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.

Reconfiguring

usc campusWell, it is the first day of the new semester here at USC, and of the new academic year. Whether I like it or not, everything changes today, in terms of my work patterns. I have to squeeze the sprawl of my research (recent posts about that here, here, here, and here) back into a more confined space to make room for other things. Chief among those is my Physics 151 class, where I teach about 90 freshmen (science and engineering majors) the ins and outs (but mostly the ins) of mechanics and thermodynamics. I’ll also be dealing with a number of service and outreach projects that I’ve had on hold for a few months, and, of course, I’ll be serving on a number of committees doing various things in the department and the university at large.

Am I ready? Not entirely. I’m not fully in the right frame of mind, it has to be said. The various research projects I was working on did not get as far as I would have liked, and I could benefit from more of the full-immersion mode that Summer affords in order to follow up lots of ideas and computations. Also, there are entire projects I did not even get to.

But you do what you can, and that’s all there is. I’ve been dumped into a weird time […] Click to continue reading this post →

Summary Strings

I don’t know if you saw it, but I happened to catch the last two talks of the Strings 2008 conference, via live webcast. They were summary talks. Hirosi Ooguri did an excellent job of summarizing all the main themes in various talks during the conference, and the David Gross summed it all up, took stock of where we are, and where we aren’t, and looked forward. A sort of “state of the union” speech if you like. And the state is good. Very good indeed.

I found these two talks to be excellent, informative, and very interesting. I recommend them to people interested in research in strings and related topics. I can’t see a link to […] Click to continue reading this post →

Welcome Invasion

paraphenalia for discussion magnetism

“Invasion” in the sense of something that took me away from my regular time usage, I should say. I just spent an interesting period of time this morning viewing a pilot for a new TV show. It has a large science component, and will be on one or other of the Discovery Network’s channels. I appear in it (talking mostly about magnetism), and I blogged about some of the filming of it here.

I have to say it was a pleasure to spend a bit of time looking at the (nearly) finished product and commenting here and there on the script and so forth. The concept of the show is really good, and they manage to carry it out with humour while still getting […] Click to continue reading this post →

Susskind and Cole on C-Span2

I just happened (while flicking channels to try to avoid the naked mud-wrestling, oops, women’s beach volleyball*) to run into a broadcast of the Los Angeles Public Library conversation between KC Cole and Lenny Susskind about the amusingly titled “Black Hole War” between him and Stephen Hawking and the circle of ideas and theories connected with all of that wonderful area of physics. (I blogged about it here and here.) It looks like it was really good (I just caught some of the questions and answer […] Click to continue reading this post →

Some Science With Your Politics

Well, there’s all sorts of rhetoric on all various matters from the main presidential candidates, and there’s still a long way to go until November. It’s nice to hear a bit of chatter about global warming, gas prices, research into alternative fuels, cars with higher efficiency, and other issues that have a high degree of science playing a role in shaping our decisions about our policies and actions, in all aspects of society. (Although there is some occasional mention at some points at state level, it would be nice to hear a lot more about concerted thoughts about public transportation infrastructure, but perhaps that’s just way too much to ask in a society still rather naively obsessed with individualism at all costs.)

So what are the official positions of the candidates on science, across the board? Well, […] Click to continue reading this post →

E.Coli Stories

By | | , , ,
4 Comments

e.coli image from http://www.foodpoisonblog.com/Not long ago, science writer Carl Zimmer spoke at the Zócalo series. He was talking about the subject of his new book, E. Coli, and wove a lovely story of how the E. Coli have taught us so much about life over the years, and how they continue to do so. So much of what we know about the workings of DNA, for example, came down to studies of a very clear model system, and E.Coli was the system chosen by Biologists (and Physicists interested in fundamental issues surrounding the nature of life, DNA, etc.) (Updated attribution: Image left is a painting from here. Worth looking at that site for more such images.)

The talk, for a general audience, is highly informative. It is only about an hour long, and worth your time. It was broadcast last night, and I found it rather good indeed. I […] 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). Be sure to watch the excellent videos showing you the inside of one of the detectors (links in […] Click to continue reading this post →

Experiment IV

Ok. Time for a bit of fun, or something. It’s rainy here, and I’m waiting for things to dry out before I go home. I’m between tasks, and I’m woozy from that extra beer at the weekly picnic (thanks, Ben!) so that’s my excuse. Not that I’ve ever needed one.

The other day while hiking I found myself singing Kate Bush songs. No, really. I get into a Kate Bush mood sometimes. Deal with it! Anyway, “Experiment IV” sort of stuck in my head and went around several times. It’s all about a science experiment, even if only a slightly naive exploration of how the military exploit scientific research. I simply love the way she made the phrases “We only know in theory what we are doing” and “We recorded it and put it into our machine” work with the rhythm and melody lines. Then I remembered, and checked on YouTube, how she’d construct these really excellent videos which were miniature movies, telling a little story, at least two of them (this song, and “Cloudbusting”) involving scientists.

