Becoming Engaged…

It turns out that a really great way of passing the time when listening to someone give a talk is to do some sketch practice. [… wait, what? The post title? Oh! No, no, don’t be silly. Ok., let me continue …] If the subject matter is right, it’s a good thing to do while you focus on what’s being said. This last couple of days I’ve been in Aspen, Colorado, and I’m starting out my visit here with a three day conference entitled “Becoming Engaged: Initiatives That Can Change Science Education”. You can see more about it on a dedicated website hosted by ICAM. One of the people behind it is David Pines, and we’ve had many conversations about science outreach and science education over the years, and so he invited me to participate. I’m supposed to be here at Aspen for my visit to the Aspen Center for Physics, and so I’m only partially attending, opting to to listen to some talks, and take part in some discussions… then going back over to the center to hear some LHC and Higgs chatter on the LHC workshop that is starting up this week.

There are a lot of interesting people talking about science education, and science outreach, many describing their various approaches and projects in short talks and presentations. (I will tell you about some of them in future posts.) It is great to meet several people who are passionate about outreach too, and see what others are up to and share ideas… so this is a valuable time. Hopefully, some action ideas will come of this meeting that […] Click to continue reading this post →

Voice of God

With the Aspen Center for Physics film almost completed (see several earlier posts, e.g. here, here, and here), various things get set in stone once and for all, so that other things can be built on top of them. At some point, I had to be certain of the final form of the voice over, so that Dave (the editor) can lay it in and time various transitions around it. This was done on Friday along with a huge rewrite of the whole film script, and lots of work on picking b-roll footage and other material to illustrate the film and create atmosphere. Once my co-producer/director Bob had glanced at it and made some helpful remarks (always good to have more eyeballs to spot any mistakes that could get frozen in) I was ready for Monday’s exercise – recording the final voice work. No turning back, no second chances, since we need to deliver the film this week.

While I’ve directed a bit before, I’ve not ever had the chance to direct a hugely experienced star actor, so this was going to be a blast! A while back, over food and drink at a party, my friend Harry Lennix (who loves contemporary physics – that’s in fact why we met, years ago) had generously agreed to do the voice narration for this project, and I was very pleased since it was his voice I had in mind since late August […] Click to continue reading this post →

Peek Over My Shoulder

Been splitting my time between being a physicist and being a filmmaker making a film about physicists. It has been an interesting time. Recall from earlier posts (see e.g. here and here) that I am working on getting a film made for the Aspen Center for physics in celebration of its 50th Anniversary. I’ve got rather sucked into the process – a lot more than I intended – and so find myself putting together the script that will guide the editor in cutting the film. This means that I’m reviewing acres of footage of interviews and picking out some great quotes from my awesome cast of interviewees. You might recognize some of them (feel free to try to name them, and their field…).

Film in Progress…

This was an incredibly busy visit, but worthwhile. We pulled 12+ hour days in getting everything needed for the film (about the Aspen Center for Physics), with lots of backup, and oodles of great footage. So much that I fear we have so much great material we can make five completely different short films instead of the one that is supposed to be delivered. It is going to be tough. I’m so excited about some of the things that we’ve shot. A number of ideas I had for the arc of the film, the feel and tone, and the opening moments, look to be falling together almost _exactly_ as I envisioned them months ago.

Ouf excellent DP, Dave Gaw, (an accomplished filmmaker in his own right) seems to almost immediately get what I’m trying to do when I explain something I’ve visualized, or when I draw it, and so the shots work out quite nicely, and sometimes he’s gone and filmed some sequences that look very much like ones I’d been imagining, sometimes without us even having had a discussion about it! It has been a great collaboration among the three of us – Dave, Bob Melisso (my co-Producer/Director), and myself – as we exchange ideas about how to best implement something or other to make it tell part of the story…

Anyway, while preparing for getting some nice outdoor shots of physicists doing […] Click to continue reading this post →

