustered together, they’re always speaking Spanish and discussing issues or people that you seldom (if ever) have heard of? Yes. This is one of those channels. There’s a huge part of America (and elsewhere) that tune to those channels primarily.

Well, the people at Univision had heard about the excitement about the Large Hadron Collider (see, e.g. last post) and wanted to do a piece on it, and have someone in the studio to talk about it live on their breakfast show. They were looking for a […] Click to continue reading this post →

Inside the LHC!

Comments Off on Inside the LHC!

I recommend these videos that show the inside workings of the ATLAS detector of the Large Hadron Collider (LHC) using animation. They are quite stunning and simply lovely. Science aside for a moment (and you can learn about it in the posts listed below), remember that the LHC is simply the largest and most complicated device ever constructed, with the largest team of scientists assembled. It is a wonderful reminder of the international, collaborative, and cross-cultural nature of science. […] Click to continue reading this post →

Phil at LHC

Do you listen to the CERN LHC podcasts? They can be good. Every now and again, there’s a visitor there, and Brian Cox interviews them on site at the Large Hadron Collider. (Search archives for LHC or see links to lots of posts on it below, such as this one.) The most recent visit is by Phil Plait, aka the Bad Astronomer. They chat together about various aspects of the science to be done at the (soon to be switched on!) LHC, research in basic science in general, the scare-mongering business about the black holes destroying the earth (see here and here), conspiracy theories, and – of course – […] Click to continue reading this post →

More Trouble for LHC?

[Update:- NB: This was an April Fool joke. -cvj]

CMS detector - New York TimesSome breaking news for a change. I’ve only heard snippets of this and so I’ll update later with more as I get it. That silliness that was in the news about two physicists pursuing a lawsuit against the Large Hadron Collider has suddenly become serious. (Image right: the CMS detector at the LHC, taken by Valerio Mezzanotti – from a NYT article last year.)

Recall that the issue was that there would be the possibility of the experiment creating mini black holes that could gobble up the earth and that the CERN scientists have not done enough to demonstrate that this was not a safety issue. Of course, and has already been said in several places (see e.g., Phil’s general level post about the physics and the case here), this is utterly ill-conceived and in any case certainly not the way to go about things, but it seems that the legal route can be quite damaging for science, in the right hands.

What seems to have happened is this. Since the suit was filed in Hawaii, it falls under US Federal jurisdiction, and has been taken up as an emergency issue before the Supreme Court. Somehow the litigants got a hearing on this with the help of powerful friends who have what can only be thought of as another example of the anti-science agenda we’ve a lot of in various branches of the government in recent years.

The upshot is that the Supreme Court has announced today that they are requiring all […] Click to continue reading this post →

LHC Podcasts: Science Meets Science Fiction

By | | , , , ,

Confession: I’ve no idea what Torchwood is, and I find the current Dr. Who shows annoying overall (there have been some good episodes that I’ve seen, but they’re swamped in a sea of such poorly thought through and simply phoned-in crappy episodes that I find it too annoying to take the risk of wasting an hour I could have better spent with my head in the oven…) Feel free to disagree with me, and I have not seen the most recent season, so maybe things are better.

LHC You TubeBut anyway, where was I? Oh, right. Someone called John Barrowman (apparently one of the stars on those shows? He plays a scientist? I honestly don’t know, but you will, if you’re a fan) took a visit to CERN (the particle physics lab in Europe you often read about here and elsewhere) to better inform himself about the intersection between science and science fiction. One of the resulting jumpy noisy and (reportedly) fun videos can be found on YouTube here. There are some somewhat interesting animations alongside some of the, er…jolly madcap fun, illustrating the physics. Following the particles along the beam-pipe to the collision is not a view I’ve seen before, I’ll admit.
Much more interesting is something they mention at the end. A series of podcasts on the LHC (the big experiment at CERN we’re all interested in and excited about). This is driven by Brian Cox (no, not that one, this one, the physicist), and seems to be in a […] Click to continue reading this post →

CMS at LHC NYTimes

One of the Large Hadron Collider’s detectors, the Compact Muon Solenoid (CMS).

As you gather a lot when there are discussions on the topic here and elsewhere, there’s a lot of excitement and anticipation among high energy physicists about a number of things. I would go as far as to say that we are already in a very rich experimental time for results pertaining to high energy physics (or, if you insist, “fundamental physics” issues (I have in mind, for example, all the wonderful cosmological and astrophysical data that continues to come in, with more to come), and it is set to possibly get much richer – maybe even a new Golden Age with a little bit of luck – when the Large Hadron Collider starts producing results. We are really going into the (relative) unknown with this experiment, and this will be a great time to be working in the field – with a little luck, as I keep repeating.

A number of substantial articles have recently appeared in the general media that give you a good sense of what is going on, more reasons (and more detail) for why there is […] Click to continue reading this post →
