I linked to this on Twitter, where people enjoyed it. Don’t want folks who are still stuck in 2008 and only reading the blog to miss out. Abstruse Goose, click for legible original:

Eugene Lim was one of my first graduate students at the University of Chicago. We violated Lorentz invariance together (it’s not as dirty as it sounds), and he’s since gone on to think about bubble collisions and eternal inflation at prestigious places like Yale, Columbia, and Cambridge.
But Eugene always cared about other things in addition to physics, and today he’s bringing us a guest post about a heart-wrenching topic: education in Haiti in the aftermath of their devastating earthquake. Not content to agitate for support from the comfort of his computer, Eugene is actually hopping on a plane this weekend to spend a month teaching math at a poor rural university. Here’s his introduction, and we hope to have a follow-up post after he returns from his travels.
———-
On Tuesday, January 12, 2010 at 4:53pm, a massive quake hit Haiti, killing an approximate quarter of a million people, injuring another quarter of a million, and causing massive infrastructure damage. Today, more than five months later, as the news cycle has moved on, Haitians are still pulling themselves out of the disaster, with 1.5 million people still homeless.
Fondwa is the 10th Communal Section of Leogane situated about 60 km south of the Haitian capital, Port-au-Prince, near the epicenter of the quake. It is a rural community with big dreams, the peasants banded together in 1988 to form the APF (Association of Peasants of Fondwa) to create a model community, not just with the aim of providing basic services but to empower the people of Haiti by providing them with the education and knowledge to improve their own lives.
One of their amazing achievement is the founding of a university, the University of Fondwa (UNIF) in 2004 in the mountains of Haiti, offering majors in Management, Agricultural Engineering and Veterinary Science — skills necessary for a rural community to survive and thrive — with about 40 students from all over Haiti. They graduated their first class last year.
The quake destroyed all the buildings of UNIF : the main building, the dorms and the lecture halls. Remarkably, classes continued after the quake, first in tents, and hopefully soon in temporary shelters. Final exams were given and graded, and the new semester began on schedule, May 5.
I met the founder of the University, Fr. Joseph Phillipe in New York a few weeks ago (he also founded Haiti’s biggest microfinance bank, FONKOZE, but that’s another story) — a series of hopeful email inquiries inspired by the watching a documentary about Fondwa led to having coffee with him in uptown New York City. Despite the challenges that his community is facing, he was full of energy, focusing on what to do for the future. I was impressed. I told him I want to help out.
I told him I wanted to volunteer to teach in UNIF, but I was not sure what I need to do. He said “We are waiting for you in Fondwa.”
This week, I am headed down to Fondwa to teach math for a month. I was told to be prepared to be caught unprepared. Internet permitting, I hope to post a follow-up to this when I get to Fondwa with more pictures from the ground.
A month is not exactly a long time. But I hope that any help is better than no help at all — they are short on teaching staff after the quake. Personally, I have been inspired by humanitarian groups like Doctors without Borders and Paul Farmer’s Partners in Health. I can’t save lives as a doctor, but I can teach! A long term hope is to be able to build ties in Fondwa, and perhaps do this on a yearly basis. I believe that academics have a lot to contribute in making this world a better place beyond hanging out in our ivory towers.
I asked Fr. Joseph what else I can do to help, he said “Tell your friends about us, and ask your friends to come too”.
Sean has kindly allowed me to use this blog to publicize the plight of the community at Fondwa. They are still trying to get basic services in. Their main needs are monetary donations, temporary housing, clean water and volunteers! They are especially looking for long term volunteers for six months of longer. They are also looking for a President for UNIF — I am serious — if you are interested or know anybody who might be interested, email APF below.
If you like want to volunteer, the best way is to contact APF directly at apf222@aol.com or go to the APF homepage. If you like to donate directly to APF click on the link to my blog for the bank information. If you want help out Haitians to help themselves : support Fonkoze’s microfinancing efforts by helping out here.
Ah, not this one again. The folks at Iglu Cruises have put together a helpful infographic to explain various features of the Gulf of Mexico oil spill (via Deep Sea News). Here’s the bit where they compare the recent spill (which, by the way, is still ongoing at a fantastic rate) to previous oil spills. Click for full resolution.
Doesn’t make the current fiasco seem so bad, does it? That little blob on the left looks a lot smaller than the blob right next to it, representing Saddam Hussein’s dump of oil into the Persian Gulf during the first Gulf War. In fact, when you think about it, it looks a lot smaller. Which is weird, when you look at the numbers and see that the current spill is 38 million gallons (as of May 27), while the Iraqi spill was 520 million gallons, a factor of about 14 times bigger. The blob representing Iraq’s spill seems a lot more than 14 times the size of the blob for the current spill. You don’t think — no, they couldn’t have done that. Could they?
