[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.)
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
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:
In addition to some seminars, my day was filled up a bit more with some administration. I’m on a couple of committees that helps keep things ticking along […] Click to continue reading this post
This is another of the incredibly striking Dan Flavin sculptures that I saw at the retrospective at LACMA (the Los Angeles County Museum of Art) earlier this month.
The sheer blueness of it was particularly striking, I have to say. It was intense. I left the colours from neighbouring pieces at the edges of the image, since I think this helped set the blue in your visual field before you then walk into the corridor and immerse yourself in the blue. I think that helped enhance the blue, but I’m not sure. It was interesting to note that the blue was nowhere near as powerful when starting at the […] Click to continue reading this post
To a first approximation, this will not be funny at all to any of you:

A 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
So, has anyone who reads the blog used the new Velib system in Paris yet? A new layer of public transport has been rolled out (yes, I know) onto the streets of Paris, as of last Sunday (July 15th). The Bicycle. A publicly funded scheme (familiar to some from elsewhere, such as Lyon and Amsterdam (?), if memory serves) called “Velib” where there are special bike racks all over the city. One of the (charmingly European-looking) bikes is pictured on the right. From a BBC story by Emma-Jane Kirby:
The local authority in Paris has deposited 20,000 heavy-duty bicycles in 750 or so special racks around the city and anyone who wants one simply swipes his or her ordinary travel card and pedals off wherever they want to go.
The bike does not have to be returned to the same pick-up point – you can take a bike from a rack near the Eiffel Tower, cycle to the Pantheon and leave it in the nearest Velib stand there.
This sounds great, from my point of view, you’ll not be surprised to learn! I’m finding it hard to see a downside here at all. A bit more:
The Velib scheme is aimed at people who are making short journeys.
The first half hour of pedalling time is absolutely free but, if you fail to return the bike after 30 minutes, you get charged an extra euro and the penalties go up the later you are.
(So European… penalties. They could not find another, more positive word?)
The Velib website is here. And of course it is only in French. What did you expect? (Actually, it is rather entertaining to read, all the same, since it is mostly easy-to-guess French, and knowing the context helps.)
I can’t see what’s stopping such a system from being introduced in cities in America. I think that we should start with….. Los Angeles, of course! It is one of the cities that […] Click to continue reading this post

My previous hard case for the Brompton was getting battered to bits by the baggage handlers, was too big for the bike anyway (was an old hard-sided suitcase that I bought second hand for $50), but had put in good service for two years. Options: (1) Look for a new one by driving around lots of second hand luggage places again, finding another almost-fit, or (2) Pay the money for a purpose-built professional case that fits rather snugly (and is quite light) and have more peace of mind that the B’s going to be ok when it gets to the other side. It’s expensive, but will be worth it in the long run…
I picked (2):

….and I’ve just unpacked the B in Aspen, Colorado, and ten seconds later, it’s ready to ride!

Look in the “related posts” list below for some posts in which it makes at least a roll-on appearance.