The Shooting Party

20120529-112915.jpgI’m at the Aspen Center for Physics for some time this week. It is a big week. You will perhaps recall that I’m involved in making a short film for the 50th Anniversary celebrations of the ACP (see some earlier posts) and now we are doing another batch of shooting. Not just interviews, as we have been doing so far, but much of the other footage we need, such as the lovely grounds, the various physicists using the center, in myriad ways, and so forth. We’ve had a super long day today, which[…] Click to continue reading this post →

Documenting

Speaking of film projects involving science, I’m involved in two new ones I’ve been meaning to tell you about. I’m working on producing a short film about the Aspen Center for Physics, to be used in the upcoming 50th Anniversary celebrations. My partner in crime on this is Bob Melisso, who I’ve worked with before a number of times, and it’s already been interesting, and fun. I think that the final piece ought to be interesting at the very least. I’ve been trying to work in a very particular look and feel for the film that reflects something about the nature of the work that goes on at the center (both its content and how it is done), and so there’ll be lots of chalk, scribbling on boards, reflections on the creative process and how a place like the Aspen Center helps, and so on and so forth.

We’ll be shooting from time to time over the early and middle Spring, and doing the […] Click to continue reading this post →

Mountainous

As you might guess from the flower to the right, I’m presently not in California, but Colorado. In fact I’m in Aspen, a place to which, you might have gathered from previous years’ blogging, I come to work for a while in the Summer. The Aspen Center for Physics is here, as well as some great mountain trails, river walks, bike trails*, several other organizations of interest, festivals, and of course, some good cafes. So I’m pretty well set up in terms of things I need to think and work on various projects.

The flower is the columbine, the state flower, and I encountered them (and a host of other lovely flowers of many types) on Saturday on my first hike since properly being acclimatised to the altitude and so forth.

I’ve already had some great conversations at the Center, which included catching up […] Click to continue reading this post →

Summer Reminder

aspen center for physicsThis always catches people off guard (myself included), so I thought I’d post a little reminder. The deadline for applications to the Summer workshops at the Aspen Center for Physics is January 31st. That’s coming up soon, so to physicists interested in doing a research stay, start thinking about the dates you want to attend, finding funds for support, planning for things like childcare or summer programs for children if you have any, and so on and so forth. There’s a wide variety of excellent […] Click to continue reading this post →

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.)

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 →

News From The Front, V: Microscopic Weekend Diversions

By | | , , , ,

I’ve been spending the day so far as an administrator, and not a researcher, since I have to present the results of two committees’ deliberations at one of the big annual organizational meetings tomorrow here at the Aspen Center for Physics. So I’ve been gathering and arranging data in a presentable form. Enough. I will take a break and blog a tiny bit before turning to a truly riveting task – reviewing an introductory physics textbook for a publisher… (Sigh…it is not so easy to escape these things out of semester time.)

I had big plans to do a hike each day on the weekend, but physics intervened. I should explain a bit more. Earlier last week I eventually got around to following Nick’s suggestion from an earlier post to take a look at Andy Strominger’s Strings 2007 talk entitled “Search for the Holographic Dual of N Heterotic Strings”. It was the usual nice Strominger talk, where he motivates the physics very well, and presents interesting and clear D-branesthoughts on the problem in hand. I shall try to say a bit more about what it is about later on, but the general gist of it is that it is to do with understanding certain types of four dimensional black hole in string theory. As you may know, one of the extraordinarily successful results in string theory in the last decade (and slightly more) has been that we can understand one of the most central results of semi-classical quantum gravity -that they have an entropy and behave like thermodynamical objects (the work of Bekenstein and of Hawking from the early 70s)- in precise terms in the full theory of quantum gravity that string theory appears to present us with. This started with the work of Strominger and Vafa in 1996, that showed how to describe a large class of black holes as essentially made of extended objects called D-branes (about which I’ve spoken at length earlier1).

