Some Things That Keep Me Busy

By | | , , , ,

Well, it has been a busy few days. Since Sunday’s activities I’ve been up to my ears in various things. Interesting things, I’m happy to say, and only a few annoying things. Besides getting back on track with life in LA, I’ve been working (with a student collaborator) on various very interesting physics projects that I hope to find time to tell you about soon, involving various applications of string theory of the sort I mentioned in an earlier post.

I’ve also been working on the two films I’m making. They’re now in final iterations of editing, and in addition to working on the iterations writing notes with directions for my editor, I’ve been making some extra bits of special footage for one of them. I hope it won’t be too long now before I call them finished.

On top of that business, I’ve been communicating with several filmmakers about ideas and material for the History Channel show The Universe. (I’ve told you about […] Click to continue reading this post →

Best Abstract of the Year So Far?

By | | , , ,

…At least in my field, as submitted to the ArXiv. Just saw “Remarks on the world-sheet saga” by Bert Schroer. The abstract (and the paper) is full of excellently derisive turns of phrase that are hilarious to read! Example from the abstract:

Attention is given to how such misleading metaphors originate and how their support is maintained by quantum mechanical analogies to models which for good reasons never existed before in particle physics physics and whose only purpose is to uphold the string metaphor. The correct localization is inconsistent with the idea of world-sheets and the string-theoretical interpretation of T-duality.

He’s not actually trying to make the reader laugh, I think, but is attempting to make some serious physics points in there, apparently suggesting alternative lines of […] Click to continue reading this post →

Just Great!

quantum_criticalI’ve no idea why I’m writing a blog post about this, since I can’t really explain any of the details in a way that won’t sound tediously technical. I’m just pleased since I had a sort of perfect workshop moment for a couple of hours after the weekly picnic at the Center today. I’d been talking a bit last week with Lincoln Carr, an excellent condensed matter theorist at the Colorado School of Mines, and had also been talking with Allan Adams, another excellent physicist, from MIT. Allan and I seem to be on the same page as theorists and so I really enjoy talking with him. We work on string theory, but are not fussy about where the physics that it can be applied to might come from. As long as it is good physics. We both seem to love the idea that there’s so much rich physics, that might be accessible with string theory,[…] Click to continue reading this post →

Haunting while Working

Well, there are two Aspen cafes that are probably a bit sick of me. The last couple of days saw me frequenting one or other of them while I worked on a number of things, primarily finishing writing a paper. I’ve focused on little else but finishing it up so that I can get on with other things, such as my various other projects, and also to allow me to pay attention to the interesting talks coming up in the workshop […] Click to continue reading this post →

Uses For Strings?

viscosity_scatterThere were a couple of string theory stories in New Scientist last week. I forgot to mention them earlier. One is entitled “What string theory is really good for”, by Jessica Griggs. The other is entitled “Why cats fail to grasp string theory”, by Ewen Callaway.

Well, since cats are involved, of course I’m going to start with an extract from the second (even though it is obvious that the cats are deliberately skewing the results):

[…] Osthaus’s team attached fish or biscuit treats to one end of a string. A plastic screen with a small gap at the bottom separated cats from their reward, requiring the felines to tug on the string to get the treat.

With a single string attached to the food, most cats learned to paw at the string to get a snack. But when Osthaus’ team introduced a second piece of string, […]

Well, that was to pique your interest. You’ll have to go off to the source article to get to grips of this second piece of stringy research. The first article? It’s a discussion of […] Click to continue reading this post →

An Odd Time

watchWell, it was an unusual day here in Aspen. It was a day with lots of talks. Six of them, I think. There were four workshop talks scheduled for the morning, each of half an hour I think. Also got into a discussion before the sessions began, helping to explain how gauge/gravity duals work to a condensed matter colleague. I checked a voicemail message (only a relatively limited set of people have my number and so I figured it was a call to which I’d want to respond) and, despite the fact that I’m in retreat mode and would normally ignore it, returned the call. It was an office at USC wanting to put me in touch with a journalist who needed help. From Esquire. No, it is not what you think. I suggested they can could call me at 13:05, and at 10:30 went to the talks.

Somehow, successive speakers kept running over time due to lots of (actually, pretty interesting) interruptions and discussions, so I did not mind that we got to 12:50, and my talk, which was scheduled for 12:00-12:30, had not happened yet. With […] Click to continue reading this post →

Ink Time…

ink_break_aspenAh, time to relax a bit after a somewhat busy last couple of days glued to the notebook and computer. The results? (1) A hasty colloquium to an audience of mixed expertise to try to get across a sense of why some of us are excited about various applications of string theory to a diverse range of physics including ongoing experiments in nuclear physics and condensed matter physics (the person who was going to do it was a bit ill apparently so I stepped in with some hastily prepared slides… a bit messy but hopefully some use)… (2) Two papers with my student Tameem on applications of string theory techniques to superconductivity (one will appear on the ArXiv in about 20 minutes if you are interested [update: it is here.])… (3) Notes for a talk I’ll give on Thursday about said new results… (4) Several discussions with and ideas sent to some documentary film makers about some new TV shows coming up – Season 4 of The Universe! Seems I’ll get involved in some of them (stay tuned)…

So this morning I went to sit and cool down a bit at a cafe I like to visit a lot when in Aspen. Ink Coffee. Ok, I see that I did not yet mention I was in Aspen. Have been for […] Click to continue reading this post →

lhc_and_mont_blancJester at Resonaances reports on a talk by Jörg Wenninger about the progress at the Large Hadron Collider (LHC).

