Friday random poetry

Lauren, keeper of the Friday Random Ten (or is it Roxanne? I can never remember), has hit upon a new bit of randomness on which to end your week: Rob’s Amazing Poem Generator. This poem came from the post on What people should know, comments included. I edited it slightly, for which I make no apologies.

What is far the Science
educator, I first
took as a course
contained all the atmosphere
Out which end this
in keeping with a different rest
my major religions
the immediate purpose of undergrads.
Let me a few hours downloading a
great organization, devoted to gather up
else if it’s
dogma,
They succeed in the Advancement of this
looking for good information
on science. simpler to be
seeing how science
is that
cloudy nights seem to get an embarassment
in the controversy.
cow methane. emitted from the physics students
to go a long way and come out
as you, but
publicly the real Nobody questions that.

Secret exciting blog news revealed

I try to tease you folks, but it’s hard to keep secrets from such a clever and persistent group of people. No, there aren’t any marriage plans on the horizon — it’s even better than that.

As some of you guessed, I’m happy to announce the launch of a new group blog:

Cosmic Variance

My co-bloggers include notorious Orange Quark proprietor Mark Trodden, former Preposterous guest-blogger Risa Wechsler, and two blogging neophytes, JoAnne Hewett and Clifford Johnson. As you will discover for yourself, they comprise quite the group of charismatic and irreverent raconteurs, and I’m sure the discussions will be both amusing and stimulating. Mark, like me, is a theoretical field theorist and cosmologist; Risa is an expert on the formation of galaxies and cosmological large-scale structure; JoAnne is one of the world’s leading particle phenomenologists; and Clifford works on string theory and M-theory, and (like me) has written a textbook to prove it.

Don’t let the fact that they are all physicists fool you. Although we each have our different voices and concerns, all of us at Cosmic Variance agree that we’ll spend some of our time talking about science, and a good amount of time talking about whatever else strikes our fancy. In particular, my Cosmic posting philosophy will be precisely the same as my Preposterous posting philosophy has been — there will just be some extra value-added from the interactions with new colleagues. (And, by the way, a much nicer blog layout and functionality, as some of these folks actually know what they’re doing.) I’m excited, this is going to be great fun.

As for the plucky old blog you’re reading here, what of its future? For the most part, I won’t be posting here very much — as I said, everything I might have posted will simply go to the new site. I will keep it around, as I will often have reason to refer to posts in the archives, as well as an understandable sentimental attachment. Perhaps I will occasionally post something here that I don’t want to sully my new collaborators with (although frankly I can’t imagine anything).

So, the blog is dead, long live the blog! Thanks to everyone for reading, and enjoy the new blogging ahead.

Update: the new blog already has one distinction to its name — it’s the place to go for news about Brad and Angelina.

The missing philosopher

The philosophical blogosphere is abuzz about a silly BBC poll to name the ten greatest philosophers of all time. (See Crooked Timber, 3quarksdaily, applecidercheesefudge, and links therein.) Now you know why history’s greatest thinkers, like the nation’s college football champions, should not be chosen by popular vote: Karl Marx came in first, while Aristotle couldn’t muster better than ninth.

I just wanted to point out that, in a world where disciplinary boundaries were drawn more rationally, the runaway winner would have been Sir Isaac Newton.

Slouching towards the Middle Ages

Some time back I suggested that Pope Benedict, the erstwhile Josef Ratzinger, may not have been the best choice to help Christianity broaden its appeal in secular Western societies. Condemning gay marriage and casting doubt on evolution, for starters, wouldn’t seem to be effective strategies. Now it appears he might be going for the trifecta: coming down against Harry Potter (via The American Sector).

I can just imagine the throngs of affluent secular Europeans, fed up with privacy rights and modern science and imaginative children’s literature, returning to the arms of the Church in droves. Another strategic setback for the atheist agenda.

Update: Okay, now it makes more sense.

GWOT

In the wake of a tragedy like the London bombings, it almost seems unseemly to note that it may have been preventable. Unseemly, but necessary.

Supporters of the Bush administration like to paint its critics as unwilling to take the steps necessary to combat terrorism. The truth is, we just want to combat it effectively. Invading countries unnecessarily, taking countless steps to flame anti-American sentiment around the world, and using terror alerts to political advantage are all part of a dishonest and woefully misguided mindset, one that puts many motivations higher than effective steps against the danger of terrorism.

