Images From Afar

extrasolarplanet orbiting starThis is quite remarkable. There’s actually been an image (see left) taken of a planet orbiting another star. There are hundreds of known extrasolar planets in orbit around other stars (see lots of earlier posts), and evidence for them has been indirect, since they are too tiny and too dim (having no light of their own) to image directly. You can learn of their existence by their effects on their parent star, and/or on the light it casts. (The image left is courtesy of the Gemini Observatory. The University of Toronto scientists used the Gemini North telescope on Mauna Kea in Hawaii and its adaptive optics technology to make the image.)

But this is different, and a bit of a milestone. These astronomers released an actual […] Click to continue reading this post →

The next Categorically Not! is on Sunday September 14th. It’s the start of the new season! The Categorically Not! series of events that are held at the Santa Monica Art Studios, (with occasional exceptions). Libby Lavella performing at Categorically Not! June 8th 2008 It’s a series – started and run by science writer K. C. Cole – of fun and informative conversations deliberately ignoring the traditional boundaries between art, science, humanities, and other subjects. I strongly encourage you to come to them if you’re in the area. Here is the website that describes past ones, and upcoming ones. See also the links at the end of the post for some announcements and descriptions (and even video) of previous events. (Image on left is of artist and musician Libby Lavella, in her presentation about ambiguity in art and music during the June 8th 2008 event.)

The theme this month is Bubbles. Here’s the description from K C Cole: […] 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 →

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.

One in the eye for Big Textbook?

By | | , , , , ,

Well, back to teaching issues. Textbooks. I know the following is illegal, but I will admit to being hopeful that this will supply a much needed kick in the rear end for the “textbook industry”. (The very term makes me a bit ill sometimes.) In teaching the big courses at freshman or sophomore level to classes that have a couple of hundred students (broken into sections – we don’t like super huge classes here at USC) enrolled, it is hard not to notice that there’s something slightly insidious about aspects of the textbook game. Despite the fact that we are teaching subjects (Newtonian physics, thermodynamics and a brief bit of “modern physics” that is mostly from no later than 1905) at levels that have not significantly changed for over a century (in some parts, several centuries), the Industry (shall we call it “Big Textbook”?) keeps finding new excuses to come up with new editions. These editions get more and more expensive, and heavier and heavier to carry around. I don’t know why this is necessary, except to force new students to buy the books all over again.

Additionally, the new hook is to combine the book with an access code for further […] Click to continue reading this post →

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 →

Help Me! Heeelp Meee!

the fly operaSorry. Didn’t mean to cry wolf, but I always think of that great (as in camp and amusing) ending scene when I think of The Fly. The movie, anyway. (That’s in the original 1958 movie version – clip at bottom of this post.) Now there’s an opera! I am not joking. David Cronenberg has teamed with composer Howard Shore to create an opera. (You know the work of both of them rather well, actually, from film work together, and separately – Shore did the wonderful music for films such as The Lord of the Rings trilogy, and Cronenberg the film director needs no introduction.) I love the play on Da Vinci’s iconic drawing for the production’s publicity and so forth. See above right.

The artists are of the opinion (and I agree, in principle) that the themes visited in the story are powerful and resonant enough for an opera. Science, science ethics, new technology, fear of same, mercy killing… and presumably devotion to a cause, […] Click to continue reading this post →

A Farewell To Arms

cut off arms from shirts

When I look at this, it sort of scares me a touch. Just a touch. There’s a memory of the arms – flesh and blood ones – inside them, and there goes a shiver down my spine. But it’s all fine, really. There’s nothing sinister going on, and no horrible subtext lurking at all. What I was doing with my Labour Day holiday was all perfectly innocent. Nobody’s arms – not mine or anyone else’s – were or will be hurt! (I’m rather pleased with the title of the post, I have to say.)

Glory

morning glory The battle is in full swing, and it is a rather glorious one indeed. What battle? Well, I deployed some ground troops of legendary tenacity to do battle with some ground cover of relentless ivy. I don’t like the ivy much. Since it keeps coming back, and since there is no end to its inventiveness at returning and spreading, I decided to try a different tactic that I knew would have certain other benefits. Deploy the Morning Glory.

I remember my first true appreciation of the powers of morning glories. I was an assistant professor at the University of Kentucky living in a nice cabin with a nice bit of back garden, not far from campus, in Lexington. I’d spend my Summers in New York back in those days. One late spring I planted some morning glory seeds, and watched the little plants that resulted struggle through the dirt and face the sky. Then I was away for the Summer, on my usual (for the time) retreat to the excellent Morningside Heights neighbourhood, the whole of Manhattan my office.

Upon returning to Lexington, finding everything still in the clutches of the humidity that reigns supreme at that time of year, ready to begin teaching in the new […] Click to continue reading this post →

Big?

On campus yesterday, I ran into a colleague I had not seen in a long time. She was with her daughter. She introduced us, saying, among other things, that Professor Johnson is “Big in Cosmology”.

I’ll admit that I giggled like a naughty schoolgirl for a longish, unprofessorial moment. It was sort of hard to explain, and would have derailed the conversation, so I did not try. Why was I giggling? Well, it is just that the field of cosmology (which, for the record, […] Click to continue reading this post →

GLAST, Fermi, and Early Results

Comments Off on GLAST, Fermi, and Early Results

Well, the new orbiting instrument, GLAST (Gamma-ray Large Area Space Telescope – launched June 11th this year) has passed all its tests with flying colours, apparently, and is working well. NASA has now renamed the craft the Fermi Gamma-ray Space Telescope, after Enrico Fermi. There’s a press release here.

The craft is a wonderful combination of the fields of particle physics, astrophysics and cosmology, and will teach us so much about the universe (such as the nature of dark matter), and so it is exciting to hear that it all on track.

Excitingly, they’ve also released images of the early results of the observations, and you can read more about them in the press release too. Here’s a sky map made from the observations.
