Comments Off on Once More, With Feeling?

Well, the good news is that there’s a definite schedule in mind for the restart of the Large Hadron Collider (LHC). (See related posts below for more.) We can resume licking our chops in anticipation of exciting new physics of various sorts! I learned about this from US LHC Blogs with posts by Steve and Peter. Some key things (apparently from a widely circulated email that heralds an official press release to follow soon) are as follows. First, Steve’s synopsis of the schedule: […] Click to continue reading this post →

Preparation

Yes, I’ve been a bit quiet of late, I know. I’ve so many things on, both professional and personal that it sometimes keeps me occupied from when I wake up just before sunrise right through to falling asleep a bit after midnight. And yes I know that means I’ve been not getting the traditional full nights of sleep, but if my body insists on getting up at 5:30am, who am I to resist? I thought it was due to jetlag from the trip a couple of weeks ago, but it seems to have taken. I don’t mind too much since watching the light change as the sun rises is a marvellous way to start the day.

clifford johnson preparing slides at the boardAmong the things I’m up to (yesterday and today so far) is a strip-down-and-redesign of a short talk for an exciting symposium that is coming up in a few weeks in Chicago. The American Association for the Advancement of Science is having their big annual shindig there (apparently the biggest science conference in the world) and there will be a number of addresses, plenary talks, and keynote speakers and the like (including Al Gore, by the way), and also several sessions of symposia and other presentations on various topics.

While slightly annoyed at the fact that one major day of the conference is on Valentine’s day (which means I’ll have to be out of town on just the day that maybe, just maybe, on the off-chance, you know – if the universe sneezes or something, somebody might want me to be their Valentine…*), I was looking at that day’s schedule and it caught my eye that there’ll be a session (with several presenters) entitled “The Science of Kissing”, and three hours long, no less:

I thought I’d follow Janet and do a sort of end of year review or summary (or, really, snapshot) in the following style: List the first sentence of every first post of the month for all twelve months. I’ve no idea what this will produce, so here goes:

I’ll admit that I was quite surprised by this.

Particle Physics on TV Tonight

marcela carena in atom smashers independent lens

I learned from Katherine on the US/LHC blog earlier that tonight on PBS is an airing of a documentary called “The Atom Smashers”. It’s about particle physicists at Fermilab, in Illinois (including my friend Marcela Carena in the photo above). I’m curious to see what they’ve put together, hoping that it’ll give the public some insights into the life of the various kinds of scientist involved, and the exciting physics that engages them – and those of us on the outside who eagerly await the results of their work. The search for the Higgs boson is a focus. You can see a trailer here. I’ll be watching, I think. It is at 10:30pm on PBS, in the Independent Lens series, but be sure to check your local listings since times may vary.

Enjoy!

Physics Can Change the World!

colbert lhc obamaLast night, Stephen Colbert suggested that the Large Hadron Collider is responsible for Obama’s victory on Tuesday! When it switched on back in September, it kicked us into an alternative universe in which everything was the same except that McCain’s position in the polls had been eroded, and, well, you know the rest.

(Apparently it also explains the World Series result, but as I know nothing about baseball, I cannot tell if that is really supposed to be an anomaly or not.) Clip here, and item in question is about 2 minutes in.

Hey team, run and cover… he’s on to us!

The 2008 Physics Nobel Prize

By | |
4 Comments

The announcement has been made. It’s for spontaneously broken symmetry in particle physics and it is to Nambu (1/2 – “for the discovery of the mechanism of spontaneous broken symmetry in subatomic physics”) and Kobayashi (1/4) and Maskawa (1/4) (- “for the discovery of the origin of the broken symmetry which predicts the existence of at least three families of quarks in nature”). It’s all about what might be better termed “hidden symmetries” in Nature, showing that the world (the structure of fundamental particle physics, specifically) is in fact much simpler if looked at in the right way. It is a powerful technique that does not just propose what the hidden patterns (symmetries) are, but tells you what the consequences of those patterns are in the form of predictions such that physicists can go out and measure those predictions and verify the existence of those symmetries. In some sense, this type of approach is the driving force behind a lot of fundamental particle physics these days – finding the hidden, simpler structure that lurks under the surface.

Here’s the announcement:

It Works!!!

Well, it seems that the largest and most complicated experiment in the history of humankind is…. working so far. They circulated the first beams at the Large Hadron Collider (LHC) earlier today! Even Google is excited. Check out their front page:

google\'s LHC graphic!

Fun live blogging reports from the scene of events over at Resonaances, US/LHC Blogs (several posts), and Superweak, for example. I got the ATLAS readout/image below from the latter. (Presumably this is the shower of particles produced when they did the “dumping” described in Resonaances? Or just stuff produced by the edges of the beam as it passes through?) Press release from CERN here.