Just to fill in the gaps roughly: Hawking’s result that black holes can radiate as thermodynamical objects comes from taking Einstein’s theory of General Relativity and combining it with Quantum Mechanics in a partial way. He could not really do much better since there was no proper quantum theory of gravity at the time, but even in […] Click to continue reading this post →

More Than A Hint Of The Old Days, II

By | | , , , ,
18 Comments

A strange but satisfying aspect of my time here (I’m at the Aspen Center for Physics, recall) has been the fact that due to some odd serendipity, there’s a ton of people from the “old days”. Which ones? My Princeton years, in the early 90s, as a postdoc at the Institute for Advanced Study (and later at Princeton University). These are not all people doing what I do, but in a wide range of fields such as high energy physics, astrophysics, condensed matter physics. Several of us were postdocs together. I’ve been chatting with people I’ve not seen for a while, sometimes not since those days, or they are people I met back then, and with whom I have a pool of shared memories from those days. So it has put me in mind of those times somewhat.

A quick example. Soon after I arrived last week, I was walking along, chatting with Petr Horava (Berkeley) about various things, and we got on to reminiscing a bit about our time together as postdocs in Princeton. And then minutes later, as though conjured from the very substance of our conversation, who should walk by but one of the Gods/Legends of the field (then and now), Princeton’s Alexander Polyakov. He walked by in exactly the same sort of way he would back then, either coming from or going to a walk along the river or canal, perhaps to give us a lecture. Petr and I looked at each other, and continued our walk and talk.

The great news for me last week was that Polyakov then gave a talk. I’ll admit to being a big fan of his physics. When he gives a talk nearby, I show up, no matter how confused I might end up at the end. There’s going to be good stuff in there – it’s only a matter of time before it sorts itself out in your head. Often years. Decades. Several of us sat in on his graduate class back in Princeton in the early 90s just to try to catch the pearls of wisdom which we’d pick up as he lectured on….. Well, I’ve no idea to this day what the class was really about. He would show up (probably fresh from a walk), with no notes or anything, and just pick up a piece of chalk, stare out the window for a few seconds, and then start writing stuff. Essentially, he was randomly jumping around the subject matter in his widely under-read book “Gauge Fields and Strings”. He was all over the book. It was not always a simple and coherent path through the subject matter, and it seemed that he was largely exploring whatever took his mood in the moment, but I suspect that was largely my ignorant young mind’s impression.

The Man of Tomorrow?

[Updated with a bit of video!]

Earlier this week I went for a walk with Nick Halmagyi to chat about physics, and since he had not been down to the meadows and gardens over by the neighbouring Aspen Institute, we wandered down that way. It was just after lunchtime, and a very hot day, and as we got near the Institute, we diverted away from physics so that I could tell him briefly what the significance of the Aspen Institute is. I explained that it was an important “think tank”, host to thinkers in the humanities, sciences, and diplomats, presidents, ex-presidents, and other dignitaries, who come and think great thoughts about the problems of the world. Well, let me use their own words from their website:

The Aspen Institute, founded in 1950, is an international nonprofit organization dedicated to fostering enlightened leadership and open-minded dialogue.

As an example, I explained, it is probably the sort of place that Al Gore might have come to in order to think deeply about the environmental issues he champions. It is nice that the Aspen Institute is right next to the Aspen Center for Physics, and the two organizations, while now independent (but the Center actually grew out of the Institute, see here) sometimes work together on various matters including public outreach. The public lecture I gave here last year as part of the Heinz Pagels Memorial Lecture series (see e.g. here and here), for example, was actually over in the Paepke auditorium, one of their buildings.