Update: More discussion from Juan Cole, Metafilter, and Daily Kos.

The Cosmologist vs. The Cardinal

If you want something done, why not go to the top? That seems to be Lawrence Krauss’s strategy — he’s collaborated with two biologists to write a letter to the Pope asking him to clarify the Church’s stance on evolution.

This of course is in response to a New York Times editorial by Cardinal Christof Schönborn, in which he attempts to set straight anyone who might have thought that the Catholic Church was perfectly comfortable with evolution as understood by scientists. He doesn’t mince words, making it clear that Catholics should believe in what is now called “intelligent design”:

Ever since 1996, when Pope John Paul II said that evolution (a term he did not define) was “more than just a hypothesis,” defenders of neo-Darwinian dogma have often invoked the supposed acceptance – or at least acquiescence – of the Roman Catholic Church when they defend their theory as somehow compatible with Christian faith.

But this is not true. The Catholic Church, while leaving to science many details about the history of life on earth, proclaims that by the light of reason the human intellect can readily and clearly discern purpose and design in the natural world, including the world of living things.

Evolution in the sense of common ancestry might be true, but evolution in the neo-Darwinian sense – an unguided, unplanned process of random variation and natural selection – is not. Any system of thought that denies or seeks to explain away the overwhelming evidence for design in biology is ideology, not science.

I especially like that last sentence. We certainly wouldn’t want any sneaky ideology to get in the way of our purely scientific understanding of nature, would we?

As PZ says (and even the Times seems to have noticed), the Cardinal is simply repeating the party line of the Discovery Institute. Lawrence and his friends (Francisco J. Ayala and Kenneth R. Miller) are asking the Pope to reaffirm what most people thought was the case, that the Church had fully accepted the scientific theory of the development of life.

It’s hardly surprising that the Church might favor design over natural selection. The idea that God had something to do with the origin and nature of humanity is one that it would be difficult to give up on from a religious perspective. The letter from the scientsts to the Pope stresses “that in these difficult and contentious times the Catholic Church not build a new divide, long ago eradicated, between the scientific method and religious belief.” I wish Lawrence and his friends well, but I don’t think they’ll ultimately succeed; the fact is that there is such a divide, and all the Papal edicts in the world won’t make it go away.

Danger

Looks like American soldiers are once again allowed to walk around London, after a brief period in which they were forbidden to do so right after the bombings. No such luck for the physicists here at Saclay — word has come down from on high that nobody is allowed to travel to England for the time being, presumably out of fear of further attacks. This is quite a disruption, as the big SUSY 2005 conference is being held in Durham next week.

Any counter-terrorism experts out there are welcome to correct me, but this strategy seems exactly wrong. I would guess that the time right after an attack is the absolutely safest time to travel. Surely, everyone riding a bus or the Tube in London is going to be just as jumpy and suspicious in the weeks to come as Americans taking airplanes were after September 11. Not only would it be much harder to carry off an attack, but the terrorists undoubtedly know this themselves, and it seems unlikely that they would even try.

I won’t even bother to point out that, even including the successful attacks that have already occurred, the likelihood of being killed by terrorists is completely negligible compared to more mundane forms of danger. Death by subway bombing is so dramatic and horrible that it’s hard not to worry about it far out of proportion to the actual threat (much like comparing sharks to vending machines). So some bureaucrats in Paris (or wherever) will feel assured that they are doing their job if they prohibit scientists from traveling to Britain. After some time passes, they will decide that the danger has diminished, and we can resume talking about important things, like the predicted abundance of neutralino dark matter candidates in various supersymmetric extensions of the Standard Model.

The wine-dark sea

Sad times for Chicagoans and public-radio lovers everywhere: Odyssey, the noontime “talk show of ideas” on Chicago Public Radio, has been cancelled by the WBEZ board. Despite being syndicated to over 30 stations nationally, the show was judged to not quite be worth the cost.

This is a huge loss, as Odyssey was some of the most intelligent and stimulating conversation you could find on any sorts of airwaves. I admit that I’m biased: I’ve appeared on the show myself, and host Gretchen Helfrich was even a guest-blogger here at Preposterous. But just because I’m biased doesn’t mean I’m not right. The show offered serious and substantive discussion about intriguing issues with top-flight experts, often academics who were stars in their fields — a serious intellectual consideration of difficult ideas, not the kind of Crossfire-style empty babbling that Jon Stewart skewered so effectively. Consider some of the topics considered just in the last couple of weeks:

  • Founding America: Beyond The Fathers
  • Religious Meanings of the Ten Commandments
  • The Social History of Computers
  • Domesticating the American Man
  • Torture and Democracy
  • Identity Politics

Hell, they even had a show about blogging. Okay, but other than that, we’re talking about some really substantive discourse here.