Update: NPR’s Morning Edition had a nice report this morning in the form of a chat between Rene Montagne and reporter David Kestenbaum. Fun to hear the audio clip of the control room. Link here.

Thoughts During Break Time

Ah. I see that it’s been three days since my last confession. Gosh.

Well, it’s been a quiet weekend here in, er, my part of the universe. Good time for reflection and rest. I had a couple of posts I was going to do but in the end decided to break the pattern and change up my Saturday and Sunday, and the “change up” did not include the blog. So sorry about that.

I’m taking a break between an interesting meeting (that I will tell you about) and my office hour. The sun’s shining outside and it is not oppressively hot, surprisingly, so I’ll keep this short and poke my head out there again before my Physics 151 visitors arrive.

Some of the things on my mind: […] Click to continue reading this post →

Beaming With Anticipation

CERN Control CentreI just learned from the US/LHC blogs that the first circulating beam of the Large Hadron Collider will be attempted on September 10th. The press release is here, and is from where I stole the image (left) of the fancy-looking CERN Control Centre. This is so exciting! It’s not long now for possible new physics (some months or so beyond that date, or early 2009) from this long, long awaited machine. In the meantime, lots of other warm-up test will be going on too. Link here for more.

For more on the LHC and why we care, see several older posts here (this one links to lots of things), including the ones pointing to the nice NPR pieces (here, and here).

Not a Free Lunch

Yesterday saw a mass desertion for a while here at the Aspen Center for Physics. Howie Haber (UCSC) organized a large group (twenty-two) of participants (and some of their guests) of the program entitled “LHC: Beyond the Standard Model Signals in a QCD Environment” (info here), to go for a group lunch at the excellent Pine Creek Cookhouse, 12 miles away up Castle Creek Road. And, I should mention, 1700 or so feet up. The latter is significant since about two thirds of us, led by Howie, cycled up there! It takes a while (times ranged from 1 hr 20 minutes to about 30 – 40 minutes more than that), and there are about two or three major long, punishing hills to deal with, but it was worth it!

Here are some (not all) of the cyclists at the destination (restaurant is a low-slung cabin-style affair out of shot to the right). Howie, our organizer, is in the middle at the front. (Click for larger view):

(Er, for the record, I’m slightly embarrassed by wearing socks with my sport sandals – a personal no-no – but I wanted to protect my feet from 12 miles of pedalling friction, so made an exception.)

Inside CDF!

Comments Off on Inside CDF!

There’s a new website that allows you to tour CDF, the particle physics detector at Fermilab, in Illinois. Jenny Lee, who worked on the site, said that it is:

CDF detector, Fermilab“a sort of `virtual tour’ that takes the viewer through each section of a particle detector, and includes photos, interviews with physicists, and more”.

The link to it is here. It looks great. Go and look, and spread the word about it!

P.S. While we’re on the subject, did you see the videos that take you inside the ATLAS detector inside the the soon-to-be-operating LHC? I posted about them here. Have a look. Click to continue reading this post →

Libby Lavella, performing at Categorically Not! 8th June 2008

Tonight’s Categorically Not! event was rather good fun, and interesting too. There were three excellent presentations under the theme “Ambiguity”. (See here.) K. C. Cole did a great job in bringing these people together (and of course in acting as M. C. on the night).

Bart Kosko did a great job talking principally about “fuzzy” mathematics, contrasting it with more binary (if you like) systems of logic. I think that his overview was great, and he talked about all the grey areas in logic and questions of epistemology where a “fuzzy” system is needed.

Pauli’s Other Principle

By | | ,

Do you know about Pauli’s Other Principle? One statement of it is:

Fermions are discovered in the US, whereas bosons are discovered in Europe.

(In case you don’t know, it is useful to classify particles according to whether they come with integer (0, 1,2,…) multiples of a basic unit of spin, or half-integer (1/2, 3/2,…) multiples. Fermions include the electron and the quarks, bosons include the photon and the gluons…)

Jester at Resonaances examines the striking evidence for the Principle in modern particle physics, and examines some of the predictions that follow from it. It was clear from the principle, for example, that the SSC (Superconducting Super-Collider) in […] Click to continue reading this post →

John Howe’s Glorund vs Turin imageWell, I’ve said (and pointed to) enough on the matter, but I could not resist a quote from today’s essay by Dennis Overbye in the New York Times (do have a look at the rest of it):

Besides, the random nature of quantum physics means that there is always a minuscule, but nonzero, chance of anything occurring, including that the new collider could spit out man-eating dragons.
