joke hollywood star of brian greene Sometimes the journalists and editors get it right. In fact, they get it right a lot of the time, but you hear more about the complaints (sometimes from me, sometimes elsewhere) about them getting it wrong, when it comes to things like science coverage especially. What am I talking about? I’m talking about the set of questions and answers that are in a new article on MSNBC that a number of people pointed out to me yesterday and today. It starts out as an article about Brian Greene’s science outreach efforts (books, and tv and movie appearances, including a new one), with some discussion of how this is regarded by his colleagues, the value it has had in raising public awareness of physics (and fundamental science in general, I would argue), and so forth. All that is interesting, but not nearly as interesting to me right now as the later parts of the article which is simply a question and answer session. (Picture above right is from a fun joke I carried out last year that you can read here – be sure to read the comments too.)

Alan Boyle, the science editor, asks Brian a series of very thoughtful questions, and Brian gives some very thoughtful answers. The topics include research in string theory (of course), hopes and possibilities for experimental and observational results (such as from the LHC and Planck) that can inform and ultimately test the ideas coming from string theory and open up new vistas in fundamental physics, research on issues such as the landscape, the idea of multiple universes, research on better developing our understanding of string theory (to the point where we can, it is hoped, extract firm predictions from it), and many other things. (I wrote an introduction to aspects of the landscape issue here – see also the comments – and talked a bit about a Tom Siegfried article on the discussion amongst researchers here.)

It is nice to see an honest, non-inflammatory and non-hyped conversation about the issues, and read Brian’s personal take on some of these matters. The bottom line is, Click to continue reading this post →

So on Wednesday night while cooking dinner I was listening with half an ear to Talk of the Nation, on NPR, and at some point found that I was listening to a discussion about robots. They were talking to Lee Gutkind about his new book about robots, and about the future, and robots as tools, and interfacing with robots and so forth. All very interesting, all bruno robot made somewhat more engaging by the very deliberate way the interviewee spoke, taking great care with every sentence he uttered. This feat rather kept my attention more than the material, which I’ll hasten to add was not uninteresting -and certainly a topic I spent a lot of my youth dreaming about especially given all the Asimov books I used to devour- but my focus was elsewhere I suppose. You can listen to the program here, and it is all certainly worth thinking about, it is a very serious and important topic, and robots (although mostly not in the form we see in our dramas on tv and in the cinema) may well dominate our society the way computers have become so central to us right now… so go right ahead and listen to what he has to say.

What finally grabbed me, this time, was not the serious “issue” material. It was this: Click to continue reading this post →

Categorically Not! – Vulgarization

By | | , , , , , , ,

The next Categorically Not! is Sunday 25th March. The Categorically Not! series of events that are held at the Santa Monica Art Studios, (with occasional exceptions). 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. There’s a new website showing past and upcoming events here. You can also have a look at some of the descriptions I did of some events in some earlier posts (such as here and here), and the description of some of the recent special ones on Point of View and Uncertainty that I organized with K. C. as USC campus events (here, here (with video) and here).

Here is a description from the poster for the upcoming programme:

E8 and the Gosset polytope 421

No, not another flower from my garden. This is a two dimensional projection (originally hand drawn in the 1960s by Peter McMullen, of a polytope that lives in eight dimensions, known as the Gossett polytope 421.

Trying To Tell Me Something?

The other day I was making one of my (half-) joking “kids today” mini-speeches to one of my (very patient) graduate students, Tameem, as part of an IM chat we were having about graduate teaching matters. He then said that he remembered something he wanted to share with me, and IM-ed me this*:

Candace Partridge: Women in Physics at USC

By | | , , , ,

Rather than just sit around and wring our hands about the severe underrepresentation of women and minorities in science and engineering, it’s worth getting out there and trying to do things to help make a change. Here at Asymptotia, I describe things of that nature from time to time. At other times, I like to just shut up and listen, since (for example) it is also important to hear about the opinions and experiences of a range of different people who are trying to make their way in some aspect of these fields.

