You’ll notice that I often talk about alternatives to driving everywhere in Los Angeles. Sometimes I talk about bikes (see for example the last post) as part of a range of options. Well, in December last year a student at USC doing a project in journalism (Lauren Lee – she’s at the Annenberg School) did a short report on bikes and the city for her project. (See also some of my posts about this issue, such as here, here, here, and several posts in the list at the bottom of this one). In her research, Lauren found this blog, gave me a call, and I agreed to make a few comments to camera for her as part of her larger report on some of the changes that are happening here in Los Angeles. (She also interviews Adam and Josef Bray-Ali, owners of the Flying Pigeon LA bike shop (hey, they have a blog)- a bike that might interest you.)
I should preface it with some remarks of my own. It is a nice report, but she edited out all the things I said that I think get at a central and key point. (To be fair, she was trying to make a two minute report, and I was babbling on enough for a Spike Lee four-part documentary…) I’m not advocating that everyone cycle everywhere they need to get to. Instead, I’m trying to get across the idea that cycling works really well in combination with the public transport system that already exists. One of the reasons people give most often for not using public transport is that the bus or subway stop is not quite close enough to where they want to get to, and/or close enough to their home. Leaving aside the cases where that sometimes this means “more than one block” or “not right next to my garage”, I’m trying to get across the […] Click to continue reading this post
Well, hey! I’m not the only one:

Today on NPR’s Morning Edition they played a piece by Madeline Brand that aired in 2007 about the Keeling curve, and the man behind the curve, Charles David Keeling. As you may know, the Keeling curve (above) is a striking demonstration of the steady increase in the concentration of carbon dioxide in the atmosphere, as measured from one location (on top of Mauna Loa in Hawaii) by one very simple method over almost 50 years.
It is a lovely story of dedication and determination that resulted in a simple, striking, […] Click to continue reading this post
With more refreshing words about what he thinks science is, and the role science can play in shaping society and steering the country forward, Barack Obama announced several key science posts today. One of them is a physicist by the way. (“Excellent…”, cvj rubs hands together with a gleam in his eye, “…all going according to plan.”)
Here’s a YouTube video of the announcement:

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
With the rise in gas prices, I’ve been seeing more and more people on the streets, walking and cycling, and more people using the subways and the buses. While I know that it has been producing real hardship for some people, I have to admit that it has been fantastic to see this change. So many streets and street corners have come to life. It has always been clear that higher gas prices would have this positive change, and I’ve hoped for it in some ways, but I wish that it had not come about in this way. I’d rather that it was because we’d managed to break out of a political climate so selfish and naive that nobody could propose raising taxes to an extent that would simultaneously give an incentive for people to use their cars less while at the same time providing much needed revenue with which to improve public transport infrastructure. Sadly, instead we’re just having high prices with nothing to show for it but a bunch of expressions of anger, while the oil companies and producers get fatter and fatter.
When I say I’d been hoping for higher prices, I need to clarify. I’m completely aware of […] Click to continue reading this post
So Chris and Sheril have announced the next step in the journey to a real debate about science issues of note that intersect with the current political sphere. And they’ve come a long way in a short time! Here’s some of what they said in a recent post:
ScienceDebate2008 is now co-sponsored by the American Association for the Advancement of Science, the National Academies, and the Council on Competitiveness. We were looking at venues, and finally settled on an offer from the Philadelphia-based Franklin Institute–named, of course, after one of this country’s first and greatest scientists. We can’t think of a more appropriate venue.
And guess what?! They’ve actually invited the candidates: Hillary Clinton, Mike Huckabee, John McCain, and Barack Obama.
So the next step is to get the event (they suggest April 18, 2008) taken seriously by the […] Click to continue reading this post
Ok, a sidestep into politics for a short, but important moment.
With all that’s going on with all the presidential debates and press conferences and other appearances, has anything struck you as a major topic (or class of topics) that is simply missing from the national discussion? A topic that affects our lives in so many ways, and helps shape our futures in a most profound manner?
I’m thinking of science. I’m thinking of it in all the forms in which it intersects with politics – where decisions made by the president involve policy directly related to science (climate change and stem cell research are two of the most obvious), scientific research (both basic and applied), safety and security issues (consider the EPA, Katrina and other natural disasters), resources (the ongoing and coming battles about water sources, for example, pollution and air quality go here too, as well as under other headings), and energy (well, take your pick of example issues there). There’s also science education, on which there ought to be coherent effort for many reasons […] Click to continue reading this post

There’s been some really excellent material over on Correlations. I recommend having a look. Among that, there’s been some very interesting posts about climate. The most urgent one is by Sheril, in which she reminds us about the behemoth, Cyclone Sidr, which is bearing down on Bangladesh right now, with potential human cost well beyond that of Katrina. One to watch.
The other posts I wanted to point to is the growing series of posts by Michael about climate science. People largely think of climate science in terms of the global warming arguments, but there’s a lot more to it than that. Michael’s trying to build an […] Click to continue reading this post
[Post reconstructed after 25.10.07 hack]: My Correlations colleague Michael Tobis has a nice, simple post about the difference between weather and climate that’s worth a look. He starts out: We climate scientists often hear the case made “If you can’t predict the weather next week, how could you predict the … Click to continue reading this post
Hey, guess who I saw today! Recall, that I passed a woman on a tricycle a while back? Well, at exactly the same spot, I passed her again today. She’s called Julia, as you may recall from her comment on the blog sometime later, (as I’d met her subsequently and said hello properly). I briefly said “hello and how are you” this time as our bike and trike passed each other, but I apologized for having to rush off, and rushed off. I was trying to catch the next bus in order to get to my classroom by 9:55am. The class’ first midterm was at 10:00 today and I wanted to make sure to be on time. So I dashed off to the stop…
…Only to be accompanied five minutes later by Julia, calmly arriving on her tricycle. She was also catching the same bus, it turned out, and I’d landed in the gap between buses and needed to wait anyway. After checking with me that this was indeed the stop she needed, she chained her splendid red machine to a tree. I contemplated taking a picture of us and the two extraordinary conveyances together to show you. However, while I dithered over this, the bus came. So I’ll cheat and re-use the old picture (right).
Anyway, we chatted quite a while about things (including the frustration of trying to […] Click to continue reading this post
[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
Interestingly, NASA’s chief administrator, Michael Griffin, apologized for his somewhat bizarre remarks of last week. What remarks? The ones that (among other things) essentially sidelined a huge amount of the work people in his own organization are busy with. See here for a reminder. He made his apology at JPL on Monday: […] Click to continue reading this post