Kate Bush, Experiment IV performance (still)Now of course, the scientists were the usual men-in-white-coats scientists (however, the image right is explained below). I know I go on a lot about trying to have in the media a wider variety of images of what scientists can look like, but that does not mean that I don’t like things that sometimes have the old chestnuts. Cloudbusting has Donald Sutherland as the scientist-father-figure, and Experiment IV has a similar figure (played by someone I don’t recognize) as the scientist whose work is exploited. There are a number of actors in supporting scientist roles too – look out for (I think) a […] Click to continue reading this post →

Draw

game of naughts and crosses, spotted in the bar/lobby of an Aspen hotel.I’ve been quiet here recently, I know. Was mostly working, thinking and reading on the weekend. Did not even go on a huge hike (although I did do a nice walk or two). Sometimes, on an evening, I go and read a novel in a bar. (I’m weird that way, I know.) I’ve not been going to the noisy bars full of yelling and the party crowd, but instead like to find a nice sofa in one of the bar/lobby areas of the nicer hotels. Great for reading, and the drink prices are merely extortionate, as opposed to just plain offensive in the more popular places. (Photo: a naughts and crosses game I spotted on a table in one such lobby.)

Well, it’s a draw so far in the battle with my equations and ideas, but I think I’m developing a stronger position. (From this you can deduce that I decided to stick with the same project and hold my ground and struggle on some more.) Perhaps the next […] Click to continue reading this post →

Quantum Black Holes – Why Worry?

susskind_by_matthew_black for LA TimesWell, you may not have gone to the chat between K C Cole and Leonard Susskind that I mentioned a while ago at the LA Central Library downtown. I couldn’t make it either, being away at the Aspen Center for Physics. I expect it was good. Anyway, I found a little bit of a report on the conversation, done by reporter John Johnson for the LA Times. It is here. (Clickable image of Susskind to the right is by Matthew Black, for the LA Times.)

It gives you some of the simply-stated reasons as to why there was a big argument between Stephen Hawking and Leonard Susskind in the first place (and between several other physicists too… there are hosts of people working on these things, and it took hosts of people to sort it out to where we are now, not just those two, giants though they are). I recommend having a look, as it is especially for the lay-person, and will give you a good idea of what the fuss is about.

You can also see a little bit about his new book on the subject and a link to a video interview with Brian Cox (the physicist, not the actor) at the LA Times blogs here. There are also links to his Stanford continuing education course on quantum mechanics, including the online lectures you can view at your convenience. What a resource!

You might wonder why we care about all this, since currently the only way we know for sure to make black holes in the universe (astrophysical processes making stellar black […] Click to continue reading this post →

For Some, The Dark Side

solar_eclipse_010808Don’t forget that there is a total solar eclipse tomorrow. Been wondering where the moon’s been, and why you’ve been having all those lovely clear dark nights perfect for star-gazing? Well, the moon’s been busy preparing for one of its big acts. It’ll pop in front of the sun and bring a little darkness to some regions during the day tomorrow. Put differently, the dark side of the moon will be stealing some of our rays on August 1st.

Who will get to see it? Well, full totality will be available mostly for the “midnight sun” […] Click to continue reading this post →

Humps

Now playing: I’m Confessin’ (That I love You), Thelonious Monk [Solo Monk]

Well, I’m now beyond the halfway mark of my retreat and I’ve been on the one project all this time. I’ve made progress here and there, had some setbacks, and have got very stuck at times. It’s just one of those things with this sort of work. Par for the course.

humps in road warning sign, UKThere are times when you think that if you do just a bit more on the project, it’ll get over the hump, as it were, and then coast along. So far I worry that there may be simply an infinite set of equally spaced humps of similar height all the way down the road**, in that every now and again I discover a rather pretty little gem of a result that’s quite encouraging, but these gems don’t seem to have anything to do with each other. So it’s a little scattered gravel pit of gems as opposed to a lovely… Ok, cvj, enough with the gem metaphor.

Tales From The Industry XXI – Another Go At An Einstein Film

By | | , , , , , , ,

Well, since they’ve actually done a press release about it, I suppose I don’t have to be so coy as I was in the last post. This is about the film company I was doing some consulting work for on an interesting project with and interesting screen-writer.

The company is called Hero Pictures, and they have an interesting mission statement, and a rather splendid website (which I recommend… love the little hero guy) which tells you more. One of their projects is a film about Einstein. Working title is “The Private Lives of Albert Einstein”. They’ve bought the rights to a couple of books on him, brought in a screenwriter (see my thoughts on him and working with him in the previous post), Ron Bass, well known for his work on projects like Rain Man and The Joy Luck Club, Snow Falling on Cedars, among many other films.

It was fun to work with him on this, however briefly. He’s super sharp and gets the […] Click to continue reading this post →