There’s information about the repairs, more thoughts about the accident last year, and somewhat frightening news about issues of quality control on some of the manufacturing of crucial parts that may haunt the entire project for some time to come. […] Click to continue reading this post →

Remind Me Not To Do This Again…

film_notesI’ve just finished two days of staring for long stretches at the computer screen, reviewing all my footage for the films, (see also here) making careful notes about which takes I like, which I don’t, which are salvageable, which are a total mess, suggestions for cut away shots, transitions, other edits, etc, etc, etc… These notes are for my film editor, who will now take the hard drive of all the footage to begin cutting the first rough versions of the films.

It was a time-consuming process, with the additional complication from the fact that the Industry is in some disarray when it comes to high definition (HD) formats. Largely due to the explosion of technology, the move to, and the demand for the format from the consumer TV world, there is no universal standard for how different camera manufacturers (and even the different models of a given manufacturer) save the files they make, and for how to get those files safely and reliably off the camera and on to your computer in a way that allows you to view them.

Fair Play

Yesterday saw my annual stint of judging at the California State Science Fair. Somehow it managed to sneak up on me this year, and so I did not get to do what I planned to do, which is encourage one or two scientist/engineer friends of mine in the area to sign up to get involved, since it is such fun and quite rewarding (ahem: Michelle P., Amy M., mark your calendars for next year! I’m going to come a-calling…) See earlier posts (e.g., here, here) for science fair descriptions, and the fair’s own site with lots of photos each year is here.

(Ok, there’s the whole getting up in time to arrive there by 7:00am or so. That bit is less than good, perhaps.) I arrived a bit later than 7:00, due to some breakfast procrastination that science_center_parkingI somehow sometimes manage to do even when I wake up with plenty of time (a whole hour this time) to get ready. My plan to simply set out by 6:10am and pleasantly walk/bike and bus down (my usual mode) was thwarted by this and so I had to take a somewhat quicker mode of transport, launching out of the batcave in a hurry at 6:50am! By 7:15am the parents and students in their SUVs and minivans were arriving at the California Science Center in droves, and so this meant that parking was a bit more of a challenge that it would have been 15 minutes earlier. But as you can perhaps see on the right (click for larger view), it all worked out in the end… ( 🙂 )

Here’s a shot of the annual morning briefing of the volunteer judges (all well fed, […] Click to continue reading this post →

Professors Do It Too

Remember a couple of weeks ago I was mentioning an outbreak of schoolboy(-like) giggles from my physics 408b class due (it turns out, if you did the homework on the equation) to some audience-perceived off-colour hidden joke in some of the material I was presenting? (I’m still a bit embarrassed since I had no intention of making the joke they saw.) Well, just a couple of days later, I was witness to it again, but this time it was in a lecture by someone else, and the audience was mostly professors, and it was one of my esteemed colleagues who couldn’t help himself and broke out giggling. Well, actually, there was a short loud guffaw which burst out. So you see, even the fine upstanding citizens can submit to juvenile giggles.

Let me tell the story. We had the eminent evolutionary biologist Patricia Gowaty (UCLA) give an excellent talk entitled “Darwin and Gender”, as part of the College […] Click to continue reading this post →

Unintended Giggles

Quick question:

So, has anyone else, while teaching a class, heard a breakout of schoolboy giggles behind them upon sketching the typical shape of the spatial intensity of the synchrotron radiation from a charged particle? You know, this:

As soon as I drew it and heard the giggles I knew what they were getting at. I had not anticipated it at all. It did not help that I drew it in the more exaggerated fashion that […] Click to continue reading this post →

Making Movies, 2

still_from_shoot_5_smallReally, I suppose this should be entitled “Making Movies, 1”, but I think that the earlier post “Call Me Cecil…” is morally the post of that title. Several days of insanity later (from worrying more about insurance, to locking in locations, worrying we would not get the HD cameras in time, trying to find a PA for the shoot, negotiating with various parties here and there about various things – in between the usual activities of physics professoring), the first big shoot day came. That was yesterday.

It was a day with record (for the date) heat (90+, in F), which was not helpful, but overall it was fun. On Thursday, in my location scout mode, I was to be found popping over once every hour or so to a particular location on campus and taking a snapshot. Why? I wanted to see where the sun would be at what time, so that we could figure out exactly when we could use the location, and for what shots. The sun […] Click to continue reading this post →

Call Me Cecil…

…Well, just for a 24 hour period or so.

Why? Well, it’s just that one of the many projects I’ve not yet had time to report to you about is inching along, growing ever more involved, has been sucking up a huge amount of time recently, and is going to go really large this week.

What’s “going large”?

Ok, here goes. I’ve been taking a turn at being a filmmaker, on and off, for over a year now. I hope that the products of this will be coming to a theatre near you one day soon (probably your computer), but let’s not get ahead of ourselves. What is it? Much more later, but I’ll just say now that it’s got science, and it is educational and – I hope – fun.

So far, what have I been doing? Writing a script, sketching storyboards, waving my arms about trying to explain the concept to actual filmmakers (you know, ones who […] Click to continue reading this post →