Some interesting news about the outreach mission. From time to time, Asymptotia posts get picked up by some of the local blogs of note, such as LA Observed, and that’s just great, since many things I talk about here are right at the intersection of local interest and the arts and sciences, especially education (such as talking in a local school), events such as the Categorically Not! ones at Santa Monica Airport, and issues such as the environment, in addition to the pure fun stuff, and the tasty stuff. For example, Kevin Roderick at LA Observed was kind enough to mention the posts about the Griffith Observatory (the new relaunch, and the controversy about the use of actors in the planetarium show), judging at the Science Fair at the California Science Center, as well as the post on the open day at the Jet Propulsion Laboratory, and the post about cycling in the city (perhaps in combination with public transportation, as an alternative to blindly using your car/SUV for most journeys.)
Well, I was pleased to get an email a few days ago telling me that Outside.In have added added Asymptotia to their list of LA neighbourhood blogs, and the posts will be scanned for local references, and then added to a location map of all blogs posts. So what happens is that you can look at a neighbourhood in Outside.In (I tailored the previous link to 90089, the zip that USC is in, for example) and see marks on a map where blog posts have pointed to, or lists of posts that pertain to a particular zip code or neighbourhood. You can then follow those marks back to the blog posts! It’s very cool indeed. This will work for your neighbourhood too, where ever you are (in the USA) – just put in your zip code.
Each blog in the system also has their own page, and the one for Asymptotia is here. You should go to it to experiment with the clickability, but I also took a screen shot (since I can’t see how to live-embed the map), and so this is it earlier:
So far it seems a bit inconsistent with picking things up and I don’t know why, – it might […] Click to continue reading this post
I’m conflicted. I read the first Harry Potter book and decided that while it is a good thing that many people are reading more as a result of them, I could not really recommend it highly as great work because it’s just so derivative. Having grown up reading all those boarding school books J. K. Rowling borrowed from (for example) without adding anything to them much, I was frustrated.
Well, of course, in the scheme of things, it does not matter. Not all things we like have to be Great Works. And I eventually convinced myself that there’s nothing wrong with people (who did not read those works that she’s imitating) discovering the genre for themselves in the pages of her books. Then others told me that the books got better. 
They got darker, and more grown up (do they approach the excellence and relative originality of the once largely ignored Philip Pullman books I wonder?), and better written, I’ve been told, by people whose opinion I trust. Well, good.
The films came out and they were all very ho-hum and then happily Chris Columbus stopped directing them after the first two and – Wow! They were suddenly really rather good. (The third one was by the wonderful Alfonso Cuarón, so – of course!) (Clickable above right for clarity: Extract from my own attempt to tap into the mania some years back by using characters from the books/films to illustrate the derivation of time dilation in a class on Special Relativity.)
Anyway, I saw the fifth one last night, and I was very impressed with it as a film. Not having read the book, I find myself hoping that there was more to it than the film, since it still seems all rather derivative. There’s a bit of 1984 and a lot of Lord of the Rings mixed in with the Boarding School motif. I suspect that’s all as a result of stripping it down to look for something to hang a film on? I’m going to assume that, since there’s an awful lot of transparent (but entertaining) dark motifs about the […] Click to continue reading this post
Or becoming less “pants†every day. Fantastic! On Wednesday, the House appropriations committee repealed the ridiculous and trumped-up 1986 Congressional ban on tunneling to complete the Wilshire subway line project. This was pushed through by Congressman Waxman, the same person who misguidedly got the ban instated in the first place. Funny how nimby-ness (and, arguably, fear of people who don’t look like you getting access to your neighbourhood) about public transportation projects crumbles when you finally realize that your SUV is at a standstill in traffic more often than not…. and all you were doing was driving five blocks to get a pint of milk from Whole Foods. (Found a bit more here on LAist.)
The Purple line right now is either two stops long, or several stops long depending upon how you count. (Click on map to right to see what I mean.) It’s effectively two, since all the other stops are Red line stops – it just runs two stops more to the West stopping a few long block away at Wilshire/Western. Hence the post title, expressing the hope that it will be several stops long, all the way out to the Pacific. It would be just great to go all the way to Santa Monica from downtown on a train. Why is that not obviously a super-wonderful thing to be able to do? Dinner and drinks on the Santa Monica pier at Sunset followed by a concert in the Disney Hall. No faffing about with traffic and over-priced parking. Is that not a dream worth running toward with open arms?
Next step, finding a ridiculous amount of money to build the thing because an […] Click to continue reading this post
Confession: I’ve no idea what Torchwood is, and I find the current Dr. Who shows annoying overall (there have been some good episodes that I’ve seen, but they’re swamped in a sea of such poorly thought through and simply phoned-in crappy episodes that I find it too annoying to take the risk of wasting an hour I could have better spent with my head in the oven…) Feel free to disagree with me, and I have not seen the most recent season, so maybe things are better.
But anyway, where was I? Oh, right. Someone called John Barrowman (apparently one of the stars on those shows? He plays a scientist? I honestly don’t know, but you will, if you’re a fan) took a visit to CERN (the particle physics lab in Europe you often read about here and elsewhere) to better inform himself about the intersection between science and science fiction. One of the resulting jumpy noisy and (reportedly) fun videos can be found on YouTube here. There are some somewhat interesting animations alongside some of the, er…jolly madcap fun, illustrating the physics. Following the particles along the beam-pipe to the collision is not a view I’ve seen before, I’ll admit.
Much more interesting is something they mention at the end. A series of podcasts on the LHC (the big experiment at CERN we’re all interested in and excited about). This is driven by Brian Cox (no, not that one, this one, the physicist), and seems to be in a […] Click to continue reading this post