Yes, they did. When measure the diameter of the circle representing the Iraqi spill, I get about 360 pixels (in the high-res version), while the smaller spill is about 26 pixels — a factor of about 14 larger. But that’s the diameter, not the area. The area of a circle, as many of us learned when we were little, is proportional to the square of its radius: A = π r2. The radius is just half the diameter, so the area is proportional to the diameter squared, not to the diameter. In other words, that big blob is about (14)2 = 196 times the area of the little one, when it should be only 14 times bigger.
I remember reading on some other blog about this same mistake being made in a completely different context, but I have no recollection of where. (Update: it was at Good Math, Bad Math, sensibly enough.) Probably won’t be the last time.
Here’s a local issue that reflects a very common set of problems: the Los Angeles subway system. Such as it is. Namely, embarrassingly inadequate. Our aspirations to be considered a world-class city on the level of New York, Paris, Tokyo or London are severely restricted by the difficulties people face in getting around without a car. Or with a car, for that matter, given the traffic.
But there’s no reason it has to be like this. At any given moment, some concerned group of citizens will be agitating to improve the situation. Right now such a group is Get L.A. Moving. They’ve put together an amazing proposal for a serious subway network that would utterly transform the city, while respecting the natural contours of the existing urban environment. Click for bigger versions.
Looking at a map like this is a bittersweet experience — comparing what could be to what is. Of course it would be very expensive; they estimate about $35 billion, which doesn’t sound so crazy when spread over a number of years. Times are tough — but that’s exactly the reason why pie-in-the-sky plans like this should be taken seriously right now. There’s no better way to stimulate the economy than to pour massive amounts of money into legitimate infrastructure projects; you create jobs, but you also create value that lasts for many decades to come. Not to mention decreasing our reliance on fossil fuels, which hopefully doesn’t need to be justified.
Also — how cool would it be to have one of these babies crawling along underneath Sunset Boulevard?
In the back of my mind, the real obstacle to building a subway system in a mature city was that you couldn’t really imagine shutting down long stretches of busy streets for months or years at a time. But you don’t have to; modern tunnel-boring technology does it all underground.
Some will object that LA just isn’t dense enough to support a subway system; our attractions are spread out rather than localized to squares. That’s an utterly backwards attitude; build the subway, the density will come. With nice weather 340+ days a year, this is the perfect city in the world to have a mass transit system connecting a bunch of pedestrian-friendly outdoor plazas.
Of course, then everyone would want to come live here. So maybe it wouldn’t be ideal. But it would still be a good idea for the economy and the environment; so I’m willing to sacrifice.
SpaceX, a private company that is developing the capability to launch both manned and unmanned missions into space, today successfully launched their Falcon 9 launch vehicle into orbit from Cape Canaveral in Florida. This is the rocket that is designed to eventually deliver Dragon spacecraft to low Earth orbit, including to the International Space Station. It was quite a thrill to watch the launch live on webcam — there was one little glitch that delayed the flight at the very moment of planned launch, but they quickly recovered and made a successful attempt within today’s launch window. Congratulations to SpaceX!

A couple of weeks ago we heard news that the Tevatron at Fermilab, soon to be superseded by the LHC at CERN as the world’s cutting-edge high-energy particle accelerator, might not be completely out of surprises just yet. The D0 experiment released results that seemed to indicate an asymmetry between the properties of matter and antimatter, at a level just a smidgen above what you need to claim a statistically significant result. Blogs started chattering right away, of course, but this was big enough news to be splashed across the front page of the New York Times.
The measurement concerns the decay of B mesons — particles consisting of one bottom (b) quark and one lighter antiquark, or vice-versa. If the other quark is a down, the corresponding meson Bd is electrically neutral, as is its antiparticle. They can therefore practically indistinguishable, and can oscillate back and forth between each other. The one difference is that the meson and anti-meson decay a little bit differently; this has been studied in great detail at B-factories, with results that have been very useful in determining values of parameters in the Standard Model of Particle Physics.
The new D0 results use a different kind of particle — the Bs meson, in which a strange quark rather than a down quark is stuck to the bottom quark. They measured the relative rate of decay of the Bs and its antiparticle, and found a discrepancy that appears inconsistent — barely — with the Standard Model. In particular, they looked at decays that produced muons or anti-muons.
The Center for Inquiry is a great organization — their mission is to “foster a secular society based on science, reason, freedom of inquiry, and humanist values,” which sounds like a good idea to me. They sponsor a number of activities including lectures, education, conferences, and research. I’ve given talks at the local branch, and it’s a great thrill to meet with such an engaged and enthusiastic audience.
And they’re in a bit of trouble. As a non-profit, they rely on donations, and their major donor seems to have mysteriously disappeared. About $800,000 of their annual operating budget is suddenly gone.
We’re not going to make up for that with a few appeals on the internet, but we can help them adapt during a tough time. Consider donating, even if it’s just a few bucks.