Josh Andrews, senior producer of Odyssey, recently started blogging at The American Sector, where he talked a little about the shock of this decision. Here’s hoping that he and Gretchen and everyone at the show land on their feet — the airwaves will be a lot poorer without them.

Update: More comments from Henry Farrell at Crooked Timber. If you’d like to complain to WBEZ, write to Torey Malatia:

La Ville Lumière

One of my great regrets is that I have never learned to speak French. Just about every year I resolve that I’ll finally bite the bullet, I buy a new book or set of CD’s, and for a couple of weeks I make an honest effort, before being distracted by the rest of my life. So I can ask for coffee, and say “Je regrette, mademoiselle, mais je ne parle pas Francais,” but that’s about it.

I’m sure I would appreciate Paris much more if I spoke the language, but it’s still one of my favorite places to spend time. I’ve been here often enough that I feel absolutely no obligation to zoom around experiencing all the standard tourist fare — I’ve been to the museums and the churches, now I can just relax and enjoy the city. Of course, I’m not an energetic tourist by nature. There is a tour group staying in my hotel, and their schedules are posted by the elevator — “7:15 Wake up. 8:15 catch bus to Giverny.” People actually pay to fly around the world just so they can be catching a bus at 8:15?

For me, Paris is about wandering the streets randomly, peeking into art galleries and stopping frequently at cafes, biding time in between meals. Unless it’s a special occasion and you want to be fancy, there’s no point in planning ahead of time what restaurant you’d like to go to; as far as I can tell every street of Paris has about twenty restaurants per block (okay, a slight exaggeration), and part of the fun is stumbling across something unexpected. The best such experience I’ve had was with a couple of friends several years ago, when we cautiously entered a tiny establishment that looked almost cave-like with its white stucco walls. The proprietor, as it turns out, was also the piano player, and he became increasingly gregarious through the evening as he worked his way through a bottle or two of wine. He was quite the polyglot, and between songs he would sit at the tables of his customers and boast that he could converse with any of them in their native tongues. One of my friends was Finnish, so we stymied him. I have no recollection of the food, but the dinner was fantastic. Not that the cuisine is generally to be forgotten; last night I had a crepe with pate of foie gras and caramelized apples that I’ll remember for quite some time.

The perfection of cafe lifestyle is Paris’s finest achievement, not to mention Chicago’s greatest failure. (Even compared to the coasts, Chicago’s cafe scene is abysmal; it’s dominated by Starbucks, and the few remaining stragglers are generally too crowded or noisy to be comfortable.) How wonderful is it to be in a city with a choice of cafes on every corner, where one can sit inside or outside, linger indefinitely over a coffee or a glass of wine, and order food or not as one chooses. Of course I am fortunate enough that such behavior can actually qualify as work. Not only is it possible for me to bring along some papers and a notepad and happily scribble the equations that are a theoretical physicist’s stock in trade, I’m much more efficient in such surroundings than I am in my actual office.

Not that my visit is all patisserie and cafe au lait, goodness no. Last week I was attending a conference at the Institute d’Astrophysique de Paris on Mass Profiles and Shapes of Cosmological Structures. This may come as some surprise, as I know nothing of any interest about the mass profiles nor the shapes of cosmological structures. However, the organizers wanted to have a substantial discussion about whether dark matter could possibly be replaced by modified gravity. Although I haven’t worked on that problem directly (I’ve tried to replace dark energy, but never dark matter — please, I have my standards), I was able to give a mostly-competent review from the perspective of an interested outsider, to help negotiate between the skeptical astronomers and the other gung-ho modified-gravity theorists they had invited (including Milgrom himself).

And now this week I’m at the Service de Physique Theorique at Saclay, a 20-minute train ride south of Paris. I’m visiting Geraldine Servant, a former Chicago postdoc and now faculty at Saclay and expectant mother. (Christophe Grojean, at left in the picture, is the expectant father — congratulations to both of them!) We are working with some other friends on how to make dark energy at particle accelerators. Tentative answer: it’s hard to do. But you knew that already.