candace partridgeToday we have a guest post from Asymptotia regular commenter Candace Partridge (clickable image on right). Candace is doing an undergraduate degree in Physics at the University of London (Birkbeck College), having come to study the subject at this level rather later than is traditional, and having studied other subjects, and worked professionally in another career. This gives her an unusual perspective, and one that is of considerable value. Candace attended the Women in Physics conference that was held at USC in January, and of which I spoke earlier. She tells us a bit about it below, along with some thoughts about her own path in Physics. There is some overlap with an article she wrote for Inkling, but Candace has expanded on several aspects for her post here.

candace tripAhhh…what’s better than a trip to LA? How about a travel grant to get to LA to attend the 2nd annual Undergraduate Women in Physics conference held at USC? Most students view MLK Day as a sort of bonus extension the to holidays, a way to ease back into the usual routine. However, for 50-odd physics students, this long weekend was a chance to make the journey to USC to meet other female (and a few male) physics students.

Of course, where I’m now from (London), we don’t get MLK day off. In fact, I was only on native soil because I had cleverly timed a three-week trip to visit my parents in Mississippi to coincide with this conference. After all, once I’ve flown 5000 miles, what’s a couple of thousand more? No problem! I landed in LAX to bright and sunny weather but with a cold wind blowing out of the north, heralding the arrival of that cold wave that destroyed the citrus crops and brought snow flurries to Malibu. It was far colder in LA than in London that weekend.

candace tripThis was my first trip to a physics-related conference, and I was a wee bit out of the target demographic. See, I am still a lowly undergrad — I say ‘still’ because here I am a woman pushing thirty who is barely halfway through her BSc as opposed to the young striplings a full decade younger than myself. Also, I was the only attendee from overseas…kind of. But I am happy to mix with people of all sorts, especially other women like me who are studying physics because, let’s face it, some of us are still feeling a little alone over here.

So I’m a female mature student, which in undergrad physics makes me a bit of an Click to continue reading this post →

tomato on stepssurvivor tomatoHere’s some remarkable news from the garden. You may remember that last April I noticed a tiny tomato plant growing out of a crack in some steps, and that I promised to keep an eye on it? (Picture, left.)

Then later in July I reported that not only had it survived, but it produced tomatoes? (Picture, right).

Well, it just continued on through the cold spells we had here this Winter, and some weeks ago I noticed that it had tomatoes on it again! This is a shot I took today: Click to continue reading this post →

More Scenes From the Storm in a Teacup, VII

By | | , ,
175 Comments

You can catch up on some of the earlier Scenes by looking at the posts listed at the end of this one. Through the course of doing those posts I’ve tried hard to summarize my views on the debate about the views of Smolin and Woit – especially hard to emphasize how the central point of their debate that is worth some actual discussion actually has nothing to do string theory at all. Basically, the whole business of singling out string theory as some sort of great evil is rather silly. If the debate is about anything (and it largely isn’t) it is about the process of doing scientific research (in any field), and the structure of academic careers in general. For the former matter, Smolin and Woit seem to have become frustrated with the standard channels through which detailed scientific debates are carried out and resolved, resorting to writing popular level books that put their rather distorted views on the issues into the public domain in a manner that serves only to muddle. On the latter, there is a constant claim that string theory and its proponents are somehow brainwashing and/or frogmarching young people into working on that area to the exclusion of all else. The authors seem oblivious to some simple facts to the contrary there: (1) that you simply can’t do that to genuinely smart, creative young people; (2) that even students who have string theorists as their Ph.D or postdoc advisors often work on non-string theory research topics (3) that they’re doing an excellent job of either driving young people away from working on some of their favourite alternatives – or from pursuing theoretical physics altogether – by failing to clearly explain their merits and by using the press to help turn this into a distorted spectacle.

I’ve summarized a lot of what I think in the latter part of this post.