I have to agree with Jerry Coyne here: the program on Faith and Science at this year’s World Science Festival is a mistake. I went to last year’s Festival, and I have great respect for Brian Greene and Tracy Day for bringing together such a massive undertaking. It would be better if they didn’t take money from the Templeton Foundation, but money has to come from somewhere, and I’m not the one paying the bills. I don’t even mind having a panel that talks about religion — it’s a big part of many people’s lives, and there are plenty of issues to be discussed at the intersection of science and religion.
But it would be a lot more intellectually respectable to present a balanced discussion of those issues, rather than the one that is actually lined up. The panelists include two scientists who are Templeton Prize winners — Francisco Ayala and Paul Davies — as well as two scholars of religion — Elaine Pagels and Thupten Jinpa. Nothing in principle wrong with any of those people, but there is a somewhat obvious omission of a certain viewpoint: those of us who think that science and religion are not compatible. And there are a lot of us! Also, we’re right. A panel like this does a true disservice to people who are curious about these questions and could benefit from a rigorous airing of the issues, rather than a whitewash where everyone mumbles pleasantly about how we should all just get along.
I’m not as much of an anti-Templeton fundamentalist as some people are; I won’t take money from them, but I will cooperate with institutions and organizations that do take money from them, even as I grumble about it. (Money laundering as the route to moral purity.) But this event is a perfect example of the ultimately pernicious influence that Templeton has. I disagree with Jerry and others who consider Templeton money a “bribe” to people who are willing to go along with their party line; I have no doubt that Ayala, Davies, Pagels and Jinpa will express only views that they sincerely hold and would still hold in the absence of any monetary reward. What Templeton does is that it hands people with those views a giant megaphone. Francisco Ayala is a respected scientist who happens to believe that science and religion complement each other rather than coming into conflict; that’s fine, although somewhat unremarkable. But then he wins the Templeton Prize, and that exact same opinion gets plastered all over the media.
Panels like this one at the WSF are the same story. Maybe exactly the same event would have been organized even if Templeton had nothing to do with the Festival; but I doubt it. (Update: upon reflection, I don’t know what the process was by which the event was organized, and I shouldn’t cast dark aspersions in the absence of evidence. My real point is that I don’t think that the panel should have happened the way it did, and I don’t want to detract from that.) Plenty of science festivals and museums seem to get along perfectly well without discussing religion at all. And if you did want to discuss it, there’s no way that an honest investigation into how scientists feel about religion would end up leaving out some fully committed atheists who would be pretty uncompromising towards belief.
Four hundred years after Galileo turned his telescope on the heavens, it’s incredibly frustrating that we still have debates over whether the world can be described in purely naturalistic terms, rather than accepting that insight as an amazing accomplishment and moving on to the hard work of articulating its consequences. It’s a shame that the World Science Festival is helping to keep us back, rather than moving us forward.
One of the many places I’ve been traveling to recently is a bit unusual: the Linda Hall Library in Kansas City, Missouri. For one thing, it’s a private library; like the Huntington Library in Pasadena, it’s supported almost entirely by private funds. For another, Linda Hall is completely dedicated to science, technology, and engineering. While visiting, I asked what they considered their peer institutions to be — the other science libraries they might be compared to. Nobody could think of any. It seems to be a completely unique place.
I got to tour deep into the bowels of the building, where stacks of journals and scientific reports seem to stretch for ages. The library does a brisk job lending books and articles to other institutions; when you need a technical note from 1923 that tells you how a certain bridge was put together, this is the place to go. There is also an amazing rare-book collection, some of which was being put on display as part of an exhibition entitled “Thinking Outside the Sphere: Views of the Stars from Aristotle to Herschel.” I got to leaf through a first edition of Newton’s Principia, which I have to say was pretty awesome. I didn’t find any mistakes, but my Latin is a bit rusty. Here are the three Laws of Motion, right near the beginning of the text.
The library also adds to the intellectual life of Kansas City by sponsoring public lectures. I followed Sara Seager and Seth Shostak in a series about extraterrestrial life. Not my area of expertise by any means, but they asked me to talk about time travel, which I do know something about. (At least by the standards of other human beings, for which neither “time travel” nor “extraterrestrial life” are subjects of true expertise anywhere.)

Of course I also had some BBQ while in KC. One does not live by the life of the mind alone.
3 Quarks Daily has embarked on an annual hunt for the best blog posts in four areas: science, politics, philosophy, and arts & literature. Nominations have now opened for this year’s science prize; you have until May 31 to suggest your favorite science blog post from the last year; then there will be a round of public voting, and a final award bestowed by a celebrity judge. Last year the science prize was awarded by Steven Pinker; this year it will be Richard Dawkins. Someday I’m sure they’ll work their way up to having a physicist serve as judge.
Feel free, of course, to nominate your favorite posts from Cosmic Variance; I’m far too shallow to be reluctant to win awards. But even better would be to find a really great post at a smaller blog that not as many people know about, and use this contest as a vehicle for bringing more attention to really good writing. There’s too much good stuff out there, it’s impossible to follow all of it, so it’s always nice to hear about new bloggers doing great things.