We approached the main grounds of the Institute, near their residence buildings, and were greeted by a most frustrating -and ironic- sight. Their sprinkler system was fully on, spraying water unnecessarily into the air and onto the asphalted walks, with some making it onto their lawns, where even there it would mostly evaporate (in addition to aiding the hot sun in scorching the grass somewhat). For once, I did not have my camera and so cannot share this horrible sight with you. For a moment it was as though I was back in LA, but this was Aspen, where everyone talks about the environment. Then I remembered – everyone talks about the environment. At the same time, there are more and more SUVs every time I come here (rental companies even try to force SUVs on you when you try to rent a regular compact car – did you read my story of that last year?), more and more land seems to be cleared to build ever-larger houses, and so forth. On the other hand, bicycle use is very high here, there’s an excellent free bus system, an enforced reduction of individual car access to the Maroon Bells wilderness area, and I imagine several other worthy environmental efforts that I have not seen are being made. So it is a tale of two communities and mind sets. It’s complicated, as with any populate. But you’d have thought the Aspen Institute would be “fostering enlightened leadership” by not watering their lawns and (sidewalks) with vast amounts of water at the maximally worst time of day to do so in terms of effectiveness. (Frankly, given the environmental disaster most lawns are, one could go further and hope that in the spirit of leadership, they’d turn more of their expanse of lawns into other use, perhaps expanding the excellent wildflower garden they have in one corner, or letting more of the surrounding meadows repopulate the grounds. It could be rather beautiful.)

wild flower gardens at aspen institute

Anyway, we shook our heads at the irony of the sight and we wandered off toward the river, continuing our chat about matters in other dimensions (no, really). The next day I came back at that same time to check the sprinklers again (with camera), since such systems are often on timers, but had it rained very heavily the previous night and so -happily- it did not seem that the sprinklers had been used.

On Wednesday I returned once more. The sun was overhead and strong again (not as much as Monday) and the main system was not on. But once again I noticed signs of watering, and saw a smaller component of the lawn being watered by a hose-driven system. I now think that it might be that they were sprinkling (well, gushing) on Monday (and partly on Wednesday) in the mistaken belief that pouring water (and into the air, where it rapidly evaporates) on the lawn while the sun is baking it will somehow help, and they did it on an ad hoc basis, but I can’t be sure. Either way, it is a terrible waste of water resource by an organization that is committed to leadership in matters of importance, such as the environment.

Then I noticed that many people wearing name badges were heading from the Institute toward the direction of the auditorium and the Aspen Music tent. This fit with the next deliciously ironic thing: Al Gore was going to be talking! He’d been at the Aspen Institute (I’d no idea of his presence or the event until a radio announcement on Wednesday morning), and the sprinkler matter, this was remarkable. Convenient, one might say.

It turned out that it was not taking place in the Paepke auditorium, as I thought it […] Click to continue reading this post →

All In A Day’s Work

Difficult to say what a typical day is at the Aspen Center for Physics. It probably varies a lot from person to person, since many people are here for different reasons, and with different goals. There’s a lot of sitting and thinking, and walking and thinking. There’s a lot of chatting in corridors, and at blackboards. There’s quite a buzz of productivity during the middle of the day. On some days, there might be a couple of seminars, where someone presents finished work or work in progress. Here’s Robbert Dijkgraaf (University of Amsterdam) leading a discussion of some of his recent work today:

Strings 2007: Share the Memories

By | | , ,
6 Comments

trees near the aspen center for physicsA big chunk of yesterday (recall, I’m visiting at the Aspen Center for Physics) was spent chatting with old friends in the field I have not seen in a while, including going for a walk or two in the local surrounds with colleagues, discussing some of the physics issues of the day.

One of the things that comes up a lot with everyone I spoke to (and met at lunch, and in corridors and so forth) was Strings 2007, the big annual meeting that was held in Madrid last month (blog post here). It comes up in the form of people asking each other things like: “were you at Strings?”, “what did you think of Strings?”, “what were your favourite talks?”, “is there any interesting gossip about…?” (where the latter is not necessarily directly about physics).

So it occurred to me that some of those conversations and responses might be useful to workers in the field. Of course, you can just sit and work your way through the entire collection of online talks, a good thing to do. But it’s interesting to hear from others what talks they liked, and why, just as we do (and maybe have done) over tea and coffee in lounges all over the world after someone returns from a meeting. Often, this is where we hear of some excellent work by the less famous speakers (or even by someone who did not talk at all), etc.

So I’ll kick off. Although I was not there, and have yet to start a serious assault on […] Click to continue reading this post →