There are two major problems with how live debates take place in the public sphere. One is that the average person listening to the debate cannot know whether much of what Smolin and Woit claim as facts are right or wrong (or anyone on the other side of the debate, for that matter). When someone disputes a claim that Smolin makes, he Click to continue reading this post →

When Worlds Collide, II

I think I ought to explain, as promised, why I am in New York. The first thing to mention is that I wrote the previous post in this miniseries (it was written on a flight to Dublin, and finally posted when I returned) before I knew about any of what I’m about to tell you, so it is rather funny to me…

casino royale shoot

The week that I returned from Dublin I noticed a phone message from an editor of a magazine asking me to return their call. A couple of days later I learned what it was about. It’s a magazine that largely focuses on buzz about people and projects in the entertainment and fashion industry – Music (R&B, Hip Hop mostly), Movies and TV, etc., as far as I can tell, along with some coverage of parts of the business world. Its readership is mostly younger African American males, I think. As far as I can tell, the intention is not to be about those things in particular, but it is largely reflecting the interests of the readership it is targeted at. It’s a major product, jumping out at you immediately when you are in the magazine store (the striking picture of a woman on the front helps it grab your attention, of course).

Each year, the magazine does a special issue featuring a group of individuals who are doing “major things” in the industries I mentioned above. It is a combination of a focus on new talent that’s about to become more widely known, or just bringing to readers’ attention the existence of some of the people who are making significant impact in what they’re doing.

Somehow – I do not know how – they got my name. It turns out that they spent some time reading some of things I’ve written here at Asymptotia too. Now normally, you’d expect things to stop at that point, but in fact it did not. They decided to broaden things out a bit and include me (if I was willing) in this year’s feature issue.

I thought about it for a day. It is quite an honour to be approached, and I’m also impressed that the magazine’s editors are being creative in this way (it would be easy Click to continue reading this post →

So Good They Named It Twice

empire state buildingI’m referring to New York, of course. The Empire State building, which I walked by a short while ago, is still pretty lovely (it has to be said that I’m more of a Chrysler building man, myself – must go and have a look for it).

It’s been several years since those days when I used to use New York as my Summer base camp, and it’s been too long. Four or five years, I think. I’d forgotten how much I missed the city, to be honest. It is certainly good to be back and see it all again, including the bitterly cold wind that can be channeled down the grid streets with the bits of snow side by side underfoot.

The city is even greater in my mind now that you can so easily connect to the airport using the subway, train and the AirTrain. (As I’ve discussed in other posts I am sure the same enhancement (but massively more so) will happen to Los Angeles when the new subway/train lines are built).

Thoughts from Above, II

[Written a few hours ago on a plane. Later uploaded for your consumption.]

So I’m continuing my thoughts about plans for the Summer. You probably ought to read part I first. This post is also a bit of a ramble. I was thinking a bit more about Spring/Summer travel, you see. There’s a thing I ought to do one of these days which nobody in the field seems to ever do as a Summer travel option:

Why not go back to school?

Students and young postdocs in my field often go to long schools where there are lecture courses in various aspects of a particular topic or selections of topics. Somehow, faculty don’t seem to go to these, and I don’t know why (unless they are lecturing part of the school and sit in on some other lectures, which I’ve done, and it’s always instructive). It is as though there’s some sort of stigma – perhaps we are all supposed to pretend that we know all that stuff and so can’t be seen sitting in a classroom taking notes. But these lecture courses -when done right- are a perfect combination of the basic techniques and the most contemporary results, which can be rare material, and I know of nobody in the field who can honestly claim to be fully in Click to continue reading this post →

Thoughts from Above, I

[Written a few hours ago on a plane. Later uploaded for your consumption.]

I find myself on a plane to New York (sort of) all of a sudden. I’ll explain later what it’s all about, since I do not yet know to what extent I’m allowed to blog about the details. Let’s just say that it involves dusting off the tuxedo (I can’t recall what we called them in England..dinner suit?) that I bought a couple of years ago. I’ll leave you to guess, if you like, what on earth could involve being thus attired during the daylight hours.

About the tuxedo: I’d decided back then, while preparing to be one of the blushing recipients at an award ceremony, that I’d buy a decent one and get it tailored to fit properly rather than continually rent ones that don’t quite fit right. I decided to gamble that – given the town I live in, where the cold Winter Season is replaced by an Awards Season- it makes sense to own one, especially since my suit measurements have not really changed for the last 20 years or so1.

This blog post is not about anything in particular. It’s really just some random thoughts passing through my head as I fly over the… Oh. well, it was desert last time I looked. But now it’s just cloud, so I’ve no idea what I’m over. A cloud-covered bit of desert, I expect.
